TL;DR: Higher education inboxes are now being hit by business email compromise, account takeovers, vendor fraud, and AI-generated phishing that are more precise, scalable, and harder to detect with traditional controls, according to Abnormal AI. The governing issue is no longer just email filtering but identity-aware defense across faculty, staff, students, and third parties.
NHIMG editorial — here’s why we think this discussion matters
Questions worth separating out
Q: How should universities reduce the risk of business email compromise across campus accounts?
A: Universities should combine mailbox monitoring with identity governance, because BEC usually succeeds when a trusted account is used in a normal workflow.
Q: Why do higher education environments face more email fraud risk than many enterprises?
A: Higher education has a distributed trust model with many identities, many external relationships, and inconsistent verification habits.
Practitioner guidance
- Segment email governance by identity class Separate policy for faculty, staff, students, researchers, and vendors so risk scoring reflects the different trust relationships and access expectations in each group.
- Correlate mailbox risk with identity signals Feed account status, privilege changes, anomalous sign-in behaviour, and external sender patterns into one review path so investigators can see abuse across the identity layer.
- Test defences against AI-generated phishing Run simulations that use convincing, context-aware lures instead of obvious phishing templates, then measure whether detections and reporting improve under realistic conditions.
What to expect at the briefing
Abnormal AI's full webinar covers the operational detail this post intentionally leaves for the source:
- The live discussion of Lehigh University incident lessons and how the campus team handled real-world email threats.
- Practical examples of how security leaders distinguish business email compromise from account takeover and vendor fraud.
- A deeper look at the operational realities of defending faculty, staff, and student mail flows in a large distributed environment.
- The on-demand session's fuller breakdown of where legacy email controls fall short and what behavioural detection changes.

Email abuse in higher education is an identity governance problem, not just a messaging problem. The article describes business email compromise, account takeover, vendor fraud, and AI-generated phishing as overlapping threats, which is exactly how modern identity abuse behaves. Once email becomes the entry point for financial redirection, impersonation, or trust abuse, the control plane has moved beyond content filtering and into identity assurance, mailbox governance, and privilege validation. Practitioners should treat campus email as part of the identity stack, not a separate security silo.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities.
A question worth separating out:
Q: How can organisations improve verification for sensitive email-driven requests?
A: Use out-of-band verification for payment changes, account recovery, routing changes, and unusual vendor requests. The key is to validate the request through a separate trusted channel before acting on it. That reduces the chance that a compromised mailbox can be used to redirect money or approvals.
