Mar 26, '16

Long time no see. First post on english, let's start. Today special is pwning the old carding shop called "electronicpromo". Electronicpromo allows various carder from around the world to check credit card balance, additional check if credit card is valid and working, check for VBV (Verified by Visa) & MCSC (Mastercard Secure Code) etc. We will cover all of them later but first.. Let take a small look at information of Electronicpromo.

I Gathering info Electronicpromo

Website     :
IP          :
Name servers: ;
Mail server :


Domain is registered @ You can check whole whois at Particular thing I found very interesting is registration and creation date of domain which is 01/05/2010. Seems that either domain administrator don't have a life, or lives in a country which doesn't celebrate (International) Workers' Day [1]. Just to note that whois registration info is private, either by private-whois or another offshore service.

First step is to dig inside of domain name, check behaviour and such. Lets start!

$ dig +noadflag

At the time of writting this document, we've checked IP address to which we access domain. Based upon our research we've found that IP address with numbers is dedicated from datacenter located in USA. Owner of this IP is Black Lotus Communications[2] company (BLCC) who provide DDoS protection.

This kind of reference give us clue to ask same company for additional information of their client who need this service. In this case Black Lotus provide emergency response center telephone number but I was kind enough to contact abuse center by e-mail. Black Lotus will be forced to reveal information so we can sinkhole domain and do additional tracking of administration.

Location of IP address by map/graph:

Lets keep smashing the box. While doing the vulnerability assestment on Electronicpromo, I've found out that they have "_vti_inf" file which reveals us that FrontPage is installed, and that we can check FrontPage Configuration Information. Looking up into this file, comments reveals us this:

Frontpage Version       -
Frontpage SHTML Script URL  -   _vti_bin/shtml.exe/_vti_rpc
Frontpage Author Script URL -   _vti_bin/_vti_aut/author.exe
Frontpage Admin Script URL  -   _vti_bin/_vti_adm/admin.exe

Without too much complication of process we use, here are the relative informations. Oh yes, by the way, thanks for setting file_uploads register to 1 (On)! Gived us much, much help.

$ uname -a
Linux 2.6.32-358.2.1.el6.x86_64 #1 SMP Wed Mar 13 00:26:49 UTC 2013 x86_64

$ mysql --version
mysql  Ver xx.xx Distrib 5.1.73 (masked*)

$ openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013

Definitely my box.

$ php -r "print getenv("DOCUMENT_ROOT")";

$ php -r "print getenv("SERVER_ADMIN")";
