BadUSB hacker USB flash drive

Some viruses modify the firmware of a USB device to trick the operating system into detecting the USB device as a keyboard. As a result, viruses may execute commands under your user account to download malware, etc.
The BadUSB Attack protection component prevents infected keyboard-analog USB devices from connecting to a computer.
When a USB device is connected to a computer and recognized by the operating system as a keyboard, the application prompts the user to enter a numeric code generated by the application from the keyboard or to use the on-screen keyboard. This process is called keyboard authorization.
If the code is entered correctly, the application saves the identification parameters -- the VID/PID of the keyboard and the port number it is connected to -- in the authorized keyboard list. After reconnecting the keyboard or restarting the operating system, you do not need to repeat keyboard authorization.
In Badusb, we can write to a variety of shells to perform any operation you want.
