How Spammers Fool Rule-based and Signature-Based Spam Filters

The signature is added to a signature database and sent as a regular update to the email service's subscribers. He is Chief Technology Officer at CipherTrust, the industry's largest provider of enterprise email security. But as is often the case, spammers remain a step ahead and have developed more sophisticated methods for inserting random content. As a result, most spam continues to fool signature-based filters. Grandiose plans to rid the world of spam, such as charging a penny for each e-mail received or forcing servers to solve mathematical problems before delivering e-mail, have been proposed with few results.

Avoiding the Spam Trap: Get Your Message Delivered!

RSS usage and news aggregator adoption is still very limited. Over the next year or two, RSS software should improve significantly and RSS will become a more robust publishing platform.

He is Chief Technology Officer at CipherTrust, the industry's largest provider of enterprise email security. Jaynes got lists of millions of email addresses through a stolen database of America Online customers. Spammers work on the law of averages, which would seem like an odd strategy considering that the average response rate for a spam message is just one-tenth of one percent. The economics of spamming makes Jaynes' decision to build a career of it understandable, though not noble. However, once you do the math even this miniscule response rate can make one very wealthy very quickly.

BUSTED: Anti Spam Forces Bankrupt Super-Spammer Scott Richter

He is Chief Technology Officer at CipherTrust, the industry's largest provider of enterprise email security. While the bankruptcy filing shows the power of legislation and legal action from parties with a vested interest in stopping spam, Richter is not likely to fade quietly into the sunset. Despite his guilty plea, Richter maintains his innocence, saying he pleaded guilty to the felony charges because it was easier to be done with it, and he had too much stuff going on in my life. In an unrelated 2003 case, he was put on probation after pleading guilty to a felony charge of receiving stolen items worth more than $10,000. Evidently not satisfied with stealing bandwidth, Richter also shows a penchant for heavy equipment.
