Threats Tagged 'compromised websites'

A sophisticated ClickFix campaign has been uncovered, compromising legitimate websites to deliver a multi-stage malware chain. The attack culminates in MIMICRAT, a custom remote access trojan with advanced capabilities. The campaign uses compromised sites across industries and geographies for delivery, employing a five-stage PowerShell chain that bypasses security measures before deploying a Lua-scripted shellcode loader. MIMICRAT, the final payload, is a native C++ RAT featuring malleable C2 profiles, Windows token theft, and SOCKS5 proxy functionality. The attack chain involves multiple compromised websites, obfuscated scripts, and sophisticated evasion techniques, demonstrating a high level of operational sophistication.

Interlock, a relatively new ransomware group first observed in September 2024, has gained prominence in 2025 as an opportunistic ransomware operator. Unlike traditional Ransomware-as-a-Service models, Interlock operates without affiliates or public advertisements. The group conducts double extortion campaigns, leveraging compromised websites and multi-stage social engineering techniques to deliver payloads. Interlock's attack chain involves initial access through fake software updaters, execution of PowerShell scripts, and the use of custom remote access trojans. The group has targeted various sectors across North America and Europe, including education, healthcare, technology, and government entities. Notable attacks include the DaVita breach in April 2025 and the ransomware attack on the city of St. Paul, Minnesota in July 2025.
