Campaign
Summary
Hide ▲
Show ▼
The JackFix campaign is using fake adult websites and ClickFix lures to trick users into running malicious commands, enabling an infection chain that can drop stealers and RATs. The operation disguises itself as a critical Windows security update and uses malvertising and other social-engineering routes to reach victims. Once users comply, the chain can launch mshta.exe and PowerShell stages that fetch additional payloads and evade analysis.

JackFix ClickFix fake adult site campaign disclosed
Initial DisclosureCybersecurity researchers identified JackFix as a ClickFix campaign that uses fake adult websites and phony Windows Update full-screen lures to trick users into running mshta.exe commands that fetch PowerShell payloads. The chain uses obfuscation and anti-analysis measures, can elevate privileges with Start-Process and "-Verb RunAs", creates Microsoft Defender Antivirus exclusions, and can deliver loaders and RATs including Rhadamanthys Stealer, Vidar Stealer 2.0, RedLine Stealer, Amadey, and other payloads. A related Huntress-described chain also uses a ClickFix lure masquerading as Windows Update and steganography to hide shellcode in an embedded PNG, enabling Lumma or Rhadamanthys delivery.
