Cybersecurity Firm, CloudSEK, Reportedly Breached

Executive Summary: A threat actor calling themselves 'sedut' claimed to have breached CloudSEK and offered internal screenshots, a video, and database/platform access for sale; CloudSEK's response found Vidar stealer on an employee laptop that exfiltrated JIRA session cookies and led to Confluence/JIRA access, with the company disputing some of the actor's broader claims about VPN and customer credential compromise.
