Privilege Abuse

This note documents detection patterns related to Privilege Abuse within Windows environments.


Direct Indicators

LogEvent IDMeaningForensic ValueNotes
Security4672Special privileges assigned to new logonCriticalCore indicator that sensitive privileges were granted at logon.
Security4673Sensitive privilege use attemptedCriticalDetects use of powerful privileges such as SeDebugPrivilege.
Security4674Privileged object operationCriticalHigh-value event when attacker abuses token privileges against protected objects.
Security4688Process creationCriticalDetect commands using token abuse, privilege-sensitive tools, or elevated shells.
Sysmon1Process creationCriticalBest execution source for privilege abuse tooling.
Sysmon10Process accessCriticalStrong signal when attacker opens LSASS or protected processes.
Security4624Successful logonHighLogon context before privilege abuse.
Security4648Explicit credentials usedHighUseful when alternate credentials precede privilege abuse.

Indirect Indicators

IndicatorWhat To Look ForForensic ValueNotes
SeDebugPrivilege abuseAccess to LSASS / SYSTEM processesCriticalCommon escalation path.
Token duplicationProcess impersonation or SYSTEM child creationCriticalIndicates token theft or impersonation.
Elevated shell from medium parentUser shell unexpectedly spawns SYSTEM processHighSuspicious token transition.
Privilege-sensitive tool executionPsExec, Mimikatz, ProcDumpCriticalStrong offensive signal.
Access denied followed by successRetry after elevationHighSuggests privilege escalation chain.
Unusual service restart after privilege useService manipulated after elevationHighOften follows SeTakeOwnershipPrivilege abuse.

Common Tools

ToolUsage
whoami.exeCheck enabled privileges
mimikatzToken abuse, privilege enablement
PsExecSYSTEM execution
procdump.exeProtected process dump
PowerShellToken manipulation / privilege testing
accesschk.exePrivilege enumeration
Process HackerToken inspection
rundll32.exeAbuse privileged DLL execution

  • T1003 Credential Dumping

Decision Tree

  1. Was sensitive privilege granted?

    • Check 4672
    • Identify account
  2. Was privilege actively used?

    • Check 4673 / 4674
  3. Which process used it?

    • Parent-child lineage
    • Integrity level
  4. Was protected process accessed?

    • LSASS
    • SYSTEM service
  5. Expand:

    • Token duplication
    • Credential access
    • Persistence after elevation
  6. Scope:

    • Single host
    • Lateral movement
    • Domain privilege path
