Remember Economy of Cybercrime? I hope so! There I made the statement that Cybercrime has to pay off.
On Zone-h today they summarized a research from G DATA with the title How much can cyberterrorist get? In there you see how much you have to pay for which "service". This is a pretty good income:
Doing simple math - working for just 20 hours per month, on 20 orders, spammer can send over 400 millions of messages and without much effort he could earn around 7000 euro. If that wasn't enough, you can get 10 millions of e-mail addresses for just 100 euro. Same goes to paypal accounts, credit cards numbers and internet game account's.
