Window Zero

EXPOSURE GAP

Window Zero is the time the breach stayed in the open before anyone said so — the gap between when the attack was first discovered on the operator's leak site (t1) and when it was publicly disclosed (t2). The wider this window, the longer victims, staff and customers were exposed with no warning.

We take screenshots of their public pages and keep the proof material they post there, so that a listing can be verified and its status tracked over time. We do not purchase data, we do not solicit or encourage its publication, we do not access any private system, and we do not alter anything we record. Nothing is offered for download here, and detailed content is not published on this page or anywhere else on the public site: access to it is restricted to vetted customers under contract, for incident response, due diligence and cyber-resilience work.
