Spam From Idiots
am 09.05.2006 23:22:33 von Alan Connor
I have a mailbox reserved for spam, where the headers are
stored for possible future study.
wahoo77@yahoo.com
Been noticing a lot of subjects like this:
Subject: aardvark test oceans mega...
Subject: So she walked to the corn...
Subject: slimy athabasca never lov...
Subject: On This Fine Winter Day S...
Subject: generous outage if and th...
Subject: yellow first Commonwealth...
If I ever saw those subjects, or anything like them, in my
real mailboxes, I'd dump them without a second thought.
And I find it hard to believe that _anyone_ would even bother
opening them.
I think the spammers are like the idiot trolls: They just aren't
paying attention and don't notice that no one is reading their
crap. Especially their targets, whom they imagine that they
are devastating, I'm sure.
They spam and spam and spam and never make a cent, and can't
figure out why.
Clue: If a mail looks like it was sent by an inmate at a
mental hospital, 99.9% of the people that receive it are
going to dump it without opening it.
And the other .1% doesn't have enough money to buy anything.
[Note: I don't read the articles of "Sam" or his numerous
sockpuppets or his 'friends', nor any responses to them, and
haven't for years. He follows me all over the Usenet, and I
still don't read his articles. This _really_ pisses him off.

Me too. But you just got me thinking about my SpamAssassin bayesian
training.

I think the above type of emails, at least the ones I have been getting
where the body is just a bunch of random phrases, are meant to throw off
learning/training type spam filters like bayesian ones.
I'm pretty sure you don't use SA, and I know you use a C/R system, but
please indulge me.
Those emails themselves are not spam (at least by my definition since
they are not selling anything, although they are certainly unsolicited
bulk emails).
So my question is this - should I pass those type of emails on to SA's
bayesian training system, or just delete them?

No, he doesn't. Beavis makes a lot of noise about C/R, but in
http://tinyurl.com/rvvsd he lets the poor, suffering cat out of the bag:

That's the best testament as to the effectiveness of a C/R system.

I wasn't asking him directly. I would've emailed him for that.
I posted on USENET which is a public forum. Yes I know some of the
phrases I posted referred to "his" system etc, but anyone can
read and followup here as you have done.
I was hoping for someone with some knowledge about bayesian systems to
reply. That's why I changed the subject heading. In hindsight maybe I
should've started a new thread but I got lazy.
Do you know anything about bayesian training in relation to my question?
> See the AC FAQ that's regularly posted to this newsfroup.
I haven't seen those deliberately provocative and antagonistic posts of
yours for some time since they have nothing to do with this group.

If SpamAssasin is automatically learned them as non-spam ('ham'), then
at least you want learn them to spamassasin as spam.

They are not learned as ham. I have passed them to sa-learn as spam to
date, but I am not sure I should be doing this. They are not really
spam, they are just random phrases/words set to throw off spam trainers.

SpamAssasin learns also from mail headers, so it is still possiblity that
SpamAsasin learns something usefull.

That has never stopped me from using those to train a bayesian filter.
It can bloat the bayesian database eventually if you have it learn every
single spam or ham message but that's about it. Feed enough of them to
the filter so that SA correctly identifies them as spam, after that have
it learn more only as needed to keep the bayesian filter updated.
Bayesian systems look at headers separately from the body of the
messages. So there are things in the headers that a bayesian filter can
use that are independent of the contents of the message body.
I use bogofilter myself which can be gotten from bogofilter.sourceforge.net
There is a pretty good FAQ there on how bayesian filters work.

Couldn't tell you, Troy, but someone will.
My hunch would be to delete them. If they are sent to throw off
your filter, why give them a chance?

I should note that a lot of C/R users _do_ use SA as the
conventional spam filter stage in their Challenge-Response
system:
http://home.earthlink.net/~alanconnor/elrav1/cr.html
The 'graymail' gets the challenge.
It's very easy, as you well know, to use procmail to pipe
non-passlisted mail through SA and return it to procmail, scored
by SA, for the C/R stage, with everything but the 'graymail'
dumped by a simple recipe.
I prefer a straightforward procmail ruleset for that
stage.

It depends on the individual implementation.
Although something may seem random to you, there are patterns even to random
number generators.
A smart bayesian filter might pick up on the fact these spams -- for example
-- consist of two MIME sections, the text/html section containing a single
with an inside it that references a CID: of the second,
image/gif MIME section; as I suspect you'll find many of these spams
contain.
You can't really answer this without knowing the particulars of the bayesian
implementation.
