Archer Health

Archer Health was compromised in a ransomware attack attributed to killsec3 in October 2025. The organization, operating in an undisclosed sector in Unknown, was added to the group's data leak site as part of an extortion campaign.

killsec3 operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.
