How many of the Wifi crackers on the streets are just LED lights?

The day before yesterday, the reader, Mr. Ma, passed through a cross - Street Bridge near Andingmen, and saw someone selling WiFi crackers. "The peddler claims that the password of the surrounding WiFi can be easily cracked if the cracker is plugged into the power supply." Mr. Ma is doubtful about it.

Mr. Ma said that at four or five p. m. The day before yesterday, he was seen on the east side of the Andingmen overpass on the north side of Andingmen. "The price is 50 yuan." Mr. Ma said that, from the look, the WiFi cracker was somewhat similar to the top plate, and many people were enclosing their stalls. Previously, there were also media reports that the WiFi cracker was sold in the China World Trade Center area, and that it would be easy to touch the net as long as he entered the account and password on the instructions. And this kind of rubbing is just on the spot, and when you get home, it's not so bright. In fact, the so-called WiFi decoder is actually a LED lamp that uses the USB interface to obtain power. When the power is connected, the LED bulbs flicker continuously, giving people an illusion of sending out signals out of the way.

In Taobao, the reporter saw that the WiFi cracker has not seen the product, but through a careful search, we can find some LED lights with USB interface. After the power supply, the light bulb glitters, it seems to be launching a signal, the price of the lamp is about 3 yuan.

According to some industry analysts, the so-called WiFi deception fraud sold by street vendors is very simple. The vendors use their portable wireless routers to set their passwords into simple numbers, and the buyers enter their accounts and passwords on the scene. Of course, they can easily connect to the wireless network.
