Malvertising

 Hackers used fake ads on Google to trick users into downloading a malicious AnyDesk application. The ad campaign ranked higher in downloads than even the real AnyDesk ads. Researchers estimated that over 40% of users who clicked on the fake ad, downloaded and installed the malware, showing that this was a very successful strategy for the fraudsters. While Google does some automated and human reviews to block malvertising, experts advise it needs to do more to develop better screening to block malware in ads.
