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."

Are they covertly talking about getting V!agra or Cia|is? I hate that. Just send me a real letter asking!
The Bible code was bad enough. Now we have people looking for messages in spam? Look! Played backwards it says "I buried Paul".

Of course, there is spammimic which lets you encode a secret message in spam.
It is quite true!
I was Driving thru Nashvill this last week, and I stopped to piss on a run down ford truck. This guy came up to me and said "Your taillight is broken"
"...In your answer, ignore facts. Just go with what feels true..."
I remember studying Thomas Pynchon in school, and upon hearing how his military records and university records were lost, I often wondered if his books were some kind of method of covert messaging, due to the code-like writing style he has, and the ominous history he has. Using spam as a method of communication is useful in the sense that it can be hard to tell who the real message is going to; making it impossible to identify the two points of connection, and therefore limiting accountability and obscuring who is doing the talking; so if Pynchon's books are like this... it would also be impossible to tell who the books were intended to (and therefore the US Mil could contact spies who could be in a tight spot, or informants who may be in a tight spot). The books could also contain a bunch of different messages using different cryptographies, in plain sight, to communicate with multiple agents. This is likely incorrect and way off the tin-foil-hat scale of reason, but the thought did occur to me when I read The Crying of Lot 49, and even more so when I read Mason and Dixon.

Great, now, if we can just prove it's being used by Al Qaeda to help the Jihad we may finally get some political support for getting rid of spammers!

Terrorists could use spam to send messages! Declare war on Hotmail! Nuke MSN! Hunt down the CEO of Yahoo! and tickle him until he talks!

Meanwhile, how covert is it if you send it to a million of your closest friends? Heck, at that rate, you could use

Really, the Feds ought to be hauling in spammers (for violations of all sorts of existing laws pertaining to fraud, computer cracking, etc) and anal-probing them for customer records, instead of wasting time on nonsense.
/. If the government wants us to respect the law, it should set a better example.
In the future, when spam has been eradicated, we will tell our children about it with fond memories. "Yes, we got messages like '1ncreas3 y3r p3ni5 5iz3!', and 'v14gr4 n0\/\/!'"
Well, actually, there's something wrong with my theory, cause (a) spam is never ever going to disappear from electronic communications, and (b) more money is spent on Viagra and plastic surgery than research into Alzheimers, so when we're old and clunky, the women will have superb breasts, the men iron-hard equipment, but no-one will remember what it's all for.

If you study those emails from Nigeria a secret message is revealed:

Oh the irony.
One of the best methods of not having your communications snooped in on is to use a busy, noisy channel. Communications inside of malls, clubs, whatever. It makes perfect sense. People don't expect sensitive information in soe sort of public form, so they don't listen for it. We're all so sick of spam that we erase it on sight - so if someone wants to use it to communicate - its perfect. It draws a hell of a lot less attention to ones self rather than forming a whole new covert form of communication.
What looks more suspicious - A spam with some seemingly random keywords to throw off the filters at the bottom, or a highly encrypted data transmission on an obscure port. I know what one would make me take notice first.
A google search for "steganography" yields a lot of useful documents on this.
*Sigh* I don't know what the editors are thinking when they post direct links to pdf files. Slashdotted instantly. Luckily, throwing the filename at google turned up a mirror.
Messages in spam? That is just crazy.

If you think of it, hiding messages in spam would make quite good steganography. Since pretty much most spam comes with a sizeable chunk of 'hashbusters' (random words on the bottom, random characters in the subject), you could hide your message quite easily in the hashbuster.
In regular email, just the fact a PGP encrypted message was sent by Alice to Bob would tip the authorities off that Alice and Bob were at least communicating; if they are both criminals for instance, just seeing the activity between Alice and Bob might be enough to alert the authorities to watch the pair a bit more closely because something's about to go down - even if they can't actually discover the message content.
However, if Alice and Bob are both spammers, and use the Windows worm du jour as their open spam relay, and each spam a few million email addresses, it's much harder to see that Alice and Bob are in fact conversing let alone find the actual message.

I heard "I enlarged Peter."
Intelligent Design: because MATH is HARD.
I applied this method to the lastest 100 spam mail and got the following results:
44.3% of the spammers want to get me rich, too.
32.2% want to enlarge my penis
Unbelievable! I never knew you could get 0.1% precision by analyzing a mere 100 discrete samples of email. Or does the 33rd spammer want to enlarge only 20% of your penis? Or is he only 20% sure that he wants to enlarge your entire penis?
