> Qilin ransomware operators claim to have compromised Malaysian conglomerate Sunway Berhad with exfiltrated data.

Ransomware.live, a public tracking platform that indexes ransomware operator leak posts, reports that the Qilin ransomware gang has claimed responsibility for compromising Sunway Berhad, a major Malaysian conglomerate. The operators claim to have compromised 63 employees and 509 user accounts, along with 142 third-party employee credentials and identification of 128 external attack surface points. The post includes DNS record details and a leak screenshot, indicating the attackers accessed and exfiltrated data from the organization.

This represents an active Qilin campaign targeting a large regional organization. The specific numbers of compromised accounts and external exposure points suggest the attackers conducted reconnaissance and obtained persistent access across multiple systems and identity stores. Defenders at Malaysian organizations and those with connections to Sunway should review access logs, credential exposure reports, and infostealer telemetry for evidence of similar compromise chains.
