Consumers who use smart appliances without regard to security may attract hackers and thieves, making smart appliances voyeuristic.
Repeated studies have shown that devices designed for home automation have serious weaknesses. HP's survey of 10 off-the-shelf home security systems revealed that many devices have very weak password policies and are not able to guard against "man in the middle" attacks. Others did not prevent access to the device's debug interface, according to a study by code security company Veracode in April that may make the device vulnerable to hackers.
Moreover, according to a study by the security company Synack, if an attacker can access the device, then almost all devices are easily broken and become Trojan horses. In fact, as long as researchers turn on the hardware, it only takes 5 to 20 minutes to find a way to invade each device.
A sweeping robot with a camera, a monitor for monitoring children or pets at home... More and more smart home devices are entering the home, and some security holes have burst. In the hands of some unscrupulous people, they easily invade and control these smart home appliances cameras by cracking software or IP addresses. They point the camera to private places such as the bedroom or the bathroom to pry into personal privacy, and smart home appliances become voyeuristic.
What is even more frightening is that even an industry chain that steals privacy will be formed behind it. In some QQ groups, camera cracking software and camera IP addresses are publicly sold, ranging from tens of dollars to several hundred dollars. In addition to sneak peeks, there are sellers who sell private videos that have been recorded for profit as porn videos.
"Technology companies are really pushing products into the market and really competing in the Internet of Things, but there is not a single security officer in their team, so there are many small issues that have been overlooked." Colby, Synack's security research analyst Moore said, "Most companies ignore the basic principles."
Market research firm Gartner's data shows that by 2018, global corporate security spending will reach 96.3 billion US dollars, an increase of 8% over 2017. As a result of supervision, buyers’ mentality has changed, realizing emerging threats and evolving business strategies towards digitalization. By 2020, more than 60% of companies will invest in multiple data security tools, such as data loss prevention, encryption, and data-centric auditing and protection tools, which have risen from the current approximately 35%.
IDC expects global IoT spending to reach $722.5 billion in 2018, an increase of 14.6% from the $674 billion it would spend in 2017.
Although Apple Watch may be the best-known device on the Internet, many “things†you will connect to in the future will be part of your smart home appliance. Unfortunately, the enthusiasm for providing home automation functions for users has not allowed the system to achieve the required security, but it has provided network attackers with more attacks.
Brandon Creighton, Veracode's security research architect, said in a statement: "We are very excited about the realization of the Internet of Things and future developments, but this does not mean that cyber security is a victim in this process."
For example, security firm Synack tested cameras, thermostats, smoke detectors, and home automation controllers to find security holes. The company considered four scenarios that could affect consumers: hackers invaded home devices within two minutes, cell phones were stolen, eavesdropping over coffee to monitor victims over the Internet, and more advanced hackers before victims purchased Successfully modified smart home appliances.
Each device has security flaws. For example, consumers want to control their home through a smartphone, which means that losing the device may have a major impact on home safety. In addition, many products do not use encryption technology.
"I have to say I was shocked and very, very shocking," Moore said.
For those who are on the journey to home automation, there are some of the easiest steps that can make smart home appliances go as far as possible.
Lock the router
The router is the digital channel of the home, and a router with a low security factor can make it easy for network attackers to access all the smart home appliances in your network. For example, in June of this year, Ms. Hu of Hangzhou discovered that her home’s camera was not operating and she was moving. When she logs in to the mobile phone client, she finds that she has only one webcam attached to her. Two users are watching online at the same time. At the beginning of August this year, Ms. Huang of Chongqing used the camera in her home and also found that the camera mounted on the ceiling turned itself. She used a computer to check in the background and found that in addition to her own account, strangers were watching the camera.
Users should invest in routers with good security records, ensure that the default administrative password has been changed, and run the current firmware.
Prevent tampered equipment
According to the research of security company Synack, the use of smart appliances for two minutes did not give the attacker enough windows to modify the device. However, devices with USB update mechanisms are susceptible to rapid intrusion.
Home users should put the device in a place that others cannot easily access, with special emphasis on devices that have management ports.
Using cloud services
Cloud services are designed to help consumers manage home automation equipment, such as Vivint, ADT, or similar service providers, and often cost money. Without proper protection, this can lead to privacy and security issues. However, in most cases, service providers are better able to protect services than home users. If you do not use cloud services, you are responsible for checking the system's security.
Therefore, consumers can spend a certain price, choose reliable cloud service providers, make their home automation more convenient and more secure. However, users do need to choose complex passwords and should ask for two-factor authentication, which adds another layer of security to the access account.
Update device
In contrast, many developers who develop software for home automation products are new to security. David Jacoby, a security analyst at KasperskyLab, tried to invade his own home and found simple holes in his home storage product.
"Developers have an excuse to say that they are not security personnel," he said. "But we need to get vendors to fix the holes they know."
He said that due to the need for improvements in security features, application updates are a key step in ensuring that home automation devices stay safe in the simplest of attacks.
Choose a well-known brand
A company that has just been involved in smart appliances will not take the safety of their products seriously. Synack Moore said consumers should focus on companies that are committed to product and product safety.
"Of course you would rather be someone who wants to stand by and be a reputable person," he said. "At least they will stand behind their products and keep updating."
