This computer virus broke out all over the world! Campus networks of many universities in China were hacked.
Cctv newsLast night, some college students in China reported that their computers were attacked by viruses and their documents were encrypted. The attacker said that the virtual currency equivalent to 300 dollars (about 2069 yuan) was needed to unlock it.

Many universities in China were attacked and students’ graduation thesis "fell"
At present, Weibo and WeChat, the official websites of many universities, have issued early warning messages, saying that campus networks and classmates’ computers of many universities in China have been infected with viruses during this period. Many students’ graduation thesis, graduation design and other important materials have been declared "occupied". Some colleges and universities have issued early warning information to remind everyone not to click on unknown links and install anti-virus software.
It is reported that,The virus is nationwide, and it is suspected to spread through the campus network, which is very rapid.At present, Hezhou University, Guilin University of Electronic Technology, Guilin Institute of Aerospace Industry, Ningbo University, Zhejiang University of Traditional Chinese Medicine, Zhejiang Gongshang University, Zhejiang Sci-Tech University, Dalian Maritime University, Shandong University and many other universities have been attacked by viruses.
Here, I would like to remind campus students in all regions to back up important documents to avoid extortion, especially for fresh graduates, and their papers must be backed up!
In addition, some gas stations owned by PetroChina in many places in China were suddenly disconnected at around 0: 00 today. At present, online payment methods such as Alipay, WeChat and UnionPay card cannot be used, so cash payment can only be used, and the refueling business of gas stations is running normally.
99 countries were attacked, and many operations in Britain were cancelled.
At present, 99 countries have been attacked, including Britain, the United States, China, Russian, Spanish and Italian. Avast, an anti-virus software manufacturer, said that the number of ransomware cases around the world has increased to 75,000, and it is still spreading rapidly.
Attacks have occurred in the United States, China, Japan, Russia, Britain and other important countries, with Russia being the most seriously attacked. The attacks on Britain are mainly concentrated in the National Health Service (NHS). At least 25 hospitals under the NHS have computer systems paralyzed and ambulances cannot be dispatched, which is very likely to delay patients’ treatment and cause life-threatening worries.
Who is attacking?
Some experts say that this kind of attack should take advantage of a loophole in the Microsoft system. The vulnerability was first discovered by the US National Security Bureau. The tools developed by the National Security Bureau were stolen by a hacker group called "Shadow Broker". Hackers also tried to sell them in an online auction. However, the hackers later decided to provide these tools for free, and issued an encrypted password on April 8 on the grounds of "protesting Trump".
Microsoft said yesterday that its engineers have increased the detection and protection against the virus. Microsoft also said that it is helping customers.
Five strokesTo protect you from ransomware
1. Back up your own files:The ideal storage place is an external mobile hard disk.
2. Be alert to emails, websites and applications:Be vigilant when opening unknown emails or browsing unfamiliar websites, and never download applications that are not certified by official stores.
3. Use anti-virus programs and constantly update software patches.
4. Never pay ransom:Paying a ransom to a hacker will encourage the hacker to be arrogant, and even if the ransom is paid, the infected file may not be able to return to normal.
5. Preventive measures provided by universities:
To install the latest security patch for computers, Microsoft has released patch MS17-010 at https://TechNet.microsoft.com/zh-cn/library/security/MS17-010.
Close ports 445, 135, 137, 138 and 139, and close network sharing.
It is suggested that users who are still using windows xp and windows 2003 should upgrade to window 7/windows 10 or windows 2008/2012/2016 as soon as possible.
