A Russian-speaking threat actor operating QuasarRAT v1.4.1 infrastructure. The actor used a live C2 at 91.124.98.29, migrated from port 2525 to 2626, and appears to protect the C2 with application-layer IP-based access control that accepts TLS handshakes but immediately drops unauthorized clients after they send data.
