> Qilin ransomware gang claims to have compromised Hemmersbach GmbH, a German IT distributor, exfiltrating data.

Ransomware.live, a platform that indexes publicly posted ransomware claims, reports that the Qilin ransomware group has claimed responsibility for compromising Hemmersbach GmbH & Co. KG, a German IT distributor and reseller. According to the posting, the compromise affected 201 employee accounts, with 124 unique compromised users identified and 95 third-party employee credentials exposed. The group claims to have identified 143 points on the victim's external attack surface, including DNS records and other internet-facing infrastructure. The claim includes a leak screenshot, suggesting data exfiltration as part of the attack.

This report indicates that Qilin is actively conducting operations against mid-market IT infrastructure companies. The scale of compromise—particularly the exposure of third-party credentials—suggests lateral movement capability or supply-chain access risk. Defenders in the IT distribution and reseller space should assess their exposure to similar intrusion patterns, particularly around VPN access, email compromise, and multi-factor authentication bypass. The specific attack vector is not detailed in this public claim.
