What Happened
KillSec operated as a ransomware-as-a-service platform, recruiting affiliates to deploy ransomware against targets and taking a percentage of ransom payments. The dismantling removes one RaaS operation from the active threat landscape but does not eliminate the affiliates who operated under the platform, who may migrate to other RaaS services.
