DET0058 Detection Strategy for Web Service: Dead Drop Resolver

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
TargetDomainDead drop hosting domain (e.g., GitHub, Google Docs)
PayloadEntropyThresholdDetects high entropy in payloads signaling obfuscation
TimeWindowCausal proximity between access to resolver and follow-up connections
