For the first time, the FBI has issued a public warning about the threat of rogue anti-virus software, which the agency said has resulted in more than $150 million in losses to victims.http://www.scmagazineus.com/fbi-fraudsters-earned-150-million-in-rogue-av-scams/article/159597/
If there wasn’t money to be had, I doubt they would do it.
I would say that figure is likely to be much larger, especially if it isn’t a worldwide figure.
Not to mention anyone giving their credit card details to pay for a rogue antivirus or antispyware programs, could well suffer further fraudulent activity on their credit card.
I wouldn’t be surprised if it were in the billions. Just plain crazy I tell ya.
