The home camera rotates "autonomously"
Smart TV "automatically" turned on
When I woke up, I didn’t know when the light was on.
Intelligent sweeping robot works under your nose.
The "invisible guest" is watching you quietly through the sensor camera built in the robot.

Recently, a brand of intelligent sweeping robot in South Korea has been exposed to security loopholes, and hackers can remotely control it to move freely in users’ homes and spy on personal privacy. While smart home appliances bring us a more comfortable life experience, their safety has always been worrying.
The risk of smart home appliances or "spy" information being leaked.
In a set of experiments, engineers demonstrated "cracking" home cameras and smart door locks. After a series of operations on the computer, the camera was successfully hacked, and the pictures taken by it were sent back to the engineer’s computer in real time. The system shows that the video storage capacity is gradually increasing.

In another experiment, engineers use the NFC function of mobile phone (communication technology that can realize interconnection without contact), swipe the door card with a preset mobile phone, and the matching information will be stored in the mobile phone, and then swipe the phone at the door lock to open it.
According to relevant technicians, if there are security risks, different smart home appliances may become different types of "small spies":
"Eyes and ears" spy
Home cameras, smart gateways, sweeping robots with cameras, smart TVs, game consoles and other devices are easy to become "eyes and ears" spies, and it is easy to reveal the privacy pictures of users’ homes after being remotely invaded, and may also cause information such as bank card passwords and social software accounts to be leaked;
"attack class" spy
Smart rice cookers and microwave ovens with certain functions may become "attack" spies, which may cause destructive accidents such as fires after being remotely controlled;
"Coordination" spy
However, the increasingly popular security devices such as smart door locks may become "coping" spies, and "open the door" for criminals who commit crimes at home.
Post Bar, Group Selling and Cracking Smart Home Appliances Tutorial
In September this year, a survey found that in online social spaces such as Baidu Post Bar and Tencent QQ Group, there are many post bars and groups that resell the cracked account passwords of smart home devices, and even some post bars openly sell and crack tutorials about smart home devices.
In a QQ group called "Home Camera", owners and administrators post pictures taken by cracked home cameras from time to time. In order to avoid the detection of law enforcement agencies, its members use the "flash photo" function to show the user’s private picture, which must be viewed by using mobile QQ, and can not be captured during viewing, and will be automatically destroyed after viewing.
Crack, collect and sell … "Black Industry" through train
Because of the low difficulty in cracking smart home devices, high user usage rate and concentrated privacy information, it has gradually become an "industry" to "hack" smart home devices and steal personal privacy. Judging from the relevant cases that have been detected, cracking, collecting and peddling this series of illegal acts are often completed by one person. After the sales information is released through QQ group, Baidu Post Bar and other channels, buyers from all over the world will take the initiative to contact them, and the cost of time and money is extremely low.
Knock on the blackboard! Carefully choose smart home equipment.
Network security experts remind users that when purchasing smart home equipment, they should choose formal products produced by big brands and manufacturers as much as possible. For devices that can collect privacy information such as user’s pictures and sounds, such as home cameras, when users are at home, they can turn off the power supply and turn it on again after leaving home to avoid the disclosure of privacy information.
In addition, regarding how to prevent home cameras from being invaded, the police suggest:
① Don’t use the original preset and simplistic user name and password, and change them regularly;
2 The camera should not be facing the privacy areas such as bedrooms and bathrooms;
③ Always check whether the camera angle has changed;
④ Develop the good habit of killing viruses regularly.
