tenant takeover

Tenant takeover refers to the scenario where an attacker gains control over a Microsoft 365 tenant, effectively operating the cloud control plane for identity, email, collaboration, device policy, security tooling, compliance workflows, and AI-assisted processes. This risk goes beyond simple data theft, as the attacker can manipulate the entire tenant infrastructure. Discussions on WindowsForum.com highlight that many organizations still secure Microsoft 365 like an application subscription, leaving them vulnerable to tenant takeover. The platform's evolution into core business infrastructure demands a shift in security mindset to protect against this threat.
