About this tag
The clickfix malware tag covers campaigns that use fake CAPTCHAs, compromised websites, and misleading support posts to persuade people to run commands on Windows systems. Recent coverage examines how attackers abuse BNB Smart Chain smart contracts as a staging layer, while other campaigns spread through Steam forums by presenting malicious PowerShell commands as fixes for game problems. These attacks rely on social engineering: victims are instructed to open Run, Windows Terminal, PowerShell, or Command Prompt, paste clipboard content, and sometimes approve administrator access. Coverage also highlights the consequences, including XMRig cryptomining, and offers practical guidance for recognizing suspicious CAPTCHA instructions and forum-based fixes.
