Hunting rule loosely modeled after Atomic Red Team T1112 test "Disable Windows LogOff Button". Correlate before alerting on.
Hunting rule loosely modeled after Atomic Red Team T1112 test "Modify Registry of Current User Profile - cmd". No public in-the-wild intel reference available; correlate before alerting.
Hunting rule loosely modeled after Atomic Red Team T1112 test "Disable Windows LogOff Button". Correlate before alerting on.
Hunting rule loosely modeled after Atomic Red Team T1112 test "Disable Windows Task Manager application". No public in-the-wild intel reference available; correlate before alerting.
Hunting rule based off of T1112 technique "Modify Registry of Local Machine - cmd". No public in-the-wild intel reference available; correlate before alerting.
Detects BPFDoor-style iptables NAT REDIRECT rules used to tunnel traffic from a
legitimate service port to a high ephemeral shell port (42391-43390) without
disrupting the real service for other clients. BPFDoor activates on magic packets, spawns a
bind shell, inserts short-lived PREROUTING redirects for the controller IP, then deletes them.

Detects fileless Linux malware execution patterns that run payloads from anonymous memory files (memfd_create) or inherited file descriptors under /proc/self/fd without touching disk. Used by Linux backdoors and miners to evade filesystem-based detection.
Hunting rule for nmap used for internal network discovery.
Legitimate vulnerability management and pentests also run nmap; prioritize hits when the source is a server or workload not in your scanner inventory, the parent is an interactive shell or script dropped, or the event chains with
tunneling (chisel, proxychains), or lateral movement.
Strongest signals: RFC1918 subnet sweeps, -iL target lists, proxychains-wrapped
-sT/-Pn scans, and full-port sweeps across private ranges.

Detects the execution of certutil.exe with command-line flag that can be used to interact with Active Directory Certificate Services, potentially for malicious purposes such as certificate theft or abuse.
