Linux Furtex Toolkit Enables Stealthy Process Injection and Data Exfiltration

Furtex is a newly disclosed Linux post-exploitation and evasion framework built around raw io_uring and eBPF operations that packages stealthy file/network access, process injection, BPF map/program manipulation, and telemetry suppression; the release is presented as a research/red-team toolkit but signals growing offensive use of legitimate kernel features and warns defenders to monitor unexpected io_uring and BPF activity, raw sockets, and audit suppression.
