Cobalt Strike Beacon Injection via ProcessAccess and CreateRemoteThread into Common Host Processes
Detects potential Cobalt Strike Beacon process injection activity by monitoring Sysmon events for suspicious cross-process access (EID 10) and remote thread creation (EID 8). The rule specifically targets high-value host processes (svchost.exe, explorer.exe, rundll32.exe, notepad.exe) and filters common legitimate behaviors such as antivirus memory scanning and JIT compilation to reduce false positives.
