Opera has introduced a new security feature called Paste Protect that automatically defends users against clipboard-based cyberattacks, including the growing ClickFix attack technique. The feature is now built directly into Opera’s desktop browser and is enabled by default, making Opera the first major web browser to offer native protection against these types of attacks.
Clipboard-based attacks have become increasingly common as cybercriminals look for ways to bypass traditional antivirus software. Instead of exploiting software vulnerabilities, these attacks trick users into copying and pasting dangerous commands into their own computers, allowing malware to be installed or sensitive information to be stolen.
A typical ClickFix attack often begins with what appears to be a harmless problem, such as a video refusing to play or a CAPTCHA failing to verify. Victims are instructed to copy a command and paste it into their computer’s terminal to “fix” the issue. Although the process appears legitimate, the command can secretly install malware, steal saved passwords, or even give hackers remote access to the device.
According to cybersecurity company Huntress, ClickFix attacks were responsible for more than 53 percent of malware-loading cyberattacks in 2025, highlighting how quickly this technique has become one of the most effective methods used by cybercriminals.
Opera says Paste Protect is designed to stop these attacks before they succeed by monitoring clipboard activity in real time. The browser can detect suspicious commands copied by users or placed on the clipboard by malicious websites across Windows, macOS, and Linux systems.
If Opera detects potentially harmful clipboard content, it immediately blocks the copy operation, displays a security warning explaining the risk, and shows a red warning icon in the browser’s address bar. Users can preview the first 120 characters of the blocked content, while advanced users and developers can choose to override the warning or mark trusted websites as safe.
The new feature also expands Opera’s existing clipboard hijack protection. That earlier protection prevents external applications from silently replacing copied information, such as changing a copied bank account number or cryptocurrency wallet address with one controlled by an attacker.
By combining clipboard hijack protection with the new injection detection technology, Opera now protects users from both malicious software attempting to alter copied content and websites attempting to trick users into executing harmful commands.
