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.

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.

FieldDescription
WatchedBinariesList of critical security daemons (e.g., auditd, falco, AV agents) to monitor for exploitation.
CrashPatternsRegex or patterns for kernel/syslog errors correlated with exploitation attempts.
