Halcyon Technologies

Halcyon Technologies was compromised in a ransomware attack attributed to sinobi in February 2026. The organization, operating in an undisclosed 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.

Halcyon is the industrys first dedicated, adaptive security platform that combines multiple proprietary advanced prevention engines along with AI models focused specifically on stopping ransomware. Halcyon is built by offensive security experts to stop attackers.
