> Qilin ransomware operators claim Stryker compromise with 142 employee credentials and exfiltrated data.

Ransomware.live, a public tracking platform for ransomware operations, reports that Qilin ransomware operators have claimed a compromise of Stryker, a major medical device and software manufacturer. According to the posting, the attack resulted in 142 compromised employees, 24 compromised users, and 237 third-party employee credentials. The attackers also identified 85 items on the victim's external attack surface and obtained DNS records. Qilin has published a leak screenshot as evidence of the compromise.

Qilin is a known ransomware-as-a-service (RaaS) operation that conducts data extortion attacks, typically exfiltrating sensitive information before encryption to pressure victims into paying ransom. The claim against Stryker follows the group's established pattern of public disclosure via their leak site to coerce payment. Defenders at healthcare organizations and Stryker customers should treat this as active threat activity requiring immediate incident response investigation and credential compromise assessment.
