Description: GitHub repositories were compromised, leading to the exposure of install action tokens which fortunately had a limited 24-hour lifespan, thus reducing the risk of widespread exploitation. Endor Labs found that other sensitive credentials like those for Docker, npm, and AWS were also leaked, although many repositories adhered to security best practices by referencing commit SHA values rather than mutable tags, mitigating the potential damage. Despite the reduced impact, due to the potential for threat actors to leverage GitHub Actions, users are advised to implement stricter file and folder access controls to enhance security measures and prevent similar incidents in the future.
Description: The GitVenom campaign has aggressively targeted gamers and crypto investors, utilizing GitHub as a platform for hosting malicious projects. With a multitude of fake repositories that contained harmful code, the campaign has deceived users with seemingly legitimate automation tools and crypto bots. The impact of GitVenom included credential theft, unauthorized cryptocurrency transactions, and remote system control through backdoors. The damage extended to personal data compromise and financial losses for the affected users, while also tarnishing GitHub's reputation as a safe space for developers to share code.
Description: An unknown attacker is using stolen OAuth user tokens to download data from private repositories on Github. The attacker has already accessed and stolen data from dozens of victim organizations. Github immediately took action and started notifying all the impacted users and organizations about the security breach.
Description: A network named Stargazer Goblin manipulated GitHub to promote malware and phishing links, impacting the platform's integrity by boosting malicious repositories' popularity using ghost accounts. These activities aimed to deceive users seeking free software into downloading ransomware and info-stealer malware, compromising user data and potentially causing financial and reputational harm to both GitHub and its users. GitHub’s response was to disable accounts in violation of their policies and continue efforts to detect and remove harmful content.
Description: The **Banana Squad** threat group, active since April 2023, compromised over **60 GitHub repositories** by trojanizing them with **malicious Python-based hacking kits**. These repositories masqueraded as legitimate hacking tools but contained **hidden backdoor payloads**, designed to deceive developers and security researchers into downloading and executing them. The attack leveraged **supply-chain compromise tactics**, exploiting GitHub’s open-source ecosystem to distribute malware under the guise of trusted repositories. The campaign, uncovered by **ReversingLabs**, revealed that the fake repositories mimicked well-known tools, embedding **stealthy backdoor logic** that could grant attackers unauthorized access to systems, exfiltrate data, or deploy further payloads. While the **direct financial or operational damage to GitHub itself remains undisclosed**, the incident poses **severe reputational risks** to the platform, eroding trust among developers who rely on GitHub for secure code sharing. Additionally, **downstream victims**—developers or organizations that unknowingly integrated the trojanized tools—face potential **data breaches, system compromises, or lateral attacks** stemming from the malicious payloads. The attack underscores vulnerabilities in **open-source supply chains**, where threat actors exploit **typosquatting and repository spoofing** to distribute malware. Though no **large-scale data leaks or ransomware demands** were reported, the **deception-based nature of the attack** and its potential to enable **follow-on cyber intrusions** classify it as a **high-severity reputational and operational threat** to GitHub’s ecosystem.
Description: The **GhostAction attack** compromised **327 GitHub accounts**, leading to the theft of **3,325 secrets**, including **PyPI, npm, DockerHub, GitHub tokens, Cloudflare, and AWS keys**. The attack began with the hijacking of the **FastUUID project**, where the maintainer’s account was breached to inject a malicious **GitHub Actions workflow** named *‘Add Github Actions Security workflow’*—designed to exfiltrate sensitive credentials. GitGuardian detected the campaign, reported it to GitHub, and disrupted the operation by rendering the exfiltration server unresponsive. While **100 of 817 affected repositories** reverted malicious changes, **573 repositories** were alerted via issue notifications (others were deleted or had issues disabled). The attack exposed **API keys, access tokens, and deployment secrets**, risking downstream supply-chain compromises. A separate but unrelated **NPM-based *s1ngularity* attack** hit **2,000 accounts** concurrently, though no overlap was found between victims.
Description: GitHub was hit by a major DDoS attack that made the website unavailable to many users for several hours. The attackers injected malicious JavaScript code into the pages of those websites that were responsible for the hijacking of their visitors to Github. Github investigated the incident and removed several repositories to secure its servers.
Description: A sophisticated **typosquatting attack** targeted GitHub via a malicious npm package **‘@acitons/artifact’** (mimicking the legitimate **‘@actions/artifact’**), accumulating **206,000+ downloads** before removal. The attack exploited developers mistyping dependency names, deploying a **post-install hook** that executed obfuscated malware undetected by antivirus tools (0/60 on VirusTotal at discovery). The malware, compiled via **Shell Script Compiler (shc)**, checked for **GitHub-specific environment variables** (e.g., build tokens) and exfiltrated **authentication tokens** from GitHub Actions workflows. These tokens could enable attackers to **publish malicious artifacts under GitHub’s identity**, risking a **cascading supply chain compromise**. The campaign used **hardcoded expiry dates** (Nov 6–7, 2023) and **AES-encrypted exfiltration** via a GitHub App endpoint, evading detection. The attack directly threatened **GitHub’s CI/CD infrastructure**, with potential downstream risks to **repositories, developers, and enterprise customers** relying on GitHub Actions. While GitHub removed the malicious packages and users, the incident highlights critical vulnerabilities in **dependency trust models** and the escalating threat of **supply chain attacks** (OWASP Top 10 2025).
Description: The GitHub Desktop for Mac and Atom programs, GitHub confirmed that threat actors exfiltrated encrypted code signing certificates. Customer data was not affected, the company claimed, because it was not kept in the affected repositories. According to the business, there is no proof that the threat actor was able to use or decrypt these certificates. According to the business, neither GitHub.com nor any of its other services have been affected by the security compromise.
Description: GitHub, the top software development platform in the world, made some users reset their passwords after discovering an issue that resulted in credentials being recorded in plain text in internal logs. A routine corporate audit uncovered the problem, which involved some users sharing on Twitter the email correspondence that the organisation had received. The business promptly stated that user data was safe and that none of its systems had been compromised. The business further stated that the plaintext passwords were not publicly available and could only be seen by a limited number of its IT workers through internal log files.
Description: GitHub experienced a ransomware attack which include at least 392 GitHub repositories. Some users who fell victim to this hacker have admitted to using weak passwords for their GitHub, GitLab, and Bitbucket accounts. However, all evidence suggests that the hacker has scanned the entire internet for Git config files, extracted credentials, and then used these logins to access and ransom accounts at Git hosting services. It was found that Hundreds of developers have had Git source code repositories wiped and replaced with a ransom demand.
Description: A critical vulnerability in Git CLI enables arbitrary file writes on Linux and macOS systems, allowing attackers to achieve remote code execution through maliciously crafted repositories when users execute git clone –recursive commands. This vulnerability, assigned a CVSS severity score of 8.1/10, exploits a flaw in Git's handling of configuration values and carriage return characters. Public proof-of-concept exploits are available, and urgent remediation is required across development environments.
Description: GitHub’s **Copilot Chat**, an AI-powered coding assistant, was found vulnerable to a critical flaw named **CamoLeak** (CVSS 9.6), allowing attackers to exfiltrate secrets, private source code, and unpublished vulnerability details from repositories. The exploit leveraged GitHub’s invisible markdown comments in pull requests or issues—content hidden from human reviewers but parsed by Copilot Chat. By embedding malicious prompts, attackers tricked the AI into searching for sensitive data (e.g., API keys, tokens, zero-day descriptions) and encoding it as sequences of 1x1 pixel images via GitHub’s **Camo image-proxy service**. The attack bypassed GitHub’s **Content Security Policy (CSP)** by mapping characters to pre-generated Camo URLs, enabling covert data reconstruction through observed image fetch patterns. Proof-of-concept demonstrations extracted **AWS keys, security tokens, and private zero-day exploit notes**—material that could be weaponized for further attacks. GitHub mitigated the issue by disabling image rendering in Copilot Chat (August 14) and blocking Camo-based exfiltration, but the incident highlights risks of AI-assisted workflows expanding attack surfaces. Unauthorized access to proprietary code and vulnerability research poses severe threats to intellectual property and supply-chain security.
Description: A vulnerability within GitHub's CodeQL, a security analysis tool, was uncovered that had the potential to be exploited, potentially affecting a vast number of public and private repositories. Despite there being no evidence of actual misuse, the flaw could have allowed for the exfiltration of source code and secrets, jeopardizing the security of internal networks including GitHub's own systems. The vulnerability, which involved the exposure of a GitHub token, was quickly addressed by the GitHub team, showcasing their rapid and impressive response.
Description: Microsoft's Azure DevOps server was compromised in an attack by the Lapsus$ hacking group.

