Cosmon
beastThis record tracks a ransomware attack claimed by the beast group against Cosmon. 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
Cosmon develops agentic artificial intelligence software for mechanical engineering workflows, centered on its Nexus product for CAD, CAE, simulation, and PLM tasks. Its website presents the company as a software provider whose platform automates drawing creation, simulation setup, troubleshooting, design validation, and product lifecycle data tasks while integrating directly with major engineering tools. Although the offering is deeply technical and tailored to engineering environments, the core business shown is the development and delivery of proprietary engineering software rather than providing outsourced engineering services or general consulting. https://cosmon.com https://www.zoominfo.com/c/cosmon/5000578320
