ConsentFix and ClickFix: How Microsoft 365 Accounts are Hijacked in 3 Seconds
ConsentFix and ClickFix attacks steal Microsoft 365 tokens via fake prompts and OAuth flows.
ConsentFix and ClickFix are new attack techniques that hijack Microsoft 365 accounts by stealing OAuth tokens in seconds. ClickFix tricks users into executing commands via fake prompts, while ConsentFix exploits OAuth consent flows by having users drag a localhost callback link into their browser, unknowingly surrendering session tokens. These methods bypass traditional security awareness training and MFA, with detailed attack blueprints being shared openly on cybercrime forums.

The lesson from this incident
Full lessonConsentFix and ClickFix represent a new generation of social engineering attacks that exploit OAuth consent flows and user-executed commands to steal session tokens, effectively rendering MFA irrelevant once a token is surrendered. The root problem is that users are manipulated into voluntarily granting access — through drag-and-drop UI tricks or fake browser prompts — meaning no credential is ever stolen in the traditional sense. Organizations relying solely on MFA and standard security awareness training have a dangerous blind spot here, as these attacks operate entirely within legitimate authentication flows. The open sharing of detailed attack blueprints on cybercrime forums means threat actor skill barriers are extremely low, dramatically increasing the likelihood of widespread exploitation.
What helps against this
How we list vendors- Phishing-resistant MFA
A stolen password, or a user who taps Approve on a push prompt, is no longer enough to log in.
- Identity threat detection and response (ITDR)
Attackers who log in with real, stolen credentials get noticed.
- Email security
Phishing, malware and invoice fraud are filtered out before they reach inboxes.
