TL;DR: Columbia University’s 2025 breach exposed 1.6 gigabytes of sensitive data from 2.5 million student applications, underscoring how weak identity verification, legacy MFA, and inherited vendor trust continue to make universities attractive targets, according to 1Kosmos. Identity-first security now matters because campus risk is being driven by who can authenticate, not just which systems can be reached.
Editorial analysis by NHI Mgmt Group, based on content published by 1Kosmos: “Columbia University hack exposes the identity crisis in higher education”.
By the numbers:
- Attacks targeting universities have surged nearly 70% since 2023.
- Institutions are now facing an average of over 2,500 cyberattack attempts each week.
Key questions
Q: What breaks when help desk identity verification is too easy to bypass?
A: When verification is weak, attackers can impersonate legitimate users or internal staff and push through password resets, MFA changes, or access reinstatement.
Q: Why do universities remain attractive targets even when they already use MFA?
A: Universities remain attractive because many deployments still rely on MFA that can be phished, fatigued or socially engineered around.
Q: What are the signs that campus identity governance is failing?
A: Common warning signs include shared logins, delayed offboarding, role overlap that accumulates entitlements, and departments managing access differently from central identity teams.
Practitioner guidance
- Strengthen identity proofing for recovery workflows Require stronger verification for password resets, account unlocks and help desk escalations so attackers cannot turn support processes into access issuance paths.
- Replace phishable MFA with phishing-resistant authentication Move high-risk campus populations to authentication that cannot be replayed or coerced through simple social engineering, especially for remote and mobile users.
- Map third-party access to explicit offboarding triggers Tie every vendor account and integration to a named owner, a review cadence and a revocation step when the relationship or service scope changes.
Bottom line: Columbia’s breach shows that higher education identity gaps can convert routine support and authentication processes into breach paths.

Campus identity governance is now the primary control plane for higher education risk. Universities no longer fail only at the network edge or endpoint. They fail when identity proofing, authentication and recovery workflows cannot resist social engineering at scale, which makes the identity layer the real boundary of control.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: How should universities govern third-party access after a vendor relationship changes?
A: Universities should treat third-party access as time-bound and revocable, with a named owner, review cadence and offboarding trigger for every integration and support account. If access persists after a relationship changes, it becomes inherited trust rather than controlled access. That is where many campus exposures widen unnecessarily.
