Bombarded by shared directories list requests
« on: January 23, 2006, 06:29:41 PM »
Since 11:07, I have been under repeated barrage by a user named "stima" requesting my shared directories list. I have logged more than 3200 such requests since this morning, usually in bursts of up to three per second, like this:

This user appears in the log under several client IDs, namely 2027979934, 803308702, 2011268254, and 3084944542.

I am getting REALLY tired of it, since it slows down my system -- CPU usage goes way up. Anyone have any idea of what is going on? Is this a rogue eMule client or some kind of DoS attack? FWIW, I have the "Filter incoming messages" option switch on.

Anyone else seen anything like this?

well, stima is at it again. Since posting the above, I have received more than 21,000 requests between the hours of 23:34:59 and 1300 (now), and they continue. I ran ethereal and got his IP number,  158.132.224.171, which resolves to a university in Hong Kong: ppp224171.its.polyu.edu.hk

Now, what to do about it...

You can always put him in your ipfilter list, since you know the IDs.

He appears to be using a pool of IP numbers, hence the periodic changes in his client ID. I've blocked this range:158.132.224.145 - 158.132.225.255 . So far, so good.
