The rogue ads pose a number of problems. First, they can download malware to a computer once the ad is clicked on. The malware can include Trojans, back doors, and keystroke loggers and can be used by the scammers to commandeer the computer to send spam or launch attacks on other computers, according to Cluley.
Then, if someone falls for the ruse and provides credit card and other billing information, the scammers have sensitive financial data that can be used for identity fraud.
"Identity theft is the purpose behind the ads," said Caruso.
