Team,

If you recall an email I sent on 2008.03.07 with the Subject:

UDP based DDoS attack against 80.65.160.10 (AS21196)

Tim and Rob came back with the following:

At least some of the attacks were launched from a combination Windows
and Unix botnet.  The botnet is located on the #rlz channel on
64.32.10.177 TCP 6667.  We see 37 bots on the attack channel presently.
 The miscreant or crew is labeled as "jebac" (no quotes).  We don't
generally bots of different OS combined in one channel, so this is
fairly rare:

#rlz       [A]UDP48264971 H
~UDP572351 at UDPLink-CFECB7CA.operating-networks.de (Linux
operatingcust01.operating-networks.de 2.4.21)
#rlz       [C]UDP37410253 H   ~UDP929979 at UDPLink-8009F69E.skypoint.net
(FreeBSD matthew.skypoint.net 4.5-RELEASE FreeBSD 4)
#rlz       [A]UDP46308402 H   ~UDP647385 at 67D107C.4C4F7FB1.4A809331.IP
(Windows NT LAB223SERVER 5.2 build 3790)
#rlz       [A]UDP82437591 H   ~UDP911187 at 76395417.B3290689.E4654BAC.IP
(SunOS omega 5.8 Generic_108528-24 sun4u)
[ ... ]

Some of the attack commands are listed here.  All dates and times are
UTC/GMT.

2008-03-07 09:12:59  [#rlz] <A>  .udpflood 80.65.160.10 65000 120
2008-03-07 09:23:12  [#rlz] <A>  .udpflood 80.65.160.10 999999 20
2008-03-07 09:23:22  [#rlz] <A>  .udpflood 80.65.160.10 999999 20
2008-03-07 09:23:24  [#rlz] <A>  .udpflood 80.65.160.10 999999 20

- ---------------------

Not sure if the botnet still resides at the above, but the DDoS (with
corresponding blackmail email is back - gmail addy). Details are as follows:
