Hidden Messages in Spam

randomwalker writes "There was an extremely interesting presentation at the Blackhat Windows Security Conference in January by Dr Curtis Kret entitled Nobody's Anonymous. In his presentation he showed how information about spammers can be determined. In addition he showed that some spam is being used as a covert communication channel. This presentation demonstrates how to apply data forensics to spam in order to identify the sender of specific spam messages. Some senders can be identified by name, while others can be distinguished by attributes such as preferences, nationality, religion, and even left-handedness. Four spam categories are provided that classify spam by function, including List Makers, Scams, and Covert Communication channels. The examples provided include full-disclosure case studies: a phishing gang that targets bank customers with malware and impersonations, and an IRC group that uses spam as a covert communication channel."

    And that'd make you a troll. At least we've got our species, genus and phylum in check. Anything else?

    Hello! People! There is a 600lb gorilla in the room. Think! This is just another scare tactic.

    George W. Bush, and the other powers that be are going apeshit over the internet because they can't control it.

    Bill Gates tosses and turns all night thinking about millions of email whizzing about from which is making not a cent.

    Surely, there's an answer to both problems. I know, let's tell the people they need to be protected from spam! They want to protect us from spam because it's annoying, because it's immoral, and now because terrorists are using spam to send secret messages?

    Good grief, we've seen this same tactic so many times. Spam can be annoying, I agree, but in this case the cure is far worse than the disease.

    They are trying to scare us into allowing them to regulate the internet, or at least charge us for email.

    More importantly, all of this communication scares them to death. They are afraid the great unwashed will discover the man behind the curtain.
