TL;DR: A single phishing email can now compromise entire education networks by abusing trusted platforms such as Google Forms and Microsoft SharePoint, while AI-written lures, trusted-sender abuse, and OTP relay accelerate lateral phishing across cloud environments, according to Abnormal AI. Trusted communication channels have become an identity problem, not just an email problem.
Editorial analysis by NHI Mgmt Group, based on content published by Abnormal AI: “Phishing 2.0: Duo Passcodes Under Siege in Higher Education”.
Key questions
Q: What fails when phishing uses trusted collaboration tools instead of obvious malicious links?
A: The failure is a trust model that treats collaboration tools as safe by default.
Q: Why does OTP relay increase account takeover risk in education environments?
A: OTP relay works because the attacker uses a valid code before the authentication moment expires.
Practitioner guidance
- Map trusted collaboration channels to identity risk Catalogue which forms, file-sharing spaces, and messaging paths can initiate or amplify authentication events, and treat them as part of the phishing attack surface.
- Harden OTP and recovery workflows Reduce the value of real-time code relay by tightening session binding, device checks, and help-desk recovery paths that attackers can abuse after the lure lands.
- Detect lateral phishing behaviour inside cloud suites Monitor for unusual internal sends, rapid message forwarding, and account-to-account trust abuse across Microsoft 365 and Google Workspace.
Bottom line: The article shows that trusted tools in education can be turned into phishing infrastructure, so the risk is now distributed across email, collaboration and identity flows.

Trusted-channel phishing is now an identity governance problem, not a mail-filter problem. When attackers weaponise Google Forms, Microsoft SharePoint and trusted-sender paths, the control boundary moves from message inspection to trust lifecycle governance. Education institutions that still treat collaboration tools as separate from identity policy are protecting the wrong layer. The practitioner implication is to govern trust paths end to end, not inbox by inbox.
A few things that frame the scale:
- Roughly 1 in 3 phishing payloads are delivered outside email, through channels such as social media, search ads and messaging apps.
A question worth separating out:
A: They should constrain the trust extensions that let one account become a relay for more compromise. That means reviewing delegated access, mailbox rules, shared collaboration spaces and recovery workflows together, because attackers exploit the connections between them rather than one control in isolation.
