The Securonix Threat Research team has analyzed a sophisticated web-based multi-stage malware campaign. The attack chain unfolds across three distinct stages: (1) an obfuscated JavaScript loader injected into a compromised website, (2) a stealthy HTA (HTML Application) that executes encrypted PowerShell stagers via mshta.exe, and (3) a final PowerShell payload that downloads, extracts, executes, and establishes persistence for a Windows-based remote access Trojan.
