Poll-based host intrusion-detection daemon modeled on freeze-watcher's sample→trigger→snapshot→classify loop, with security signatures instead of performance ones: - reverse_shell (interpreter with a network socket on stdio) - ld_preload (/etc/ld.so.preload or LD_PRELOAD in writable dirs) - deleted_exe (process running from a deleted/memfd binary) - new_listener (listening port absent from startup baseline) - new_suid (new SUID/SGID binary; critical in writable dirs) - persistence (cron/systemd/authorized_keys/rc-file changes) - suspicious_egress (interpreter holding an outbound public connection) Each capture writes a forensic snapshot with per-signature incident- response guidance. Includes a safe, self-cleaning red-team harness (sentinel-redteam), hardened systemd unit, config, Makefile, and Arch packaging. Tested on Arch: detectors fire on drills, no false positives on a clean sweep, sweep cost optimized from ~15s to ~1s via batched syscalls and a gated filesystem-wide SUID scan. This bash implementation is retained as the regression oracle for the forthcoming Python rewrite. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
