Security researcher Andrey Meshkov, co-founder of Adguard, has discovered five malicious Ad Blockers extensions in the Google Chrome Store that had been installed by at least by 20 million users. The fake Ad blockers are AdRemover for Google Chrome (10 million+ users) and AdBlock Plus (8 million+) Adblock Plus, Adblock Pro and Webutation for YouTube are clone versions of well-known Ad blockers. The malicious code includes a modified version of jQuery library that hides the code to load a strange image from a third party domain.”]
