Japanese cryptocurrency exchange loses more than $500 million to hackers

Japanese cryptocurrency exchange Coincheck says Friday that around 523 million of the exchange's NEM coins were sent to another account around 3 a.m. local time.

The stolen coins were worth about 58 billion yen at the time of detection, or roughly $534.8 million, according to the exchange.

Coincheck management says it held the NEM coins in a "hot" wallet, referring to a method of storage that is linked to the internet.

Hackers stole several hundred million dollars' worth of a lesser-known cryptocurrency from a major Japanese exchange Friday.

Coincheck said that around 523 million of the exchange's NEM coins were sent to another account around 3 a.m. local time (1 p.m. ET Thursday), according to a Google translate of a Japanese transcript of the Friday press conference from Logmi. The exchange has about 6 percent of yen-bitcoin trading, ranking fourth by market share on CryptoCompare.

The stolen NEM coins were worth about 58 billion yen at the time of detection, or roughly $534.8 million, according to the exchange. Coincheck subsequently restricted withdrawals of all currencies, including yen, and trading of cryptocurrencies other than bitcoin.

Bloomberg first reported the hack. A CNBC email sent to Coincheck's listed address bounced back.

Cryptocurrency NEM, which intends to help businesses handle data digitally, briefly fell more than 20 percent Friday before recovering to trade about 10 percent lower near 85 cents, according to CoinMarketCap. Most other major digital currencies, including bitcoin, traded little changed on the day.

Coincheck management said in the press conference that it held the NEM coins in a "hot" wallet, referring to a method of storage that is linked to the internet. In contrast, leading U.S. exchange Coinbase says on its website that 98 percent of its digital currency holdings are offline, or in "cold" storage.

The Japanese exchange said it did not appear that hackers had stolen other digital currencies.

The Coincheck hack follows news in December that a South Korean cryptocurrency exchange called Youbit lost 17 percent of its digital assets. Its parent Yapian filed for bankruptcy.

In another high-profile case, Tokyo-based Mt. Gox filed for bankruptcy in 2014 and said it lost 750,000 of its users' bitcoins and 100,000 of the exchange's own. The company was the largest bitcoin exchange at the time.

Morgan Stanley analysts estimated in mid-December that more than $630 million in bitcoin has been lost to hackers.

    This foreign money will not be backed by a tangible commodity (equivalent to gold or silver); bitcoins are traded on-line which makes them a commodity in themselves. If you want to learn more about this topic please visit https://quickex.io

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke...

New ATM's: withdraw money with veins in your finger

New cash machines: withdraw money with veins in your finger Cash machine technology that reads the pattern of finger veins is already available in Japan and Poland   By Telegraph Reporters 6:59PM BST 15 May 2014 Cash machines could soon be installed with devices that identify customers by reading the veins in their fingers. The technology is already being rolled out in Poland, where 1,730 cash machines will this year be installed with readers, negating the need for a debit card and Pin. Developed by Hitachi, the Japanese electronics firm, the machines read the patterns of the veins just below the surface of the skin on your finger using infra-red sensors. The light is partially absorbed by haemoglobin in the veins to capture a unique finger vein pattern profile, which is matched to a profile. The technology is used by Japanese banks and also in Turkey, offering “groundbreaking levels of accuracy and speed of authentication”, Hitachi said, which in t...
