[Updated] Cyber Security Incident at CloudSEK

CloudSEK investigated a targeted compromise where a third-party-serviced laptop returned with Vidar stealer installed; the malware exfiltrated session cookies and credential data that an attacker used to access a Jira account and internal Confluence/Jira documents. The actor published screenshots and limited customer information (names and POs for three companies) and briefly compromised a secondary Twitter account; CloudSEK reports no access to databases, source code, or production platforms and implemented improved device quarantine, EDR, access controls, and monitoring.
