Description: The rise of clandestine 'travel agencies' on darknet forums has led to significant financial losses for travel and hospitality industries. These agencies sell fraudulently booked flights, hotels, and other services at discounted rates, starting with credential theft and ending with fraudulent bookings. Airlines lose seat inventory, hotels absorb charge-backs, and travelers face drained reward balances. Trustwave reported one agency processed over 2,000 bookings in Q1 2025, netting $1.4 million in illicit revenue.
Description: The **ClickFix phishing campaign** targeted **Booking.com** and its affiliated hotels by exploiting compromised accounts to distribute **PureRAT malware** via phishing emails and WhatsApp messages. Attackers purchased stolen **Booking.com administrator credentials** from dark web forums (e.g., LolzTeam) to craft convincing scams. Victims—both hotels and guests—were lured into fake **Booking/Expedia login pages**, where their **login credentials and payment card data** were harvested. The malware (**PureRAT**) enabled remote access, keystroke logging, and surveillance via webcam/microphone, allowing attackers to map hotel customer databases for further fraud. Fraudulent wire transactions were also executed using stolen data. The campaign, active since at least **April 2025**, leveraged real reservation details to enhance credibility, amplifying financial and reputational damage. While the exact scale of compromise remains undisclosed, the attack disrupted trust in Booking.com’s platform, exposed sensitive customer financial data, and enabled downstream fraud against hotels and guests.
Description: A large-scale phishing campaign orchestrated by Russian threat actors has targeted **Booking.com** since February, involving the registration of over **4,300 fraudulent domains** mimicking legitimate booking and rental platforms like Expedia and Agoda. The attack specifically aimed to deceive hotel guests into divulging their **payment details**, including credit card information, bank account credentials, and personal identification data. By impersonating trusted booking services, the threat actors exploited user trust to harvest sensitive financial information, leading to potential **fraudulent transactions, identity theft, and financial losses** for affected customers. The scale of the operation suggests a systematic effort to compromise a high volume of users, leveraging social engineering tactics to bypass traditional security measures. While the exact number of victims remains undisclosed, the prolonged duration of the campaign (since February) indicates a sustained and evolving threat, with potential long-term reputational damage to Booking.com due to eroded customer confidence in its platform’s security.

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.
