clickfix attack

ClickFix attacks are a social-engineering family that tricks victims into copying and pasting malicious commands into OS dialogs or terminals. Recent campaigns have evolved to include a convincing fake Windows Update screen, automatic clipboard poisoning, PNG steganography, and a .NET Stego Loader. These techniques shift from simple social engineering to multi-stage, fileless delivery methods that are harder to detect and remediate. The attack chain often involves fake error pages or update prompts that instruct users to run PowerShell commands, ultimately deploying payloads like infostealers or remote access trojans. Understanding these tactics is crucial for Windows users and IT administrators to recognize and defend against ClickFix attacks.
