Following an earlier breach, MintPal was purchased by Moolah. After a failed relaunch of MintPal, Moolah announced it was shutting down but MintPal would remain in operation following an offline period to address infrastructure security.

July 13, — MintPal. July — Cryptsy. March 4. This will result in a negative balance, but valid insertions into the database, which then get picked up by the withdrawal daemon. March — CryptoRush. February 7, — Mt. The victim of a massive and prolonged hack, Mt.

November 17, - BIPS. November 11, — BitCash. According to BitCash, their server was hacked and disabled. The hackers then used bitcash. October 23, - Inputs.

December 21, - Bitmarket. September 5, — BitFloor. 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 1, — Bitcoinica. On March 1, Linode, a web hosting provider whose clients included Bitcoinica, was hacked. Today Bitfinex remains one of the largest Bitcoin exchanges. Although many of you might not remember Bitcoinica, they weigh in at the number three spot in this list, having lost roughly , BTC in three separate heists in Indeed, each of those three heists would have put Bitcoinica in the third spot all by themselves.

Bitcoinica had their infrastructure hosted with Linode, and hackers were able to get away with 43, BTC. Some suspect the hacker was actually a Linode employee, but the identity of the thief has never been discovered. The company went into conservatorship and then the final insult happened in July, with 40, BTC in funds held at Mt. Gox disappearing. Liquidation of the company funds and distribution to former clients was to happen over several months following an August receivership, however it appears no such distribution has occurred yet.

Allinvain is the pseudonym of a Bitcointalk forum user who posted in June of a hack that saw roughly 25, Bitcoin stolen from his computer. Allinvain had been an early Bitcoin miner, and had accumulated the 25, BTC through and early While he was able to identify the address where the BTC was transferred, he was never able to recover a single coin.

The hack was able to occur because allinvain kept his wallet recovery seed in an unencrypted file on a computer that was infected with malware. Indeed, Bitcoin was only a few cents at the time and Allinvain could have been less concerned. This is not a well-known story, but this was the first large hack, and should be taught to every cryptocurrency user as a lesson in operational security.

Just behind the allinvain hack is a 24, BTC loss suffered by the exchange Bitfloor in September At the time Bitfloor was the fourth largest U. A hacker was able to access client accounts with backup keys due to the funds being held in a hot wallet. After shutting down for several days following the incident the company said they would reimburse all lost funds, however that never happened.

In April , less than 1 year after the hack, the exchange closed down, citing the closure of its accounts by its bank as the reason. Due to lessons learned from this hack and numerous others, exchanges make use of significant cold storage. This could have prevented the Bitfloor hack. This hack occurred due to social engineering, in which the hacker made repeated attempts to contact customer service representatives and other Bitstamp employees via Skype and email, attempting to entice them into opening a malware infected file by posing as reporters and other industry members.

Eventually the hacker was able to get an employee to open the infected file, thus infecting their machine and giving the attacker access to the Bitstamp network. From there they were able to access a hot wallet on a server and siphon off 19, BTC. While U. Customers accounts were not affected by the hack, and Bitstamp continues to operate with a solid reputation as the oldest active Bitcoin exchange.

Cryptsy was another US based exchange that was one of the most voluminous exchanges back in That was until the exchange collapsed in December of the same year as a result of being insolvent. The founder claimed that the hack took place in early and resulted in the exchange losing 13, BTC and a further , LTC.

It was suspected that a developer who worked on the exchange had inserted a trojan into the code which would allow him remote access to the servers. There were, however, many users who suspected foul play by the founder himself and they initiated a class action lawsuit against him. Big Vern had vanished prior to the ruling and many suspect that he may be hiding in Asia somewhere.

Whether it was an inside job no one can ever know but we can all agree that using an anonymous developer to develop critical code for your cryptocurrency exchange is a bad idea. This was a relatively recent Bitcoin hack that took place on the 7th of May Up until that incident, the exchange had managed to avoid any sort of security breaches. Rather, the hackers spent were slowly accumulating a large array of user API keys, 2FA codes and other information.

They managed to do this through a number of other well-known attack vectors and social engineering tactics. These include the likes of Phishing and computer viruses. With access to this information, a hacker can initiate a withdrawal request on a client account. They were extremely patient with their actions and on the 7th of May initiated the mass withdrawals from these user wallets. They structured the transactions in such as way that they were able to circumvent the internal Binance risk limits.

The 7, BTC was sent in one transaction to the following address. Binance immediately halted all deposits and withdrawals once they noticed the transaction. Binance covered the entire cost of the hack and no users were affected. While these Bitcoin hacks may be painful to read about, it is incredibly helpful to study them and learn about the causes behind the breaches.

Many of the enhancements in crypto security have come about as a result of findings of previous incidents like those above. Of course, hacks do still occur but they are not at the same scale as in the past. Even if a hacker was able to exfiltrate such a large number of coins today, it would be nearly impossible for to launder the coins.

Law enforcement and cyber security analysts have developed some of the most advanced blockchain auditing tools that are able to track stolen coins.
