Boxbe uses two email authentication methods (DKIM and SPF) to verify that the emailer is who they claim to be. DKIM and SPF are two email authentication standards backed by Google, Microsoft, Yahoo!, and AOL. Boxbe blocks messages that come from senders who claim to be someone that they are not

Tuesday, September 11th, 2007

Ever wonder where spam, viruses and malware come from? Apparently, it comes from the mob.

Tony Soprano, spammer?

Auckland, New Zealand based computer security expert, Peter Gutmann has an informative presentation on the subject here. Malware, it seems, has become quite an industry and Gutmann posits that much of it is being ran by various mafias around the world.

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.

Additionally, he takes a technical deep dive into how malware authors hide what they are doing.
