ClickFix attacks are tricking Mac and Windows users into hacking themselves

If you clicked on an HBO Max ad on Reddit over the past week, you might want to check your computer for malware.

These so-called “ClickFix” attacks have quickly become one of the rising cybersecurity threats of 2026, and they’re getting both sneakier and compromising people’s devices with greater frequency. Until recently, ClickFix attacks were a rarity, capitalizing on people searching the web for quick tech fixes. They have since evolved into a massive international effort to hack into people’s computers.

The attacks involve fake websites, or legitimate websites that have been hacked, which display a message that appears to look like a CAPTCHA or an anti-bot checkbox. Once clicked, a prompt appears asking the user to perform a “check” to proceed, which gives instructions to copy and paste a string of text into the user’s Windows command prompt or Mac Terminal app.

As soon as the user hits return, they unwittingly and instantly install info-stealing malware on their computer, capable of immediately stealing their passwords, access to their logged-in accounts, and crypto wallets. Since the user is working in the computer’s terminal, which lets them interact directly with the operating system using text-based commands, many of these attacks evade antivirus and security defense tools.

Security researchers now say that the latest ClickFix campaign they’ve seen involved hackers posting fake ads on Reddit, linking to a page that looks like HBO Max but contains a ClickFix lure that tricks people into hacking themselves. The hackers compromised the official HBO Max’s account on Reddit that was then used to post hundreds of fake but real-looking adverts to the news-sharing site, according to security researchers at Hudson Rock and a thread on Reddit’s cybersecurity subreddit.
