The Scenario: Downloading Google Authenticator
Imagine a scenario where you are looking to download the Google Authenticator app. You run a search on Google, and the first link that appears is listed as sponsored. The link looks legitimate as it shows Google’s official site as the URL and even indicates that Google has verified the advertiser’s identity. However, downloading the app from this link would install a malware-infested authenticator application on your device.
Malware Threats and Bypassed Security Systems
This particular application, while appearing trustworthy, installs the Deerstealer information-stealing malware on Windows devices. This isn’t an isolated incident; threat actors have repeatedly found ways to overcome the security systems of major advertising companies like Google. These malicious ads have been reported numerous times, including instances where malware was distributed at alarming rates via Google Ads just last year. The situation has shown minimal improvement, posing ongoing risks to users.
Google’s Ongoing Battle Against Malicious Ads
Despite Google’s efforts, including the removal of 3.4 billion ads and the suspension of 5.6 million advertiser accounts in 2023, they have not yet found a foolproof method to eliminate all malicious ads from Google Search. Threat actors use sophisticated techniques like creating thousands of accounts simultaneously and employing text manipulation and cloaking to evade detection. This means that sponsored links on Google are not always trustworthy.
The Safe Approach: Trust Organic Search Results
The key takeaway is to avoid clicking on sponsored or ad-listed links, particularly when downloading software or engaging in financial transactions. Users are advised to scroll down to the first organic search results to find the official website listing of the desired product. Sponsored links have been misused far too often by malicious actors, making them inherently risky.
