Window Zero
EXPOSURE GAPWindow 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
Hundreds of thousands of records containing PII (SSN, DOB, etc.), W-2 tax records, pay data, physical scans of government identity documents, drive licenses, and a lot more was compromised. This is a final warning to reach out by 15 June 2026 before we leak along with several annoying (digital) problems that'll come your way. Make the right decision, don't be the next headline. | Updated: 12 June 2026 | Warning: FINAL WARNING PAY OR LEAK