Some of the compromised data contain emails and documentation that were clearly used internally by Microsoft engineers.
Description: Some of the sensitive information of Microsoft customers was exposed by a misconfigured Microsoft server accessible over the Internet in September 2022. The exposed information includes names, email addresses, email content, company name, and phone numbers, as well as files linked to business between affected customers and Microsoft or an authorized Microsoft partner. However, the leak was caused by the "unintentional misconfiguration on an endpoint that is not in use across the Microsoft ecosystem" but the SOCRadar claimed to link this sensitive information to more than 65,000 entities from 111 countries stored in files dated from 2017 to August 2022.
Description: A significant security breach has compromised Microsoft’s PlayReady Digital Rights Management (DRM) system, exposing critical certificates that protect premium streaming content across major platforms including Netflix, Amazon Prime Video, and Disney+. The leak involved the unauthorized disclosure of both SL2000 and SL3000 certificates, with SL3000 representing a particularly severe security concern. These certificates utilize advanced hardware-based security measures designed to protect the highest quality content, including 4K and Ultra High Definition releases. The compromise undermines the fundamental trust model upon which DRM systems operate, posing a critical threat to the entire digital entertainment ecosystem. TorrentFreak researchers noted that the leaked SL3000 certificates could facilitate large-scale content redistribution networks, significantly escalating piracy capabilities.
Description: Microsoft mitigated a record-breaking **15.72 Tbps** distributed denial-of-service (DDoS) attack in late October 2023, the largest ever recorded against its Azure cloud platform. The multivector assault, peaking at **3.64 billion packets per second**, originated from the **Aisuru botnet**, exploiting compromised home routers and IoT cameras across **500,000+ source IPs** globally. While the attack targeted a single Australian endpoint, Azure’s DDoS Protection infrastructure successfully filtered and redirected traffic, preventing service disruption or data compromise. No customer workloads were affected, and operations continued uninterrupted.The attack was part of a broader surge in DDoS activity linked to Aisuru and related **TurboMirai botnets**, which had previously executed **20+ Tbps 'demonstration attacks'** primarily against internet gaming organizations. Microsoft attributed the escalation to rising residential internet speeds and the proliferation of connected devices, enabling attackers to scale attacks proportionally with global infrastructure growth. Though no data was breached or systems compromised, the incident underscored the evolving threat landscape of hyper-scale DDoS attacks leveraging vulnerable IoT ecosystems.
Description: Microsoft’s Azure network was targeted by the **Aisuru botnet**, a Turbo Mirai-class IoT botnet exploiting vulnerabilities in routers, IP cameras, and Realtek chips. The attack peaked at **15.72 Tbps** (terabits per second) with **3.64 billion packets per second**, originating from over **500,000 compromised IP addresses**—primarily residential devices in the U.S. and other regions. The DDoS assault leveraged **UDP floods** with minimal spoofing, targeting a public IP in Australia. While Azure mitigated the attack, the botnet’s scale and persistence posed significant risks to service availability, network integrity, and customer trust. The same botnet was linked to prior record-breaking attacks (e.g., **22.2 Tbps** against Cloudflare in September 2025), demonstrating its evolving threat capability. The incident also revealed Aisuru’s manipulation of Cloudflare’s DNS rankings by flooding its **1.1.1.1 service** with malicious queries, distorting domain popularity metrics.

