TL;DR: AI-powered phishing, trusted-platform abuse, and cross-channel conversation shifting are undermining legacy email defenses, according to Abnormal AI’s on-demand webinar preview. The core issue is that inbox security still assumes static patterns and single-channel detection, while modern attackers now personalise, pivot, and persist across the collaboration stack.
Editorial analysis by NHI Mgmt Group, based on content published by Abnormal AI: “How Threat Actors Are Weaponizing AI and Trust in 2025”.
Key questions
Q: How should security teams defend against AI-personalised phishing in email?
A: They should combine content inspection with behavioural and identity signals, because AI-personalised phishing is designed to look relevant, timely, and low-risk.
Q: Why do trusted collaboration platforms make email attacks harder to stop?
A: Trusted collaboration platforms make attacks harder to stop because users often extend platform trust to the content delivered through them.
Practitioner guidance
- Harden cross-channel detection Correlate email, chat, and file-sharing activity so suspicious conversation shifts are visible as one interaction chain rather than isolated events.
- Verify trusted-platform provenance Inspect links, shared files, and invitations from familiar collaboration services before users are allowed to act on them, especially when the request changes channel mid-thread.
- Tune controls for AI-personalised lures Update detection logic to weight behavioural context, relationship patterns, and timing anomalies instead of relying mainly on content signatures.
Bottom line: AI-personalised email attacks bypass legacy inbox controls because they exploit context, trust, and channel continuity rather than obvious malicious indicators.

AI-driven email fraud is really a trust-engineering problem, not an inbox hygiene problem. Legacy controls were built to score messages, but the article describes attacks that now shape context, timing, and channel choice around the victim. That means the decisive failure is not only malicious content detection, but the inability to verify whether the communication path itself still deserves trust. Practitioners should treat message trust as a sequence, not a single verdict.
A question worth separating out:
Q: How can email security fit into identity governance more effectively?
A: Email security should feed identity-aware response, not sit apart from it. If a suspicious message leads to credential theft, mailbox abuse, or account takeover, the control value lies in how quickly the organisation can investigate, contain, and review access. That makes integration with identity workflows as important as detection quality.
