The new blackmail virus is called Petya blackmail virus. According to foreign media reports, a variant of Petya extortion virus, which is homologous to wannacry extortion virus technology, broke out in the world on Tuesday. A number of large enterprises including the UK, Ukraine, Poland, Italy, Denmark, Russia and the United States reported that they were attacked by the virus. Among them, the government, state-owned banks, transportation, energy and other key infrastructure and departments in the hardest hit Ukraine were attacked, Even the prime minister's computer was attacked
similar to wannacry, unlocking Petya virus also requires payment of encrypted digital currency.

According to the public data of the bitcoin trading market, there were 10 ransom payments in the first hour of the virus outbreak, and its "money sucking" speed completely surpassed that of wannacry.

7. Bitcoin is a kind of virtual commodity, which can be obtained by calculation or sold on the trading platform
what currency is the most popular this year? I believe many people will answer: "bitcoin"
generally speaking, bitcoin is a kind of digital code, which is generated by a large number of calculations according to a specific algorithm. In theory, everyone can get bitcoin through calculation, which is compared to "gold digging" and "mining". According to the algorithm set by the founder of bitcoin, the total amount of bitcoin is limited, with only 21 million bitcoins. At present, 12.07 million bitcoins have been "g out"< However, it is not easy to dig out bitcoin. Lin Jia, a student of the school of economics and management of Beijing University of Posts and telecommunications, once made a special research. She said: "the performance of ordinary home computers is difficult to support the computing needed to" dig "bitcoin. There are special bitcoin" mining machines "on the market, and a high configuration one costs several hundred thousand yuan‘ Bitcoin is not only a high investment cost, but also a high technical threshold. The algorithm is very complex, so it is difficult for ordinary people to "dig" bitcoin by themselves. "
in fact, most people still buy bitcoin in cash. Bitcoin can not only be bought, it can also be sold. In some countries, bitcoin is even regarded as legal currency, which can be converted into real money and used directly for shopping. In China, some businesses announced that they would accept bitcoin payment<
if investors become the last stroke of drumming, they will only get a bunch of useless electronic symbols
recently, the central bank, MIIT, CBRC, CSRC and CIRC jointly issued the notice on prevention of bitcoin risk The notice stressed that bitcoin should be a specific virtual commodity, which does not have the same legal status as currency and cannot and should not be used as currency in the market. All financial institutions and Payment institutions shall not carry out business related to bitcoin
although a notice broke people's illusion of bitcoin becoming a currency in circulation, bitcoin still has a lot of fans. On December 16, the 24-hour trading volume of a bitcoin trading platform named okcoin in China alone reached 66225 bitcoins, with a trading volume of more than 300 million yuan
Why are people still so keen on investing in bitcoin? One of the important reasons is that many people think that bitcoin has a limited amount and can "maintain and increase value", and regard it as an investment tool like stocks and funds. In fact, investment in bitcoin was once very profitable. In the first four months of this year, bitcoin's value soared more than 10 times. In the short term, such a rapid rise has attracted a large number of follow-up speculators
bitcoin also falls sharply. On November 19, the price of bitcoin was fried to 8000 yuan, and then dropped to 2850 yuan on December 18, a month later
nevertheless, the bitcoin market is not in a slump, and even Lin Jia is going to "buy the bottom"“ A friend has bought bitcoin before and heard that he has made a lot of money, "said Lin Jia." I'm going to invest one or two thousand yuan to buy a few bits of bitcoin first. If I lose, I'll lose. Compared with the price of 8000 yuan, it may not be a high point now. Wouldn't it be good if we could make a profit? "
bitcoin charts, an international bitcoin website, shows that nearly 60% of bitcoin transactions recently come from the Chinese market. Many people share Lin Jia's "bottom hunting" mentality
however, the risk of bitcoin is not just the risk of price fluctuation“ Bitcoin is now more of an arbitrage tool than a payment tool, and its technical risk, security risk and regulatory risk are worrying. " Zhao Qingming, an adjunct professor at the school of finance, University of international business and economics, said frankly
first of all, from the perspective of the development history of the Internet, although the algorithm of bitcoin is complex, it is not impossible to be broken. Once broken, the whole system of bitcoin will collapse. Secondly, the private trading platform is not mature. Recently, a number of bitcoin trading accounts were stolen in Shanghai, with a loss of 640000 yuan. In addition, market regulation has not kept up. At present, the servers of many bitcoin trading platforms are built in foreign countries, and they are not registered in the domestic instrial and commercial departments, so it is difficult to protect the interests of investors< In Zhao Qingming's view, it is not advisable to buy and sell bitcoin with a speculative mentality: "bitcoin does not have the basic function of currency, unlike real gold and silver commodity currency, or paper currency credit currency with government credit support. Similar hype is not uncommon in Chinese history. Pu'er tea, Longjing and mahogany furniture also set sky high prices. If the investors who buy bitcoin become the last stroke of drumming, they will only get a bunch of useless electronic symbols. "

8. This news may not be true, because many people have been known as Nakamoto Tsung before, but in the end, it was not clear. Maybe it's a hype. Bitcoin was born in 2009, and its inventor is "Nakamoto Tsung" (pseudonym). In 2011, when bitcoin became popular, Nakamoto disappeared. Therefore, his identity has been talked about by the instry. But on Tuesday, wired magazine and Gizmodo published articles one after another, saying that all kinds of evidence show that Wright is Nakamoto
