Alvin told me it might be good to forward it to INCIDENTS. There are my comments on the binaries of this rootkit I got from him - you might want to check if you have one already ;-): - The rootkit itself is called 'ManiaC r00tkit' (how pathetic). We were not able to find it anywhere on the net (searching for filenames and such), so I presume it is pretty new, - It consists of a sniffer, few trivial backdoors, DoS tools, bnc IRC bouncer, setuid shell and so on. It uses Ava/Adore kernel module to hide itself, and replaces few binaries, modifies one rc script - it is not too advanced, - Rootkit installation script: echo "Copiando os arquivos necess.rios." This sounds like Portuguese or so, which probably tells us about its origins. - It removes few patterns from logfiles. That would be: 200.195.86.*, 200.248.162.*, 200.195.121.*, 200.243.17.*, netdados.com.br, usinet.com.br - I presume these are networks attacker used for defacements (how smart to put them in the script in this form!), - It sends information about machine to tuiqoitu039t09q3 () bigfoot com, bnadfjg9023 () hotmail com, t391u9t0qit () end-war com, mki62969o () yahoo com. One of these mailboxes is still working (bigfoot.com, others are provided as a decay or so), - pt07 and mailrc binaries are backdoors. Listening on 56789/tcp, with password "include.h", it hides under the name of "klogd": Trying 0.0.0.0... Connected to 0. Escape character is '^]'. include.h Bem Vindo MaNiAc 31337 a sua makina! Voce Tem o controle! =) bash: no job control in this shell bash-2.01#
Once again, I haven't seen any mention of this backdoor port anywhere. Hope that helps,
