Hackers use fake Semrush ads to steal Google accounts

Cybercriminals are using fake adverts for popular SEO platform Semrush to trick users into giving up access to their Google accounts, researchers have warned.

The malvertising campaign features ads that link to a bogus Semrush login page, which only allows users to sign in via Google, a tactic designed to steal high-value credentials.

According to Malwarebytes, Semrush accounts are often linked to critical Google services such as Analytics and Search Console.

These tools store confidential business insights, which threat actors could exploit for strategic and financial gain. The scammers may also access names, phone numbers, business details, and partial card information through compromised Semrush accounts.

By impersonating Semrush support, attackers could deceive users into revealing full card details under the pretence of payment or billing updates. However, this may open the door to wider fraud, such as redirecting funds from vendors or business partners.

With Semrush serving over 117,000 customers, including a significant share of Fortune 500 firms, the attack underscores the growing risks of malvertising on platforms like Google.

Security experts are urging businesses to tighten account access controls and remain cautious when engaging with search ads, even from seemingly reputable brands.
