<p>Detects abnormal interaction with memory-based Kerberos ccache (API:{uuid}) or file-based overrides. Focus on processes attempting to enumerate or extract Kerberos tickets outside of built-in utilities. Detects use of open-source tools (e.g., Bifrost, modified Mimikatz ports) that interact with the Kerberos framework APIs.</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.
