Welcome back guys
In this article we will talk about USB U3 hack which is getting popular among most hackers and computer geeks.
As we all know that one of the easiest way into a system is by using USB flash drive that implements the U3 standard.

What USB U3 Hacking means?

U3 system is a secondary partition included in USB flash drives. made by SanDisk.
The U3 partition is stored on USB flash drives as read only and it often contains free software for users to try or download.
U3 partition menu is configured to execute automatically when the USB stick is inserted into certain computers.
The U3 hack works by taking advantage of the autorun feature built into windows.
When USB is inserted into the computer, the USB flash drive is enumerated, and two separate devices are mounted .One of them is U3 partition of flash drive and other is regular flash storage device. The U3 partition of flash drive immediately runs whatever program is configured in the autorun.ini file on the partition. Device manufacturer also provides a tool to replace the U3 partition with a custom ISO file for branding or deleting the partition.
Hackers use manufacturer's tool to include a malicious program that executes in context of currently logged-on user.
The most popular attacks done by hackers is to read password hash and to install torjan for remote access the system.
Hacker can also include a program to receive password hash file using email or can store password hash file for offline cracking using tools like-- fgdump.
Hackers use - U3 customizer tool to customize U3 partition of flash drives.
So please be careful next time you insert a flash drive into your system.
I will recommend to disable autorun feature in windows.
