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
The Chester County Library & District Center was established in 1962 and moved to its current location in 1980. Largely supported by the County of Chester, the library serves as the District Center as well as the Chester County Library System headquarters. Although we serve primarily West Whiteland and Uwchlan Township residents, our expansive and comprehensive collection of nearly 328,000 items helps to support the other 16 member libraries in the system. The Henrietta Hankin Branch Library, also supported by the County of Chester, opened in July of 2003 to serve the northern region of Chester County. Our collection of over 93,600 items serves the residents of Upper Uwchlan and West Vincent Townships as well as several other townships in the area. Both libraries serve as community centers, providing work space, meeting rooms, homework and research help, and a wide variety of educational and cultural programs.

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.
