There is a PSA Blog on adguard.com warning the general public about two very popular ad blocker extensions located in the Google Chrome Web Store. Basically the blog warns that the ad block extensions that appear as the top two search results are actually fakes.
Tom’s Hardware reported on this and stated that “the real purpose of these fake ad blocking extensions is “cookie stuffing,” which is used as an ad fraud scheme. The creators of the fake extensions stuff them with affiliate cookies, so that when the users of the extensions visit a relevant e-commerce site (such as Amazon) and make a purchase, the creators of the fake extensions get paid the affiliate commission for that purchase.
The two extensions have 1.6 million active users and are stuffing cookies from 300 websites from Alexa Top 10000 most popular websites, AdGuard said, saying it studied the extensions' code. AdGuard believes that these malicious actors are making millions of dollars a month.
"The two extensions, called AdBlock by AdBlock Inc. and uBlock by Charlie Lee, also mislead users by mimicking names of two real ad blocking extensions, as well as the names of the developers behind those extensions. Users have reported these extensions as fake, but Google has seemingly yet to take action.”
So if you are a Google Chrome user, and you have an ad block extension installed, you should double check your extensions now to make sure what you have installed is not one of these culprits. If you find that you are a victim of this scheme, immediately uninstall and head to the Chrome Web store to help get Google’s attention by reporting these extensions as the fakes that they are.
