China Business Daily / China Business Network (reporter Jiao Likun Wen / photo) Douyin, which has more than 600 million monthly active users, has been targeted by many lawbreakers, and the "dark war" between Douyin and black ash production (referring to telecommunications fraud, phishing websites, Trojan viruses, hacker extortion and other acts of using the Internet to carry out illegal and criminal activities) has been going on. On December 1, the Douyin Security Center team made its debut and revealed its "battle" with black and gray production.
Zhang Xisheng, a security risk control expert at Douyin, introduced at the scene that black and ash production has penetrated into all walks of life.
Black ash production means upgraded
When shopping online, I saw that the number of praise and sales of a store were very large, so I placed an order to buy, but when I received the goods, I found that the description did not match the facts; when playing the game, I found that the opponent could teleport through the wall, but this did not meet the setting of the game at all; playing the game of grabbing red envelopes in the live broadcast room, the red envelopes were always taken out as soon as they appeared, and the account that received the red envelopes every time seemed to be the same few...
In fact, behind these phenomena are often specialized black and gray production gangs. Zhang Xisheng, a security risk control expert at Douyin, said that these gangs use abnormal means for the purpose of profit, and make behaviors that violate the original intention of product design, causing a negative impact on the platform and user enterprises. For example, the bad experience encountered by the online shopping mentioned above may be that the store has purchased the brushing service and forged false praise and sales; and the red envelope in the live broadcast room may be robbed because the black and gray production gang used the tool software to grab the red packet.
Zhang Xisheng said that the development of black and ash production has become a mature industrial chain so far, with the characteristics of gangs, specialization, strong confrontation, and cross-industry. In particular, the technology and means of the black and ash production industry are also upgrading. In the video displayed on the spot, members of the black and gray production gang can use the "group control software" to control dozens or even hundreds of mobile phones, automatically follow, like, comment, and even automatically private messages and reply to user information.
Zhang Xisheng said that the black and gray production gang uses new technologies and new means to attack and infiltrate the platform, and the efficiency is 100 times that of traditional attacks, or even higher.
Douyin destroyed 25 black and gray production gangs in half a year
Douyin has been hitting black and gray production. According to reports, Douyin set up a security operation team as early as its establishment, and later upgraded to become a Douyin security center. The latest information shows that the Douyin Security Center intercepts and processes more than 1 billion illegal content and behaviors every day, including illegal registration, brushing volume, brushing powder, likes, and publishing illegal comments, videos and other types of content.
Since the beginning of this year, the Douyin Security Center has banned more than 1 million pornographic diversion and pornographic solicitation accounts, and more than 300,000 accounts have been banned in September alone. In the special crackdown on counterfeit celebrities that began in April, the Douyin Security Center banned more than 180,000 black industry cheating accounts, reset more than 60,000 counterfeit data users, and handled more than 4 million problem videos.
Data show that in the past four months, the Douyin Security Center has assisted local public security organs to crack down on 25 black and gray production gangs suspected of fraud and pornography, and criminally detained 87 people.
Zhou Ran, director of the Douyin Security Center, has participated in the crackdown on a number of black and gray production cases this year. She introduced on the spot that the current black and gray production behavior is usually to register, buy and sell accounts upstream, and then implement drainage on short videos, social media and other platforms, and implement fraud and spread pornography on social software platforms, and some will be monetized on e-commerce platforms.
"Technology + product + operation" three-pronged approach
In fact, compared with the problems encountered by users on the platform, the problems handled by the Douyin Security Center are equivalent to a huge iceberg under the sea, which is not only complicated and diverse, but also repeated and changeable. Especially in recent years, the use of emerging technologies and tools by black and gray production groups has further increased the difficulty of our work. Shuai Shuai, head of the Douyin Security Center, said that the Douyin Security Center has always adhered to the platform governance principle of "early detection, prior interception, reminder during the event, and after-the-fact pursuit", and governed the illegal and illegal acts of the platform through technical means, product means and operational means. It is reported that the Douyin Security Center has applied data security, artificial intelligence and other technologies to the black and gray production attack to build a three-dimensional defense system.
"The technology and means of the black and ash industry have been upgrading, and in the process of confronting them, we are also constantly upgrading our technologies and strategies." Zhang Xisheng introduced, "In the early stage, the Douyin Security Center used the vocabulary list, list and frequency control strategy to fight, and then established a decision-making engine and tool platform, and began to use platform-based tools to carry out more efficient confrontation and attack."
Zhang Xisheng demonstrated an anti-fraud solution "Shark Anti-Fraud System" at the scene, which can determine whether the account is a black and gray fraudulent account at the stages of account registration, login, and posting comment content, and implement corresponding measures. In addition, he said that the Douyin Security Center has set up a red and blue army attack and defense team to carry out industry research on black and gray production, hoping to discover the latest trend of black and gray production industry before criminals.
"Social issues and douyin platform issues coexist symbiotically. So we have always believed that platform responsibility should not be limited to the platform. In the process of platform governance, the Douyin team will consider the problem as much as possible, hoping that in the process of solving its own platform problems, it can also carry out cross-platform linkage attacks with more institutions to further solve social problems. Zhou Ran called on all sectors of society to work together to crack down on violations of laws and regulations
