What is going on with an emergency notification of extortion viruses in the National Internet Information Safety Center?

The National Network and Information Security Information Report Center emergency notification: At about 20:00 on May 12, 2017, the new "worm" type ransom virus broke out. At present, tens of thousands of computers in more than 100 countries and regions were infected by the extortion virus. Part of my country's Windows series operating system users have been infected.

IV computer users, please upgrade and install patch as soon as possible, the address is:
technet.microsoft/zh-library/security/ms17-010.aspx
windows 2003 and XP has no official patch. Related users can open and enable the Windows firewall, enter "Advanced Settings", disable "File and Printer Sharing" settings; or enable high -risk ports such as 445 and 135, 137, 138, and 139.

5 From May 12th, a worm malicious code based on the Windows network sharing agreement broke out worldwide. The cyber attack incident initiated by the blue "attack program, users can be attacked as long as they start the Internet. Within five hours, including Britain, Russia, Europe, and many domestic universities, internal networks, large -scale enterprise internal networks and government agencies' special network recruits, they can be filed for recovery documents by extortion and paying high ransoms, causing serious losses to important data.
The most terrible thing is that this is a worm virus split virus attack on the "Eternal Blue" leaked by the criminals using the NSA hacker weapon library leaked. The malicious code will scan the Windows machine that is open to the 445 file sharing port. It does not require any operations of the user. As long as you turn on the Internet, the criminals can implant ransomware, remotely control Trojan, and virtual currency mining machines in computers and servers.

The computer of a college student has a extortion virus, and the extortion content is too funny: request to pay the ransom ransom as soon as possible, otherwise the document will be deleted, and even the poor who have not paid the poor after half a year later Can participate in free decompression activities. It turned out that this was just a small scope of extortion software. I did not expect that the extortion software broke out in a large area last night. Many college students recruited and intensified.
