29 minutes. Wrong problem.

Per BleepingComputer, Microsoft Entra ID is shifting to passkeys as the default authentication method starting September 2026, as announced by Microsoft Security Blog. However, The Hacker News reports that at least two threat actors are exploiting an OAuth client ID spoofing technique to validate stolen Microsoft Entra credentials without triggering sign-in events.

The conventional reading misses that this is not a passkey problem, but an identity perimeter failure. According to the Microsoft Security Blog, passkeys will enhance security, yet the real issue lies in the ability of attackers to slip past telemetry. While Microsoft Entra ID gets a security boost with passkeys, the OAuth client ID spoofing technique exposes a deeper flaw, as noted by The Hacker News.

The defensive math: -> Implement passkey authentication, as Microsoft Entra ID will have it as default, to reduce reliance on weaker methods -> Review and strengthen OAuth client ID management, as advised by Microsoft Security Blog, to prevent spoofing -> Monitor for unusual account activity, as The Hacker News warns of stealthy validation of stolen credentials, and adjust telemetry to detect such evasion techniques

What will you do to prevent OAuth client ID spoofing in your organization before September 2026?
