DET0431: Detection Strategy for Email Spoofing
MITRE ATT&CK DET0431: Detection Strategy for Email Spoofing Detection Strategy details, with detection guidance, relationships and mapped CVEs.
Security context for executives and security teams
This detection strategy is tied to Email Spoofing, where adversaries may alter email sender-related headers so a message appears to come from a trusted identity. For leaders, the significance is not the email message alone; it is whether the organization can prove that inbound mail controls, SOC triage, and incident response workflows can distinguish trusted business communication from impersonation attempts before users act on them.
Executive priority
Prioritize this as an identity and business-process integrity risk. Spoofed email can undermine trust in executives, partners, suppliers, and internal workflows, so leaders should ask whether email authentication results, header evidence, and user-reported suspicious messages are available to the SOC and usable during incident response. Because the ATT&CK detection strategy object provides no official detection text, coverage should be treated as something to validate locally, not assumed.
Technical view
The supplied object is a detection strategy for T1684.002 Email Spoofing and has no official detection details or platform list of its own. Detection engineering should therefore anchor validation on the related technique: modification of relevant email headers, especially sender identity fields shown to users. SOC teams should confirm they can inspect inbound email header metadata, authentication outcomes, message routing context, and reported-message artifacts across the enterprise email environment. Tuning should focus on mismatches between displayed sender identity and underlying header/authentication evidence, while accounting for legitimate forwarding, delegated sending, mailing lists, and third-party business services.
Likely telemetry
- Inbound email headers and full message metadata
- Email authentication results and policy disposition evidence
- Mail gateway or email security platform logs
- Office suite or enterprise mailbox audit events where available
- User-reported phishing or suspicious email submissions
Detection direction
- Validate that analysts can access raw headers, not only the sender name rendered in the mail client.
- Correlate displayed sender identity with underlying header fields and authentication results before escalating or closing alerts.
- Tune for legitimate business patterns that can resemble spoofing, such as forwarding, mailing lists, delegated senders, and third-party send services.
- Test whether user-reported emails preserve enough metadata for IR review.
- Use the relationship to T1684.002 to scope detection logic around email sender impersonation and header manipulation, while avoiding claims of coverage for platforms or tactics not present on the detection strategy object itself.
Mitigation priorities
- Establish clear ownership for email authentication, inbound mail policy, SOC triage, and user reporting workflows.
- Ensure mail security and mailbox telemetry needed for header and authentication review is retained and accessible to responders.
- Create response playbooks for suspected spoofed messages, including containment, user notification, and evidence preservation.
- Regularly validate email control effectiveness using benign internal tests or tabletop exercises rather than assuming policy presence equals detection coverage.
- Document control operation and incident handling evidence for audit, compliance, and executive risk reporting.
Additional notes and limits
This ATT&CK object is sparse: it has a name, external reference, and a relationship indicating it detects T1684.002 Email Spoofing, but no official description, detection text, tactics, or platforms of its own. The practical guidance above is derived from the relationship context describing spoofed sender identity via email headers and from the related technique’s listed enterprise platforms.
No official detection logic, data sources, mitigations, or procedure examples were supplied for DET0431. Local email architecture, authentication configuration, logging retention, and SOC workflow evidence are required to determine actual coverage.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.