Description: Microsoft suffered severe outages for some of its services, including Outlook email, OneDrive file-sharing apps, and Azure's cloud computing infrastructure. The DDoS attacks that targeted the business's services were allegedly carried out by a group going by the name of Anonymous Sudan (also known as Storm-1359). In a report titled Microsoft Response to Layer 7 Distributed Denial of Service (DDoS) assaults, the IT giant later acknowledged it had been the target of DDoS assaults. Still, he did not disclose further information regarding the outage. The business emphasized that they had not found proof of unauthorized access to or compromise of client data.
Description: Microsoft detected Chinese threat actors employing the Quad7 botnet, also known as CovertNetwork-1658 or xlogin, in sophisticated password-spray attacks aimed at stealing credentials. These attacks targeted SOHO devices and VPN appliances, exploiting vulnerabilities to gain unauthorized access to Microsoft 365 accounts. The botnet, which includes compromised TP-Link routers, relayed brute-force attacks and enabled further network exploitation. Affected sectors include government, law, defense, and NGOs in North America and Europe. The attackers, identified as Storm-0940, utilized low-volume password sprays to evade detection and maintained persistence within victims' networks for potential datapoints exfiltration.
Description: Microsoft Teams, a globally adopted collaboration platform, has become a prime target for cybercriminals and state-sponsored actors exploiting its messaging, calls, meetings, and screen-sharing features. Threat actors leverage open-source tools (e.g., **TeamFiltration, TeamsEnum, MSFT-Recon-RS**) to enumerate users, tenants, and misconfigurations, enabling reconnaissance and initial access. Social engineering tactics—such as **tech support scams (Storm-1811, Midnight Blizzard), deepfake impersonations, and malvertising (fake Teams installers)**—trick users into granting remote access, deploying ransomware (e.g., **3AM/BlackSuit, DarkGate**), or stealing credentials via **device code phishing (Storm-2372)** and **MFA bypass (Octo Tempest)**. Post-compromise, attackers escalate privileges by abusing **Teams admin roles**, exfiltrate data via **Graph API (GraphRunner) or OneDrive/SharePoint links**, and maintain persistence through **guest user additions, token theft, and malicious Teams apps**. State-sponsored groups like **Peach Sandstorm** and financially motivated actors (**Sangria Tempest, Storm-1674**) exploit cross-tenant trust relationships for lateral movement, while tools like **ConvoC2** and **BRc4** enable C2 over Teams channels. Extortion tactics include **taunting messages to victims (Octo Tempest)** and disrupting operations by targeting high-value data (e.g., **employee/customer PII, patents, or financial records**). The attacks undermine organizational trust, risk **regulatory penalties**, and enable **supply-chain compromises** via federated identities. Microsoft’s mitigations (e.g., **Entra ID Protection, Defender XDR alerts**) highlight the platform’s systemic vulnerabilities, with ransomware and data leaks posing existential threats to targeted entities.
Description: Microsoft disrupted **RaccoonO365**, a phishing-as-a-service operation led by Joshua Ogundipe, which stole **at least 5,000 Microsoft 365 credentials** across **94 countries** since July 2024. The service, sold via Telegram (850+ members), offered subscriptions ($335–$999) to bypass MFA, harvest credentials, and maintain persistent access—enabling **financial fraud, ransomware, and larger cyberattacks**. The stolen data was resold to criminals, while Ogundipe profited **$100,000+ in crypto**. Targets included **2,300+ US organizations** (tax-themed phishing) and **20+ healthcare providers**, prompting Health-ISAC to join Microsoft’s lawsuit. Though 338 domains were seized and Cloudflare dismantled the infrastructure, Ogundipe (Nigeria-based) remains at large. The operation’s **AI-powered scaling (RaccoonO365 AI-MailCheck)** and capacity to process **9,000 email targets/day** amplified risks of **data breaches, extortion, and supply-chain attacks** leveraging compromised Microsoft accounts.
Description: In 2026, a low-level breach in Microsoft’s cloud infrastructure—part of the global computing backbone—was exploited by threat actors, cascading into a large-scale disruption. The attack targeted a widely deployed firewall vulnerability, compromising SaaS platforms that power critical enterprise ecosystems. This led to a domino effect, exposing sensitive data across one-eighth of the world’s networks, including financial records, proprietary business intelligence, and government-linked communications. The breach triggered outages in cloud services relied upon by Fortune 500 companies, halting operations for banks, healthcare providers, and logistics firms. While no direct ransomware was deployed, the incident eroded public trust, prompted regulatory investigations, and forced Microsoft to implement emergency patches. The economic fallout included contractual penalties, lost revenue from service downtime, and a surge in cyber insurance premiums for affected partners. Analysts warned that the attack highlighted the risks of concentrated infrastructure dependency, with nation-state actors suspected of probing for future escalations.
Description: The database that drives m.careersatmicrosoft.com was handled by a mobile web development company that Microsoft relied on, and it was accessible without any authentication for a few weeks. All signs pointed to the database, which was a MongoDB instance, not being write-protected. Therefore, an attacker may have altered the database and, as a result, the HTML code of the job listing pages throughout the disclosed time period. Everything was secured once Chris Vickery informed Punchkick and Microsoft of the issue.
Description: Microsoft experienced massive data breach affecting anonymized data held on its customer support database. The data breach affected up to 250 million people as a result of the tech giant failing to implement proper protections. The information compromised included email addresses, IP addresses and support case details.
Description: A massive dump of Microsoft's proprietary internal builds for Windows 10 has been published online, along with the source codes for proprietary software. This is the largest leak affecting Windows products; the data in the dump were probably stolen from Microsoft computers in March. Microsoft's Shared Source Kit, which comprises the source code for the Microsoft PnP and base Windows 10 hardware drivers as well as storage drivers, USB and Wi-Fi stacks, and ARM-specific OneCore kernel code, has been released. Top-secret versions of Windows 10 and Windows Server 2016 that have never been made public are included in the dump.
Description: The VSCode Marketplace, operated by Microsoft, suffered a security lapse when two extensions embedding in-development ransomware bypassed the review process. These extensions, downloaded by a handful of users, aimed to encrypt files within a specific test folder and demanded a ransom in ShibaCoin. While the impact was minimal due to the ransomware's limited scope, it revealed significant gaps in Microsoft's review system. This incident sheds light on potential vulnerabilities within widely used developer platforms and highlights the importance of stringent security measures to prevent such breaches.
Description: The **Rhysida ransomware gang** exploited **malvertising** to impersonate **Microsoft Teams** in search engine ads (Bing), tricking users into downloading a fake installer laced with **OysterLoader malware** (also known as Broomstick/CleanUpLoader). The campaign, active since **June 2024**, used **typosquatting** and **code-signing certificates** (over 40 in the latest wave) to bypass antivirus detection, with some malware samples evading **VirusTotal** for days. Once executed, the loader deployed **Rhysida ransomware**, encrypting systems and exfiltrating data for extortion. Rhysida operates as a **RaaS (Ransomware-as-a-Service)**, with affiliates conducting attacks under the core group’s infrastructure. Since **2023**, they’ve leaked data from **~200 organizations** (27 in 2024 alone), targeting those refusing ransom payments. Microsoft revoked **200+ malicious certificates** tied to this campaign, but the gang’s **obfuscation techniques** (packing tools, delayed AV detection) ensured persistent infections. The attack chain—from **fake ads to ransomware deployment**—demonstrates a **highly coordinated, evolving threat** leveraging **trust in Microsoft’s brand** to compromise enterprises globally.
Description: A critical race condition vulnerability (CVE-2025-55680) in Microsoft Windows Cloud Minifilter (cldflt.sys) allowed attackers to exploit a time-of-check time-of-use (TOCTOU) weakness during placeholder file creation in cloud synchronization services like OneDrive. By manipulating filenames in memory between validation and file creation, attackers could bypass security checks and write arbitrary files—including malicious DLLs—to restricted system directories (e.g., *C:\Windows\System32*). This enabled privilege escalation to **SYSTEM-level access**, permitting arbitrary code execution.The flaw stemmed from inadequate filename validation in the *HsmpOpCreatePlaceholders()* function, a regression linked to a prior patch (CVE-2020-17136). Exploitation required only basic user privileges, posing severe risks to multi-user environments. Microsoft addressed the issue in the **October 2025 security updates**, but unpatched systems remained vulnerable to attacks leveraging DLL side-loading techniques. Organizations using cloud sync services with configured sync root directories were at heightened risk, as these were prerequisites for successful exploitation. The vulnerability carried a **CVSS 3.1 score of 7.8 (High)** and threatened system integrity, confidentiality, and availability through unauthorized privilege escalation.
Description: Microsoft encountered a security challenge when EncryptHub, also known as SkorikARI, a threat actor emerged with skills in vulnerability research. The actor, credited by Microsoft for uncovering two Windows security issues, could potentially compromise users' safety and data. The vulnerabilities, identified as high-severity CVE-2025-24061 and medium-severity CVE-2025-24071, raised concerns over the Mark of the Web security feature and Windows File Explorer, respectively. EncryptHub's background in ransomware and vishing, combined with these recent activities, signifies a mixed threat profile.

