Attack Intelligence
Wesley Heating & Cooling was compromised in a ransomware attack attributed to sinobi in January 2026. The organization, operating in the Consumer Services sector in United States, was added to the group's data leak site as part of an extortion campaign.
sinobi 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.
