Gregory Jewellers

Gregory Jewellers was compromised in a ransomware attack attributed to kairos in April 2026. The organization, operating in the Consumer Services sector in Australia, was added to the group's data leak site as part of an extortion campaign.

kairos 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.
