Saturday, 02 July 2005
An e-mail or word processing document that contains active code intended to cause damage to the recipients computer such as erasing the hard disk. See macro virus and mail bomb.

mail bomb

A huge number of e-mail messages sent to one destination or an e-mail with an extremely large attached file. Mail bombs are sent to antagonize their recipients and/or to cause them problems by filling up their disks and overloading the system. See spam and letter bomb.

spam

E-mail that is not requested. Also known as "unsolicited commercial e-mail" (UCE), "unsolicited bulk e-mail" (UBE), "gray mail" and just plain "junk mail," the term is both a noun (the e-mail message) and a verb (to send it). Spam is used to advertise products or to broadcast some political or social commentary.

A Social Plague
Like viruses, spam has become a scourge on the Internet as hundreds of millions of unwanted messages are transmitted daily to almost every e-mail recipient as well as to newsgroups. Unfortunately for users and fortunately for spammers, as an advertising medium, spam does produce results. Even if only an infinitesimal number of users reply, it is still cost effective since e-mail is a very inexpensive way to reach people.

ISPs Work Overtime
In order to alleviate some spam, ISPs have added an enormous number of servers doing nothing more than spam filtering (see spam filter). The CAN-SPAM act in the U.S. became law on January 1, 2004, which provides severe penalties for spammers, if they can be located (see CAN-SPAM). See spim, mail bomb, Joe Job, SPF, letter bomb, spamdexing, Blacklist of Internet Advertisers, munging, RBL, ROKSO, MAPS, spam relay, spam trap, botnet, rogue site and opt-in.

Why Do They Do It?
Simple math. Suppose that out of 2,000 spam messages, one person clicks the link, and the spammer makes $1. If a million spams were sent that day, the spammer made $500, and the job might have taken a half hour to set up. That means only a few hours per week could yield $100,000 a year. Is that incentive enough for high-school students, or would they rather go back to their paper routes? Of course, consistent revenues are not guaranteed, but some spammers make a whole lot more than $100,000 every year. In any case, there is ample motivation.

Spam Filters Create More Spam
As spam filtering becomes more sophisticated, spammers have to send even more spam to make the same money, but e-mail lists can be purchased for very little or hijacked. There is a thriving business selling e-mail lists to spammers as well as lists of compromised computers (see zombie). There are even third-party spam service providers that will do all the work for you.

Easy to Rationalize
Spammers justify their existence by citing the enormous amount of unsolicited ads we get via the postal system, which wastes trees and other resources. They claim advertisers pollute the environment every day with obnoxious ads on TV, radio, buses and billboards. Of course, they have a point, especially regarding the tons of paper thrown in the "real" trash can every day. However, none of these other approaches threaten to close down the system they live in.


From the Horses Mouth This book was written by a spammer, known only to readers as "Spammer-X." For insights into the minds of real people who spam for a living and explanations of how they do it, read "Inside the SPAM Cartel." (Syngress, 2004, ISBN 1-932266-86-0)
