Something few realise is that when we connect our mobile phone to a wi-fi, it keeps a record of the connection.
Thereafter if the device is not connected to a hotspot, it continues to send out requests to connect to all the previous networks to which it had linked.
These can be read and we are revealing all wi-fis we have previously joined.
In effect, your movements can be tracked and often your home network will even reveal where you live just by the name you have given it.
Don't give scammers information they might use against you in some form of con.
The ninth scam of Christmas is a combination of the last two
If you keep your mobile wi-fi turned on there are methods whereby, as your mobile sends out a request to connect to a hotspot, a scammer can then pretend to be that very wi-fi.
Your mobile is relieved to have found a connection it knows and so attempts to create a link, potentially giving away your wi-fi password.
Worse still, your mobile might think it has a secure connection and start to send other data that can be picked up by the scammer.
This and the two previous scams can all be stopped by simply turning off your wi-fi on your mobile's settings when not on a hotspot you trust.
The 10th scam of Christmas is the insecure website
Whether intentional or not, some websites still ask you for your credit card details - and much other valuable personal data - without offering a secure connection.
