At first, they held the tokens with an exchange based in China, but within weeks, a broad crackdown on cryptocurrency by the Chinese government meant they would soon lose access to the exchange, so they had to transfer everything to a hardware wallet.
Reich and his friend chose a Trezor One hardware wallet, set up a PIN, and then got busy with life and forgot about it. By the end of that year, the token had sunk to less than a quarter of its value, come back up, and then crashed again.
They tried guessing what they thought was a four-digit PIN it was actually five , but after each failed attempt, the wallet doubled the wait time before they could guess again. After 16 guesses, the data on the wallet would automatically erase. When they reached a dozen tries, they stopped, afraid to go further. Reich gave up and wrote off the money in his mind. He was willing to take the loss — until the price started to rise again. And with potentially millions on the line, Reich and his friend vowed to find a way inside.
The only way to own cryptocurrency on the blockchain is to have sole possession of a private key associated with a block of currency — but managing those keys has been a, sometimes high-stakes, challenge from the beginning. Hardware wallets, the size of a USB stick, are meant to solve that problem, storing the key locally, off the internet, and signing transactions inside the secure wallet when you insert the device into a computer and enter the PIN. This happens more often than you might think.
The cryptocurrency data firm Chainalysis estimates that more than 3. Currency can be lost for many reasons: the computer or phone storing a software wallet is stolen or crashes and the wallet is unrecoverable; the owner inadvertently throws their hardware wallet away; or the owner forgets their PIN or dies without passing it to family members. As the value of their inaccessible tokens rapidly rose in , Reich and his friend were desperate to crack their wallet.
They searched online until they found a conference talk from three hardware experts who discovered a way to access the key in a Trezor wallet without knowing the PIN.
The engineers declined to help them, but it gave Reich hope. Then they found a financier in Switzerland who claimed he had associates in France who could crack the wallet in a lab. It was a crazy idea with a lot of risks, but Reich and his friend were desperate. Grand is an electrical engineer and inventor who has been hacking hardware since he was Reich, an electrical engineer himself who owns a software company, had a better ability than most to assess if Grand had the skills to pull off the hack.
Then he spent three months doing research and attacking his practice wallets with various techniques. Luckily for Grand, there was previous research to guide him. A vulnerability in the wallet allowed him to put the wallet into firmware update mode and install his own unauthorized code on the device, which let him read the PIN and key where it was in RAM. But the installation of his code caused the PIN and key stored in long-term flash memory to erase, leaving only the copy in RAM.
This made it a risky technique for Grand to use; if he inadvertently erased the RAM before he could read the data, the key would be unrecoverable.
In any case, Trezor had altered its wallets since then so that the PIN and key that got copied to RAM during boot-up got erased from RAM when the device was put into firmware update mode. So Grand looked instead to the method used in the conference talk that Reich had also examined previously. They found that at some point during the firmware update mode, the PIN and key were being temporarily moved to RAM — to prevent the new firmware from writing over the PIN and key — then moved back to flash once the firmware was installed.
But by doing a fault injection attack against the chip — which affects voltage going to the microcontroller — the wallet. Because the PIN and key were moved to RAM during the firmware update and not just copied, there was only one version on the wallet during this period. As it was, each time he glitched his practice wallets, they froze.
But while trying to troubleshoot the problem, Grand stumbled on a better solution. It was a much safer solution that elegantly borrowed from both prior attacks. Reich likened the excruciating wait to sitting through a stakeout.
When the time came to do the hack for real last May, Reich flew to Portland for two days. They spent the first day getting everything set up — they filmed the hack with a professional crew — and the next day, Grand launched his script.
He immediately moved the Theta tokens out of their account and sent a percentage of the booty to Grand for his services.
It was a thrilling moment for Grand — and not just because of the money that was at stake. This includes James Howells in Wales, who inadvertently threw his hardware wallet in the trash in and lost access to Bitcoin now worth half a billion dollars.
Grand has also been speaking with someone whose wallet is on a broken phone, which would require forensic repair techniques and a couple who lost the password to a software wallet stored on their computer. Trezor already fixed part of the problem Grand exploited in later versions of its firmware. But a core issue with the chip that allows fault injection still exists and can only be fixed by the chip maker — which the maker has declined to do — or by using a more secure chip.
Rusnak says his team explored the latter, but more secure chips generally require vendors to sign an NDA, something his team opposes. This means Trezor wallets may continue to be vulnerable to other hacking techniques. Grand is already working on one new method for hacking the STM32 microcontroller used in the wallets. It will work even on wallets with the newest, more protected firmware.

There are several reasons for this; some of them belong to owners who are gone, some of them belong to Satoshi himself, but the majority of them are lost due to mistakes in money management. That's why the importance of crypto wallets increases every day, as the value of the remaining Bitcoins increases with every lost BTC. The first crypto wallet was developed by Satoshi, and it was very simple: it allowed for the generation of new addresses and sending BTC to other people. No special measures were taken to protect or recover the private key, and it was easy to type an incorrect address and send coins to the wrong destination. But these were the early days, people weren't feeling like they were losing something valuable, a few cents at best. The first exchange was launched in , called Bitcoinmarket.
