Bitcoin exchange shuts down after being hacked twice in one year
19 December, 2017
This post was originally published on this site

A South Korean Bitcoin exchange has collapsed after suffering its second hack in less than a year.

As The Telegraph reports, YouBit has announced that it suffered a hack at 04:35am local time today, which saw criminals steal 17% of its total assets.

As a consequence, YouBit has declared itself bankrupt and – by the time you read this article – will have shut down forever.

In an announcement to customers, YouBit said it would allow users to withdraw up to 75% of their funds. But customers will have to wait until after the bankruptcy process to see what (if any) of the remainder of their Bitcoin investments will be made available.

No doubt some observers will fail to feel much sympathy with investors who are stung by YouBit’s sudden and unexpected shutdown. After all, the same site suffered a separate hack in April which saw 4,000 Bitcoins stolen (worth about US $5.5 million then, but an eye-watering US $74 million at today’s prices).

To misquote Oscar Wilde, to have your Bitcoin exchange hacked once may be regarded as misfortune; to have it happen twice looks like carelessness.

In its message to customers, YouBit said that it had made efforts to improve security after the earlier attack, but it simply wasn’t enough.

[Emergency – Important]

I am very sorry to inform you again with the sad news.

After the accident in April, we have done our best to improve the security, recruitment and system maintenance, and have managed to lower the hot wallet rate.

Then, at 4:35 am, we lost our coin purse due to our hacking .

The coin loss at 4:35 am is about 17% of total assets. The other coins were kept in the cold wallet and there were no additional losses.
