Malvertising is a technique cybercriminals use to target people covertly. Bad ads can redirect users to malicious websites or install malware on their computers. Users can get infected even if they dont click on the images. Malvertising groups will continue to prosper because its difficult to bring them to justice, says White Ops.com CEO Michael Tiffany. In 2017, Google blocked 79 million ads that attempted to send people to malicious sites and removed 48 million ads suggesting the installation of unwanted software.”]
