One researcher estimates that more than 14 percent of Bitcoin and rival currency Ether has been stolen. North Korean leader Kim Jong Un has allegedly sent his hackers out to swipe digital coins as his country faces tightening trade sanctions. As prices of digital assets have soared, the platforms have become increasingly juicy targets for hackers. Yes, there’s a long history of thefts at cryptocurrency exchanges and wallets, dating back to the infamous robbery of Tokyo-based Mt. Aren’t these exchanges being hacked a lot? While this approach worked for Ethereum in 2015, NEM Foundation Vice President Jeff McDonald said a fork is not an option. The so-called hard fork would create two versions of NEM, one that has never been hacked and another containing the stolen funds. They could change the NEM blockchain by rolling back the record to a point before the attack. What else can NEM developers do to fix this? There are also “tumbler” services, designed to obscure both identities and transactions, but the huge total amount of money stolen presents a challenge. ShapeShift, which publishes all trades on its platform, said they have already blocked addresses associated with the hack. Converting NEM coins into a more anonymized currency, like Monero, could conceivably launder them. The thief could attempt to shake off surveillance by going through a service like ShapeShift, which offers cryptocurrency trading without collecting personal data. Does that mean the hackers won’t be able to cash in? Each one has been labeled with a tag that reads “coincheck_stolen_funds_do_not_accept_trades : owner_of_this_account_is_hacker.” NEM developers created a tracking tool that would allow exchanges to automatically reject stolen funds.
Trouble is, no one knows who owns the accounts. Coincheck has identified and published 11 addresses where all 523 million of the stolen coins ended up. Because transactions for Bitcoin and the like are all public, it’s easy to see where the NEM coins are - even though they’re stolen. That’s one of the stranger aspects of these heists. Coincheck also lacked multi-signature security, a measure requiring multiple sign-offs before funds can be moved. Exchanges generally try to keep a majority of customer deposits in cold wallets, which aren’t connected to the outside world and thus are less vulnerable to hacks. The company did own up to a security lapse that allowed the thief to seize such a large sum: It kept customer assets in what’s known as a hot wallet, which is connected to external networks. More recently, South Korean cryptocurrency exchange Youbit last month shut down and filed for bankruptcy after being hacked twice last year.Coincheck hasn’t disclosed how their system was breached beyond saying that it wasn’t an inside job. Gox, which once handled 80% of the world’s bitcoin trades, filed for bankruptcy after losing around half a billion dollars worth of bitcoins. It added that the hacker had not moved any of the funds to any exchange or personal accounts but that it had no way to return the stolen funds to its owners.

Singapore-based NEM Foundation said it had a tracing system on the NEM blockchain and that it had “a full account” of all of Coincheck’s lost NEM coins. Crypto-currency related shares mostly rose in Tokyo, with GMO Internet, which offers cryptocurrency exchange service, gaining 5.7 pct.
NEM fell to $0.78 from $1.01 on Friday but recovered to $0.97 on Monday, according to CoinMarketCap. If Coincheck screws up its crisis management, that could deal a blow to the current cryptocurrency fever.” “This incident showed that the problem has not been solved at all. “It’s been long said that cryptocurrencies are a solid system but cryptocurrency exchanges are not,” said Makoto Sakuma, research fellow at NLI Research Institute. If necessary, it will conduct on-site inspections of other exchanges, an official told a briefing. The FSA said it ordered Coincheck to submit an incident report and measures for preventing a recurrence by Feb. It also does not use an extra layer of security known as a multi-signature system. The NEM coins were stored in a “hot wallet” instead of the more secure “cold wallet,” outside the internet, Coincheck said. The Financial Services Agency (FSA) on Monday ordered improvements to operations at Tokyo-based Coincheck, which on Friday suspended trading in all cryptocurrencies except bitcoin after hackers stole 58 billion yen ($534 million) of NEM coins, among the most popular digital currencies in the world.Ĭoincheck said on Sunday it would return about 90% with internal funds, though it has yet to figure out how or when. The theft highlights the vulnerabilities in trading an asset that global policymakers are struggling to regulate and the broader risks for Japan as it aims to leverage the fintech industry to stimulate economic growth.
