The experts admit: when handling the wallet, nothing felt suspicious, as all the functions worked as they should. However, when launched, the wallet showed that bootloader’s version was 2.0.4, which was never actually released due to security reasons.
Later, the analysts found that the housing of the fake version was held with liberal quantities of glue and double-sided adhesive tape instead of the ultrasonic bonding. Moreover, inside the device there was an “entirely different microcontroller showing traces of soldering,” the experts added.

Hence, instead of the original STM32F427, the fake crypto wallet had an STM32F429 with fully deactivated microcontroller flash-memory read-out protection mechanisms.
Analysts say the fake version allowed scammers to steal over 1.3 BTC even though the wallet wasn’t connected to the Internet at the moment of the incident. This might be due to the fact that the device instead of generating a random seed phrase selected one of the 20 pre-generated seed phrases made by scammers.
