It is worth noting that,
Is there still a black industry chain that cracks surveillance and pays to spy on privacy?
In addition to public place cameras, are home cameras also at risk of being hacked?
Cutting off the black industry chain cannot stop at the end of the attack, but also needs to be rectified throughout the process.
Recently, Bilibili Barrage Network (hereinafter referred to as Station B) has attracted attention for a large number of surveillance videos in public places.
It is understood that most of the uploaded videos are mainly schools, hospitals and hotels, and at the bottom of the videos, the comments are mostly comments on the women who appear on the camera, and the content is unsightly.
In response, the official response of Station B said that it has organized investigations, removed relevant content from the shelves, and banned accounts that uploaded relevant content.
Why are private videos uploaded to the Internet?
Why can surveillance videos in public places be uploaded through private accounts?
Are there loopholes in the platform audit mechanism?
Reporters conducted an investigation.

Surveillance video streaming
Relevant content removed from station B and titled
On January 16, a Douban netizen posted a set of video screenshots from Station B, saying that some users had uploaded a large number of videos from a monitor's perspective on Station B, including school classrooms, hospital front desks and other places. It was suspected that some public places had been cracked. surveillance cameras.
At the same time, in the pictures posted by the netizen, many people left comments below the video, the content pointed directly at the women in the video, and the words were very unbearable.
The netizen also added a text to exhort everyone to be careful, saying that the video black production is not only in the B station, "The main reason is that this black production may have already formed, the purpose of their video should be to attract people into the paid group, there may be supporting packages. A whole set of monitoring for a school, from the office to the classroom." Soon, the official of station B responded conveniently that they had organized the investigation, removed the relevant content, banned the account that uploaded the relevant content, and reported the account information to the competent authority.
Video black production
Personal privacy is lost, cracking, surveillance and video surveillance coexist
Through investigation, the reporter found that the video black production mentioned by the above-mentioned netizens is mainly manifested in that criminals steal user videos equipped with networked monitoring equipment through technical means, or use pinhole cameras and other equipment to secretly photograph others in daily life, and then Using the audit loopholes of the short video platform, the illegally obtained videos are spread on the Internet, so as to find target customers and make profits.
Past cases have shown that illegal software is an important tool for stealing surveillance video, that is, criminals use software to scan cameras in the IP segment, crack the camera login password, and invade control.
Zhang Jiaqi, a senior engineer at the National Internet Emergency Response Center, once publicly stated that because many camera passwords are not changed, the initial default username and password are used, so once they (illegals) obtain these camera IDs, they can watch a large number of cameras. real-time screen.
According to a judgment issued by the People's Procuratorate of Dongcheng District, Beijing, from June to July 2017, some criminals illegally used 3 mobile phone software to maliciously intrude into the control network camera, and illegally used 2 computer software to scan the IP segment. The internal camera is used to crack the login password.
The offender was eventually sentenced for the crime of illegally obtaining computer information system data and illegally controlling computer information system.
"The main reason for the theft of surveillance video is that the password of the camera or the camera platform has been cracked by hackers, resulting in leakage." The technical director of an information technology company told reporters that to solve this problem, it is not to update equipment, but to increase network security equipment to allow the entire network The security mechanism is used to ensure the security, and at the same time, the entire original system is upgraded safely. "Actually, (the problem) is a weak password, which can be solved by increasing the password strength. Users need to improve their security awareness, especially the protection level of the equipment manufacturer's central computer room."
In addition, by searching for keywords, the reporter found that in recent years, many criminals have used pinhole cameras and other equipment to secretly install cameras in hotel rooms, rental houses and other places involving personal privacy, and secretly photographed privacy pictures. Network dissemination or sale for profit.
"Through technical means, the hacked cameras can be used to conduct 'yellow broadcasts' (that is, monitoring live broadcasts) on gambling platforms, and you can earn 10,000 to tens of thousands a night; you can also sell these video resources to others." A seller who made pinhole cameras told reporters that he was arrested by the police for selling pinhole cameras, but was released on bail by the procuratorate due to insufficient evidence, so he was very familiar with the situation of video black production.
According to him, some people who master illegal video resources will establish relevant resource groups on the Internet, and publish candid videos in the group for publicity and attraction, "Those who have further needs need to transfer money to the group owner through WeChat or Alipay to be able to do so. Get into a higher-level group to get video assets."
look deep into
Whether there are loopholes in the platform audit mechanism
According to the above-mentioned sellers, in order to expand the source of customers, some criminals will upload illegal videos in their hands to major website platforms, thereby attracting more people to join their resource groups.
Regarding whether the video will pass the review, it said that some will not, but there are always omissions.
It is understood that at present, major domestic short video platforms require users to abide by relevant requirements and regulations when uploading video works. other content prohibited by administrative regulations”.
However, when the reporter inquired about the relevant regulations, they found that although some platforms have made requirements for uploaded video works, they have not made detailed explanations of their review standards.
For example, although Station B refuses to accept manuscripts containing content that violates the "Administrative Measures for Internet Information Services", it does not provide detailed explanations on the video review standards.
Regarding the review process of video manuscripts on the Internet platform, an up master who produced and released videos at station B told reporters that the review process of video content is usually a machine using relevant algorithms to review the illegal content, and if there is a violation, it will be reviewed manually, "This It is the default operation method in the industry, but there are too many videos on head platforms like Station B, and even manual review is estimated to be 8 times faster.”
A staff member of station B told reporters that the video review work of this station is all manual, but there are many factors to consider, and a reporting and review mechanism has also been established at the same time, "Although we strive to be 100% correct, due to the large amount of review and There are many factors that need to be considered, and it cannot be ruled out. Therefore, we also have matching manuscript reporting channels and irregular in-site inspections. By combining these methods, a relatively complete mechanism is formed. Even if the manuscripts that have been reviewed are verified to have problems The same will be dealt with accordingly.”
However, when looking at the common problems in the "violation regulations" of Xigua Video, the reporter found that the platform is only handed over to manual review after users encounter problems uploading works and submit complaints.
According to the platform's response, the platform uses a unified review standard, and manual review will be conducted only after there is a problem appeal, but the probability of its own review being wrong is very small.
