A recent FBI public service announcement highlights that cyber criminals are using search engine advertisement services to abuse users’ trust of brands to direct them to malicious sites that deliver ransomware and conduct credential theft.

Falsely-branded ads as the lure
According to the announcement, attackers are creating ads using logos and similar domains of trusted brands to trick users into clicking on the ads and visiting the malicious sites. A similar technique is often used in phishing attacks utilizing email as the attack vector. Since many antiphishing services already exist to protect users inside their email clients, this tactic is designed to bypass any checks done on email entirely.
Because the ads look legitimate and are related to something the user is conducting a web search for, the user may be more likely to take the malicious action on the page they are visiting. For instance, if they received the ad by searching for a piece of software they want to download, and both the ad and the page they visit look legitimate, the likelihood the user will download the software is greater than it would be if they received an unsolicited email with the same link.
To make matters even more confusing, these ads target the same keywords as the legitimate site so these malicious ads can appear above legitimate results. This creates an extra layer of confusion for the end user and increases the likelihood they will click on the malicious link instead of the legitimate one.
How can companies protect themselves?
Most of the countermeasures suggested by the FBI revolve around educating users and asking them to take extra precautions whenever they click on ads. These suggestions aren’t enough. No matter how much training they have or how careful they think they’re being, users will always make the wrong decision at some point.
