A group called wallet.fail gave a presentation on how to hack cryptocurrency hardware wallets at the 35th Chaos Communication Congress. While all attack vectors required physical access, worryingly, the group demonstrated scraping the seed and PIN from Trezor RAM. So is there any way to truly protect your lovely bitcoin?
The group found ways of hacking hardware wallets via four different methods; supply chain attack, firmware vulnerability, side-chain attack, and chip-level vulnerability. All techniques required access to the actual device, so if your wallet has never left your possession…then you could still be at risk from a supply chain attack.
