Bitcoin (BTC) came into the picture during the worldwide monetary Crisis of 2008-09 to forestall the planet from financial crises within the future. However, as proven by numerous cryptocurrency scams since their introduction to the world, cryptocurrencies conjointly don’t offer enough security to the users’ funds. Because of the funds being placed digitally (most of the time), hackers notice it easier to steal virtual currencies than physical cash. Also, cryptocurrencies hold on in immense sums are often transferred anonymously, resulting in major heists in the crypto industry.
Let’s take a glance at the biggest crypto thefts of all time in this article. Also, the article will define why crypto exchanges keep getting hacked; why are crypto heists getting larger and what we are able to do to guard ourselves from crypto heists. The biggest crypto heists until now are MT Gox, Linode, BitFloor, Bitfinex, Bitgrail, Coincheck, KuCoin, PancakeBunny, Poly Network, Cream Finance, BadgerDAO, and Bitmart.
Mt.Gox remains the largest cryptocurrency heist in history, with over 850,000 Bitcoins stolen between 2011 and 2014. Mt.Gox claimed that an error causing the loss was due to a bug underlying in Bitcoin, known as transaction malleability. It is the process of changing the unique identifier of a transaction by changing the digital signature used to produce it. In September 2011, it was discovered that MtGox’s private keys had been compromised and the company did not use any auditing techniques to discover the breach. Additionally, because MtGox routinely reused Bitcoin addresses, the stolen key set was used to constantly steal new deposits, and by mid-2013, over 630,000 BTC had been withdrawn from the exchange. of ongoing flights can be gleaned from blockchain transactions to support this claim. Many companies use cold and hot wallets to minimise large losses, as shown by Mt.Gox. All coins are transmitted to the cold wallet of the exchange, which is manually transferred to the hot wallet if necessary. If an exchange’s server is hacked, the thief can only steal money from the hot wallet, allowing the exchange to decide how many coins they are willing to risk.
Using multisig (the requirement for multiple keys to authorise a BTC transaction) is not a silver bullet in itself, as evidenced by another massive heist at Bitfinex, which led to the theft of 119,756 BTC. Exchange Bitfinex has partnered with BitGo to act as a third-party escrow for customer withdrawals. It also appears that Bitfinex chose not to use cold wallets to gain legal exemption from the Commodities and Exchange Act. allow transactions to be generalised.
Bitgrail was a small Italian exchange that traded obscure cryptocurrencies such as Nano (XNO), formerly known as RaiBlocks. Nano was worth just 20 cents in November 2017; however, when prices were hovering around $10, the exchange was hacked in February 2018, bringing Bit Grails losses to $146 million. Cryptocurrency cyber theft fooled more than 230,000 people Unfortunately, small exchanges don’t implement basic protections, like a cold storage wallet, putting a lot of money at risk, according to the director of the National Cybercrime Centre, Ivano Gabrielli, it became clear that the CEO of BitGrail was involved in the BitGrail scandal.
Japan-based Coincheck suffered the theft of NEM (XEM) tokens worth $530 million in January 2018. The identity of the Japanese hackers who broke into the security system remains a mystery. Following the investigation, Coincheck revealed that the hackers were unable to access their system due to a lack of personnel at the time. The hackers managed to figure out the system due to the funds held in the hot wallet and insufficient security measures in place.
KuCoin informed in September 2020 that hackers got access to the private keys for their hot wallets before withdrawing large amounts of Ethereum (ETH), BTC, Litecoin (LTC), Ripple (XRP), Stellar Lumens (XLM), Tron (TRX)) and Tether (USDT). Lazarus Group, a North Korean hacker group, has been accused of stealing cryptocurrency exchange KuCoin, resulting in a loss of funds of $275 million. However, the exchange was able to recoup around $240 million in payouts afterwards.
The PancakeBunny flash loan attack, in which hackers were able to take out $200 million from the platform, occurred in May 2021 and is one of the most popular cases of cryptocurrency theft. The attacker lent a large sum of Binance Coin (BNB) before manipulating its price and selling it on PancakeBunny’s BUNNY/BNB market to carry out the attack. One needs to borrow a flash loan before repaying the amount in one go. The hacker obtained a large number of BUNNY via a flash loan, then threw all the BUNNY in the market to lower the price, then redeemed the BNB using Pancake Swap.
In August 2021, a hacker stole digital tokens worth around $600 million in one of the biggest cryptocurrency thefts ever. A hacker known as “Mr. White Hat” exploited a weakness in the Poly Network, a DeFi platform. The story has gotten stranger every day since the first flight. Mr. White Hat not only maintained a consistent and public dialogue with Poly Network, but he also returned everything stolen a week later, with the exception of $33 million in Tether (USDT) which was frozen by diffusers. White Hat has already received a $500,000 reward for returning all the stolen money, as well as a job offer to become Poly Network’s senior security officer.
Hackers stole $130 million in the Cream Finance incident in October 2021. This was Cream Finance’s third cryptocurrency heist of the year in which hackers took $37 million in February 2021 and $19 million in August 2021. The money appears to have been borrowed in a flash in a very complicated transaction costing over 9 ETH in gas and involving 68 different assets. The attacker used MakerDAO’s DAI to produce a large number of yUSD tokens while taking advantage of the yUSD price calculation by the oracle. As a result, on the Ethereum network, they were able to take all of Cream Finance’s tokens and assets, totaling $130 million.
A hacker managed to rob assets from several cryptocurrency wallets on the DeFi network, BadgerDAO, in December 2021. The incident is connected to phishing once a malicious script was injected into the program of the web site through Cloudflare. The hacker used an API key to take out $130 million in funds. The API key was created without the data or permission of Badger engineers to often inject malicious code into a fraction of its customers. recovered because the pirates were still required to withdraw funds from Badger’ vaults.
In December 2021, a Bitmart hot wallet hack led to the theft of approximately $200 million. It was originally thought that $100 million was stolen via the Ethereum blockchain, but further research revealed that an additional $96 million was stolen via the Binance Smart Chain blockchain. Over 20 tokens were taken, including altcoins such as BSCUSD, Binance Coin (BNB), BNBPay (BPay) and Safemoon, along with significant amounts of Moonshot , Floki Inu and BabyDoge tokens.
All bitcoin exchange security measures are proactive, with the aim of putting an end to these heist. in line with the discussion above, proactive security measures have reduced the impact of thefts, but sadly will not prevent a theft. Basically, thanks to the irreversible nature of the blockchain, there’s very little AN exchange can do to prevent a theft once the suitable non-public keys have been stolen. One must always review all claims concerning finance in cryptocurrencies, particularly if they sound too smart to be true.

Additionally, any supply that needs a direct value ought to be rejected, no matter the amount, particularly if the value is to be paid in cryptocurrencies.
