Researchers from Kraken say they could have access to Trezor One and T wallet keys by manipulating the voltage in the microcontroller. These hardware components contain important information, such as seedy. This vulnerability has been known for some time and has also been discovered in other hardware wallets. However, an attacker needs physical access to the device to exploit this error, which limits the severity of the threat. Overall, Kraken's team said data theft took about 15 minutes. Trezor's team is aware of this problem, however, and quickly published a response to Kraken's discovery. Although this is not the first vulnerability detected in the company's devices, its removal will probably require a complete redesign of the equipment.

How to store cryptocurrencies securely?

As you can see, secure storage of cryptocurrencies is still a challenge. Hardware wallets are considered one of the safest ways. It is also worth thinking about paper wallets. The basic rule is that funds are not kept on stock exchanges, which is confirmed by subsequent collapse of stock exchanges from this market. Cryptocurrency storage services that offer platforms such as Baakt and Gemini may be a new solution. We are talking here about reliable companies that offer insurance against the loss of digital currencies and are subject to independent audits to ensure the correct handling of assets. Nevertheless, these services cost and often quite a lot. In addition, they reject some purists. Trezor has enjoyed a good reputation on the market so far. His equipment is of high quality. And this despite the recently discovered vulnerability, which will probably be removed. It is also worth noting that there are no known cases of cryptocurrency theft due to the use of hardware wallet defects. In addition, the vast majority of theft of funds is due to user error. Remember that there are slightly different rules in this market. You are responsible for your digital coins, so you must ensure the security of the private key, password and file that gives us access to our wallet.
