The hacker breached the system of the largest travel agency of South Korea Hanatour and kidnapped personal information of more than a million customers. This is reported by the KBench.

For the return of data, the hacker demanded a one-time ransom in bitcoins. The amount of the ransom was not disclosed.

According to information from the travel agency, the hacker was able to crack the security system through complex phishing attacks and the spread of malicious software. So the attackers got access to the servers of the company, which kept the names, mobile phone numbers, social insurance, home addresses and other information of the travel company's clients.

As reported by CoinJournal, in the upcoming weeks, Hanatour will join forces with government agencies and cybersecurity companies to investigate the attack. Considering the involvement of the South Korean law enforcement, it is highly unlikely that Hanatour will pay the Bitcoin ransom.

Hanatour is considered South Korea’s largest and most reputable travel agency when measured on revenue, client base and reviews. Since 2007, the company has aggressively moved into new international markets, establishing offices in popular tourist destinations including Japan and China.

HashFlare Users to Face Withdrawal Issues

Looks like Bitcoin cloud mining is not super profitable
18 July 2018   97

Users of HashFlare mining pool can't withdraw their funds, while their contracts are threatened with a temporary ban. Even lower restrictions on withdrawal of funds in the amount of 0.03 BTC caused problems for users, but the service raised the threshold to 0.05 BTC and 0.1 ETH . This is reported by Cryptovest.

In addition, financial pyramids are often promoted under the guise of mining contracts for cloud mining. For last few months, there was a big jump in mining difficulty of many cryptocurrencies, so, old contacts had become unprofitable.

As reported, the reason for the locked funds dates back further - at the beginning of June, so much hashing power was flowing into the Bitcoin network that contracts saw all the mined coins go toward their maintenance fee.

Currently, more and more users who have purchased contracts at earlier stages are facing the fact that they can not withdraw their funds. One of them managed to return the money spent through the bank card operator after filing a corresponding complaint.

To anybody that purchased a Hashflare cloud mining contract with a credit card, it might be possible to get a refund with that credit card as one of my followers tipped me. He bought his contracts at the end of 2017.

The hash rate of bitcoin increased from 13 EHash / s at the beginning of the year to more than 40 EHash / s in recent months. The difficulty of mining in the present conditions depends on the circumstances of the specific miner. The cost of bitcoin mining for some of them is $ 4,400, while others spend about $ 5,800. However, in 2018, cloudy mining is called an even more dubious occupation than before, especially when it comes to mining bitcoin.
