TL;DR: Modern phishing and BEC increasingly exploit identities, relationships, and context rather than malicious payloads, and static training or rule-based controls are no longer enough, according to Abnormal AI. The governing problem is that email security now depends on correlating identity risk across collaboration systems, OAuth apps, and user behavior, not on filtering messages alone.
Editorial analysis by NHI Mgmt Group, based on content published by Abnormal AI: “2026 Email Security Checklist: New Year, New Inbox Problems”.
Key questions
A: Security teams should treat identity theft as a control problem, not just a user-awareness problem.
Q: Why do compromised identities matter so much in email security?
A: Because a trusted account can move from email into collaboration tools, SaaS apps, and financial workflows without triggering the same suspicion as an external attacker.
Q: What are the signs that email threat controls are missing lateral phishing and internal abuse?
A: Common signs include suspicious messages sent from legitimate internal addresses, unexpected forwarding rules, abnormal file access after sign-in, and reports of mail that looks normal at first but becomes suspicious in sequence with other account activity.
Practitioner guidance
- Map email controls to identity risk signals Correlate login behaviour, session changes, collaboration activity, and delegated access so email alerts are evaluated in identity context rather than in isolation.
- Review OAuth and mailbox permissions continuously Flag risky OAuth grants, excessive mailbox delegation, legacy authentication, and insecure connectors as part of the same posture review cycle.
- Automate abuse-mailbox triage Use classification, clustering, and enrichment to turn user-reported messages into actionable detections instead of manual queue work.
Bottom line: Modern email compromise succeeds by abusing trusted identities, not just by delivering malicious content.

Email security has become an identity governance problem, not a content-filtering problem. The article shows that attackers increasingly win by abusing trust relationships, account state, and collaboration context rather than malicious payloads. That shifts the control point from message inspection to identity posture, because the dangerous event is often trusted access being used in an untrusted way. Practitioners should treat email as a governed identity surface, not just a detection channel.
A few things that frame the scale:
- 73% of vaults are misconfigured, leading to unauthorised access and exposure of sensitive data, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations treat phishing awareness as a control or an influence factor?
A: It should be treated as a supporting control, not the primary defence. Static awareness training has limited impact against AI-driven, context-aware fraud, so organisations need adaptive simulations, telemetry-backed measurement, and technical detection that can validate whether users and systems are actually changing behaviour.
