Digital currency that runs without a central bank is known as cryptocurrency. Due to its decentralized structure, which increases security and protects it from intervention from the government, it has grown in popularity.
This does not, however, imply that cryptocurrencies are impervious to hacking. In reality, as the value of cryptocurrencies has soared in recent years, crypto hacks have increased in frequency.
The seven largest cryptocurrency hacks in history will be examined in this article along with the lessons that can be drawn from them.
An Overview of the Seven Largest Cryptocurrency Hacks Ever
Mt. Gox, Bitfinex, Coincheck, DAO, Parity Wallet, Bithumb, and Cryptopia are among the seven largest cryptocurrency hacks in history. Each of these attacks had a substantial effect on the cryptocurrency market, and they should all serve as a reminder to all cryptocurrency fans to be watchful and adopt the appropriate security measures to safeguard their money.
Mt. Gox
The biggest Bitcoin exchange in the world at one point was Mt. Gox. It was compromised in 2014, when 850,000 Bitcoins worth $450 million at the time were stolen. The theft of the Bitcoins occurred as a result of the hack, which was caused by a technical flaw in the exchange.
Impact: Because it caused people to lose faith in the security of Bitcoin exchanges, the Mt. Gox hack had a significant effect on the cryptocurrency market.
Lesson Learned: The Mt. Gox attack serves as a timely reminder that even the safest exchanges are susceptible to hacking. Additionally, it emphasizes the significance of maintaining software updates and speedy vulnerability fixes.
Bitfinex Exploit
120,000 Bitcoins, worth around $72 million at the time, were stolen in 2016 from the Bitfinex exchange. A weakness in the exchange’s security mechanism led to the breach.
Bitcoin’s value significantly declined as a result of the Bitfinex hack, and people lost faith in the security of exchanges.
Lessons Learned: The Bitfinex attack serves as a reminder of the value of putting in place strong security measures and continuously checking them to make sure they are working as intended. It also emphasizes the necessity of exchanges having enough insurance and backup procedures in place to lessen the effects of a hack on the bitcoin market.
CoincheckÂ
523 million NEM tokens, which were taken from the Coincheck exchange in Japan in 2018 and were worth about $534 million at the time, were stolen. A weakness in the exchange’s security mechanism led to the breach.

Lessons Learned: The Coincheck breach serves as a reminder of the significance of appropriate security measures and routine audits to find and patch flaws. It also emphasizes how crucial it is for exchanges to have the right insurance and backup procedures in place in order to lessen the effects of a hack.
DAO
A hack of the Decentralized Autonomous Organization (DAO) in 2016 resulted in the theft of 3.6 million ETH, which was then valued about $50 million. The organization’s code had a vulnerability that led to the breach.
Impact: To recover the assets that were taken, the DAO attack forced a hard fork in the Ethereum blockchain, which had a profound impact on the Ethereum community.
The DAO breach serves as a reminder of the value of thoroughly testing code before deployment and routinely auditing it to make sure that it is operating as intended. It also emphasizes the importance of having suitable security mechanisms in place for decentralized groups to safeguard their funds.
Parity Wallet
In 2017, 153,000 ETH, which was then valued at $30 million, were stolen from the Parity Wallet. The wallet’s source code included a hole that led to the breach.
Impact: The Parity Wallet attack significantly damaged Ethereum’s reputation and caused people to doubt the security of smart contract wallets.
Lessons Discovered: The Parity Wallet hack serves as a reminder of the need of thoroughly testing code prior to deployment and routinely auditing it to make sure that it is operating as intended. It also emphasizes how important it is for customers to select trustworthy wallet providers and adhere to best practices for money security.
Bithumb
A hacker stole cryptocurrency valued at $31 million from the South Korean Bithumb exchange in 2018. A weakness in the exchange’s security mechanism led to the breach.
Impact: As a result of the Bithumb hack, exchange regulations in South Korea and other nations have become more stringent, which has had a substantial effect on the cryptocurrency market.
Lessons Discovered: The Bithumb attack serves as a reminder of the value of appropriate security measures and routine audits to find and patch flaws. It also emphasizes how crucial it is for exchanges to have the right insurance and backup procedures in place in order to lessen the effects of a hack.
