Cryptocurrency can be hacked
Specifically, the stolen funds included:. DeFi stands for decentralized finance, and generally refers to decentralized apps dApps built on top of smart contract-enriched blockchains — primarily the Ethereum network. These dApps can fulfill specific financial functions governed by underlying smart contracts, meaning they can execute transactions — trades, loans, etc. Without the need for centralized infrastructure or human governance, dApps can theoretically enable users to execute financial transactions at lower fees than other fintech applications or financial institutions.

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.

Bored Ape Yacht Club NFT theft shows the ease of hacking crypto
Slovenia-based cryptocurrency-mining marketplace NiceHash confirmed that its website was breached and payment system compromised, with the contents stored in its Bitcoin wallet stolen. NiceHash posted a statement on its website addressing the incident. We are currently investigating the nature of the incident and, as a result, we are stopping all operations for the next 24 hours. NiceHash allows users to buy and sell hashing power needed to mine cryptocurrency, which members can store in external or local BitGo wallets. This presents opportunities for miners, poolers, and investors alike, given cryptocurrency's increasing adoption among businesses and public organizations. Unfortunately, the increasing popularity and value of cryptocurrencies like Bitcoin also make them profitable targets for cybercriminals, as exemplified by the surge of cryptocurrency-mining malware.

North Korea hacked nearly $400M in cryptocurrency last year
Cryptocurrency and crime describes notable examples of cybercrime related to theft or the otherwise illegal acquisition of cryptocurrencies and some of the methods or security vulnerabilities commonly exploited. Cryptojacking is a form of cybercrime specific to cryptocurrencies that has been used on websites to hijack a victim's resources and use them for hashing and mining cryptocurrencies. According to blockchain analysis company Chainalysis, illicit activities like cybercrime, money laundering and terrorism financing made up only 0. There are various types of cryptocurrency wallets available, with different layers of security, including devices, software for different operating systems or browsers, and offline wallets. Novel exploits unique to blockchain transactions exist which aim to create unintended outcomes for those on the other end of a transaction.
Crypto Exchange BitMart Hacked With Losses Estimated at $196M
The company uses a decentralized finance protocol known as MonoX that lets users trade digital currency tokens without some of the requirements of traditional exchanges. Specifically, the hack used the same token as both the tokenIn and tokenOut, which are methods for exchanging the value of one token for another. MonoX updates prices after each swap by calculating new prices for both tokens. When the swap is completed, the price of tokenIn—that is, the token sent by the user—decreases and the price of tokenOut—or the token received by the user—increases. By using the same token for both tokenIn and tokenOut, the hacker greatly inflated the price of the MONO token because the updating of the tokenOut overwrote the price update of the tokenIn. Alas, it did, despite MonoX receiving three security audits this year.
Can bitcoin be hacked? All you need to know about how safe is the cryptocurrency
A smart contract is a way to handle business transactions to ensure they are secured, accurate, fast, and cost-effective—all without involving a third party, such as a bank. A smart contract uses a computer program that automatically executes the contract, the specifications of which are written into the program code. The code includes the terms of agreement between a buyer and seller, and is self-executed based on a pre-set event, such as a specific deadline. The benefits of smart contracts is that they are traceable, transparent, and irreversible. Along with the benefits of using a smart contract, there are security concerns inherent to the process.
A tweet from security analysis firm PeckShield first called attention to the alleged hack Saturday night. The hacker has been systematically using decentralized exchange DEX aggregator 1inch to swap the stolen assets for the cryptocurrency ether ETH , and using a secondary address to deposit the ETH into privacy mixer Tornado Cash thus making the hacked funds harder to track. The leader in news and information on cryptocurrency, digital assets and the future of money, CoinDesk is a media outlet that strives for the highest journalistic standards and abides by a strict set of editorial policies. CoinDesk is an independent operating subsidiary of Digital Currency Group , which invests in cryptocurrencies and blockchain startups.
So a Northwest Indiana man is headed into the holidays out thousands of dollars. Morning Insider Tim McNicholas shares a cautionary crypto tale. So I thought that was even stranger. Turns out, a hacker somehow got enough of his personal information to convince T-Mobile to switch his number to another phone.
This may have to do with two opposite trends. The stakes suddenly became higher, and indeed, a screenshot, a series of keystrokes, a USB drive, or a compromised WiFi router could lead a hacker to a veritable fortune if carried out properly. With the stakes quite high, cyber attackers have stepped up both the frequency and level of sophistication of their efforts to intervene in transactions in order to divert crypto assets away from their rightful owners. The hacker would have to breach a huge number of servers to gather information. For instance, Bitcoin and other cryptocurrencies are held in digital wallets and traded through digital currency exchanges. These wallets and exchanges are the targets of cyber attackers — not the blockchain servers themselves. Also, users and investors are most likely accessing these wallets and exchanges via mobile apps on their phones, connecting via WiFi or mobile data.
