Trezor hardware wallet containing $2 Million cryptos hacked

Joe Grand, a computer engineer, and a hardware hacker has succeeded to hack Daniel Reich‘s Trezor hardware wallet upon his request to recover his $2 Million worth of Theta coins saved in this Trezor Model one hardware wallet, which Daniel Reich forgot its unlocking password.

Like many other people found mining cryptos not so profitable in 2018; Daniel and his friend Jesse decided to invest and HODL a new coin at that time and they choose to buy Theta tokens paying 2 BTC, which worthed $50000 at that time at about $0.21 / Theta token.

They were storing these coins in a Chinese exchange platform, which later sent a message to all its accounts holders requesting them to withdraw any coins stored in their accounts because the Chinese government was going to shut down this exchange platform.

They bought a Trezor hardware wallet Model one and moved their coin to be stored in this device, which later they forgot its PIN code and the 24-word recovering passphrase.

The price of Theta went up from $0.21 to $14.28 in April 2021, which made their locked fortune worth more than $2 Millions.
