ATT&CK analytic guidance
DET0431 Detection Strategy for Email Spoofing
AN1202 Analytic 1202
Monitor email message traces and headers for failed SPF, DKIM, or DMARC checks indicating spoofed sender identities. Correlate abnormal sender domains or mismatched return-paths with elevated spoofing likelihood.
AN1203 Analytic 1203
Detects spoofed emails by analyzing mail server logs (e.g., Postfix, Sendmail) for mismatched header fields, failed SPF/DKIM checks, and anomalies in SMTP proxy logs. Defender observes discrepancies between sending domain, return-path domain, and message metadata.
AN1204 Analytic 1204
Detects suspicious inbound mail traffic where SPF/DKIM/DMARC authentication fails or where sender and return-path domains mismatch, observable in Apple Mail unified logs or MDM-controlled logging pipelines.
AN1205 Analytic 1205
Correlates Office 365 or Google Workspace audit logs for spoofed sender addresses, failed email authentication, and anomalies in message delivery metadata. Defender observes failed SPF/DKIM checks and domain mismatches tied to suspicious campaigns.
