According to the criminal law of the people's Republic of China, the punishment for illegally invading others' computers is as follows:

the criminal law of the people's Republic of China stipulates:

Article 285 [crime of illegally invading computer information system; Crime of illegally obtaining data of computer information system and illegally controlling computer information system; Whoever, in violation of state regulations, intrudes into a computer information system in the fields of state affairs, national defense construction or cutting-edge science and technology shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention

Those who, in violation of state regulations, intrude into a computer information system other than the provisions of the preceding paragraph, or use other technical means to obtain data stored, processed or transmitted in the computer information system, or illegally control the computer information system, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention and shall also, or shall only, be fined; If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and shall also be fined

Those who deliberately make or spread destructive programs such as computer viruses, which affect the normal operation of the computer system, and have serious consequences, shall be punished in accordance with the provisions of the first paragraph

It is stipulated in the

"explanation on Several Issues concerning the application of law in handling criminal cases endangering the security of computer information system":

article 1: illegal acquisition of computer information system data or illegal control of computer information system has one of the following circumstances, It should be recognized as "serious circumstances" as stipulated in the second paragraph of article 285 of the criminal law: (1) obtaining more than 10 groups of identity authentication information of payment and settlement, securities trading, futures trading and other online financial services

(2) obtaining more than 500 groups of identity authentication information other than those in Item (1); and

(3) illegally controlling more than 20 computer information systems

Article 8 if a crime of endangering the security of computer information system is committed in the name or form of a unit and meets the standard of conviction and sentencing as stipulated in this interpretation, the person in charge who is directly responsible and other persons who are directly responsible shall be investigated for criminal responsibility in accordance with articles 285 and 286 of the criminal law

5. The crime of illegally intruding into computer information system refers to the act of intruding into computer information system in the fields of state affairs, national defense construction and cutting-edge science and technology in violation of state regulations. According to the criminal law, the offender shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention.

6. Strictly speaking, illegal intrusion refers to the behavior of browsing, viewing, creating, changing and deleting the target without authorization. So I was convicted of trespassing
sentencing: it depends on which instry the company is and how much impact it has on the company. Generally, crimes committed by state-owned companies (such as military, media, finance, etc.) will be very serious, no matter whether they have impact or not
before the court convicts a general company, as long as the company does not investigate, it is basically OK. If the company is investigated, it is generally more than three years and less than seven years

7.

Yes

because they violate other people's system privacy, they will face punishment. So I think hackers will certainly cause some damage if they invade other people's computer systems. If the circumstances are serious, they will face some forms of punishment

First, this kind of illegal intrusion, whether other people's computers are illegal< p> This kind of illegal intrusion into other people's computer system is definitely an illegal act, because according to the criminal law of the people's Republic of China, it is pointed out that if there is illegal access to computer information system data, there is a provision of fixed-term imprisonment. Therefore, if we are not close to people, we should try not to let others invade our computer system, and the invasion of other people's computer system will lead to the disclosure of our personal privacy, so it is very dangerous

summary. By analyzing whether this kind of illegal intrusion into computer is illegal behavior and how to prevent the intrusion of hackers, we have a deep discussion. So when we have such a thing, we should analyze how to solve it. If you have any good ideas and opinions, please leave a message below

1. According to Article 285 of the criminal law, "the crime of illegally intruding into computer information system" refers to the act of intruding into computer information system in the fields of state affairs, national defense construction and cutting-edge science and technology in violation of state regulations

the object of this crime is the security of the important national computer information system, and the object of the crime is the computer information system in the fields of national affairs, national defense construction and cutting-edge science and technology

in the objective aspect, it is shown that it violates the national regulations and invades the above three kinds of computer information systems. The subjective aspect can only be intentional, that is, knowingly intrude into such system. Those who commit this crime shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention

According to Article 286 of the criminal law, the crime of destroying the computer information system refers to the operation of deleting, modifying, adding or interfering with the functions of the computer information system in violation of the state regulations, resulting in the abnormal operation of the computer information system or deleting, modifying or adding the data and Application programs stored, processed or transmitted in the computer information system, Or deliberately making and spreading destructive programs such as computer viruses, which affect the normal operation of the computer system and have serious consequences

The object of this crime is the state's management system of computer information system. The objective aspect is that the actor violates the national regulations, destroys the computer information system, and has serious consequences. The subjective aspect can only be intentional. Whoever commits the crime shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention; if the consequences are especially serious, he shall be sentenced to fixed-term imprisonment of not less than five years

< H2 > extended materials

to distinguish between crime and non crime, it should be noted that the establishment of this crime is for the special protection of computer information system security in the fields of national affairs, national defense construction and cutting-edge science and technology. Only by intruding into the computer information system in these fields can it constitute a crime

the invasion of computer information system in other fields shall not be regarded as this crime. Although this crime is an act crime, if the circumstances are obviously minor and the harm is not great, it can not be punished as a crime

