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
ym.com.tr rocketreach.co/yapi-merkezi-profile_b5c7f2fff42e0db7 YM Group is a Turkish family-owned manufacturing and brand house founded in 1986 in Istanbul by Yüksel Mehmet Yıldırım, built on a flexible-packaging plant in Çorlu (Halal-certified, exporting to Europe/MENA). Its crown jewel: it owns and operates the legendary American trail-running brand Ultimate Direction (the 1935 inventor of the hydration pack) — designing, manufacturing in Turkey and distributing it worldwide — plus its own jewelry line Ela by YM and investment arm YM Capital. The group follows the classic ladder: manufacturing → own brands → capital, with Halal certification as a niche edge for Gulf/Asian markets. Small core team (~110), private, low-profile, no public financials. Bottom line: a quiet Turkish industrial family that turned commodity packaging profits into ownership of an iconic American outdoor brand.

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