Description: Cybersecurity researchers at **Check Point** uncovered four critical vulnerabilities in **Microsoft Teams** (tracked as **CVE-2024-38197**, CVSS 6.5) that enabled attackers to manipulate conversations, impersonate high-profile executives (e.g., C-suite), and forge sender identities in messages, calls, and notifications. The flaws allowed malicious actors—both external guests and insiders—to alter message content without the 'Edited' label, modify display names in chats/calls, and exploit notifications to deceive victims into clicking malicious links or disclosing sensitive data. While Microsoft patched some issues between **August 2024 and October 2025**, the vulnerabilities eroded trust in Teams as a collaboration tool, turning it into a vector for **social engineering, data leaks, and unauthorized access**. The attack chain leveraged Teams’ messaging, calls, and screen-sharing features, enabling threat actors (including cybercriminals and state-sponsored groups) to bypass traditional defenses by exploiting **human trust** rather than technical breaches. Though no confirmed data breaches were reported, the risks included **credential theft, financial fraud, and reputational damage**—particularly if employees or customers fell victim to impersonation scams. Microsoft acknowledged Teams’ high-value target status due to its global adoption, warning that such spoofing attacks could escalate into broader **phishing campaigns or lateral movement** within corporate networks.
Description: The Cybersecurity and Infrastructure Security Agency (CISA) identified **CVE-2025-59230**, a critical **privilege escalation vulnerability** in **Windows Remote Access Connection Manager**, being actively exploited in real-world attacks. This flaw allows threat actors with limited system access to **elevate privileges**, execute malicious code with administrative rights, **exfiltrate sensitive data**, and move laterally across networks. While no direct data breach or ransomware linkage has been confirmed, the vulnerability poses severe risks if chained with other exploits—potentially enabling **full system compromise**, unauthorized data access, or disruption of operations. CISA mandated federal agencies to patch within **three weeks**, emphasizing the urgency due to active exploitation. Organizations failing to remediate risk **unauthorized access to confidential information**, **operational disruptions**, or **follow-on attacks** like data theft or ransomware deployment. The flaw’s exploitation could lead to **financial fraud, reputational damage, or regulatory penalties** if sensitive data is exposed or systems are hijacked for malicious purposes.
Description: Microsoft disclosed **CVE-2025-59499**, a critical **SQL injection vulnerability** in **SQL Server** that enables authenticated attackers to escalate privileges remotely over a network. The flaw (CWE-89) arises from improper neutralization of SQL commands, risking unauthorized administrative access to enterprise databases. With a **CVSS 3.1 score of 7.7–8.8**, it poses a high-risk threat due to its **network-based attack vector**, low exploitation complexity, and lack of user interaction requirements. Successful exploitation could lead to **data manipulation, exfiltration, or deletion**, compromising confidentiality, integrity, and availability. Although Microsoft assesses exploitation as *‘Less Likely’* currently, the vulnerability’s **high-impact potential**—coupled with its appeal to insider threats or credential-compromised actors—demands urgent patching. Organizations handling **sensitive or critical data** in SQL Server environments are particularly exposed. The absence of public PoC exploits or confirmed wild attacks does not mitigate the risk, as sophisticated adversaries may weaponize it once technical details emerge. Microsoft advises **immediate patching**, access control reviews, and monitoring for suspicious privilege escalation attempts to prevent database takeovers.
Description: Microsoft faced a cyberattack where the CVE-2024-21412 vulnerability in the Defender SmartScreen was exploited to deliver information stealers such as ACR Stealer, Lumma, and Meduza, affecting users in Spain, Thailand, and the US. Attackers utilized crafted links to bypass security features and install malware that stole data and targeted specific regions. Despite Microsoft releasing a patch for the vulnerability, the attack compromised personal and potentially sensitive information. Organizational cybersecurity defenses were challenged by the innovative methods used by the attackers, underscoring the criticality of awareness and proactive security measures.
Description: In May, Microsoft introduced Recall, an AI that takes screenshots every five seconds for user convenience. However, concerns were raised about privacy and security, leading to delayed launch and modifications. Despite these changes, Tom's Hardware testing revealed the 'filter sensitive information' feature failed to prevent gathering sensitive data. Specifically, Recall captured credit card numbers, social security numbers, and other personal data while filling out a Notepad window and a loan application PDF, compromising users' financial information and privacy.
Description: A critical **token validation failure (CVE-2025-55241, CVSS 10.0)** in **Microsoft Entra ID (formerly Azure AD)** was discovered by researcher **Dirk-jan Mollema**, enabling attackers to **impersonate any user—including Global Administrators—across any tenant** without exploitation evidence. The flaw stemmed from **improper tenant validation in the deprecated Azure AD Graph API** and misuse of **S2S actor tokens**, allowing **cross-tenant access** while bypassing **MFA, Conditional Access, and logging**.An attacker exploiting this could **create admin accounts, exfiltrate sensitive data (user info, BitLocker keys, tenant settings, Azure subscriptions), and fully compromise services** like **SharePoint Online, Exchange Online, and Azure-hosted resources**. The **legacy API’s lack of logging** meant **no traces** of intrusion would remain. Microsoft patched it on **July 17, 2025**, but the **deprecated API’s retirement (August 31, 2025)** left lingering risks for un migrated apps.Security firms like **Mitiga** warned of **full tenant takeover risks**, emphasizing how **misconfigurations in cloud identity systems** (e.g., OAuth, Intune, APIM) could lead to **lateral movement, privilege escalation, and persistent access**—exposing **enterprise data, financial records, and operational control** to silent, high-impact breaches.
Description: The **CVE-2025-59287** vulnerability in **Windows Server Update Services (WSUS)** is under active exploitation by threat actors, including a newly identified group (**UNC6512**). The flaw, stemming from **insecure deserialization of untrusted data**, allows **unauthenticated remote code execution (RCE)** on vulnerable systems running WSUS (Windows Server 2012–2025). Despite Microsoft’s emergency patch, attackers continue exploiting it, with **~100,000 exploitation attempts detected in a week** and **~500,000 internet-facing WSUS servers at risk**. Attackers leverage exposed WSUS instances (ports **8530/HTTP, 8531/HTTPS**) to execute **PowerShell reconnaissance commands** (e.g., `whoami`, `net user /domain`, `ipconfig /all`) and **exfiltrate system data** via Webhook.site. While current attacks focus on **initial access and internal network mapping**, experts warn of **downstream risks**, including **malicious software distribution via WSUS updates** to enterprise systems. The flaw’s **low attack complexity** and **publicly available PoC** make it a prime target for opportunistic threat actors. Microsoft’s **failed initial patch** (October Patch Tuesday) and delayed acknowledgment of active exploitation exacerbate risks, leaving organizations vulnerable to **large-scale compromises**. The potential for **supply-chain attacks** via WSUS—used to push updates to thousands of endpoints—poses **catastrophic downstream effects**, though full-scale damage remains unquantified.
Description: A zero-day remote code execution vulnerability named 'Follina' in Microsoft Office discovered recently has the potential for code execution if a victim opens a malicious document in Word. The vulnerability abuses the ability of MSDT to load other assistants “wizards” in Windows, which in turn have the ability to execute arbitrary code from a remote location. It can also allow the attacker to view and edit files, install programs and create new user accounts to the limit of the compromised user’s access rights. The initial versions spotted in the wild required the target to open the malicious document in Word, but the recently discovered variant uses Rich Text Format (.RTF) works only if the user simply selects the file in Windows Explorer. Microsoft has yet not issued a patch but has suggested disabling the MSDT URL Protocol to cut off the attack sequence.
Description: In March 2021, Microsoft encountered a massive security breach that affected over 30,000 organizations in the U.S., ranging from businesses to government agencies.

