Persistent OAuth tokens — an invisible "backdoor" bypassing MFA

Colleagues, a cybersecurity alert: persistent OAuth grants are a real vulnerability.

In brief:
- Material Security: many organizations don’t monitor OAuth tokens — they don’t expire, aren’t revoked on password change and aren’t visible at the perimeter.
- Drift incident: stolen refresh tokens from a legitimate integration let an attacker access hundreds of customers, bypassing MFA.
- What to do: continuous app-behavior monitoring, blast-radius assessment and tiered response (automated remediation for clear threats).

Why it matters: the surge in AI integrations increases exposure and makes grants an attractive attack vector.

How do you monitor OAuth grants in your organization?
