Fake ad blockers have been fooling people since at least 2017 – last year, 37,000 people installed a fake AdBlock Plus, which SwiftOnSecurity calls a "fraudulent developer that clones popular names and spam keywords." Like the AdBlock Plus Plus, AdGuard also detected spam keywords to get to the top of search results. Their creators just ripped out legitimate extensions and added a few lines of malicious code hidden in good-looking images ̵
Apparently, people do not care if the name of an extension is something lazy and generic like "AdRemover" and will download it as long as it's somewhere near the top. According to AdGuard, the fake ad blockers have enabled over 20 million users to install them. How can you avoid fake extensions? AdGuard says the best way to protect yourself is to check the author of an extension and make sure it's a company you can trust.
