Probably most of us have never heard of lake, a University (Lakehead University), but recently the school take a measure to make the University reputation: for fear of wi-fi networks may cause damage to student health, within the scope of the whole school are forbidden to use the wi-fi network cell phone jammer.
In recent years, however, media reports repeatedly user account theft case caused by use public WiFi, the public has had the enormous fears for the safety of the public WiFi: whether to use public WiFi networking can lead to personal information disclosure, and even damage to property?
WiFi jamming devices – the most effective means to prevent hacking
How did your personal information leak out? Maybe you drink coffee, use free wi-fi, and then personal information is stolen. In recent years, free public wifi has become a hidden danger for citizens to divulge personal information and affect network security. Therefore, wifi management in public places has been brought into focus.
Hackers set a camouflage wifi, a parasite highlights of the signal is very strong, can suppress cover normal wifi signal, in the users to set up a mobile phone and network dialogue between listening level, and the operation of the first to pass your disguise wifi, then the wifi network, your personal information is in a state of no privacy. This means that everything you do on your phone can be seen.
GPS signal jammer technology can also be used to manage drones. Professor Todd Humphreys and his team have taken control of an unmanned drone through a GPS spoofing technique at Austin. They used tiny helicopters to disrupt the GPS systems on unmanned aircraft, and then to provide coordinates for drones to move towards their given targets.
It’s not the first time a drone’s vulnerability has been exposed, it’s easy to buy a GPS jammer on the Internet, and then force a drone to crash or other operations. And this signal interference is effective for all unmanned aircraft.
