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
confluent.io Revenue $1.16 Billion Confluent is the enterprise data streaming platform built on Apache Kafka that lets companies process live events like payments, orders and sensor data in real time, and it is now owned by IBM which bought it for about $11 billion in March 2026. It ended 2025 with 6,690 customers including roughly 40% of the Fortune 500 and grew revenue 21% with its cloud segment alone growing 27%. Customers include BMW, L'Oreal, Michelin and Ticketmaster and the platform runs across 60+ cloud regions on AWS, Azure and Google Cloud. Money comes from cloud usage and software subscriptions, about 96% of revenue, paid for compute and data transfer rather than per-seat fees. Around 3,241 employees worked at Confluent across 27 countries before the IBM deal and it owns no factories or stores because its product is pure software and cloud. Confluent was still unprofitable with a $295 million loss in 2025 though it earned positive operating income excluding stock pay.

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.
