ClickFix Campaign Uses Fake Windows Update Pages in Stealth

🛡️ Researchers at Huntress uncovered a ClickFix campaign that hides malware inside the RGB pixels of PNG images on a fake Windows Update page, tricking victims into pasting and running commands. The delivered payloads include the LummaC2 infostealer and the Rhadamanthys malware family, with active domains observed after a mid-November takedown. Huntress warns the steganographic technique and the realistic Windows Update motif increase the attack's stealth, and recommends disabling the Windows Run dialog and strengthening endpoint monitoring.
