HIGH VOLUME
The Interlock ransomware group, active since September 2024, has shown adaptability and innovation in its tactics despite a relatively low victim count. They employ fake browser updates and the ClickFix technique for initial access, followed by a multi-stage attack chain involving PowerShell backdoors, credential stealers, and a custom Remote Access Trojan. The group targets various sectors across North America and Europe, conducting Big Game Hunting and double extortion campaigns. Interlock has been observed improving their tools, including evolving their PowerShell backdoor and modifying their ransom notes to emphasize legal repercussions. The group's focus on maintaining relevance while avoiding large-scale visibility suggests a strategic approach to their operations.
