ClickFix is a mature Malware-as-a-Service attack methodology that uses fake verification prompts to silently poison the user's clipboard with malicious commands, which are then pasted into Windows Run or macOS Terminal. The execution chain relies entirely on living-off-the-land binaries (PowerShell, mshta.exe, curl, rundll32.exe), making it invisible to traditional EDR and AV tooling. A specific watering hole attack on a university site delivered zuhe.dll, a Go-based RAT, using blockchain-based C2 via Ethereum smart contracts to evade infrastructure takedowns.
