In recent months, scammers have begun using Google ads and the popular design platform Canva to trick unsuspecting users into interacting with fake pages designed to mimic trusted sites. Malwarebytes found that fraudsters created accounts on Canva and used them to generate deceptive designs resembling Canva’s homepage. When users click on these designs, they are redirected to a fake Microsoft alert claiming that their Windows system is locked due to “unusual activity,” effectively hijacking their browsers.
This attack relies on a clever social engineering tactic that leverages people’s trust in well-known brands and Google’s ad results. Ads linking to these fraudulent Canva pages often appear at the top of Google search results, making them seem legitimate to users who are merely searching for design tools. As users land on the fake page, it closely mirrors Canva’s interface, including a convincing “Start designing” button that ultimately leads to the fake alert, catching many by surprise.
When users click on the “Start designing” button, their browsers are redirected to an external URL, controlled by the scammers, that displays the false security alert. The alert warns users that their system has been locked due to “unusual activity” and attempts to instill fear to prompt quick reactions from victims. By using Canva’s design platform, these fraudsters create realistic replicas of trusted sites, adding to the deception and likelihood of user engagement.
Malwarebytes has reported this malicious campaign to both Google and Canva, stressing the need for platforms to strengthen their monitoring and security features. The cybersecurity company also advises users to employ tools like their Browser Guard extension to help detect malvertising schemes. Malwarebytes remains committed to tracking these types of online threats and raising awareness about tactics used to deceive users, encouraging people to stay vigilant when interacting with online ads.
