About

Written by ThreatCluster from 1 stories

Kairos is a ransomware group operating an extortion-focused model, claiming to exfiltrate data from victim networks to pressure payment. The group has 92 victims claimed, and it targets Education, Healthcare, Manufacturing, Business Services, and Consumer Services sectors, with the United States, Australia, the United Kingdom, Canada, and Denmark among the most affected countries. Recent reporting shows a pattern of data-exfiltration as the extortion method, illustrated by a Bedfordshire Hospitals NHS Foundation Trust incident in June 2024 where attackers accessed and extracted internal files affecting about 32,927 patients, with Kairos claiming to have exfiltrated data from the network.
