About

Organization deletion and bulk delete remove tenant data, projects, and member access in a single administrative action. An attacker can use this to break AI-assisted workflows as an impact technique, to extort the organization, or to destroy evidence after finishing a data export. Once deletion progresses, recovery options shrink and earlier exfiltration activity is harder to reconstruct from the tenant itself.
