Starting on the 12th, a computer virus called WanaCrypt0r 2.0 (literally translated by WanaCry and supposed to be "want to cry") broke out and attacked many Windows users, and the incident took place in 99 countries.
If you inadvertently tap suspicious emails, unscanned attachments, etc., you will be waiting for: all computer files will be encrypted and locked, and virus-producing hackers will also modify desktop wallpaper and pop-up windows. , Tips for the infected owner (the content of the virus suggestion may even be translated into different languages ​​depending on the region): Bitcoin worth $300 is required to be paid within a specified period of time in order to rescue the person, double the timeout, and reject the computer. The files in may be completely emptied.

It seems that the creators of the virus, in addition to the fun of destruction, are even more inclined to extortion.
Where does the virus come from?
A website called intel.malwaretech.com lists real-time monitoring lists of infectious events around the world. (https://intel.malwaretech.com/WannaCrypt.html) In the lower left corner is a rolling reality of infection cases across the country. Actually, computers in Europe, the United States, and China are the most recruited.
(Infection around the world)
The United Kingdom may be the source of the outbreak of the WannaCry virus. The infection is the most serious after the infection. At least 16 hospitals using the Windows system were attacked and many cases requiring surgery were cancelled.
However, the source of the WannaCry virus has not yet been clarified. A number of professionals pointed out that the Windows system hacking tool Eternal Blue (code-named “permanent blueâ€) is the original prototype of this virus, and the Eternal Blue designer is the notorious “Prism†"The promoter of the plan is the National Security Agency (NSA).
How to prevent?
Microsoft is not unaware.
Prior to this, Microsoft released a vulnerabilities patch for “Eternal Blueâ€: MS17-010, IT home also cited a Microsoft spokesperson’s statement saying: Microsoft has released Win32.WannaCrypt against malware Rensom. However, a considerable number of users have used XP systems or older systems, or have closed the Microsoft upgrade push, resulting in PCs operating under high-risk conditions.
In addition, the WannaCry virus attack vulnerability is achieved through Microsoft's Windows operating system network ports (such as 445,135,137,138,139 ports, etc.) and network sharing and other ways to achieve infection and attacks. This also explains why China has become the main victim of this virus attack. In China, the Education Network has become a hard-hit area because it did not close port 445.
Don't worry, it's not so scary
First throw a conclusion: For the average user, if you upgrade in time, things are not so terrible.
First, users of non-education networks do not have to worry that due to the limitations of ordinary telecommunication networks and wireless routers, viruses cannot infect your PC through the relevant open ports;
Secondly, so far, there have been "Gek's Bay" and other public numbers have already pushed a lot of books banned 445 ports, if you are an education network users, please disconnect the network and change the computer settings according to the tutorial;
Third, if you have closed the upgrade of push Windows 10 or Windows 7 users, it is recommended to open the upgrade program as soon as possible, accept the Microsoft security patch push, older Windows XP users, please give up the feelings, upgrade the system ~
In short, although many technology media and the public number have done their best to excel, in fact, if you usually guard properly, you don't need to be afraid. If you are using a Windows 10 system, you don't need to worry about it. What you hate most is that every time you power on a forbidding forced upgrade, Microsoft is protecting you from the sudden virus damage.
PS. This article was completed with an upgraded Windows 10 system.
