How Spammers Get Email Addresses

How Spammers Get Addresses ? There are so many companies which sell CDs with plenty of valid e-mail addresses. With MS Word, you'd easily make those addresses into lines of 100 addresses each, and then cut and paste those lines in the "To:" field of any e-mail program.The problem with spam is, incredibly easy to send. Practically costs nothing to send it. Reply rate is also very less 1 is to 1000 ratio of e-mails, Where does a company get millions of valid e-mail addresses to put on a CD and sell to you? There are a number of primary sources.

newsgroups & chat rooms, Newbies often provide their screen names, or keep valid e-mail addresses, in newsgroups. Spammers do use a software to extract the screen names and e-mail addresses automatically.

The Web itself. There are thousands of Web sites, The programs that do the spidering is spambots, searchs the Web specifically looking for "@" sign that indicates an e-mail address.

Websites created ONLY to attract e-mail addresses. Just like, a spammer creates a site that says, "Win £1 million!!!, ONLY type your e-mail address here!" In the past, lots of large sites also sold the e-mail addresses of their members. Or the sites created "opt-in" e-mail lists by asking, "Would you like to receive e-mail newsletters from our partners?" If you answered yes, your address was then sold to a spammer.

Probably the most common source of e-mail addresses, however, is a "dictionary" search of the e-mail servers of large e-mail hosting companies like MSN, AOL or Hotmail. In the article Hotmail: A Spammer's Paradise?, the author describes the process:
A dictionary attack utilizes software that opens a connection to the target mail server and then rapidly submits millions of random e-mail addresses. Multiple adresses have slight variations, such as "" and "" The software then checks which addresses are "live," and adds those addresses to the spammer's list. These lists are typically resold to many other spammers. E-mail addresses generally are not private. Once a spammer gets a hold of your e-mail address and starts sharing it with other spammers, you are likely to get a lot of spam.

So keep in might, You are not safe and secured in this Virtual world!!!
