The first of the top 10 viruses in 2008, what was the virus in 2010

Tianjin, 22 Jan (Xinhuanet) -- The "2007 Report on China's Computer Virus Epidemic and Internet Security," officially released by network security manufacturer Jinshan a few days ago, pointed out that in 2007, new virus Trojans were launched at a "high speed," with as many as 283084 kinds of new computer viruses and Trojans, and the number of online game number theft Trojans "ranked" among the top ten Internet viruses in 2007 by virtue of the high infection rate of 8 13, and the "industrialized" invasion characteristics of viruses were particularly obvious.

In 2007, Kingsoft intercepted a total of 283084 new virus Trojans, an increase of 17 88 compared with 06, of which the number of new Trojans was as many as 118895, accounting for 42 of the total number of new Trojans. In 07, the growth rate of virus Trojans has slowed down compared with 06, but it is still in a state of substantial growth, and the total number is still very large.

In 2007, a total of 49.65 million computers in the country were infected with viruses, an increase of 18,15 compared with the same period last year, and the proportion of Internet users who had been attacked by viruses accounted for 90,56. Among them, Guangdong is still the hardest hit area by computer virus infection, with a total of 5705520 computers infected in 07, and it is also the only province with more than 5 million infected computers.

In 2007, the "industrial" invasion of the virus became more and more obvious. It is reported that the "industrial" means of intrusion have been widely circulated in hacker circles. The attacker fully automates the above attack processes, fully automating port scanning, remote intrusion, and Trojans, and the efficiency of grabbing broilers depends only on the performance and network bandwidth of the computer used to launch the attack.

In addition, the "process-based" attack of the virus and the Web2 0 of the virus spread were also particularly prominent in 2007.

In the security report released by Kingsoft, the online game number theft Trojan "squeezed out" the panda burning incense, gray pigeon, auto virus and other viruses with great influence in the year, and "ranked" the top ten Internet viruses in 2007.

Kingsoft anti-virus engineers said that in 2007, the sharp increase in online game users gave birth to a "boom" of number-stealing Trojans. The online game number theft Trojan is not a virus, but a kind of virus with a high degree of similarity, and a wide variety of variants, stealing the passwords of various online games, which is a product of the industrialization of Trojans.

Looking ahead to 2008, Kingsoft anti-virus engineers said that in 2008, the number of attempts at new platforms will increase significantly. The Vista virus will likely become the new favorite of virus authors. At the same time, when smartphones enter the 3G era, virus Trojan activities on mobile phone platforms will rise.

In addition, new technologies for anti-active defense or penetrating active defense will emerge, and cyber fraud will intensify.

Among the top 10 viruses in the first half of 2008, the top of the list was "online game thieves" and its variants.

The second half of the year is not out yet.

Problem description: What was the name of the world's first virus? Who wrote it? In what language?

What is the specific source program?

Analysis: Since American student Fried Cohen wrote the first computer virus for the purpose of testing computer security, the global computer virus Shenqin ushered in its 20th birthday this week, and there are currently more than 60,000 kinds of computer first viruses in the world, which have developed from the initial small trouble to users to a serious threat to the security of computers and networks.

Virus writers have begun to take advantage of the latest technology, and viruses are starting to spread more rapidly and cause chaos through the network. Cohen wrote the world's first computer virus while studying for his Ph.D. at the University of Southern California, loading the virus into a graphics software called a VD, which then hid in the VD software and spread through the computer system.

Cohen originally wrote the computer virus for experimentation, and he discovered that his virus could spread to all parts of the system in less than an hour, with the fastest rate being 5 minutes.

Cohen presented his findings at a computer security symposium on November 10, 1983, in which Cohen presciently stated: "Viruses can spread across computer networks as they do from computer to computer, and this will pose a widespread and rapid threat to many systems." ”

Computer viruses were first written against IBM computers, and one of the earliest of these was the "brain" virus, which emerged in 1986 and came from Pakistan, apparently to monitor piracy of their computer programs. With the advent of the "Brain" computer virus, viruses named "Lehigh", "Jerusalem", "Cascade", and "Miami" were also introduced.

Ebola virus.

Ebola haemorrhagic fever, an acute infectious disease, is caused by the Ebola virus, which is transmitted through physical contact. It is currently the most virulent viral disease known, with a case fatality rate of 50 90. The disease originated in the jungles of Africa and Asia. Also called Ebola virus disease.

In 1976, an unknown plague swept through 55 villages along the Ebola River in northern Zaire, killing more than 90 of its patients in horrific ways. In the same year, the disease-causing virus was first isolated from a patient in an Ebola-stricken village, hence the name "Ebola virus". The disease caused is called "Ebola haemorrhagic fever".

A Ugandan infectious disease specialist described the horrific conditions of death in people infected with the Ebola virus as "hemorrhages in and out of the body, necrosis and decomposition of organs, and the patient constantly spits dead tissue from his mouth." I felt like watching a big living person slowly and dissolve in front of me until it collapsed and died."

The problem is that after so many years of research, there is still no specific method or vaccine.

But if the bird flu continues to develop, it will be quite scary, and the virus will always evolve.

Cholera, plague, smallpox. In ancient times, a single outbreak of these plagues could wipe out seventy or eighty percent of the lives of people in the epidemic area!

The new coronavirus, the scope of the whole world.

a. The structural level of living systems includes cells, tissues, organs, systems, individuals, populations, communities, ecosystems, and biospheres.

b. The virus has no cellular structure, no organelles, and B is wrong;

c. The virus has no cell structure, and the host cell needs to be used to complete the life activities, and its protein is synthesized on the ribosome of the host cell, C is correct;

d. Viruses have no cellular structure and do not belong to prokaryotes

Hehe, I just like to say it.
