> Qilin ransomware operators claim compromise of Otthon Centrum with 323 affected users and data exfiltration.

Qilin ransomware operators have publicly claimed a breach of Otthon Centrum, a Hungarian financial services organization. According to the listing on ransomware.live, the incident involved compromise of 8 employees, 323 user accounts, and 66 third-party employee credentials. The attackers also identified 100 items on the victim's external attack surface and obtained DNS records from the victim's domain. This appears to be a standard ransomware extortion claim where data exfiltration precedes encryption, using the threat of data publication to pressure the victim into paying a ransom. The specific attack methods, initial compromise vector, and timeline are not detailed in the available reporting.
