DaVita Inc.
Breach
Rankiteo Explanation
Attack without any consequences
Description: On **June 17, 2024**, DaVita Inc. suffered a **data breach** involving unauthorized transmission of personal information via **online tracking technologies** to third-party vendors. The exposed data included **IP addresses, usernames, and demographic details**, but **no highly sensitive information** such as Social Security numbers, financial account details, or medical records was compromised. The incident was disclosed by the **California Office of the Attorney General** on **July 3, 2024**. The breach primarily affected **non-critical personal data**, meaning the impact was limited to **potential privacy concerns** rather than financial fraud or identity theft. While the exposure of IP addresses and usernames could lead to **targeted phishing attempts** or **reputational harm**, there was no evidence of malicious exploitation of the leaked data. The company likely faced **regulatory scrutiny** under data protection laws (e.g., CCPA) but avoided severe operational or financial disruptions. No ransomware, direct cyberattack, or systemic vulnerability exploitation was reported in this case.
DaVita Kidney Care
Breach
Rankiteo Explanation
Attack with significant impact with customers data leaks
Description: DaVita Inc. experienced a data breach after an unauthorized party accessed sensitive consumer data entrusted to the company. The breach compromised the names, addresses, Social Security numbers, medical information and health insurance information of certain individuals including 1,072 Texas residents.
DaVita
Ransomware
Rankiteo Explanation
Attack threatening the organization's existence
Description: DaVita, a Fortune 500 company specializing in kidney care, experienced a significant data breach resulting in the theft and leak of 1.5 terabytes of data from their systems. The attack was carried out by the Interlock ransomware group, which has been actively targeting businesses and critical infrastructure organizations with double extortion attacks. The stolen data included sensitive information, impacting the company's operations and potentially compromising patient data.
DaVita Healthcare
Ransomware
Rankiteo Explanation
Attack threatening the organization’s existence
Description: Interlock ransomware group targeted DaVita Healthcare, a major healthcare provider specializing in kidney dialysis treatment. In April 2025, the group stole a staggering 20 terabytes (TB) of sensitive patient data. This attack highlights a significant shift in targets for the Interlock ransomware group, which is known for its double-extortion tactics. The theft of such a large amount of sensitive data raises concerns about the security of healthcare information and the potential for further attacks on critical sectors.
DaVita
Ransomware
Rankiteo Explanation
Attack that could injure or kill people
Description: DaVita, a major U.S. dialysis service provider operating nearly 3,000 outpatient clinics and serving ~200,000 patients annually, suffered a **ransomware attack** that encrypted parts of its IT network. The incident, discovered on **Saturday**, caused **operational disruptions**, forcing the company to isolate affected systems while continuing patient care. DaVita could not estimate the **duration or full extent** of the disruption, which impacted its ability to restore critical functions. The attack follows a broader trend of cyber threats in healthcare, including a 2023 breach at rival **Fresenius Medical Care** (500,000 patient records stolen) and a 2023 ransomware attack on **UnitedHealth Group’s tech unit** (100 million records exposed). DaVita engaged third-party cybersecurity experts and notified law enforcement. Given its role in life-sustaining dialysis services, the attack poses risks to **patient safety** and **operational continuity**, with potential cascading effects on healthcare delivery.
DaVita
Ransomware
Rankiteo Explanation
Attack threatening the organization's existence
Description: DaVita, a leading US-based kidney dialysis provider, suffered a severe ransomware attack in **March 2025**, orchestrated by the **Interlock** gang. The breach compromised **2,689,826 patient records**, with hackers allegedly exfiltrating **1.51 TB of sensitive data**, including medical histories, treatment details, and personally identifiable information (PII). The attack disrupted critical healthcare operations, raising concerns over patient safety and data privacy compliance (e.g., HIPAA violations). While DaVita did not confirm whether a ransom was paid, the incident underscored vulnerabilities in third-party vendor integrations and legacy system protections. The breach’s scale—ranked among the **top 5 largest healthcare ransomware attacks of Q1-Q3 2025**—highlighted the escalating targeting of healthcare providers by cybercriminals exploiting high-value patient data for extortion. The prolonged recovery period further strained resources, with potential long-term reputational damage and regulatory penalties looming.
DaVita
Ransomware
Rankiteo Explanation
Attack that could injure or kill people
Description: DaVita, a US-based kidney dialysis firm operating over 2,600 treatment centers across 12 countries, suffered a ransomware attack on April 12, 2025. The attack encrypted critical systems, disrupting operations and forcing the company to isolate affected networks. While DaVita activated response protocols and restored some functions via contingency plans to maintain patient care, the full scope of the breach—including potential data exfiltration—remains unknown. The incident impacted core operations, with no estimated timeline for full recovery. No ransomware group has claimed responsibility, and the attacker’s identity is still under investigation. Given the nature of the attack and the company’s role in life-sustaining medical services, the disruption poses significant risks to patient treatment continuity, though no direct harm to individuals has been confirmed yet. The company is collaborating with cybersecurity experts and law enforcement to assess and mitigate the damage.

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.

Description
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.

Description
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).
