The Hacker Attack

In January 2018, the Coincheck cryptocurrency exchange was hacked, which resulted in stealing about 500 million NEM tokens in the amount of $ 534 million. The cryptocurrency was transferred to 19 accounts, one of which was found to bear no relation to the hacker.

Hacking dealt only with NEF cryptocurrency. As the reason was the lack of sufficient security measures of Coincheck, the team of NEM developers refused to conduct a hard fork. Instead, NEM creates an automated tag system that will automatically tag any account that receives marked money.

After the incident, the Financial Services Agency initiated the verification of 15 Japanese cryptocurrency exchanges, in seven of which including Coincheck there found security breaches. The Agency brought the perpetrators to administrative responsibility, having ordered to improve the security system within a month.

As a result of the hacking, ten crypto traders filed a claim in mid-February against Coincheck for freezing crypto accounts. Another 132 cryptocurrecny investors filed the second claim in early March, demanding about $ 2 million compensation for damages.

The Coincheck Cryptocurrency exchange initially announced that it could not compensate for the losses of all affected users, but then promised to pay compensation to all 260,000 users in yen at its own expense at a rate of about 88.5 yen (about $ 0.83) per NEM coin.

According to the Tokyo consulting firm L Plus, by March 13, 2018, hackers managed to launder 200 million NEM coins to the amount of $ 90 million, but most of them were most likely sold in the darknet.
