"Evil Twin" Wireless Routers: the new hacking approach

Hackers started using a new technique to get hold of private information from public wireless routers' users. It's called the "evil twin" approach and the technique is based on the following principles:

  • The hackers go to an area where there's a public wireless access point
  • In this area they deploy a new wireless access point with the exact same name and properties as the public wireless access point
  • This way the users are mislead in using the "evil twin" access point instead of the real one and all transfered data can be monitored by the hackers
  • In doing so, the users share private information, such as passwords, links and emails without even knowing
This kind of activities have already been detected in a first-class private lounge of an airline company in a USA airport and in a specialized workshop for luxury cars, which had a room where their costumers could use public Wi-Fi access while waiting for their cars to be ready.