The important departments of the country have generally established their own computer information systems. The normal operation of these computer information systems plays a very important role in ensuring national security, economic development and protecting people's lives and property

however, once these important computer information systems are illegally intruded, it may lead to the destruction of important data or the leakage of some important and sensitive information, which may not only proce a disastrous chain reaction in the system, but also cause serious political and economic losses, and even endanger the safety of people's lives and property

It is necessary to crack down on this kind of illegal intrusion into national important computer information system

9. The 21st century will be an information age with computer network as the core. Digitization, networking and informatization are the characteristics of the 21st century. Computers are playing an increasingly important role in people's work, study and life. With the rapid development of information technology with "computer network" as the core, the network is improving the work efficiency and quality for state organs; While bringing huge economic benefits and unlimited business opportunities to enterprises, a new criminal term computer crime has emerged. As a developing country, our country has lagged behind in legislation against this high-tech crime, and is basically in a state of being unable to abide by or having laws to abide by in terms of computer network management and computer crime. In the face of the difficulties in finding, capturing, obtaining evidence and determining the nature of computer crimes, it is an urgent and long-term problem for the judicial department to deal with computer crimes. In the criminal law of our country, the crime of destroying computer information system and the crime of illegally intruding into computer information system are included in the crime of disrupting social management order, which shows our country's firm attitude in cracking down on computer crime. As a computer practitioner, the author is well aware of the serious consequences of computer crime. In this paper, the author talks about some superficial understanding of the harm of this kind of crime, the source of the object of crime and the omission of this kind of crime in the criminal law, so as to achieve the purpose of casting a brick to attract jade< With the rapid development of computer technology, information network has become an important guarantee for social development. Information network involves many fields such as government, military, culture and ecation. Among them, many of the information stored, transmitted and processed are important government macro-control decision-making, commercial and economic information, bank funds transfer, stock and securities, energy resources data, scientific research data and other important information. There are a lot of sensitive information, even state secrets. The harm of computer crime is mainly reflected in two aspects: one is the loss of state secrets, trade secrets and other documents; The second is to destroy the computer system maliciously. China's network instry is developing rapidly. According to incomplete statistics, there are 6.7 million computers and 16.9 million Internet users in China. The proportion of Internet users in China has increased by more than 100% every year. The total number of Internet users has exceeded 15 million. Online banking, online shopping and other e-commerce are developing rapidly. There is an unprecedented upsurge in the application of Internet technology in government and enterprises. Along with the rise of the network, computer crime cases are also rising sharply, computer crime has become a common international problem. According to the report of the Federal Bureau of investigation, computer crime is one of the largest types of commercial crime, the average amount of each crime is 45000 US dollars, and the economic loss caused by computer crime is as high as 5 billion US dollars every year. Most of the computer crimes have the characteristics of instantaneity, wide area, specialization and space-time separation. Usually, it is difficult for computer criminals to leave criminal evidence, which greatly stimulates the occurrence of computer high-tech crime cases. With the rapid increase of the computer crime rate, the computer system, especially the network system, is facing a great threat, and has become one of the serious social problems. According to a joint survey by the computer security association of the United States and the Federal Bureau of investigation, only 53% of enterprises in this country have been infringed by computer viruses, and 42% of enterprises' computer systems have been illegally used in the past 12 months. According to a Pentagon research team, the United States has been attacked as many as 250000 times a year. For example, Russian hacker Vladimir Levin and his partners launched a series of attacks on Citybank Bank of the United States from the Internet computer of a small software company in St. Petersburg, stealing 11 million US dollars from Citybank bank's computer host in New York by means of electronic transfer. With the rise of the computer network, the "computer virus" that comes with it makes people smell "poison" and turn pale. The economic loss caused by the outbreak of computer virus every year is immeasurable<

Second, the classification and motivation of computer crimes

hacker originally refers to a computer fan who is very familiar with computer programming technology and is keen on compiling new programs in the field of computer programming, but now it has graally evolved into a person who "invades" the computer program system without permission, or maliciously destroys the computer program system To compile the pronoun of computer virus. Computer hackers are the main source of computer crimes. Generally speaking, the behaviors of hackers entering computer system can be divided into the following categories: one is "hacker's illegal invasion" to destroy computer information system; Second, making, ing, spreading and consulting harmful information on the Internet, such as spreading computer viruses and pornographic images; Third, the use of computers to implement financial fraud, theft, corruption, misappropriation of public funds; The fourth is the illegal use of computer resources, such as embezzling accounts, stealing state secrets or business secrets; Fifth, the use of the Internet to intimidate, blackmail and other crimes. With the increasing novelty and concealment of computer crime, there will be many other forms of crime in the future. From the current computer crime cases in China, the suspect is generally young student who is proficient in computers. The author believes that there are two criminal motives: first, the actor is not out of malice, but with fun or show their own computer technology expertise, the invasion of other people's computer system as a challenge to their own ability, after the invasion of the system does not implement destructive action and exit, can be called a non malicious intruder. Second, the purpose of the actor's intrusion into the computer system is to steal business intelligence, data or state secrets in intentional violation of state regulations; Or to show their ability and make, spread computer viruses and other destructive programs, resulting in system paralysis, such hackers can be called malicious intruders< Third, China's "criminal law" on computer crime

