Malvertising Scam on Google Ads: Malvertising, or malicious advertising, has become a significant cybersecurity threat, targeting users through Google Ads. Cybercriminals are creating fake ads that appear legitimate but redirect unsuspecting users to phishing sites.
These sites are designed to steal sensitive information such as login credentials and two-factor authentication (2FA) codes.
This scam poses a significant risk to individuals and businesses. By compromising accounts, attackers can misuse them for fraudulent activities, including running malicious ad campaigns or distributing malware.
Key Takeaway to Malvertising Scam on Google Ads
- Malvertising on Google Ads uses fake ads to redirect users to phishing sites that steal login credentials and two-factor authentication codes, posing significant risks to individuals and businesses.
How Does the Malvertising Scam Work?
The scam uses deceptive tactics to exploit users’ trust in Google Ads. Here’s how it unfolds:
- Fake Ads on Search Results: Fraudsters create ads mimicking official Google Ads links. These appear prominently as “Sponsored” results when users search for terms like “Google Ads login.”
- Redirection to Phishing Sites: Clicking on these ads takes users to phishing pages hosted on Google Sites or other domains. These pages look identical to the real Google Ads login page.
- Credential Theft: Users who enter their login details and 2FA codes on these fake pages inadvertently provide this information to attackers.
Once stolen, these credentials are used to access accounts, often leading to unauthorized transactions or further phishing attacks.
Why Is This Scam So Dangerous?

- Sold on dark web forums.

The damage isn’t limited to financial loss. Businesses also face reputational harm and disrupted operations.
