Title: Ledger Nano S safe?
Post by: MegUsta on September 20, 2018, 09:04:29 PM
Can a hacker/thief connect the device to another computer and read all the private keys stored on the wallet?

I think they would have to bruteforce your PIN..

Can you bypass the user interface by connecting/mounting the disk (somehow) then have access to the file system and private keys stored there?

The nano s isn't simply an USB stick. The private keys are not lying around on a flash memory.
They are stored inside a secure element.

So, no. That's not possible. You need to enter the correct pin (within 3 tries) to access the private keys.

You can read more about the ST31 secure element and the architecture of the nano s here: https://ledger.readthedocs.io/en/0/bolos/hardware_architecture.html (https://ledger.readthedocs.io/en/0/bolos/hardware_architecture.html)
