Open-source DFIR Velociraptor was abused in expanding ransomware efforts
Attribution and the ransomware cocktail: Talos links the campaign to Storm-2603, a suspected China-based threat actor, citing matching TTPs like the use of ‘cmd.exe’, disabling Defender protections, creating scheduled tasks, and manipulating Group Policy Objects. The use of multiple ransomware strains in a single operation Warlock, LockBit, and Babuk also bolstered confidence in this attribution.”Talos…

PoC Released for Linux Kernel ksmbd Filesystem Vulnerability
Security researcher Norbert Szetei published the final installment of his deep-dive into the ksmbd filesystem module, culminating in a working proof-of-concept exploit targeting CVE-2025-37947. Unlike earlier use-after-free candidates that required complex race conditions or depended on external factors, this vulnerability offers a deterministic out-of-bounds (OOB) write primitive. Szetei’s PoC was tested on Ubuntu 22.04.5 LTS…
