> Qilin ransomware operators claim breach of Commission de la construction du Quebec with 485 compromised employees.

Ransomware.live, a public ransomware leak tracking platform, reports that Qilin ransomware operators have claimed a breach of Commission de la construction du Quebec (CCQ), a Quebec-based construction industry regulatory body. The operators claim to have compromised 485 employees and 221 users within the organization, along with one set of third-party employee credentials. The attack surface reconnaissance identified 37 DNS records and other external infrastructure details. The breach appears to have been discovered through infostealer malware infections leading to credential compromise and subsequent ransomware deployment—a common attack chain where commodity malware harvests credentials that are then leveraged by ransomware affiliates for lateral movement and encryption. This represents a typical medium-severity ransomware affiliate operation targeting a specific organization rather than a mass-exploitation event.
