History of Mt. Gox

Launched in 2010 by American programmer Jed McCaleb (who later went on to found Ripple and Stellar), Mt Gox has expanded rapidly to become the world’s most popular bitcoin exchange after being purchased by Bitcoinist. French developer Mark Karpelés in March 2011. Oddly enough, the name Mt Gox stands for Magic: Online Electronic Transactions. ( Magic: The Gathering Online eXchange ).

In June 2011, the exchange Mt. Gox was hacked, most likely the result of a compromised computer by a corporate auditor. On that occasion, the hacker used their access to the exchange to artificially change the nominal value of bitcoins into a penny and then transferred around 2,000 bitcoins from customers’ accounts on the exchange. , then sold. Additionally, an estimated 650 bitcoins were purchased from the exchange at an artificially low price by Mt.Gox.

After the hack of Mt. Gox has implemented a number of security measures, including arranging for a significant amount of its bitcoins to be taken offline and kept in cold storage.

Despite the June 2011 hack, in 2013 Mt. Gox has become the largest bitcoin exchange in the world, in part due to increased interest in bitcoin as the prices of these coins rapidly increased (jumped from $13 in January 2013 to a peak of over 1,200 dollars).

However, behind the scenes all is not well.

The struggle behind the scenes

Although Mt. Gox rapidly expanded to become the largest bitcoin exchange in the world in 2013, behind the scenes it was struggling. Since the collapse, some employees of Mt. Gox talked about how Mt. Gox is up and running, as a picture painted by a disorganized and discordant group, with poor security procedures, serious problems with the website’s source code, and some serious problems. related to business activities.

In May 2013, a former business partner of Mt. Gox is Coinlab sued the company for $75 million, claiming breach of contract. The two companies have signed an agreement under which Coinlab will take over the US client of Mt. Gox, but according to Coinlab’s lawsuit, the deal did not materialize due to Mt. Gox violated a term of the contract.

Additionally, the US Department of Homeland Security is investigating claims that a subsidiary of Mt. Gox operating in the US is not licensed and therefore acts as an unregistered money transmitter. As a result of this investigation, more than $5 million was seized by the US government from the company’s bank account.

According to the results of the US investigation, Mt. Gox has announced the temporary suspension of withdrawals in US dollars. Although this suspension only lasted for a month, many customers experienced delays of up to 3 months in withdrawing funds from their accounts and several US dollar withdrawals were successful. These delays lead to Mt. Gox lost its position as the largest bitcoin exchange in the world at the end of 2013, falling to third place.

However, as it turned out, these problems are the tip of the iceberg. Underneath the hood, Mt. Gox had much bigger problems than it realized. It has been the victim of an ongoing hack for more than two years.

The hack of Mt. How does Gox play out?

On February 7, 2014, Mt. Gox has halted all bitcoin withdrawals, claiming that it was only halting withdrawal requests to get a clear technical view of the monetary process. After a few weeks of uncertainty, on February 24, 2014, the exchange was shut down. That same week, a leaked corporate document claimed that the hacker raided Mt. Gox and stole 744,408 bitcoins belonging to Mt. Gox, and 100,000 bitcoins belonged to the company, resulting in the exchange declaring it insolvent. On February 28, Gox filed for bankruptcy protection in Japan and in the US two weeks later.

Subsequent investigations have shown that the massive hack of Mt. Gox started as early as September 2011. As a result, Mt. Gox operated while insolvent for nearly two years and lost practically all of its bitcoins in mid-2013. Additional evidence has shown that Mt. Gox was missing up to 80,000 bitcoins from its exchange even before Mark Karpelés bought the exchange in 2011.

While it is still an ongoing investigation and the facts are still unclear at this point, most probably the bitcoins that were stolen from Mt. Gox was pulled from its online (hot wallet) wallet, which includes all the currencies being held in cold storage, due to a “leak” in the hot wallet. An online cryptocurrency wallet is a web-based wallet that is used to securely store digital codes, known as private keys, which represent ownership of a public digital code, known as a public key. can be used to access the currency address and it is this information that is stored in the wallet. Prior to September 2011, the private key of Mt. Gox is unencrypted and it looks like it was stolen via a copied Wallet.dat file, by hacking or possibly through insiders.

Once the file has been hacked, the hackers can access and encrypt bitcoins incrementally from wallets associated with the private key of Mt. Gox without being hacked. The shared keypool of the copied file resulted in reuse, which meant that the company appeared to be oblivious to the theft, with Mt. Gox interprets transfers as deposits appear to be moving to more secure addresses. Whenever the wallet is empty, the Mt Gox system accounts for theft as deposits result in an additional 40,000 bitcoins being credited to multiple user accounts.

The aftermath of the Mt. Gox

In March 2014, Mt. Gox reported on its website that it found 200,000 bitcoins in an old format digital wallet that was used by the exchange before June 2011. These bitcoins are still trusted by creditors while The company is still under bankruptcy protection.

Mark Karpelés was arrested in Japan in August 2015 and charged with fraud and embezzlement, although no charges were directly related to the theft. He was imprisoned until July 2016, and was released on bail. He has pleaded not guilty and his trials are still ongoing.

MT. Gox is still under bankruptcy protection, with the case still under investigation. In addition, the lawsuit with CoinLab remains backlogged and distribution to creditors is likely until the lawsuit is resolved.

Where did the Bitcoin hack money go?

650,000 bitcoins are yet to be counted as a result of the Mt. Gox . Some have suggested that Mt. Gox never had the amount of money it claimed, and Karpelés manipulated the numbers to make Mt. Gox holds more bitcoins than it actually does.

Regarding how hackers can access bitcoins that Mt. Gox kept in cold storage, theories range from suggestions that storage may have been compromised by an individual with onsite access to suggestions that cold storage coins have been gradually deposited into the Mt trading system. Gox when a hot wallet is running low, and the lack of accountability among staff simply means there is no awareness that the wallet has been drained by the hacker.

In July 2017, a Russian citizen named Alexander Vinnik was arrested by US authorities in Greece and charged with playing a key role in laundering bitcoins stolen from Mt. Gox. Additionally, Vinnick has been accused by Greek authorities of laundering approximately $4 billion in bitcoin. Vinnick is allegedly linked to BTC-e, a bitcoin exchange that was raided by the FBI as part of an investigation. The BTC-e website has been shut down and the domain has been seized by the FBI, the first time the US government has captured a foreign exchange in foreign soil. Investigations by Wizsec, a group of bitcoin security experts, have identified Vinnik as the owner of the wallets to which the stolen bitcoins were transferred, many of which were sold on BTC-e.

With the trial underway in Japan and the indictment against Vinnik, it appears that the separate chains of the Mt. Gox hack has finally come together. Whether any of these will lead to a recovery of all or any of the stolen bitcoins remains to be seen, but it looks like we’ll have at least some clarity on Mt. Gox hack in the near future.

Can Bitcoin Hacks Happen Again?

The short answer is it can. There are many active bitcoin exchanges today, some of which are more reputable than others. Popular exchanges like Coinbase are relatively transparent about their operations, as well as offering insured deposits and backed by reputable venture capitalists. However, they will also become targets of the best hackers, who will be happy to exploit any security holes.

And if the above is enough to scare you, my final piece of advice is to make sure you don’t store your bitcoins on any exchanges.
