GeneralBrute force e-mail harvestors Pin

Some of you may remember those Hotmail spam tests I did much earlier in the year, where I created two new accounts, one with a five digit name (but totally random, like g9k1d) and another 32 digits long (i.e. j7sd64we4gw4w43...), to see if any got sent any spam. I didn't dvertise either addresses anywhere but still the 5 digit long account was hit with a load of spam. From this it seemed fairly likely that people were running bots against known e-mail domains to harvest valid (non-bouncing) e-mail addresses, and then added them to various lists. We can only hope that the mail server programmers catch on to this and implement artificial intelligence rules to guard against this sort of thing in the future.

Well tonight I had a big scare. I received about seven million blank e-mail messages sent to a domain I control all sporting a different "To:" address. a, b, c, d, etc, right through to the final one before I got the "catch all" pop3 account shut down of d6l1r. (read about my big scare here). To me this seems pretty obviously a brute force attack to gain valid e-mail addresses or some script kiddie bombing me.

[ edit: it seems that only 24,000 or so messages actaully made it through, the rest were bounced as the space limit on the pop3 account was filling up too quickly ]

I can recall receiving one of these mysterious blank messages to my main e-mail account (dwulff@mydomain.com) about a week ago - was this used to probe the domain and schedule it for a future brute force scan? The similarities of the messages are too much of a coincidence to me, so I am warning anyone who gets what appears to be an innocent blank e-mail (and you'll find the headers - apart from "To:" unlike I originally thought - to be missing) to immeadiately check, double check and tripple check that you do not have a catch-all e-mail account. Whislt they can be very useful (and important) it looks like the spammers have caught onto using them as an easy way to increase their lists (though why is beyond me, they acheive nothing through it Confused | :confused: ). I shudder at the thought I may now have tens of thousands of e-mail addresses floating round on some spam list somewhere.

Could it be time to push American's out of the top three positions on David's Pet Hate list and fianlly add spammers to the number one slot? Unsure | :~
