Linux · attack.mitre.org · ATT&CK Enterprise v19.2
<p>Detects kernel- or user-space exploitation attempts targeting auditd, AV daemons, or security monitoring agents. Defender observation includes unexpected segfaults, privilege escalation attempts from low-privileged processes, or modifications to security binaries. Correlates exploitation attempts with subsequent gaps in logging or terminated processes.</p>

Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| auditd:SYSCALL | execve: Execution of suspicious exploit binaries targeting security daemons | DC0032 Process Creation |
| linux:syslog | Segfaults, kernel oops, or crashes in security software processes | DC0038 Application Log Content |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
WatchedBinaries | List of critical security daemons (e.g., auditd, falco, AV agents) to monitor for exploitation. |
CrashPatterns | Regex or patterns for kernel/syslog errors correlated with exploitation attempts. |
