The impact of global epidemic on China
in this global computer virus incident, mobile China also received a blackmail. Fortunately, the machine that received the email was a testing machine, which did not affect us. However, it's different for college students in the graation season. The thesis is locked, which is related to graation. So in the face of this outbreak of blackmail virus, how should we deal with it and what protective measures should we take<
first of all, let's understand the characteristics of this virus
the computer virus initiated by hackers will encrypt a large number of files on the system into files with. Onion suffix. After poisoning, they are required to pay bitcoin ransom to decrypt and recover the files, causing serious losses to personal data, and anti-virus software cannot decrypt these encrypted files. But we must not listen to the hacker's so-called "give money to decrypt" saying, because hackers do not necessarily keep their promises, in addition, bitcoin is expensive, and it is also a large number for ordinary users< Secondly, we need to pay attention to the background of the virus outbreak.
according to the domestic experts, according to the network security agencies, this is a virus attack event launched by lawless elements using the "eternal blue" leaked from NSA hacker's weapon library“ "Eternal blue" will scan windows machines with open 445 file sharing port, without any user operation. As long as the machine is turned on and connected to the Internet, criminals can plant blackmail software, remote control Trojan horse, virtual currency mining machine and other malicious programs in computers and servers
e to the previous outbreak of worms using port 445 in China, operators have blocked port 445 for indivial users, but the ecation network has no such restriction, and there are still a large number of machines exposing port 445. According to the statistics of relevant institutions, at present, more than 5000 machines in China are attacked by NSA "eternal blue" hacker weapons every day, and the ecation network is the hardest hit area
What are the coping methods
1. Close port 445, and you can search and query by yourself
2. At present, Microsoft has released a patch ms17-010 to fix the system vulnerability of "eternal blue" attack. You can install this patch for your computer as soon as possible
as for XP, 2003 and other Microsoft machines that no longer provide security updates, microblog professionals recommend using "NSA Arsenal immunity tool" to detect whether there are vulnerabilities in the system, and close the ports affected by the vulnerabilities, so as to avoid being attacked by blackmail software and other viruses
Tencent computer housekeeper adopts the technology of checking and killing Tencent cloud, which can forcibly check and kill the latest Trojan horse programs, keep the computer away from the threat of viruses, and protect your computer in real time. It can also protect the Internet pages, system files, USB flash drives, browsers, etc. some viruses even tamper with computer files, All of them can protect your computer from being threatened and give you a clean Internet environment.
specific steps:
1. General search and kill, open Tencent computer manager - virus search and kill
2. Search and kill in safe mode, restart the computer, press F8, the screen displays WinXP system startup menu, press the key to move to "safe mode with command prompt", enter; Find the anti-virus software inside the computer to kill the virus.
I think this is more serious than the loss, but it should have little impact on our real currency. Because the two are not related . The currency of the virtual world is a game created by capitalists in order to converge the wealth of people in the real world. But no matter how we ordinary people speculate, we can't change the fate of these capitalists. They often dominate the changes in the war situation, turning their hands into clouds and covering their hands with rain. But no matter what they do, it should have little impact on the real world currency, otherwise governments will not allow them to exist
Therefore, changes in the bitcoin market will not affect the value of our real currency or other aspects. Even if there is, the governments of various countries will also vigorously suppress and try to rece the impact in this regard, so we should relax our mindsame
the association added: "other factors that affect the price of gold."
the world gold association said. There is an indirect positive relationship between these markets and interest rates, that is, the periodic rise of interest rates is usually accompanied by the increase of economic growth and consumer spending
the world gold association said. As of December 31, the real yields on three-month and one-year treasury bonds were - 0.73% and - 0.05%, respectively. Since 2008, the Federal Reserve has kept the federal funds rate close to zero
although the Fed was initially expected to raise interest rates for the first time in a decade in June this year, a series of mixed economic data, low inflation rate and dovish comments on the US economic growth rate issued by Fed chairman Yellen delayed the schele of raising interest rates, including some factors positively related to economic growth, It emphasizes that gold is an important diversified asset and a portfolio asset for risk management. "
in terms of investment demand, gold will continue to be a diversified asset
the World Gold Council said: "even when the nominal interest rate rises to 4%, gold has been quite effective in diversifying the investment portfolio and recing the risk of real interest rate, and it is not very sensitive to the change of interest rate in the United States. This helps to increase the demand for gold, as some investors will use gold to supplement bonds when managing equity risks and diversifying their portfolios. The impact of the US dollar interest rate increase on gold is the same as that of bitcoin, and the US Federal Reserve interest rate increase may not have the adverse effect on gold price as many people think
the relationship between gold prices and interest rates is more complex than it appears and more fragile than in the past, the World Gold Council said in a report on Thursday. In addition, demand for jewelry and technology is largely Pro cyclical, prompting investors to turn to profitable assets
according to the World Gold Council, the percentage is 0.6%
according to the association, the following is the impact of US dollar interest rate increase on gold. The view that US interest rate increase affects gold price is not as strong as before, because this situation is largely based on the market's analysis of gold price and interest rate performance from 1970s to 1980s. At that time, the economy was very different from what it is now< According to the World Gold Council, the gold market is also different:
the World Gold Council (WGC) claims that "the interest rate increase will not improve the prospects of fixed income assets. The demand for jewelry and technology accounts for nearly 60% of the annual demand for physical gold and is far below the threshold level. Over the past decade, demand for gold in developed markets has fallen from more than 60% in the 1970s to less than 30%. Emerging market demand for gold accounts for 70% a year, as stocks and bonds are likely to provide below average returns over the next few years. "
in the past 12 months. This role is becoming increasingly important. At the current yield level, the rising space of bonds may be limited, so it is not as effective as gold in easing equity risk
all kinds of signs make us dollar credit system full of uncertainty.
Bitcoin fell to 58000 yuan and 180000 people burst their positions. The affected groups are:
1 2 3 bitcoin, as a virtual currency in emerging instries, has attracted many people's attention. After bitcoin's sharp rise, the fluctuation began to increase, which caused fatal harm to many people. Bitcoin fell to 58000 yuan and 180000 people burst their positions. The affected groups were mainly those who increased their positions at a high level. The cost of these people was relatively high, and a little fluctuation would lead to big losses; At the same time, people who buy bitcoin with leverage or financing have weak ability to resist risks, and violent fluctuations will lead to their positions bursting. They should be the group most affected and the group with the most serious losses among the positions bursting groups; Finally, the trading maniac, keep chasing up and down, this group influence is also relatively large the people who chase up and down may not be as miserable as the above two groups. However, with a large number of transactions, the people who chase up and down every day will also suffer losses. This kind of thing consumes a lot of energy, but the loss of money also has a greater impact on them, and they are also a relatively influential group
Extreme weather now has a new group of victims - digital money diggers. Last week's heavy rain in Sichuan and the heat wave in Europe have affected the global bitcoin computing power. At the same time, extreme weather also gives us a glimpse of the impact on (the world) if China successfully expels the bitcoin mining instry
like other governments, Beijing is also worried about the huge energy consumption of virtual currency exploitation. According to authoritative statistics, the global electricity consumption for bitcoin mining can meet the domestic electricity consumption of 6.5 million American households. Although some analysts doubt the impact of China's bitcoin mining on the global virtual currency computing power, there is no dispute that China's miners still dominate the field of digital currency mining
