1. What is
bitcoin? What's the use of Internet? On the evening of the 12th, the computer blackmail worm named "eternal blue" broke out on a large scale in the world. It is said that "eternal blue" has spread to more than 100 countries, including Europe, the United States, China, etc. according to incomplete statistics, there are more than 1 million computers in the world, most of which are local area networks of universities and scientific research institutions. It is estimated that in the past 24 hours, about 150000 people have paid ransom to hackers through bitcoin trading platform. If this estimation is reliable, the amount of bitcoin that hackers have obtained is about 600 million yuan. If there is no accident, more people will pay ransom in the future. The amount of blackmail is estimated to be more than 10 billion! First of all, bitcoin does not belong to any country, indivial or organization. It is an uncontrolled and decentralized currency. Kun Peng made a search on it. In fact, bitcoin has been used as ransom in the early years. The method has not changed much. It's all encryption and blackmail. The person in charge of F-Secure, a network security company, once said that the encryption and blackmail software has become their biggest headache. Once the computer is infected, not only the hard disk drive is encrypted, but every file will be invaded. Although such incidents have emerged one after another in the past, it's only that they didn't have as much impact in the past as this one. Besides, people like to forget most, so they are not well known and it's normal. For example, around 2013, hackers began to extort bitcoin by illegally encrypting users' PC data and personal information. In 2014, an Australian executive was harassed by hackers after he paid $14000 worth of bitcoin ransom for malware under the pressure of online hackers. In 2015, hackers launched a third cyber attack on three Greek banks and demanded 20000 bitcoins (worth 7 million euros) as ransom from each of them. In 2015, the police department in tuxbury, Massachusetts, was attacked by hackers, resulting in the computer unable to log in. In order to prevent the loss of important data, the police station finally paid 500 bitcoin "ransom" as required by hackers. In 2016, a hacker hijacked the network of the Hollywood Presbyterian Memorial Medical Center through software, paralyzing the operation of the hospital. The hospital decided to pay 40 bitcoins, equivalent to about 17000 US dollars, as a "ransom" to the hacker Kunpeng believes that hackers choose bitcoin mainly because it has the characteristics of decentralization, globalization and anonymity like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields. Moreover, bitcoin can be used to cash, which can be converted into the currency of most countries. Bitcoin investors generally believe that the reason why hackers choose bitcoin to pay ransom is that bitcoin not only has advantages over other traditional payment tools, but also is the best choice among other virtual currencies. Firstly, bitcoin has certain anonymity, which is convenient for hackers to hide their identities; Secondly, it is not subject to geographical restrictions and can collect money on a global scale; At the same time, bitcoin also has the characteristics of "decentralization", which allows hackers to automatically process the ransom of victims through programs. With the technical support of the network, the manufacture and issuance of bitcoin are not based on the trust of the central issuing institution, and the operations such as transfer and other transactions do not even need names. That is to say, to collect money with bitcoin, you don't need to open an account in the real name of a financial institution, and you don't need to go through any third-party institutions, such as the third-party payment that we use most at present. You just need to download and register an independent bitcoin wallet. If what the criminal extorts this time is not bitcoin, US dollars or other currencies, and what the criminal gives is not a bitcoin wallet address, but a collection account of a bank, the hacker may have been locked or arrested before receiving the money. Now you know, anyway, I don't need bitcoin. Please pay more attention
