Unciphered, a cybersecurity company, recently claimed in a YouTube video that it hacked the T model of crypto hardware wallet manufacturer Trezor.
In its video, the company shows that after performing various operations on the cold wallet, it can access both the PIN code and the wallet keywords called seed phrases.
This isn't the first time Unciphered has managed to extract seed phrases from hardware wallets. In February, the company carried out a similar attack on a wallet made by Hong Kong-based OneKey.
Hardware wallets that store private keys offline and are designed to protect crypto assets are generally considered highly secure. However, Unciphered said that the hardware security mechanisms of the Trezor T model could theoretically be bypassed if a hacker had a T wallet in their hands.
The Unciphered team said in the video that they have developed an "internal exploit" that allows them to extract the wallet's firmware. Eric Michaud, co-founder of Unciphered, claimed that they were finally able to crack the device's pin seed phrase by utilizing custom GPU chips.
“We uploaded the extracted firmware to our high-performance hack clusters,” Michaud said in the video.
"We have about 10 GPUs and after a while we were able to extract the keys."
