Chrome Targets ClickFix Copy-Paste Scams

Help Net Security · Medium sophistication
Last updated October 20, 2026

Google is updating Chrome Enhanced Protection to warn people when scam websites try to trick them into copying and running harmful commands. These ClickFix scams use fake computer problems, such as bogus browser or antivirus alerts, to move victims from the browser into a terminal where security download protections may be bypassed.

Key findings

  • ClickFix scams present a fake problem and instruct victims to copy and run a command as the supposed fix.
  • The command copied to the clipboard may not be the same command visibly displayed on the scam page.
  • Attackers commonly use trusted built-in tools such as PowerShell and cmd.exe to download or install malware.
  • Running the command through a terminal can move the malicious download outside Chrome's normal download protections.
  • Chrome Enhanced Protection will analyze suspicious copied commands and show a warning when a command is considered dangerous.

Who’s being targeted

  • Commonly targeted roles: All employees, Remote and hybrid workers, Executives, Finance personnel, IT support teams, Users with local administrative access.
  • Affected industries: All industries using Chrome on managed or personal work devices.
  • Attack channels: website.
  • Impersonated: Browser security, antivirus software, or technical support.

Awareness takeaways

  • Never copy and run commands from a website to fix a browser, antivirus, or computer problem; close the page and report it to IT or security.
  • Treat any website that directs you to open PowerShell, Command Prompt, or another terminal as suspicious, especially when it claims to solve an urgent technical issue.
  • Do not assume the command you see on screen is the same one that will be pasted onto your computer.
  • Enable Chrome Enhanced Protection where organizational policy permits, but treat browser warnings as a safety net rather than permission to proceed.

Red flags to watch for

  • A website asks the user to open a terminal or command prompt.
  • The alleged fix requires copying and running a command rather than using a normal browser or software update process.
  • The command shown on the page may differ from the command placed in the clipboard.

A website says your browser is broken. Its fix? Open PowerShell. That's ClickFix: a fake browser or antivirus alert tells you to copy a command. Here's the catch: what lands on your clipboard can differ from what the page shows. Paste it into PowerShell or cmd.exe, and it can download malware outside Chrome's normal download protections. Chrome Enhanced Protection may warn you, but that's a safety net. If a website asks you to run a command as a fix, close the page and report it to IT.
