Spam Research Six Month Report

Zoomer writes "Every day, millions of people receive dozens of unsolicited commercial e-mails (UCE), known popularly as 'spam.' Some users see spam as a minor annoyance, while others are so overwhelmed with spam that they are forced to switch e-mail addresses. This has led many Internet users to wonder: How did these people get my e-mail address? In the summer of 2002, CDT embarked on a project to attempt to determine the source of spam. To do so, we set up hundreds of different e-mail addresses, used them for a single purpose, and then waited six months to see what kind of mail those addresses were receiving. The results offer Internet users insights about what online behavior results in the most spam. The results also debunk some of the myths about spam." Update: 04/12 15:47 GMT by CN : About a minute after this went live, I found that michael posted this earlier. Mea culpa.

  58. Not all means taken into "account" by Kaz+Riprock · · Score: 3, Interesting


    Just having an account can get you spam these days. Even at a university...especially at a university. Like any good system, my school's mail/student server is organized by year and/or alphabetized.

    If any user changes up a directory...does an ls -1p > spamlist.txt and then mails said spamlist.txt to their friendly neighborhood spammer who pays them 20$...then all of those users just got added to somebody's hit parade, even if they never submitted their address to a public or private outlet.

    I know this, because my email address is a bit ambiguous. One could email me at fake@university.edu or fake@xxx.university.edu and it would arrive in my mailbox. I have *NEVER* used this email address in any forum other than work-related issues and have *NEVER* used the "xxx" portion of the email when I have submitted it (in interest of brevity).

    I currently procmail filter about a dozen different spammers (each sending different revisionary mails of each of their products) and invariably the address used is fake@xxx.university.edu (NOT the one I have ever used). Clearly someone determined what my account was named and then determined the mail server to be xxx.university.edu and put the two together. It's easy enough if you have an account on the server to simply list the home directories into a file and submit.

    fake@xxx.university.edu is not listed on any google-indexed site or usenet article which furthers my belief that this came from within. Also, some spammers send the mails to about 15-20 university accounts at a time (they don't always hide the headers correctly and I get a cc list of about a dozen other users on my university's student server...ALL using xxx.university.edu).

    These inside jobs are easy, do not negatively affect the committed party (unless the school is logging every ls command), and probably earn you enough money to buy a six-pack. A few beers for the inconvenience of your fellow students...great job, jerky.

    I have suspected for some time that lots of spam gets sent to people who send (or recive) lots of forwards. This is the only explaination I can think of for some of the spam I've seen to some "private" (given only to friends) addresses. This implies, I suppose, that some friends, or friends of friends, or their friends are giving my address to spammers.

    They also didn't test viruses as a method of address-harvesting. (Viruses like Klez that send mail to random people with forged From: addresses.) I have no clue how much spam comes from this, but it would be very interesting to know.

    I note also that this study didn't include any control to compare results to "real" addresses that get used for lots of things, so maybe there is some other method that spammers use, that also wasn't tracked. Six months might be too short of a time. I know I get mail to new@walt (walt is a machine that had a usenet server on it during the mid-ninteties), so old email addresses, once harvested, get on CDROMS and keep getting hit forever.
