Attackers abused stolen Microsoft Entra ID app credentials and Azure DevOps federated identities to reach 27 MSPs and their customers since November 1, 2026.

Hackers abused stolen Microsoft Entra ID application credentials and Azure DevOps identities to access Microsoft 365 and Azure environments, reaching at least 27 organizations. Todyl’s investigation describes an ongoing campaign targeting managed service providers and their customers since November 1, 2026. The operator targeted about 45 app registrations across roughly 18 organizations, with more than 33 authenticating successfully. Downstream access expanded the victim count to government, energy, agriculture, transportation, construction, legal, education, and nonprofit organizations. No Microsoft vulnerability was involved; the attacker used valid credentials to act as trusted applications. The latest reported attempt at 21:31 UTC on November 3 was blocked.

Unconfirmed: AI involvement remains a low-confidence possibility; the operator has not been identified.
