detecting-evasion-techniques-in-endpoint-logs
Detects defense evasion techniques used by adversaries in endpoint logs including log tampering, timestomping, process injection, and security tool disabling. Use when investigating suspicious endpoint behavior, building detection rules for evasion tactics, or conducting threat hunting for stealthy adversary activity. Activates for requests involving evasion detection, defense evasion analysis, log tampering detection, or MITRE ATT&CK TA0005.

# Detecting Evasion Techniques in Endpoint Logs
## When to Use
Use this skill when:
- Hunting for adversary defense evasion techniques (MITRE ATT&CK TA0005) in endpoint telemetry
- Building detection rules for common evasion methods (process injection, timestomping, log clearing)
- Investigating incidents where adversaries disabled or bypassed security tools
- Analyzing endpoint logs for indicators of living-off-the-land binary (LOLBin) abuse
**Do not use** this skill for network-level evasion (use network traffic analysis) or for malware reverse engineering.
## Detection Gaps & Validation
- **Direct syscalls / unhooking defeat API-based rules:** tools using direct or indirect syscalls (SysWhispers, Hell's Gate) or that unhook ntdll bypass userland EDR hooks, so CreateRemoteThread (Sysmon EID 8) may never fire. Backstop with Sysmon EID 10 (ProcessAccess to lsass, GrantedAccess `0x1010`/`0x1410`) and ETW-Ti / kernel telemetry, not just hook-based detections.
