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.

Attack Summary
Announcement till 20/11 appears to be an entity in Germany classified in the broad Other sector, which suggests it does not fit a standard industry category such as healthcare, finance, or manufacturing. In threat-intelligence catalogs, such entries typically identify an organization or notice associated with ransomware activity without adding operational detail beyond the listing context. The record is indexed for Germany and uses the name as provided, indicating the subject of the entry rather than a full corporate profile. It was listed as a ransomware victim associated with brotherhood.

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
