More than $70 million stolen in bitcoin hack.
On Friday afternoon in Asia about 4,700 bitcoins have been
stolen from the site, the CEO said. NiceHash CEO Marko Kobal said that
yesterday morning at 1:00 am a hacker or hacker group broke into our system
through a compromised computer.
The value of the 4,700 bitcoins stolen is estimated at $ 75
million, while in recent weeks Bitcoin's value has risen sharply and it
surpassed $ 17,000 for the first time on Thursday. According to many people, a
hack was launched on a leading digital currency platform. NiceHash provides a
platform for users to exploit for other cryptocurrencies and get paid in
bitcoin.
The incident is quite serious because there are signs that
the attack is done quite sophisticated and in close coordination. The system
has been compromised through the use of certificates by one of the company's
engineers.
Immediately to cope and overcome the consequences, NiceHash
has announced all major bitcoin exchanges and mining sites about violations to
track and possibly recover stolen coins. This incident again warns of the vulnerability
of some digital currency platforms. Hackers around the world, for their own
purposes, may endeavor to steal bitcoin in increasingly sophisticated ways.
More information about bitcoin and cryptokurrencies:
A cryptocurrency (or crypto currency) is a digital asset
designed to work as a medium of exchange that uses cryptography to secure its
transactions, to control the creation of additional units, and to verify the
transfer of assets. Cryptocurrencies are classified as a subset of digital
currencies and are also classified as a subset of alternative currencies and
virtual currencies.
Bitcoin, created in 2009, was the first decentralized
cryptocurrency. Since then, numerous cryptocurrencies have been created. These
are frequently called altcoins, as a blend of bitcoin alternative. Bitcoin and
its derivatives use decentralized control as opposed to centralized electronic
money/central banking systems. The decentralized control is related to the use
of bitcoin's blockchain transaction database in the role of a distributed
ledger.
An Initial Coin Offering (ICO) is an unregulated means by
which funds are raised for a new cryptocurrency venture. In an ICO campaign, a
percentage of the cryptocurrency is sold to early backers of the project in
exchange for legal tender or other cryptocurrencies, often Bitcoin or Ethereum.
As of September 2017, there were over 1100 digital currencies in existence.
Bitfinex, a Hong Kong-based bitcoin exchange, was shut down
last year after hackers steal nearly 120,000 bitcoins worth more than $ 65
million at the time.
Last year, cyber thieves made about 19,000 bitcoins after
hacking into the Bitstamp European exchange. FireEye's cybersecurity warned
that this type of attack would take place more and more, and that it would be
capable of causing greater damage.
On November 21, 2017, an online company (Tether) which backs
bitcoin cryptocurrency with fiat currency claims they were hacked, losing $31
million in USTD from their primary wallet. The company has 'tagged' the stolen
currency, hoping to 'lock' them in the hacker's wallet. Tether indicates that
it is building a new core for its primary wallet in response to the attack in
order to prevent the stolen coins from being used.
