Bayesian spam filtering for the masses

Bayesian spam filtering for the masses 10/30/2003 11:59 PM
Spam, or unsolicited commercial e-mail, is now a sad part of everyday life online. Research companies estimate that more than 50% of the worldwide e-mail traffic is spam. As a result, it's becoming constantly more difficult and time-consuming to sort out legitimate e-mails from the deluge of commercial messages we're being flooded with. But there are ways to fight back. In this series, we'll walk through choosing and setting up a highly effective package for screening out spam.

Bayesian anti-spam filters count word-frequency in suspect and compare the results to profiles of word-frequency in spam and ham. Defeating this requires that your spam include a lot of natural human prose. So spammers have started to mine the Gutenberg Project and other sources of human-generated ASCII and dumping random hunks of literature into their messages to get around the filters.

Blogger and journalist Clive Thompson found an excerpt from Chapter 20 of The Master Key by Wizard of Oz author L Frank Baum in a message that had as its subject line "the big unit" (no prizes for guessing what the rest of it was hawking).

Spammer Complies With CAN-SPAM, Claims
ISPs Should Not Filter His Spam

Spammer Complies With CAN-SPAM, Claims
ISPs Should Not Filter His Spam 05/20/2004 07:05 PM
Ronnie Scelson is one of the shortlist of spammers who just seems to love publicity. While many spammers like to hide away, Scelson's always willing to talk. He testified before the Senate Commerce Committee today, claiming that he is now compl ying with CAN-SPAM, but threatened to ignore the law if not enough of his spam messages were getting through filters. He actually has the audacity to complain that now that CAN-SPAM is in effect, ISPs should be required to let his mail through. Maybe the filters are a little to thick around his head and the message isn't getting through to him: the reason his spam is filtered is because people don't want it.

Bayesian spam rumination: when
word-frequency-histograms attack!

Bayesian spam rumination: when
word-frequency-histograms attack! 06/29/2004 10:40 AM
Ed Felten has posted an intriguing rumination on the possible failure modes of Bayesian spam-filtering -- filtering that uses word-frequency statistics to classify email as spam or ham. As Ed points out, Bayesian filters are trained by the spammers, who, by choosing the vocabulary of their messages carefully, can make messages containing certain words or phrases undeliverable on the Internet.

Now suppose a big spammer wanted to poison a particular word, so that messages containing that word would be (mis)classified as spam. The spammer could sprinkle the target word throughout the word salad in his outgoing spam messages. When users classified those messages as spam, the targeted word would develop a negative score in the users' Bayesian spam filters. Later, messages with the targeted word would likely be mistaken for spam.

This attack could even be carried out against a particular targeted user. By feeding that user a steady diet of spam (or pseudo-spam) containing the target word, a malicious person could build up a highly negative score for that word in the targeted user's filter.

Personal Outgoing Spam Filter

Personal Outgoing Spam Filter 01/22/2004 02:12 AM

Most spam filters work on incoming mail.  There are some outgoing mail spam filter at mail server level, but not at the e-mail client level.  Spam filter at the e-mail client level allows the sender to avoid sending messages likely to be blocked by spam filters at the destination.

My theory is that spam filters among people with similar interests are alike.  I have no evidence to back this theory but, if true, then if my spam filter thinks a message I am about to send is a spam, then the spam filter used by the person I am sending the message to will think so as well.

Sorry to post this here, but this is a last resort. I have a customer named Curtis who purchased FeedDemon via PayPal, and he keeps emailing me asking for his registration information. Unfortunately, I've already emailed his registration information - several times.

Curtis, if you're reading this, most likely you've got a spam filter that's wrongly blocking email from the bradsoft.com domain. Please correct this problem, then contact me again so I can make sure you get your registration information. And let me know your phone number in case my next email to you bounces!

BlackHole Spam/Virus Filter 0.9.107
(Stable) released

BlackHole Spam/Virus Filter 0.9.107
(Stable) released 07/09/2002 12:52 AM
Blackhole Spam/Virus Filter provides spam and virus filtering using dot-files in all the major MTA/SMTP servers for UNIX and similar systems. It is easy for an individual user to set it up with shell account access and configure. It is different from other, similar programs, in that it executes a minimal number of programs to do the filtering, is able to use a MySQL database for the users' configuration files, can be set up as the queue in Qmail, and have virtual users' configuration files be found using the username/domain for the recipient. Multiple checks are available, and there open options on how to treat flagged email. There is logging to multiple entities, auto-expiration of flagged email, and scoring available so that multiple checks require matches that add up before blocking.

The latest poster boy for spammers is Scott Richter, who gives a fairly extensive interview with PC World where he claims, among other things that he's not a spammer, that he's making "the Internet a better place with e-mail marketing," and that he may start selling an anti-spam filter. It's funny because he continues to insist that he's not a spammer, but talks about how, without him, all those anti-spam companies would be out of business -- so they need him the way doctors need tobacco companies to keep people smoking.

For more information about Intelligent Message Filter, see Exchange Intelligent Message Filter Overview. Important: Before installing Intelligent Message Filter, you must read the Microsoft Exchange Intelligent Message Filter Deployment Guide. If you do not configure Intelligent Message Filter correctly, your messaging environment can be negatively affected.
