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.

Legal Disclaimer:
This ransomware victim record reflects information published on the operator's leak site.
Breach.house only records what the operators themselves publish in the
open. 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.
Breach.house is not affiliated with, and does not act on behalf of, the
operators who publish this material. If you represent an organisation or
individual named here and want a record reviewed or removed, contact us
and we will act on it.
