In recent time, a mobile phone virus called "Kabir" spreads all over the world, causing close attention to people. Some experts have realized and called: If there is no powerful measures, the type of mobile phone virus will increase rapidly, the harm and impact range will further increase, and become an important issue for threat information security.
"Kabir" source is now unknown for less than a year of 15 subtypes
According to the US "Chief Technology Officer" website today, two mobile phones that were "Kabil" virus infected in San Monica in California recently recently. The Finnish Information Technology Security Company is verified that the two phones have infected the "Kabil" H-type and type I viruses, respectively. But experts still don't know how they are infected. The "Kabil" virus can send the infected file to other mobile phones through the mobile phone Bluetooth device to form a diffusion. It was first found in the Philippines in June last year that 15 subageds have been evolved, and its harm is increasingly serious.
The analysis of the "Coordination" magazine invoked information security experts said that the early subtype of "Kabir" can only make mobile phone quickly exhaust the battery, and only infect the Nokia 60 Series mobile phone operating system, but the new subtypes have been able to Infected three different mobile phone operating systems, and destroy the files stored by mobile phone and manipulate the mobile phone to make a common telephone number.
Experts warned that although there is not much example of the "Kabir" virus, the virus spread is not fast enough, but the trend analysis of the evolution will soon have more dangerous new varieties. Since the number of mobile phones has exceeded the computer, the hazard caused by mobile phone viruses will also be as serious as today's computer virus.
Three hierarchy
Since June, the international virus preparation group "29A" released the first mobile phone virus "Kabil", mobile phone viruses have quietly attacked worldwide, and currently spread to 12 countries including China.
Mobile phone virus is a computer virus with mobile phones to attack targets. It uses mobile phones as infected objects, with mobile network and computer network as platforms, through viral SMS, attacks mobile phones, resulting in mobile phone abnormalities.
The world's first mobile phone virus "VBS.Timofonica", found in Spain in June 2000. The virus will send insults to the system through the operator's mobile system.
In general, mobile phone viruses have hazards through three ways.
First, attack the phone itself system and affect its normal service.
This is the main attack method of mobile phone virus, mainly initiating attacks in the way "viral SMS". The user registers a SMS service with a virus program on the website that it will receive a virus SMS consisting of garbled and cannot operate the SMS because any operation can cause an abnormality such as shutdown.
The second is to infect other mobile phones through information, causing damage to the host. "Kabir" virus belongs to this type. "Kabil" virus can spread through the Bluetooth device of the mobile phone, so that the dyed Bluetooth mobile phone searches and transmits other Bluetooth mobile phones. When the virus occurs, "Caribe-VZ / 29A" is displayed on the screen. The battery of the poisoning mobile phone will be exhausted, and the Bluetooth function is lost.
The third is to attack and control the "gateway", send spam to the mobile phone, causing the network to run paralyzed. "Gateway" is a network and network contact link. If the mobile phone virus writer can find the gateway vulnerability in the mobile network, write a viral attack gateway, once the attack is successful, will affect the mobile network, so that all services of the mobile phone cannot work properly.
The spread is faster than the computer virus, the degree of harm is fierce
The mobile phone virus is actually a computer virus that is targeted by mobile phones, which is a world-new public hazard that occurs with the development of informationization.
Since the US computer experts showcase the first computer virus in November 1983, there have been more and more types of computer viruses, and the wavefront is getting wider and larger, and the harm is getting bigger and big. The economic loss of the US dollar.
With the wide application of computer technology in the field of mobile communications, mobile phones have become increasingly high, and computer viruses for mobile phones are born in 2000 and began to hazard mobile users. From a point of view, the phone is more attractive to viral manufacturers than the computer. The reason is as follows:
First, the mobile phone has a fast development, many people have many people, and the popularity is wide;
Second, the mobile phone is running on the communication network one boot, and the virus is more likely to spread;
Third, using mobile phones need to pay various fees, using viruses to make economic crimes is simpler and more concealed.
Due to the lack of system statistics, the extent of mobile phones suffered from virus attacks is difficult to quantify, but sporadic reports are constantly occurring worldwide.
Data of the Jinshan anti-virus center shows that from 2001 to 2004, domestic damages and viruses have increased by 2.5 times. A smart phone with Internet features increased, providing a more convenient channel for hackers to spread mobile phone viruses.
Some experts believe that the development speed of mobile phone viruses exceeds the traditional computer virus. Bascato, USA, Pascato, USA, to 2006, the severity of mobile phone virus issues will be comparable to today's traditional computer virus.
Researchers have simulated in the laboratory to assess the hazards that can be caused by mobile phone viruses.
Experiments show that the virus can be replicated by mobile phone number book. Virus is likely to get unauthorized users to obtain mobile phone passwords or access important data information stored in the phone.
Hackers may also utilize viruses to implement handling of mobile phones, call any call or send information.
In addition, the virus may also delete all the contents in the phone, or record each call.
Some experts believe that due to mobile phones involve personal privacy, mobile phone viruses will exceed the computer virus in information security.
Hacker games are terrible to attack more horrible
Historical experience shows that information security issues are most limited to technical levels, but with the development of informationization, it will inevitably be utilized by illegal and hostile molecules, threaten national security and social stability, including hacker attacks, harmful information online transmission and information war, etc. New information security issues.
According to the development law of information security, some experts predict that mobile phone viruses will be used by illegal and hostile homologs in addition to caused mobile phone function, and the mobile bank account will cause economic losses to users; to steal communication materials, threaten user personal security; pretending Authority and people have released false or harmful information.
These issues will eventually threaten national security and social stability.
Mobile phone anti-virus has not spread anti-virus function to become hot
At present, there are very few mobile phones have antivirus.
For ordinary mobile phone users, they can only be anti-virus, and they can also be killed by mobile phones. Therefore, don't open the text messages that you don't know, the strange text message is best deleted. Once the mobile phone memory has been occupied by the virus SMS and cannot be deleted, contact the mobile phone manufacturer and upgrade the phone motherboard program. Users who want to buy a mobile phone should understand which models of mobile phones have security vulnerabilities before buying. It is best not to buy such phones.
Industry has made a response
Nowadays, mobile phone manufacturers and software companies have improved vigilance on the spread of "Kabil" virus.
According to reports, Finnish Nokia has introduced a safer new operating system. Microsoft is increasing the safety of its mobile phone operating software. Also have companies intensify to develop mobile phone anti-virus software.
According to reports, Nokia has prepared two mobile phones in two built-in anti-virus software. Japan's largest mobile phone operator Domo is also ready to send anti-virus software through mobile phones.
It is predicted that mobile anti-virus technology will become a hot spot in the industry in the next few years.
It should be seen that like a traditional computer virus, mobile phone viruses are "defense, controllable, cure". Especially in the past decade, human beings have accumulated a large number of positive opposition experience in the process of struggling with traditional computer viruses, which facilitates controlling the hazard of mobile phone viruses within an acceptable range.
