What is the increasing "ClickFix" attack? Be cautious of instructions prompting you to press shortcut keys and more.

"ClickFix" is a social engineering initial intrusion technique that displays fake error pop-ups and fake CAPTCHAs like "I'm not a robot." It tricks users into executing shortcut operations such as Win+R → Ctrl+V → Enter, which then runs PowerShell or other commands embedded in the clipboard. Since it was first observed in the spring of 2024, it has expanded to include **fake CAPTCHAs and fake conference tools (Google Meet/Zoom)**, and is used to deploy malware such as Lumma Stealer, NetSupport RAT, and DarkGate. Variants that use Win+X and those that utilize the Explorer address bar, known as "FileFix," have also emerged, with cases targeting non-Windows systems (macOS/Linux) being reported. In Japan, multiple SOC operators have observed incidents and issued warnings. It is crucial to never follow browser instructions to press shortcuts or paste commands. Urgent measures include technical countermeasures (PowerShell restrictions, application control, browser defenses, EDR/log monitoring) and education and awareness.
