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.

Prerequisites

• Sysmon installed and configured with comprehensive logging rules (SwiftOnSecurity or Olaf Hartong config)
• Windows Security Event Log with advanced audit policy enabled
• EDR telemetry (CrowdStrike, SentinelOne, Microsoft Defender for Endpoint)
• SIEM platform for log correlation (Splunk, Elastic, Sentinel)
• MITRE ATT&CK Enterprise matrix for technique reference

Workflow

Step 1: Detect Log Tampering (T1070)

Windows Event Log clearing (T1070.001):

# Sysmon Event ID 1 (Process Create) for wevtutil
EventID: 1
CommandLine contains: "wevtutil cl" OR "wevtutil clear-log"

# Security Event …
