Entra Agent ID: Inside a cross-tenant agent compromise
A privileged agent in Microsoft Entra can be compromised through a vulnerable third-party blueprint, allowing an attacker to authenticate as any agent using that blueprint across multiple tenants. This attack vector parallels the Midnight Blizzard incident by enabling cross-tenant compromise through agent control. The risk stems from the trust relationship between agents and blueprints in the Entra environment.
Why it matters: Organizations using Entra agents with third-party blueprints face the risk of cross-tenant compromise if an agent becomes compromised; security teams should review agent blueprint sources and implement controls to detect unauthorized agent authentication.
