Organized crime recruit so-called “script kiddies” that are writing malware and viruses for fun and pay them to turn their software into money making machines. Gutmann cites a number of internet business practices that have been employed by such as “Malware as a Service,” making it easier than ever to spam people.

A deal you can’t refuse

Gutman, the self proclaimed “professional paranoid,” goes into a high level of detail of exactly how people in the malware industry make money.

Here are a few examples:

  • $1 per credit card numbers down to the verification number
  • $40 credit card, with date of birth and social security number
  • $1000 for 10,000 compromised computers.
