> Direwolf ransomware operators claim compromise of AliveCor, Inc., exposing 489 user accounts and exfiltrating data.

Ransomware.live, a tracking platform that indexes ransomware gang leak claims, reports that the direwolf ransomware gang has posted AliveCor, Inc. as a victim. According to the listing, the compromise affected 489 user accounts, with one third-party employee credential also exposed. The attackers identified 100 external attack surface elements on the victim's domain. AliveCor is a healthcare technology company specializing in mobile cardiac monitoring devices and services. The listing indicates data exfiltration occurred as part of the attack, though specific details of the compromise method and timeline are not provided in the source material. This represents a data extortion claim by a known ransomware-as-a-service affiliate rather than detailed technical breach reporting.
