When a website tells you to “copy this command to fix the issue,” you may not know it, but the command in question could be malicious. These are called ClickFix attacks, ClickFix attacks sidestep nearly all existing defenses, including antivirus and email filters. The reason: Those systems are designed to check for threats from external sources, not for commands typed or pasted by the user. According to Opera, over half of malware-loading cyber attacks in 2025 were of the ClickFix type. In fact, fake CAPTCHA attacks spiked by 563% last year. This social engineering technique can be adapted to various access scenarios, but in general, ClickFix aims to take advantage of human problem-solving. Fake error messages, for example, could request users to fix a minor technical problem by copying and pasting code or launching commands on their system. What is your experience with malicious clipboard content?
