RE: How To Hack A Trezor or KeepKey Hardware Bitcoin Wallet - Plus Make Your Own Open Sourced Hardware Wallet!
can you summarize how the Trezor can be corrupted/hacked?
I recently purchased one for security reasons so I'm very interested in knowing bout any vulnerabilities.
As I understand from the presentation at Defcon, the main method of attack they demonstrated involved a process of using a specifically designed piece of hardware to manipulate the voltage of the Trezor unit in such a way that it could be caused to process information incorrectly inside it's circuits. When this is done in combination with specialist analysis software it is apparently possible to eventually figure out what the pin code is for the device and to thus then use the cryptocurrency that is held on it.
Clearly this is a highly specialised and 'cutting edge' type of attack that is not going to be easy to pull off - but once these things become more widely known about, they spread and it may become relatively simple to hack older units that have not been adjusted to defend against this kind of manipulation.
