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
nutexhealth.com zoominfo.com/c/nutex-health-inc/372032478 (NUTX, Nasdaq) — US healthcare company, based in Houston, Texas, founded in 2011 by Dr. Thomas Vo.
It runs 27 small "micro-hospitals" in 12 states — small hospitals with full 24/7 emergency rooms.
Model: fast, cheaper ER care between urgent care and giant hospitals; most revenue comes from Texas.
Q2 2026: net income $65.8M (vs loss a year ago), EBITDA $90M, cash $205M, debt only $31M.
Profit exploded because it wins 85%+ of insurance arbitrations (IDR) and got paid at higher out-of-network rates.
Plans: 7 new hospitals by 2027 plus two share buyback programs.
Main risk: the whole profit engine depends on the arbitration system — new regulation could cut it.
Cheap-looking: P/E around 6, but volatile small-cap with thin analyst coverage.

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
