"Smart doorbells, smart toilets, smart refrigerators, smart cameras...With the popularization of smart devices in life, the risk of being compromised by some criminals has also increased, and the proportion of personal privacy leakage has increased." "At the salon, well-known domestic network security expert, former founder of the Green Corps, and current chief security officer of WiFi Master Key, Gong Wei said that the security problems caused by smart devices have been on the rise in recent years, and smart devices and network security issues cannot be ignored.

Camera security issues intensively broke out

A camera used for home monitoring and security may become a live broadcast tool in the eyes of others. Many media recently reported that a large number of home cameras were hacked. The Smart Camera Quality and Safety Risk Warning issued by the General Administration of Quality Supervision, Inspection and Quarantine on June 18 showed that out of the 40 batches that have been tested, 32 batches of samples have quality and safety risks, which may not only lead to the leakage of user surveillance videos, but also smart cameras. Malicious control and other hazards.

The front-end equipment is silently attacked. Behind the scenes, criminals have already formed an industrial chain through the use of cameras for illegal profit. According to Gong Wei, in the underground black production chain, many video clips are classified as "literary youth" and "single youth", and there are even "live streaming rooms" that need to be recharged to watch. Privacy is not guaranteed, and home cameras have turned into live webcasts, which is undoubtedly pouring cold water on users who love smart home products.

Smart device attacks are on the rise

According to the analysis of some security teams, in the security incidents that started last year, the proportion of attack sources coming from smart devices is on the rise. This attack source may be a camera, a doorbell, or a smart light bulb.

From PCs to tablets, to smart devices such as mobile phones, the main platforms related to network security are changing, and the problems encountered are gradually becoming more complicated, and the awareness of security precautions is changing and upgrading. "Smart devices are becoming more and more popular in daily life, and information leakage related to smart devices is showing an upward trend." Gong Wei said that devices such as smart doorbells will become puppets controlled by hackers and are subject to large-scale attacks.

With the changes in the use of platforms and use requirements, the forms of threats users have received have also changed, from malware to Trojan horses to network extortion...Secondly, the level of user information security has also increased, personal information, social relations , Residential address, wealth status, and personal credit rating are directly or indirectly recorded on smart devices.

Once smart devices are threatened, users face more severe defense challenges, and the public has an outbreak of higher levels of network security. For the security and privacy issues caused by the smart camera itself and smart device vulnerabilities. Gong Wei further explained that due to the increasing amount of personal information on smart devices, criminals use users’ private videos for extortion and blackmail, and in addition to monetizing through social platforms, they will also use methods such as crashing databases to filter and match users’ behavioral data. , The implementation of such as telecommunications fraud.

Internet is the first line of defense for security

From what level is it to prevent smart devices from being attacked? Since no computer connection is required and WiFi is used directly for networking, network security has become the first line of defense for smart device security.

"In terms of the security of smart devices, it is more secure to use professional networking tools." Gong Wei said that smart devices have security issues, and companies need to strengthen security awareness and improve product security; networks have security issues and need network services. The provider’s technological advancement. Take the WiFi master key as an example. Before connecting to public WiFi, in addition to providing three-step security precautions for the user’s mobile phone to connect to the Internet, it also has a security detection function that can inform the user to connect to this network. Whether the smart device is under attack is at risk.

Gong Wei also reminded smartphone and camera users that the use of smart devices should pay attention to the connected part. If there is a device that provides a mode to enable identification, especially the Bluetooth mode, turn on the trust of your own device, do not set it to "trust all"; need When initializing the password setting, don't neglect to set a simple password just because it is a device you use at home.
