Ernst & Young
shinyhuntersThis record tracks a ransomware attack claimed by the shinyhunters group against Ernst & Young. It collects the publicly disclosed attack details — sector, location and timeline — as published on the operator's leak site and indexed by Breach House.
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
Yes it was us. Now come talk to us. We have been trying to reach you. If you do not come talk to us within the given deadline, we fully and completely intend to release all the data and files. This is a final warning to reach out by 31 July 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: 27 July 2026 | Warning: FINAL WARNING PAY OR LEAK
