Investors aren't the only ones interested in cryptocurrencies. Hackers like them, likewise. South Korean Bitcoin exchange Bithumb is the latest victim; this week, it reported a breach that may have stolen $31 million from its digital coffers.
But it's not the first. Over the years, cybercriminals have looted billions in virtual currencies, sending shockwaves through the marketplace. Exchanges have been shut downwardly, prices take sunk, and investors have lost fortunes. Below, we take a look at the biggest heists to hit cryptocurrency institutions, how they occurred, and if any lessons tin be learned.

Details about the hack remain thin, but the incident occurred as North Korean hackers have been preying on cryptocurrency providers beyond the globe, typically via phishing emails sent to those in charge of these exchanges.
As of today, Coinrail remains down and investors are growing impatient. The good news is that 70 percent of the exchange's holdings were held in a "common cold wallet," a digital coffer kept offline, and information technology plans to compensate investors.
Bitgrail – February 2022
Amount stolen: At to the lowest degree $150 million in Nano tokens
This heist at an Italian cryptocurrency exchange has brought out the conspiracy theorists. In February, Bitgrail reported a alienation involving a digital currency called Nano. It blamed the heist on bad software provided past Nano's programmer, but the squad backside Nano claims Bitgrail was actually insolvent and trying to scam users.
The bickering has left investors with nothing and compelled some to take Bitgrail and Nano'south developers to court. The whole controversy underscores the risks when investing in cryptocurrencies: the engineering tin exist immature, parties involved can be shady, and much of the market place remains unregulated. Continue with caution.
Coincheck – January 2022
Amount stolen: $500 million in the NEM currency
Information technology's never a expert idea to go on all your eggs in one basket. That'southward what appears to have happened at Japanese cryptocurrency exchange Coincheck; information technology stashed over 523 one thousand thousand NEM coins in what's known as a "hot wallet," a digital coffer connected to the greater internet.
As a result, a bad actor in January somehow gained access to the wallet, and stole all the funds inside. Co-ordinate to Coincheck, 260,000 investors were affected.
Fortunately, the exchange has been providing refunds, but the hack may take helped sink NEM's toll; since the breach, its value has dropped most 80 percent.
NiceHash – December 2022
Amount stolen: $lxx million in Bitcoin
NiceHash isn't a traditional substitution, but a digital market for cryptocurrency enthusiasts to purchase and sell calculating ability to mine the digital golden. But in December it went offline afterwards a hacker stole 4,700 bitcoins from the Slovenian company in a mere two hours.
According to NiceHash, a hacker using an IP address exterior the European union compromised a company calculator, stole an engineer's credentials, and infiltrated NiceHash'due south internal network to loot funds from user accounts.
At the time, NiceHash'due south CEO chosen the attack "incredibly coordinated," but conspicuously the company had a major hole in its security. Since then, NiceHash has redesigned the market'due south payment system to include the manual confirmation of every cryptocurrency transaction that leaves its systems.
Bitfinex – August 2022
Corporeality stolen: $70 1000000 in Bitcoin ($800 million in today'south value.)
Though Bitfinex upgraded to a new wallet system several years ago with the help of Bitgo, which specializes in securing digital currencies, the overhaul failed to terminate a hacker from stealing 120,000 bitcoins from the substitution.
Critics claim Bitfinex's system was essentially storing its Bitcoin into hot wallets. Supposedly, the wallets were secured with multiple cryptographic keys, only still the hacker managed to break in. Bitfinex now says it stores 99.5 percent of user funds in cold wallets.
Bitstamp – Jan 2022
Amount stolen: $5 million in Bitcoin (or $120 one thousand thousand in today's value)
The details of this hack emerged when a Reddit user posted what appears to be Bitstamp's internal incident report nearly the breach. It details how a hacker launched a phishing campaign on company employees and stole over 18,866 bitcoins from the exchange.
For several weeks, the hacker targeted six employees, including Bitstamp's CTO, over Skype and email with promises of free concert tickets, a chore, or membership in a computing society. Eventually, the hacker tricked a visitor organisation ambassador into opening a certificate loaded with malware, opening access to the company'southward hot wallet.
Fortunately, the stolen funds were merely a small portion of Bitstamp's total Bitcoin reserves, according to the incident report, since the substitution used a hot and cold wallet organisation to store its cryptocurrency.
Mt. Gox – January 2022
Amount lost: $470 meg ($5.seven billion in today's value.)
Perhaps the most notorious cryptocurrency hack, the Mt. Gox exchange lost 850,000 bitcoin in a heist that secretly occurred over the bridge of 2 years. Cryptocurrency experts have traced the breach back to September 2022 when the private keys for Mt. Gox's hot wallet were stolen, perhaps past a Russian hacker named Alexander Vinnik, who was arrested in Greece last twelvemonth for Bitcoin laundering.
By mid-2013, Vinnik may have stolen about 630,000 bitcoin from the Mt. Gox exchange by secretly emptying its wallet. Unfortunately, Mt. Gox's internal systems were shoddy enough that they failed to observe the theft, leading it to close downwards and declare bankruptcy.
