About this tag
ClickFix is a social-engineering attack family that tricks victims into copying and pasting malicious commands, often disguised as fake Windows Update screens or other trusted interfaces. Recent campaigns have evolved to include sophisticated techniques such as abusing finger.exe and the Finger protocol (TCP 79) for covert payload delivery, using PNG steganography and .NET Stego Loaders for in-memory execution, and deploying fake OAuth apps to steal Microsoft 365 credentials. These attacks target Windows users across sectors including government, healthcare, and hospitality, delivering infostealers like LummaC2 and Rhadamanthys. The tag covers threat analysis, attack chain breakdowns, and defensive guidance for Windows environments.