1. Article 285 of the criminal law stipulates the "crime of illegally invading computer information system", which refers to the violation of state regulations, invading the computer information system in the fields of state affairs, national defense construction and cutting-edge science and technology. The object of this crime is the security of the important national computer information system, and the object of the crime is the computer information system in the fields of national affairs, national defense construction and cutting-edge science and technology. The objective aspect is to violate the national regulations and invade the above three kinds of computer information systems. The subjective aspect can only be intentional, that is, knowingly intrude into such system. Those who commit this crime shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention< According to Article 286 of the criminal law, "the crime of destroying computer information system" refers to the operation of deleting, modifying, adding or interfering with the functions of computer information system in violation of state regulations, resulting in the abnormal operation of computer information system, or deleting, modifying or adding the data and application programs stored, processed or transmitted in computer information system, Or deliberately making and spreading destructive programs such as computer viruses, which affect the normal operation of the computer system and have serious consequences. The object of this crime is the state's management system of computer information system. The objective aspect is that the actor violates the national regulations, destroys the computer information system, and has serious consequences. The subjective aspect can only be intentional. Whoever commits the crime shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention; if the consequences are especially serious, he shall be sentenced to fixed-term imprisonment of not less than five years< In modern life, computer has become a very important tool for people in information exchange and daily work. To ensure the normal operation of computer information system is of great significance to the stability of normal social order and the development of social economy. Our country has raised the punishment of computer crime to the height of punishment. From the above two crimes, the punishment is not heavy, but also shows the punishment strength and determination of computer crime in our country. However, e to the lag of the formulation of the law, there are certain one sidedness and limitations in the punishment of this kind of crime in judicial practice

1. The two crimes cannot cover all the behaviors of computer crimes. For example, in the case of the Shanghai Hotline, Yang was arrested by the public security organ for illegally using the "Shanghai Hotline" for more than 2000 hours because he broke into eight servers of the "Shanghai Hotline" and cracked the accounts and passwords of most of the staff and more than 500 legitimate users, including the super user accounts and passwords of two servers, He was arrested for the crime of destroying computer information system. Later, the public security organs changed the compulsory measures from arrest to l. The case is a typical "three dissimilarities" case. The reasons are as follows: (1) Yang does not constitute "the crime of illegally invading the computing information system". According to the criminal law, what Yang invades is the information system of the network service provider, not the fields of state affairs, national defense construction and cutting-edge science and technology. The object of the crime is different from that of the crime, Therefore, it does not constitute the crime 2) Yang does not constitute a "crime of destroying computer information system.". According to the provisions of the crime, although the actor has the ability to delete, modify and cause network paralysis, he has not implemented the behavior. Even if he has implemented the behavior, he must achieve the "serious consequences" stipulated in the criminal law before he can be investigated for responsibility 3) Yang does not constitute theft. According to article 287 of the criminal law, Yang's behavior is essentially the same as stealing long-distance telephone and mobile number. However, in judicial practice, it is generally believed that the object of such illegal behavior is communication users, not communication service providers, namely Internet service providers (ISPs), If the interpretation is expanded, there is no clear legal provisions or judicial interpretation. According to the principle of no crime without explicit provisions in the law, we can only draw the conclusion that Yang does not constitute theft

2. There is no accurate standard to define the term "serious consequences". For example, what is the accurate definition standard of "serious consequences" in the crime of destroying computer information system?, What kind of consequences are serious? For another example, in the first case of hacking into the securities network, Zhang illegally intruded into the computer system of the securities company in order to help his friends speculate in stocks and obtain insider information, ing the detailed information of the customer's account number and fund balance. After Zhang was arrested, the judicial department found Zhang "innocent" after examination. As far as this case is concerned, there are some similarities with the previous case. Does Zhang constitute the crime of stealing trade secrets? The focus of the debate is that according to the criminal law, the crime of stealing trade secrets should be constituted only by causing heavy losses. How to define the meaning of "serious consequences" and whether the serious consequences are based on the actual property losses. The author agrees with the judicial organ's determination of "not guilty" because Zhang has used computer to steal business secrets
