Opera Launches Paste Protect to Combat ClickFix and Clipboard Hijacking Attacks

The internet can be a cruel place, especially if you don’t pay attention to the websites, you visit and blindly copy and paste commands from them. Unknowingly, you could be a victim of cyberattacks, a nightmare for anyone in any given day. Well, worry not. Opera finally has you covered, thanks to its new security feature called Paste Protect.

Opera becomes first major browser to block ClickFix attacks with new Paste Protect feature

The company, in its announcement blogpost, claims that it is the first major browser to ship built-in protection against the rapidly growing ClickFix attack technique. Per Opera, Paste Protect is now rolling out across its desktop browsers on Windows, macOS, and Linux, and it’s enabled by default.

That means you won’t need to install extensions or change any settings to receive protection against clipboard-based attacks. The company says the feature is designed to stop malicious content before users accidentally execute it on their own computers.

In case you are unaware, ClickFix attacks have become increasingly popular because they rely on social engineering rather than exploiting software vulnerabilities. Victims usually get tricked by a fake CAPTCHA, broken video player, or troubleshooting prompt that instructs them to copy and paste a command into their system terminal.

While the process appears legitimate, the pasted command can instead install malware, steal passwords, or even hand attackers remote access to the device. Opera cites cybersecurity firm Huntress, which says ClickFix accounted for more than 53% of malware-loading attacks in 2025.

Opera’s new system focuses on the clipboard itself. The browser now monitors copied content for suspicious command patterns commonly associated with ClickFix campaigns. If a dangerous command is detected, Opera immediately blocks the copy action, displays a warning explaining the potential risk, and flags the affected webpage. Developers and advanced users can still override the protection or whitelist trusted sites if necessary.

Speaking of security, Paste Protect also expands Opera’s existing clipboard hijacking protection. Besides detecting malicious scripts copied from websites, it also prevents external applications from secretly replacing copied content, such as cryptocurrency wallet addresses or bank account numbers, before users paste them elsewhere.
