<p>Adversaries attempt to read sensitive files such as /etc/passwd and /etc/shadow for credential dumping. This may involve access to the files directly via command-line utilities (e.g., cat, less), creation of backup copies, or parsing through post-exploitation frameworks. Multi-event correlation includes elevated process execution, file access/read on sensitive paths, and anomalous read behaviors tied to non-root or unusual users.</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
exeExecutable name used to access credentials (e.g., cat, cp, awk); can vary across environments
userUser context under which the access occurs; typically root, but can be non-standard in attacks
PATHTarget file paths (e.g., /etc/passwd, /etc/shadow); may vary in containerized or customized systems
TimeWindowTime correlation threshold for chaining access and execution events
