96 Entries to date. Last updated in Jan 2023.

In this post, I collected data from various sources to compile a comprehensive list of all the hacks that we know of, from the early days of crypto, to most recent times.

Crypto exchanges (both centralized and decentralized) get hacked all the time, which is why I always advise my friends and followers to keep their long term holdings in HD wallets (cold storage) instead of risking their hard-earned money being stolen.

Exchanges are not the only victims of such attacks, in fact, according to the latest report by blockchain research company Chainalysis, 69% of all crypto theft taken place in 2022 came from cross-chain bridge hacks. An estimated $2 billion worth of cryptocurrency had been stolen in 13 cross-chain bridge attacks, mostly in 2022.

Last year, more than 40 hacks and breaches were reported and we are witnessing a continuous rise in crypto fraud-related incidents, with the number of offenses growing by 40% every year, according to Markets Insider.

This is why I feel it’s important to highlight the risks we are facing when investing or using cryptocurrencies and I compiled this list for my own reference when I create crypto content and I share this with you here.

This list is updated regularly and new entries are added accordingly.


12 October 2022 – Mango Markets

Solana-based crypto exchange Mango Markets was hit with an exploit of over $100 million. The incident saw the hackers manipulate price oracle data, which enabled them to take out under-collateralized cryptocurrency loans. At the same time, the network has suffered several outages that appear to deter investors. The most recent outage was recorded on October 1, lasting at least six hours. Overall, in 2022 alone, the network suffered at least five significant outages all due to attacks on the network, with some running into days.

While this was not an exchange hack, I include it here as it is of huge magnitude, one of the biggest single hacks to date.

The chain was promptly re-activated, but the incident sparked many complains about centralization of the blockchain network.

Although not a hack of funds, this was a data breach, so I am still adding it to this list.
In an official statement about this hack, the CEO shared the following:

“On the 13th of November 2020, a domain hosting provider “GoDaddy” that manages one of our core domain names incorrectly transferred control of the account and domain to a malicious actor. This gave the actor the ability to change DNS records and in turn, take control of a number of internal email accounts. In due course, the malicious actor was able to partially compromise our infrastructure, and gain access to document storage…
We can confirm client funds are accounted for, and remain safe and secure. MPC-based and cold storage crypto wallets are secured and were not compromised.”

An attacker stole over $500,000 in Ether, Wrapped Bitcoin, Chainlink, and Synthetix tokens.

Balancer CTO Mike McDonald explains that the attacker had borrowed $23 million in WETH tokens in a flash loan from dYdX. They then traded against themselves with Statera (STA), a token that uses a transfer fee model and burns 1% when traded. The attacker repeated this back and forth 24 times, draining the STA liquidity pool. Because Balancer thought it had the amount of STA remained unchanged, it released WETH in the amount of the original balance, giving the attacker a larger margin for every trade.

The attacker repeated this attack with WBTC, LINK and SNX, all against Statera tokens.

May 2020 – Coincheck

In an official statement, the Tokyo-based organization shared that attackers hijacked one of Coincheck’s domains to carry out spear-phishing attacks on customers.

“8:58 SGT on April 18th. An attacker used a vulnerability with Uniswap and ERC777 to perform a reentrancy attack. For technical details please refer to Open Zeppelin’s explanation here. 12:12 on April 18th. The Tokenlon team observed the anomaly, defined the incident as a P0-level security issue and established an emergency response team. 12:49 on April 18th. After evaluating the situation, Tokenlon suspended the transfer of imBTC and notified imBTC partners including Lendf.Me to evaluate potential security risks. 17:00 on April 18th. imBTC transfer was resumed after receiving the confirmation from Lendf.Me and other partners that it is OK to do so. 09:28 on April 19th. Tokenlon received a message from Lendf.me about a reentrancy attack, similar to the one happened to Uniswap, resulting in a large number of abnormal borrowing on the platform. 10:12 on April 19th. In order to cooperate with the investigation of the reentrancy attack, Tokenlon suspended the transfer of imBTC.”

The company has since reimbursed its customers.

Investigations revealed that the hack may have begun as early as September 2011. Prior to September 2011, Mt. Gox’s unencrypted private key appears to have been copied. The hacker(s) used the file to access and gradually steal funds associated with Mt. Gox’s private keys without detection. The shared keypool led to address re-use, with the Mt. Gox systems misinterpreting the transfers as deposits being moved. Whenever the wallets emptied, Mt Gox credited an additional 40,000 bitcoins to multiple user accounts.

January 2013 – Vicurex

Vicurex has not confirmed the amount lost in two hacks but reported that it was near insolvency in 2014. As a result of the hacks and subsequent fund withdrawals by spooked users, Vicurex froze withdrawals and declared mitigation plans. Several customers filed a lawsuit against the company for withholding their funds.

December 2012 – Bitmarket

BitMarket.eu was hacked several times with the most infamous incident taking place in 2012.

Three months following the announcement, Trębacz notified users that Yevgeniy Nikulin, a Russian national who was arrested for hacking Dropbox, Formspring, and LinkedIn, had stolen 620 BTC from the exchange by using an SQL injection to gain access to BitMarket’s servers.

September 2012 – BitFloor

Following an attack that lost the exchange over $250,000 in cryptofunds, BitFloor Founder Roman Shtylman shared that hackers targeted the exchange’s servers. Although BitFloor encrypted the wallet keys needed to conduct transactions, it also kept an unencrypted backup. The attacker(s) likely gained access to this backup.

March 2012 – Bitcoinica

Three separate incidents led to Bitcoinica’s downfall. On March 1, Linode, a web hosting provider whose clients included Bitcoinica, was hacked. The unknown intruder successfully stole 43,000 BTC from Bitcoinica.

On May 11, attackers used a compromised email account to lift 18,500 BTC from Bitcoinica’s hot wallet.

On July 13, another attacker gained access to a LastPass account containing passwords needed to access the MtGox account. The LastPass account used the same password as the MtGox API key used by the Bitcoinica server when Bitcoinica was still live. The attacker withdrew 40,000 BTC and 40,000 USD.


October 2011 – Bitcoin7

The company reported a theft of 5,000 BTC and shared that attacks originating from Russia and Eastern Europe targeted Bitcoin7’s server, compromising wallets and user data.

June 2011 – Mt.Gox

A hacker accessed credentials from a Mr. Gox auditor’s breached computer to send a large number of bitcoins to himself, causing the price of Bitcoin to fall below one cent. The hacker then created a massive ask order for any price and made a small fortune as the prices corrected in minutes.
