Regarding the ransomware "WannaCry" for the Windows operating system that appeared on the Internet on May 12, people's panic seems to have slowly subsided due to the introduction of many countermeasures and the release of Microsoft patches, and they have resumed their tense and orderly lives. . But is this thing really gone?
Event review
The virus that broke out on May 12 exploited a vulnerability called "Eternal Blue" (MS17-010) on the Windows operating system. The virus will scan the Windows system through the 445 port intrusion file, without any user operation. As long as the Internet is switched on, malicious programs such as ransomware, remote control Trojans, and virtual currency mining machines can be implanted in computers and servers.
Due to the above characteristics, on the day of the emergence, the virus has madly attacked hundreds of countries around the world with lightning speed, and the intranet network of many industries in China has also been infected on a large scale. The infected computer file is encrypted and can only be recovered by paying a ransom. The extortion is $300 to $600 worth of bitcoin. However, many people report that even if the ransom was paid, the documents did not recover.
The field of education is the hardest hit by this virus attack.
Xiaowei learned that the most serious virus attack was in the field of education and research. According to the data released by the 360 ​​Threat Intelligence Center on the morning of the 14th, as of 20:00 on May 13th, there were hundreds of thousands of machines infected by 29,372 organizations in China, including 4,341 educational and research institutions. disaster area.
In addition, according to the Chinese Education and Research Computer Network document managed by the Ministry of Education, from May 12 to 14, three days, 66 colleges and universities across the country were infected with the virus. At the same time, many college students reported that photos, documents, and audio and video files on their computers were locked and could not be opened.
It can be seen that with the development of national education informatization, new technologies such as big data, cloud computing, mobile Internet and Internet of Things have been widely used in education, and the network security threats and information security challenges facing the education industry. It is also becoming more and more serious, and information security in the education industry has become the most vulnerable industry in all industries!
