HillsCap Posted May 3, 2004 Share Posted May 3, 2004 Hi, all. I've hammered the spammers into submission so badly that I no longer receive spam in any great quantity. I've only gotten 8 over the last month, and that number is still falling. So, I had to find another method of fighting spammers. I decided to set up the JackPot SMTP teergrube / honeypot, from http://jackpot.uk.net/. This is a cool Java program... it lets a spammer's test emails be relayed, while blocking the actual spam that is sent. It also keeps a log of spammer activity, and serves that log via a built-in HTTP server. If you open a hole for that HTTP server's port through your firewall/router, you can give the URL for it to ISPs, so they can see for themselves that their users are spamming. And reporting that a user is trying to send hundreds of thousands of spams carries much more weight than reporting that you received a single spam email. Anyway, I set up JackPot about a month or so ago, but didn't get any hits on it. So, I contacted Jack Cleaver, the author of the program. He suggested that I submit my JackPot to the various websites for open relay testing, which I did. Apparently, that worked. Over the last week or so, I've been getting nibbles from spammers in Taiwan, sending test messages (which, of course, JackPot let be delivered, to trick the spammers into thinking that it was, indeed, an open relay). Yesterday, the spammers got serious, and started sending spam, which JackPot is dumping to the bit-bucket. Over the last 24 hours, I've dumped over 200,000 spam emails, mostly addressed to HotMail accounts. If everyone using SpamCop also ran JackPot, I think that would allow us to catch a lot more spammers, and it could possibly force the spammers to either quit sending spam (because the chances of getting caught goes up dramatically due to more JackPot servers running, and the spammers are wasting more of their time and resources sending to SMTP servers that then just bit-bucket the spam), or to find another method of spamming. Either way, it's a great way to slow them down. Imagine if 1000 people were running JackPot, each dumping 200,000 spams per day. That's 200,000,000 spams that don't get delivered. And it's a lot more spammers getting caught and shut down. If you haven't tried it, I highly recommend it. Link to comment Share on other sites More sharing options...
