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.

Log sourceChannelData component
macos:unifiedlogsubsystem: com.apple.networkDC0085 Network Traffic 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.

FieldDescription
TargetServiceKnown services abused for D2 (e.g., iCloud, Dropbox)
UserContextUseful to isolate rare users accessing web services for C2
TimeWindowMax time gap between dead drop resolver fetch and follow-on traffic
