Booking.comCyber Attack6026/2025
Rankiteo Explanation :
Attack limited on finance or reputation

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.

Booking.comCyber Attack8544/2025
Rankiteo Explanation :
Attack with significant impact with customers data leaks

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.

Booking.comCyber Attack8542/2025
Rankiteo Explanation :
Attack with significant impact with customers data leaks

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.

Latest Global CVEs (Not Company-Specific)

Description

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.

Description

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Uncontrolled Recursion vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs. This issue has been patched in version 1.3.2.

Description

Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. An Integer Overflow vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions. This issue has been patched in version 1.3.2.

Description

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, working with large buffers in Lua scripts can lead to a stack overflow. Users of Lua rules and output scripts may be affected when working with large buffers. This includes a rule passing a large buffer to a Lua script. This issue has been patched in versions 7.0.13 and 8.0.2. A workaround for this issue involves disabling Lua rules and output scripts, or making sure limits, such as stream.depth.reassembly and HTTP response body limits (response-body-limit), are set to less than half the stack size.

Description

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.
