The next time you can't find the car key, remember to take a look at the fridge. Recently, the Finnish police issued an announcement suggesting that the owner put the remote control car key in the refrigerator, so as to avoid potential hacking. The explanation given by the Finnish police is that when the remote control car key is placed in the refrigerator, the signal between the car and the key cannot be intercepted by a hacker.
This explanation is not entirely unreasonable. Today’s cybercrime is increasingly rampant, and hackers can intercept the signal between the car and the key without the owner’s knowledge, thus opening the door to steal the car.
In August of this year, security researchers found a bug in the VW key, which affected more than 100 million VW owners. It may make it possible for hackers to take advantage of cheap and easy-to-buy radio hardware to intercept signals from the car's key fob and use the intercepted signals to copy the code to open the car door.
The Finnish police told the reporter: “It sounds weird, but it makes sense. Similarly, the remote control car key wrapped in tin foil can have a similar effect.â€
Some security experts do not agree with the proposal of the Finnish police to place the remote control car keys in the refrigerator, arguing that this is completely unnecessary.
Sean Sullivan of F-Secure, a provider of computer and network security, said that putting it in a refrigerator for refrigeration is more likely to damage your car keys. If the owner is concerned that the signal will be intercepted by hackers and that the car is stolen, it is recommended that the owner put the car key in a Faraday pack that can block all radio signals.
Vertical long-shaft pump is a kind of Centrifugal Pump. From the perspective of centrifugal pump, it is based on the improvement of the performance of the submerged pump, making its performance much higher than that of the submerged pump, and its running stability is stronger. . Advanced and mature vertical long-shaft pump developed to meet domestic market demand. The pump can be used to transport clean water, rainwater, iron oxide water, sewage, corrosive industrial wastewater, seawater and other liquids below 55°C; after special design, it can transport liquids at 90°C. Widely used in water companies, sewage treatment plants, power plants, steel plants, mines and other industrial and mining enterprises, as well as municipal water supply and drainage, flood control and drainage projects.
