Recently, Yang Jie, the person in charge of the case and director of the Intellectual Property Procuratorate of the People's Procuratorate of Nanshan District, Shenzhen, said in an interview with reporters that as the Internet is becoming more and more in-depth, such cases are growing explosively. Many hackers are "self-taught" and they have a clear division of labor. Compared with traditional crimes such as theft, this new type of crime is more harmful, and in serious cases, it may cause losses of over 100 million yuan. "At present, the relevant judicial interpretations and many case handling methods are still lagging behind, and the professional ability requirements for the case handlers are getting higher and higher. The relevant case handling concepts and case handling ideas must be updated faster to keep up with the situation." Yang Jie said.
Game company server is attacked and paralyzed
Sorry, the server is out of order. We are repairing it. Please wait a moment and try again. On the weekend of February 26, 2017, when playing online games such as doulandlord, many users suddenly found that the game page could not log in. Soon, the staff of the game company found out the reason, the server was attacked by "DDoS", and the attack traffic peak reached 450g.
The so-called "DDoS", that is, "distributed denial of service", refers to the use of client / server technology to combine multiple computers as an attack platform to launch a network attack on one or more targets, thus multiplying the power of denial of service attacks. It is generally understood that when a hacker grasps a large number of computer resources and commands them to visit a website or IP address at the same time, the website will be paralyzed because it cannot carry a huge amount of visits.
After a wave of large-scale cyber attacks, game companies received a significant email. The email pointed out that the server defense of game companies is not large enough. If there is a need to improve the defense, you can contact them through the contact information in the email. The game company did not respond to this. On March 15 and March 16 of the same year, the same attack reappeared.
As the cloud service provider of the above-mentioned game companies, Tencent has also received feedback from the game companies. "We have monitored a large source of hacker attacks, which has caused great harm to our business, especially some enterprise services in the cloud, which have been greatly affected." Zhu Jinsong, general manager of Tencent's security management department, said that Tencent discovered some suspicious clues through technical analysis of the source of the attack and called the police as soon as possible.
"Dark night team" launched a cyber attack in Laos
In early 2017, Yuanmou and yaomou were employed to set up a hacker organization called "night group" in Laos. Mr. Yuan, Mr. Yao, Mr. Li and Mr. Zhou successively went to Laos from home to live in a closed management villa and received wages ranging from 6000 yuan to 20000 yuan per month.
The division of labor within the "night group" is clear. Among them, some are responsible for providing funds, designating targets for attack, some are responsible for daily management, receiving instructions from superiors, some are responsible for computer maintenance, software debugging and other related technical support, others are responsible for IP analysis, server "attack" and other work in the organization, and even some financial personnel are responsible for paying salaries to personnel in the organization and engaging in logistics work. &To launch a network attack, hackers must control the "chicken" in the early stage. The reporter noted that in the "dark night group", someone was specially responsible for "receiving quantity" from network hackers (pointing to domestic hackers who illegally purchased the control right of "chicken" server), and testing the amount of attack traffic of the received "chicken" server.
After acquiring a large number of server resources, the "Night Team" basically has the ability to launch "DDoS" attacks. Members use Trojan software to control multiple "chickens" from "revenue", which can continuously attack specific target IP, block the network, and seriously lead to the server network paralysis of the target IP.
This also appeared above one scene, the server of game company is paralyzed, the user cannot open the page or drops the line frequently. &Nbsp; for the purpose of the "dark night group" launching the network attack, Yang Jie said that the organization mainly carried out "DDoS" attacks against the servers of online chess and card games in China, the purpose of which is to let these game companies purchase their high-level defense services and use their designated or agent servers, similar to "thugs", which is also the reason why they sent e-mails to the game companies after the attack.
11Six members were punished for the crime of destroying computer information system
After receiving the alarm, the public security organ shall file a case in time. After discovering the abnormality, the members of the "night group" disbanded the group and returned to China in batches. Around July 2017, the public security organs successively arrested many people involved in the case. In order to better guide the investigation, the procuratorial organ also intervened in advance.
"During the period of review and prosecution, the suspects began to plead not guilty." Yangjie recalled that after returning for supplementary investigation at that time, he sorted out the whole attack chain, connected the person who provided the attack resources with the person who purchased the attack resources through relevant evidence, clarified the relationship between the attack behavior and the consequences of the damage, and finally all the 11 suspects pleaded guilty.
In March 2018, Nanshan District Procuratorate of Shenzhen city initiated a public prosecution against Yao, yuan and other 11 people. Prosecutors allege that the "dark night team" used 14 control end servers of "revenue" to continuously attack Tencent cloud servers on February 26, March 15 and March 16, 2017, resulting in many online game companies being blocked IP and unable to operate normally. &According to Nanshan District Procuratorate of Shenzhen City, 11 people, including Yao and Yuanmou, violated the state regulations and used "DDoS" attacks to interfere with the functions of computer information system, resulting in the abnormal operation of computer information system, with especially serious consequences. Their actions violated the criminal law and should be prosecuted for their criminal responsibility for the crime of destroying computer information system.
"The criminal facts accused by the public prosecution agency are clear, the evidence is true and sufficient, and the charges are confirmed." Based on this, the court found Yao and Yuan guilty of destroying the computer system and sentenced them to two years in prison respectively. Li and nine others were sentenced to fixed-term imprisonment ranging from one year to one and four months respectively. "The industrial chain of online black industry is becoming increasingly complex, and the trends of intelligent, professional and cross-border criminal means are becoming increasingly obvious. At the same time, the new case situation has also brought challenges to the application of specific laws."
Zhu Jinsong said that the successful judgment of the "night group" case made the hacker groups subject to legal punishment, which caused great shock in the industry, and hoped that the case could play a good exemplary role. With the development of economy, the demands of new economic forms for judicial governance are increasing, and we expect to have better legal weapons to protect the development of Internet industry.
