Actually I got some false positives on that sig yesterday. I just did a google search on the message and the 3rd or 4th link got me to arachnids. --- "Anton A. Chuvakin" <anton () chuvakin org> wrote:
Sergei and all,What does this message mean:DDoS tool shaft client (i.e. a controll program) is probably talking to one of the control modules of shaft denial-of-service network. The handlers than can send commands to DoS bots to initiate an attack.[**] DDOS shaft client to handler [**] 09/05-17:16:14.598799 213.152.133.10:80 ->217.196.100.63:20432 I suspect it is a FALSE POSITIVE. Check the signature in your /etc/snort.conf and confirm that they only track shaft by port number and not by packet content. Then the sig will trigger on RESPONSE to a web request done from high-numbered port to port 80.TCP TTL:64 TOS:0x0 ID:18426 IpLen:20 DgmLen:48 DF ***A**S* Seq: 0x82327B22 Ack: 0xBC9B5FF7 Win:0x60F4 TcpLen: 28TCP Options (4) => NOP NOP SackOK MSS: 1460Where can i read something about these signatures.Thanks a lot. Hmm, if not on snort.org/snortdb, than nowhere. Best, -- Anton A. Chuvakin, Ph.D., GCIA http://www.chuvakin.org http://www.info-secure.org
