Over $11 billion worth of cryptocurrencies has been stolen in different cryptocurrency hacking incidents since 2011. The figures calculated by InsideBitcoins.com show that a significant amount was lost in cryptocurrency exchange hackings. Other affected platforms include cryptocurrency wallets and mining platforms.

The first blockchain hacking was in 2011 when Tokyo based Mt.Gox lost approximately 2000 BTC ($17.2 million). This was the only hack to be recorded that year. The hack was allegedly orchestrated due to a compromised computer belonging to an auditor within the firm. By Jan 2014, Mt.Gox was the leading Bitcoin exchange in the world based on the fact that it controlled at least 70% of all global Bitcoin transactions.

However, the exchange suffered one of the biggest hacks in the world that rendered it bankrupt three years later. In February 2014, the exchange lost approximately $6.5 billion worth of Bitcoin (740,000BTC). Interestingly, this amount represented about 6% of all bitcoin in existence at the time. Although efforts by exchange led to the recovery of almost 200,000 BTC, the rest were never traced.

In 2012, at least $1.2 billion was lost in two main hackings. Bitcoinica, a platform that enabled leveraged speculation in its contract-for-difference (CFD) market against the Bitcoin to USD exchange rate was the worst hit, losing $1.05 billion (740,000 BTC). Bitcoinica suffered three hacks in the same year on diverse dates between March, May, and July.

The May hack was a result of decrypting the Bitcoinica hot wallets which led to a loss of 43,554 BTC. In another attack, illegal access to the Bitcoinica database led to a loss of 38,000 BTC. In July, an attacker made away with the 40,000 BTC but later recovered.

On the other hand, BitFloor lost $208 million worth of crypto (24,000 BTC). The hack was successful after an attacker gained access to an unencrypted backup of the wallet keys.

At least $109.6 million was stolen in major cryptocurrency exchanges hacking across 2013. Unregulated stock market denominated in the Bitcoins platform PicoStocks lost about $62 million (7,196 BTC). The hacking was mainly linked to an inside job because the Bitcoins were lost in both hot and cold wallets. Normally, cold wallets can’t be accessed in online attacks.

Another notable hack was at Inputs.io, a P2P digital currencies exchange. In the hack, attackers managed to bypass 2FA due to a flaw on the server host side. In May 2013, Vicurex suffered a hack that resulted in the loss of different cryptocurrencies including 1,454 BTC($12.6 million), 225,263 TRC ($8K ), and 23,400 LTC ($1.36 million) totaling to $12.6 million.
