Sibbalds

Sibbalds was compromised in a ransomware attack attributed to rhysida in October 2025. The organization, operating in an undisclosed sector in United Kingdom, was added to the group's data leak site as part of an extortion campaign.

rhysida 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.
