Building on its reputation as a leader in anti-spam technologies, Wizard IT is nowoffering the public these anti-spam tools for free through the SpamRatswebsite(www.SpamRats. com) and through MagicMail, a product offering from its sistercompany LinuxMagic. The tools provided on the SpamRats website are designed to beused use by anyone and on almost any email server.
Michael Peddemors, President/CEO of Wizard IT, strongly believes that stopping thesender is better than trying to filter what they send. He says that the use of IPReputation is one of the most effective ways for Internet service providers toreduce overhead, bandwidth, and the amount of Unwanted Bulk Email (UBE) received.
"It is a 'Zero Day' protection approach that is needed to stop the millions ofTrojans and Bots that send spam or attack servers. People need to be protectedagainst new and unknown threats before the vulnerability is discovered andexploited, said Mr. Peddemors. He added, we have seen the progression of howSpammers have tried to get around filters. At first there were plain text spammessages, then it was spam in attachments, after it was spam hidden in images, thenit was in PDF's, and now we see Spam in WAV audio and voice messages. Spammers willalways try to get around the filters because there is so much money to be made, butif you can stop the connection at the point when you determine it likely to be aninfected PC or a spam engine, then you get 'Zero Day' protection. If you know whatis going to be sent to you is infected or abusive, filtering technology 'should not'be your first line of defence.
Based on statistics, Wizard IT has found that the most abusive types of connectionsare those that either run dictionary attacks, or mass mailings that usually conformto the following four types:Botnet/Spammers from IP's with no Reverse DNS Botnet/Spammers from infected PC's (Dynamic or Generic Reverse DNS) Email Marketing Companies Compromised Servers The list that are available for public use include:
RATS-Dyna - RATS-Dyna is a collection of IP Addresses that have been found sendingan abusive amount of connections or trying too many invalid users at ISP and Telco'smail servers. They are also known to conform to a naming convention that isindicative of a home connection or dynamic address space.
RATS-NoPtr - RATS-NoPtr is a collection of IP Addresses that have been found sendingan abusive amount of connections or trying too many invalid users at ISP and Telco'smail servers. They are also known to have no reverse DNS, a technique often used bybots and spammers. Email servers should always have reverse DNS entries.
