MuchMany of the risks hashave already been covered in the post by Mayank Sharma. I just want to add on this by saying that wifi clients trust relationship with the access point is highly influenced or motivated by signal strength or, i.e. the proximity of thebetween client and the access point.
Such is the case that an open access point that is put near towhen your wifi powered laptop with wifi enabled and set up to automatically connect (in itsits default setting) would, when put near an open access point will always tries to attempt to connect to that close by station.
You should always be vigilant about this behavior as this happens seamless in many cases it happens without any user interaction. The best way to prevent this behavior is to configure your client to always connectedconnect only to preferred access point (inyou can do that in the settings options).
