You cannot just remove the control chipset and replace it. In most cases, if you enter the password incorrectly a number of times, the control chipset will initiate the entire flash memory being overwritten. You therefore cannot take a physical image or start to try to brute force encrytion. The removable storage device component of the U3 is not accessible by the host and does not even appear on the bus until this security mechanism allows it. When security is implemented in these devices, only the CD-ROM device and CDFS are presented to the file system where some software resides controlling access to the removable storage device. Encryption aside (which is another issue) in U3 devices, as discussed, the controller presents itself to the host as two separate devices, a CD-ROM device and a removable storage device. In a USB thumb drive you esentially have a controller chipset and flash memory. So i decided to use hardware solution and i got this ,

I work with a company for security and forensics, so the court send us a USB protected with password ( sandisk USB ) i try to use some software methods to bypass the password work's with v1 and v2 only they didn't work with U3 DĪnd i cant lunch brute force attack Because of the self-destruct feature ]