The attack methodology leverages built-in system automation features, making it difficult to detect and mitigate. Security teams are advised to disable preview panes and block SMB traffic to prevent such attacks.
Description: Hello and welcome to 2-Minute Tech Briefing from Computerworld. I'm your host Arnold Davick, reporting from the floor of the New York Stock Exchange. Here are the top IT news stories you need to know for Tuesday, December 2nd. Let's dive in! First up from NetworkWorld. Microsoft is facing new pressure in its AI infrastructure push. This comes after losing two senior leaders responsible for data center and energy strategy, Nidhi Chappelle, head of AI infrastructure, and Sean James, Senior Director of Energy and data center research, both announced their departures, while Chappelle has not announced her next move. James is heading to Nvidia, intensifying competitive heat in the GPU arms race. Their exits come as Microsoft grapples with power constraints grid interconnection delays and the challenge of sourcing enough accelerators to meet skyrocketing demand. And from InfoWorld, Google has rolled out major updates to its Gemini API. The changes are designed to support the newly released Gemini 3 model. The improvements include simpler controls for managing the model's thinking. A new parameter called thinking level lets developers choose how deeply Gemini reasons before responding.

Lessons Learned: Difficulty in tracking SAS tokens due to lack of centralized management in Azure interface.

Lessons Learned: Importance of robust cybersecurity defenses and the need for constant vigilance

Lessons Learned: Criticality of awareness and proactive security measures

Lessons Learned: Importance of stringent security measures in review processes.

Lessons Learned: Modern computing environments’ emphasis on user convenience creates silent execution paths that require no interaction, fundamentally challenging traditional security assumptions about file-based attacks and necessitating a reevaluation of how systems handle passive file processing.

Lessons Learned: Ensure timely updates to software, monitor for suspicious git operations, and audit repository contents before cloning.

Lessons Learned: Open-source maintainer accounts are high-value targets for supply-chain attacks., Malicious CI/CD workflows can bypass traditional security controls., Proactive monitoring of public repositories can disrupt attacks early., Automated secret detection tools (e.g., GitGuardian) are critical for mitigating credential leaks.

Lessons Learned: Open-source repositories can be weaponized for supply chain attacks even in cybersecurity tooling., Developers must verify the integrity of third-party tools, especially those from untrusted sources., Threat actors exploit the trust in popular platforms (e.g., GitHub) to distribute malware.

Lessons Learned: Legacy APIs (e.g., Azure AD Graph) can introduce critical vulnerabilities if not properly deprecated or secured., Cross-tenant access risks in cloud identity systems require robust tenant isolation and token validation., Lack of API-level logging can enable stealthy exploitation without detection., Conditional Access and MFA can be bypassed if underlying identity validation mechanisms are flawed., Proactive migration from deprecated services is essential to mitigate emerging risks.

Lessons Learned: Phishing-as-a-service operations can scale rapidly with low barriers to entry (subscriptions as low as $335)., MFA bypass techniques remain a critical vulnerability in credential-based attacks., Operational security lapses (e.g., exposed cryptocurrency wallets) can aid attribution., Collaboration between tech companies (Microsoft/Cloudflare) and sector-specific ISACs (Health-ISAC) enhances disruption efforts., AI-powered phishing tools (e.g., RaccoonO365 AI-MailCheck) increase attack sophistication and scalability.

Lessons Learned: AI-assisted tools like Copilot Chat expand the attack surface by introducing new input channels (e.g., hidden markdown) that bypass human review. Content Security Policies (CSP) and proxy services (e.g., Camo) can be weaponized for covert exfiltration if not properly restricted. Developer workflows integrating AI require stricter input validation and output monitoring to prevent prompt injection and data leakage.

Lessons Learned: Privilege escalation vulnerabilities are critical as they enable deeper system access when chained with initial access exploits., Rapid patching is essential to mitigate active exploitation, especially for vulnerabilities added to CISA’s KEV catalog., Federal agencies must adhere to BOD 22-01 timelines to avoid compliance risks.

Lessons Learned: Race conditions in validation logic can reintroduce vulnerabilities even after prior patches (e.g., CVE-2020-17136)., Cloud synchronization services introduce attack surfaces that require rigorous input validation, especially for file operations., Time-of-check time-of-use (TOCTOU) vulnerabilities can be exploited with multi-threaded techniques to bypass security controls., Privilege escalation via DLL side-loading remains a persistent risk when attackers can write to system directories.

Lessons Learned: Incomplete patches can increase risk by creating a false sense of security., Internet-facing WSUS servers should be strictly controlled or disabled., Proof-of-concept (PoC) availability accelerates exploitation by opportunistic actors., Monitoring for reconnaissance commands (e.g., PowerShell) is critical for early detection.

Lessons Learned: Malvertising remains an effective initial access vector, especially when abusing trusted brands like Microsoft Teams., Code-signing certificate abuse can bypass security controls, requiring proactive revocation by CAs., Obfuscation techniques (e.g., packing tools) can delay AV detection, emphasizing the need for behavioral-based defenses., RaaS models like Rhysida enable rapid scaling of attacks with varied malware (OysterLoader, Latrodectus)., Typosquatting and fake download pages exploit user trust in search engines and legitimate software.

Lessons Learned: Collaboration platforms like Teams are as critical as email and equally exposed to social engineering risks., Threat actors can exploit trust mechanisms without needing to 'break in'—they only need to 'bend trust'., Organizations must secure not just systems but also what people believe (e.g., verification over visual trust)., Vulnerabilities in widely used tools like Teams can have cascading impacts across global enterprises.

Lessons Learned: Importance of maintaining robust database security practices, Necessity of regular patching schedules for critical systems, Value of access control reviews and continuous monitoring of database activity, Urgency in addressing network-accessible vulnerabilities with high impact potential

Lessons Learned: Typosquatting remains effective for supply chain attacks despite awareness., Obfuscation techniques (shc, encrypted C2) can evade AV detection (0/XX on VirusTotal)., GitHub Actions environment variables are high-value targets for token theft., Short-lived malware (self-termination dates) complicates detection., CI/CD pipelines require stricter dependency verification (e.g., package signing, allowlists).

