    Mass Remote Code Injection as Googlebot - Packet Spoofing Perl bot & Trojan

    Posted by Noah Ark 11 months, 2 weeks ago.

    Filed under Security & injection.

    cat ownedFor this past three days this blog is suffering DOS attack . The attack is still alive now I don’t think they will leave yet.

    I cant banned this bot directly as they were sending forge packet (packet spoofing) as googlebot http://www.whois-search.com/whois/64.233.166.136. Im still looking for the right ISP.

    OrgName: Google Inc.
OrgID: GOGL

StateProv: CA
PostalCode: 94043
Country: US

    At the time being I blocked all remote streams from their random host *.com and “perl bot signature” but blocking will not stop them from hammering this site. I’ll be sending 503 (Service Unavailable) on certain request so if you are having problem accessing this site please check back later.

    Type of injections

    There is lot uri parameter in my logs (I will disabled server logs - limit resources) they probably has a large inventories check-lists of known CMS vulnerabilities. I can only confirm that its a blackhat seo spams bot as they request uri include the typical order.php page.

    To view the following source you need to exclude the website host from your anti-virus program.

    • Perl/ShellBot.B trojan - http://hom3.t35.com/xpl/fidz/hack/bnc.txt
    • PHP/Rst.S Trojan - http://hom3.t35.com/xpl/fidz

    htaccess blocked bad Code Injector and Perl Bot (Botnet)

    If you has similar problems. you should block the following domain in your htaccess.
    mod_setenvif

    SetEnvIfNoCase Referer "^http://(www.)?t35\.com" codeinjector_ref=1
SetEnvIfNoCase Referer "^http://(www.)?jorgevolio\.com" codeinjector_ref=1
SetEnvIfNoCase Referer "^http://(www.)?emabe\.com" codeinjector_ref=1
SetEnvIfNoCase Referer "^http://(www.)?pawang\.in" codeinjector_ref=1
SetEnvIfNoCase Referer "^http://(www.)?gw-gold\.net" codeinjector_ref=1
SetEnvIfNoCase User-Agent "^libwww-perl*" shell_bots=1
SetEnvIfNoCase User-Agent "^Amidalla*" shell_bots=1

<FilesMatch "(.*)">
Order Allow,Deny
Allow from all
Deny from env=codeinjector_ref
Deny from env=shell_bots
</FilesMatch>

    if u arent sure if you server support mod_setenvif wrap it like the below example.

    <IfModule mod_setenvif.c>
#...replace this line with the above code...
</IfModule>

    How to trap Perl Shell Bot

    We need a pattern to trap this bots. certainly we knew that these bots :

    • doesn’t honor robot.txt
    • they crawl all subdirectory
    • they has a pattern URI request

    For now I only create subdirectory for auto-ban (and some other stuff) based on their pattern. alexa bot will be banned too as they dont honor robot.txt.

    I’ll be updating this post from time to time. Do check the related articles on how to packet spoofing and validating forge/spoof packet.
