So I recently ordered a chinese external USB card and I would like to find out whether it has some hidden functionality, which might become malicious. It has buttons integrated in it so Linux using
libusb -vv displays it of having HID capabilities, which already alerted me since it could be used to inject keystrokes.
- How do I go on continuing my analysis?
- Can I dump more information about its capabilities using libusb?
- How do I dump its firmware for reverse engineering purposes? According to [this] that's only possible with a JTAG/UART connection?
- Is there something like Wireshark but for USB?
Bonus points if you also add some libusb example code.