Lessons Learned: IoT devices remain a critical attack vector for large-scale DDoS botnets., Firmware update servers (e.g., TotoLink) are high-value targets for botnet expansion., DNS query volume rankings can be manipulated by malicious traffic, requiring proactive redaction., Collaboration between cloud providers (Microsoft, Cloudflare) is essential for mitigating record-breaking attacks.

Lessons Learned: DDoS attacks are scaling with internet infrastructure upgrades (e.g., fiber-to-home, IoT proliferation)., Botnets like Aisuru/TurboMirai pose persistent threats by exploiting unsecured IoT devices., Cloud-native DDoS protection (e.g., Azure’s scrubbing services) is critical for mitigating large-scale attacks., Residential ISPs are increasingly targeted as attack launchpads.

Lessons Learned: Concentrated infrastructure risk (e.g., Microsoft/Amazon/Google backbones) is the biggest vulnerability, not just technology., AI agents introduce unique risks due to autonomy and broad access, requiring non-human zero-trust models., Identity sprawl and static authentication are no longer viable; continuous verification is essential., Compliance can drive innovation if treated as a framework for stakeholder trust and responsible AI/data use., The cybersecurity talent pipeline is critically thin, exacerbated by AI eliminating entry-level roles., Optional MFA and shared responsibility models in cloud security are no longer sufficient.

Key Lessons Learned: The key lessons learned from past incidents are Difficulty in tracking SAS tokens due to lack of centralized management in Azure interface.Importance of robust cybersecurity defenses and the need for constant vigilanceCriticality of awareness and proactive security measuresImportance of stringent security measures in review processes.Modern computing environments’ emphasis on user convenience creates silent execution paths that require no interaction, fundamentally challenging traditional security assumptions about file-based attacks and necessitating a reevaluation of how systems handle passive file processing.Ensure timely updates to software, monitor for suspicious git operations, and audit repository contents before cloning.Open-source maintainer accounts are high-value targets for supply-chain attacks.,Malicious CI/CD workflows can bypass traditional security controls.,Proactive monitoring of public repositories can disrupt attacks early.,Automated secret detection tools (e.g., GitGuardian) are critical for mitigating credential leaks.Open-source repositories can be weaponized for supply chain attacks even in cybersecurity tooling.,Developers must verify the integrity of third-party tools, especially those from untrusted sources.,Threat actors exploit the trust in popular platforms (e.g., GitHub) to distribute malware.Legacy APIs (e.g., Azure AD Graph) can introduce critical vulnerabilities if not properly deprecated or secured.,Cross-tenant access risks in cloud identity systems require robust tenant isolation and token validation.,Lack of API-level logging can enable stealthy exploitation without detection.,Conditional Access and MFA can be bypassed if underlying identity validation mechanisms are flawed.,Proactive migration from deprecated services is essential to mitigate emerging risks.Phishing-as-a-service operations can scale rapidly with low barriers to entry (subscriptions as low as $335).,MFA bypass techniques remain a critical vulnerability in credential-based attacks.,Operational security lapses (e.g., exposed cryptocurrency wallets) can aid attribution.,Collaboration between tech companies (Microsoft/Cloudflare) and sector-specific ISACs (Health-ISAC) enhances disruption efforts.,AI-powered phishing tools (e.g., RaccoonO365 AI-MailCheck) increase attack sophistication and scalability.Teams is a High-Value Target: Its integration with Entra ID, Graph API, and collaboration features makes it a lucrative attack vector for both commodity and advanced threat actors.,Social Engineering Remains Effective: Deepfakes, impersonation (IT help desk, external partners), and urgency-based scams (e.g., email bombing) bypass technical controls.,Default Configurations Are Risky: Over-permissive external access, unmonitored API queries, and legacy authentication enable initial access and lateral movement.,Open-Source Tools Lower the Barrier: Frameworks like TeamFiltration, AADInternals, and ROADtools democratize Teams exploitation for less-skilled attackers.,Hybrid Environments Complicate Security: On-premises AD synced with Entra ID creates seams for attackers to exploit (e.g., Peach Sandstorm’s AD snapshots).,MFA Is Not a Silver Bullet: Actors like Octo Tempest bypass MFA via social engineering (e.g., password resets, SIM swapping) or token theft.,Third-Party Apps Introduce Risk: Spoofed or malicious Teams apps (even Microsoft-validated ones) can serve as initial access vectors.,Detection Gaps Exist: Many Teams-specific attacks (e.g., phishing via Adaptive Cards, C2 over Teams messages) evade traditional email/security tools.,Incident Response Must Be Teams-Aware: Logs from Teams, Graph API, and Entra ID are critical for forensics but often underutilized.,User Awareness Is Critical: Employees must scrutinize Teams messages/calls as rigorously as emails, especially from 'internal' sources.AI-assisted tools like Copilot Chat expand the attack surface by introducing new input channels (e.g., hidden markdown) that bypass human review. Content Security Policies (CSP) and proxy services (e.g., Camo) can be weaponized for covert exfiltration if not properly restricted. Developer workflows integrating AI require stricter input validation and output monitoring to prevent prompt injection and data leakage.Privilege escalation vulnerabilities are critical as they enable deeper system access when chained with initial access exploits.,Rapid patching is essential to mitigate active exploitation, especially for vulnerabilities added to CISA’s KEV catalog.,Federal agencies must adhere to BOD 22-01 timelines to avoid compliance risks.Race conditions in validation logic can reintroduce vulnerabilities even after prior patches (e.g., CVE-2020-17136).,Cloud synchronization services introduce attack surfaces that require rigorous input validation, especially for file operations.,Time-of-check time-of-use (TOCTOU) vulnerabilities can be exploited with multi-threaded techniques to bypass security controls.,Privilege escalation via DLL side-loading remains a persistent risk when attackers can write to system directories.Incomplete patches can increase risk by creating a false sense of security.,Internet-facing WSUS servers should be strictly controlled or disabled.,Proof-of-concept (PoC) availability accelerates exploitation by opportunistic actors.,Monitoring for reconnaissance commands (e.g., PowerShell) is critical for early detection.Malvertising remains an effective initial access vector, especially when abusing trusted brands like Microsoft Teams.,Code-signing certificate abuse can bypass security controls, requiring proactive revocation by CAs.,Obfuscation techniques (e.g., packing tools) can delay AV detection, emphasizing the need for behavioral-based defenses.,RaaS models like Rhysida enable rapid scaling of attacks with varied malware (OysterLoader, Latrodectus).,Typosquatting and fake download pages exploit user trust in search engines and legitimate software.Collaboration platforms like Teams are as critical as email and equally exposed to social engineering risks.,Threat actors can exploit trust mechanisms without needing to 'break in'—they only need to 'bend trust'.,Organizations must secure not just systems but also what people believe (e.g., verification over visual trust).,Vulnerabilities in widely used tools like Teams can have cascading impacts across global enterprises.Importance of maintaining robust database security practices,Necessity of regular patching schedules for critical systems,Value of access control reviews and continuous monitoring of database activity,Urgency in addressing network-accessible vulnerabilities with high impact potentialTyposquatting remains effective for supply chain attacks despite awareness.,Obfuscation techniques (shc, encrypted C2) can evade AV detection (0/XX on VirusTotal).,GitHub Actions environment variables are high-value targets for token theft.,Short-lived malware (self-termination dates) complicates detection.,CI/CD pipelines require stricter dependency verification (e.g., package signing, allowlists).IoT devices remain a critical attack vector for large-scale DDoS botnets.,Firmware update servers (e.g., TotoLink) are high-value targets for botnet expansion.,DNS query volume rankings can be manipulated by malicious traffic, requiring proactive redaction.,Collaboration between cloud providers (Microsoft, Cloudflare) is essential for mitigating record-breaking attacks.DDoS attacks are scaling with internet infrastructure upgrades (e.g., fiber-to-home, IoT proliferation).,Botnets like Aisuru/TurboMirai pose persistent threats by exploiting unsecured IoT devices.,Cloud-native DDoS protection (e.g., Azure’s scrubbing services) is critical for mitigating large-scale attacks.,Residential ISPs are increasingly targeted as attack launchpads.Concentrated infrastructure risk (e.g., Microsoft/Amazon/Google backbones) is the biggest vulnerability, not just technology.,AI agents introduce unique risks due to autonomy and broad access, requiring non-human zero-trust models.,Identity sprawl and static authentication are no longer viable; continuous verification is essential.,Compliance can drive innovation if treated as a framework for stakeholder trust and responsible AI/data use.,The cybersecurity talent pipeline is critically thin, exacerbated by AI eliminating entry-level roles.,Optional MFA and shared responsibility models in cloud security are no longer sufficient.
Implemented Recommendations: The company has implemented the following recommendations to improve cybersecurity: Fortify critical infrastructure with network segmentation and resilience metrics., Upgrade to patched Git versions, monitor for suspicious git clone –recursive executions, audit .gitmodules file contents before cloning untrusted repositories., Treat compliance as a catalyst for innovation in data/AI governance., Consolidate IAM systems and eliminate over-permissioned roles., Invest in public-private threat intelligence sharing and cyber-resilience mandates., Adopt continuous, context-aware authentication to counter synthetic social engineering., Enforce mandatory MFA across all cloud environments., Prepare for 2026 mandates by aligning with CMMC, CIRCIA, and FISMA frameworks., Leverage insurer/investor incentives to reward verified cyber hygiene., Timely updates and patches to software, Implement zero-trust architectures for AI agents and non-human identities. and Address the talent pipeline gap by restructuring entry-level cybersecurity roles..

