Since Monday morning I have received circa 20 calls from criminals who pretend to be a “technical department” of BT.
Of course they are no such thing.
Their purpose is to deceive those victims that they call and gain control of their victim’s pc.
It is pernicious. It is at first quite convincing. Their calls always have an incoming number identifier (also called a CLI) which is false.
So heads up - treat such calls with extreme caution - do not give anything out - do not even confirm any information such as your name if asked.
Terminate the call immediately - it’s not as if you are being rude - they are criminals determined to relieve of your personal data and your money by sounding helpful and plausible…
