TalkTalk cyber-attack: customer got scam call nearly a day before

Customer's internet connection hijacked by callers who knew his account number and threatened him as he tried to hang up

Hackers were using personal details in an attempt to scam TalkTalk customers nearly 24 hours before the cyber-attack was publicly revealed.

Iain Frater, a trainee doctor from Glasgow, said he nearly fell victim to what he described as a "very convincing scam" on Wednesday morning, in which the perpetrators hijacked his internet connection and telephoned pretending to be from the broadband company.