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.
Neuron is a PHP framework for creating and orchestrating AI Agents. In versions 2.8.11 and below, the MySQLWriteTool executes arbitrary SQL provided by the caller using PDO::prepare() + execute() without semantic restrictions. This is consistent with the name (“write tool”), but in an LLM/agent context it becomes a high-risk capability: prompt injection or indirect prompt manipulation can cause execution of destructive queries such as DROP TABLE, TRUNCATE, DELETE, ALTER, or privilege-related statements (subject to DB permissions). Deployments that expose an agent with MySQLWriteTool enabled to untrusted input and/or run the tool with a DB user that has broad privileges are impacted. This issue is fixed in version 2.8.12.
Neuron is a PHP framework for creating and orchestrating AI Agents. Versions 2.8.11 and below use MySQLSelectTool, which is vulnerable to Read-Only Bypass. MySQLSelectTool is intended to be a read-only SQL tool (e.g., for LLM agent querying, however, validation based on the first keyword (e.g., SELECT) and a forbidden-keyword list does not block file-writing constructs such as INTO OUTFILE / INTO DUMPFILE. As a result, an attacker who can influence the tool input (e.g., via prompt injection through a public agent endpoint) may write arbitrary files to the DB server if the MySQL/MariaDB account has the FILE privilege and server configuration permits writes to a useful location (e.g., a web-accessible directory). This issue is fixed in version 2.8.12.
Okta Java Management SDK facilitates interactions with the Okta management API. In versions 11.0.0 through 20.0.0, race conditions may arise from concurrent requests using the ApiClient class. This could cause a status code or response header from one request’s response to influence another request’s response. This issue is fixed in version 20.0.1.
The Auth0 Next.js SDK is a library for implementing user authentication in Next.js applications. When using versions 4.11.0 through 4.11.2 and 4.12.0, simultaneous requests on the same client may result in improper lookups in the TokenRequestCache for the request results. This issue is fixed in versions 4.11.2 and 4.12.1.
