1. In the past day, 99 countries around the world, including China, have been attacked by ransomware, which covers windows computers of many public service organizations and indivial users
the NHS's computer files were locked, forcing them to cancel outpatient appointments and transfer patients; Other victims include Spain's largest telecom operator, Russia's interior office and FedEx, whose computer files are encrypted and inaccessible
in China, many colleges and universities, including Peking University, have been attacked, and the files on the students' computers connected to the campus network have also been encrypted and required to pay ransom
the so-called "ransomware" has no difference from extortion: after hacking through a computer vulnerability, hackers encrypt some files, then use the secret key to decrypt as a threat to ask the owner to pay "ransom"
this is one of the biggest network attacks at present. Avast, a security software company, said it had confirmed 75000 times, affecting countries such as Britain, the United States and Russia, among which Russia, Ukraine and Taiwan were the hardest hit areas
in this attack, the old windows systems are mainly attacked, including Windows XP, Windows 8 and windows server 2012. Microsoft said windows 10 users have not been attacked yet<
blackmail software attack, blackmail the user by encrypting the files on the computer image from: mspower
the computer interface of zhongzhao will show such a window to inform the user that the files on their computer have been encrypted and they must pay the ransom in the encrypted digital currency bitcoin
bitcoin should be chosen because it is difficult to trace. The attacker asked for $300-600
what happened to this blackmail software
since Friday, this blackmail software has attacked medical, banking, school and other public service institutions in many countries, but no hacker group has claimed responsibility for this attack
this blackmail attack is believed to be related to a previously leaked vulnerability in the windows system. In April, a hacker group named shadow brokers g up a Windows system attack tool, eternalblue, from the US National Security Agency (NSA). On the basis of this attack tool, the blackmail attacker added a self replication mechanism, which can be transferred from one attacked computer to another, but the attacker's information has not been determined yet
in this attack, extortion software disguised as invoice documents and recruitment related documents were spread in the email. But different from the common blackmail software, wanna virus can infect computer files without users opening e-mail or downloading. Because ransom is restricted to be delivered in encrypted digital currency bitcoin, the blackmailer's information is not as easy to be tracked by the police as credit cards and bank transfers
this attack not only attacks indivial computers, but also affects the whole network. British security architects give CNN an example: if an attacked computer is connected to the network of a cafe, the blackmail software will infect all the computers in the cafe
in China, blackmail software can attack the 445 port used for file sharing on campus network to spread. For example, the gas stations of PetroChina may be attacked because the payment system hosts without upgraded system are also affected. At present, these gas stations have been shut down< In an official statement on Friday, Microsoft said that it had released a patch for the vulnerability and that users who have opened windows update have been protected
in addition, for the key targets of this attack, including Windows XP, win8 and windows server 2012, Microsoft has also provided security updates on its official website
further proliferation was blocked by Tony B, a researcher at a security software company. The researcher from kryptos logic security controlled a website domain name and hard coded it into the blackmail software, which prevented wanna from further spreading, but the previously attacked computers were still affected
it's more about luck to find a way to stop. Tony B's job is to find ways to track different kinds of malware. His method is to track the domain names of servers that can control the malware
according to the spread of malware, he will find those unregistered server domain names related to malware, and then back track the malware to verify whether the spread of these malware can be controlled. He has registered hundreds of such domain names to control the malware
in this attack, he found a server domain name related to the blackmail software in the same way and registered it. Unexpectedly, he guessed the domain name of the server controlling the blackmail software
because the computer under attack can't decrypt the encrypted files by the user, the encrypted files can only be decrypted by the attacker. In the blackmail attack similar to this incident, the user can only strengthen protection, but can't solve it.

2. blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

The 5g signal tower project is real
2019 is an important year for the construction of 5g in Shaanxi Province. While China Telecom, China Mobile, China Unicom and China Tower jointly start 5g business, Shaanxi operators also start 5g business simultaneously, marking that Shaanxi has officially entered the 5g era. 5g commercial package will also be launched on November 1, 2019. Users who make an appointment in advance can quickly order 5g package without changing their card, number or registration
On the morning of November 17, the press conference of 5g infrastructure project of Shaanxi Mobile communication signal tower was held. The reporter learned that the project will be officially launched on November 18, with a planned construction period of three years and construction in three stagesat present, the project is planned to be carried out in three stages in three years. The first stage accounts for about 30% of the project share, mainly in various regions of Shaanxi Province to build 5g infrastructure framework; The second phase accounts for about 30% of the project share, mainly for the supplementary construction of base stations in various regions; The third stage accounts for about 40% of the project share, and further precise refinement of the project is completed
taking mobile phone radiation as an example, in actual use, the size of radiation is related to the distance between the mobile phone and the base station, the geographical environment around the user, the setting of the base station and other factors“ Generally speaking, the closer the mobile phone is to the base station, the smaller the transmission power and the less the radiation. " Xiang Ligang said
in addition, the construction of base station also faces a huge cost problem. Wang Xiaofei said that from the perspective of base station construction alone, instry experts estimate that China's investment in base station construction, including large base station and small base station, will reach several trillion yuan if 5g network is completed
and based on the current test results, the power consumption of 5g base stations is two to three times that of 4G base stations, and the number of base stations is large. The electricity cost is expected to account for more than 40% of the operation cost of 5g base stations, which is also a very noteworthy problem< br />
5. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million.
6. Hackers hacked, or encountered a liar master, they have a lot of telecom network liars, through some base station group email. In fact, you don't need to pay attention to these e-mails. You'd better change your password, encrypt some important e-mails and save important materials.
