The digital economy runs on Open Source Software (OSS), with an estimated 90\% of modern applications containing open-source components. While this widespread adoption has revolutionized software development, it has also created critical security vulnerabilities, particularly in essential but under-resourced projects. This paper examines a sophisticated attack on the XZ Utils project (CVE-2024-3094), where attackers exploited not just code, but the entire open-source development process to inject a backdoor into a fundamental Linux compression library. Our analysis reveals a new breed of supply chain attack that manipulates software engineering practices themselves -- from community management to CI/CD configurations -- to establish legitimacy and maintain long-term control. Through a comprehensive examination of GitHub events and development artifacts, we reconstruct the attack timeline, analyze the evolution of attacker tactics. Our findings demonstrate how attackers leveraged seemingly beneficial contributions to project infrastructure and maintenance to bypass traditional security measures. This work extends beyond traditional security analysis by examining how software engineering practices themselves can be weaponized, offering insights for protecting the open-source ecosystem.

Numerous law enforcement agencies worldwide have been affected by a zero-day exploit (path traversal) in reconnaissance software. This apparently also includes body cameras used by special forces, surveillance equipment, and police drones.

The „Media Relay Service (MRS)“ (web server) software for reconnaissance devices from the Israeli manufacturer Infodraw is affected by a serious security vulnerability (Path Traversal Vulnerability). Security experts from Mint Secure discovered the vulnerability and initially reported it to the manufacturer and – due to a lack of response – subsequently to operators and CERTs worldwide in order to rule out further risks and responsibly disclose the vulnerability. This blog post describes technical details, cases from various countries, and the approach behind the discovery. Recommendations for affected organizations are also provided.

• CVE-2025-24054 is a vulnerability related to NTLM hash disclosure via spoofing, which can be exploited using a maliciously crafted .library-ms file. Active exploitation in the wild has been observed since March 19, 2025, potentially allowing attackers to leak NTLM hashes or user passwords and compromise systems. Although Microsoft released a patch on March 11, 2025, threat actors already had over a week to develop and deploy exploits before the vulnerability began to be actively abused.

• Around March 20–21, 2025, a campaign targeted government and private institutions in Poland and Romania. Attackers used malspam to distribute a Dropbox link containing an archive that exploited multiple known vulnerabilities, including CVE-2025-24054, to harvest NTLMv2-SSP hashes.

  • Initial reports suggested that exploitation occurred once the .library-ms file was unzipped. However, Microsoft’s patch documentation indicated that the vulnerability could even be triggered with minimal user interaction, such as right-clicking, dragging and dropping, or simply navigating to the folder containing the malicious file. This exploit appears to be a variant of a previously patched vulnerability, CVE-2024-43451, as both share several similarities.

(2) For the second year till, and including, the fifth year from the End of Life, Yealink will attempt to provide SW bug fixes. In the EOL support phase, a SW upgrade of the product to a newer existing release will also be seen as a fix to the SW bug. Providing a fix may not be possible in some cases due to the limitation of hardware or software architecture, and Yealink in its sole discretion will determine what fixes, if any, will be provided.

(3) Yealink will not offer any New Features/Enhancements support from the End of Life.

(4) Spares or replacement parts for hardware will be available depending on your local distributors.

-------------------------
- The default dictionary size values for LZMA/LZMA2 compression methods were increased:
         dictionary size   compression level
  v24.08  v24.09  v24.09
          32-bit  64-bit
    8 MB   16 MB   16 MB   -mx4
   16 MB   32 MB   32 MB   -mx5 : Normal
   32 MB   64 MB   64 MB   -mx6
   32 MB   64 MB  128 MB   -mx7 : Maximum
   64 MB   64 MB  256 MB   -mx8
   64 MB   64 MB  256 MB   -mx9 : Ultra
  The default dictionary size values for 32-bit versions of LZMA/LZMA2 don't exceed 64 MB.
- 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.
- APM and HFS support was improved.
- If an archive update operation uses a temporary archive folder and
  the archive is moved to the destination folder, 7-Zip shows the progress of moving
  the archive file, as this operation can take a long time if the archive is large.
- The bug was fixed: 7-Zip File Manager didn't propagate Zone.Identifier stream
  for extracted files from nested archives (if there is open archive inside another open archive).
- Some bugs were fixed.
