DET0070 Detection Strategy for Phishing across platforms.

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:unifiedlogPreview.app, Safari.app, or Mail.app spawning new processes outside normal patternsDC0032 Process Creation

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
SuspiciousDomainsList of domains known for phishing activity or suspicious sender infrastructure.
ExecutionDelayWindowTime threshold between file save and execution considered suspicious.
