One of UK’s largest phone providers, TalkTalk, notified its customers that their personal details could be hacked from the company’s website. With this, almost 4 million customers stand at risk of having their names, addresses and baking details stolen.


TalkTalk is currently working with the Metropolitan Police’s cyber crime unit to investigate the breach. The hack occurred on October 21. Talk Talk said in a statement, “A criminal investigation was launched by the Metropolitan Police Cyber Crime Unit following a significant and sustained cyber-attack on our website… The investigation is ongoing, but unfortunately there is a chance that some of the following data may have been accessed.”

The website has been secured, and banks have been notified to monitor suspicious activity with customers’ accounts, Chief executive Dido Harding said. She further added that while the breach had not impacted the television, broadband, mobile and phone services, the website and “My Account” services have been suspended and expected to resume on October 23.

“We brought down all our websites [on Wednesday] lunchtime and have spent the last 24 hours investigating with the Met Police,” she said, as reported by the Telegraph. “It’s too early to know exactly what data has been attacked and what has been stolen. Potentially it could affect all of our customers, which is why we are contacting them all by email and we will also write to them as well.”

She said that all customers will be provided a year’s worth of free credit monitoring.

A case of data theft was confirmed by a Met Police spokesman, who said. “There have been no arrests and enquiries are ongoing.”

The company asked its customers that they be careful about their accounts, and report any suspicious activity immediately. “Keep an eye on your accounts over the next few months. If you see anything unusual, please contact your bank and Action Fraud as soon as possible. Action Fraud is the UK’s national fraud and internet crime reporting centre, and they can be reached on 0300 123 2040 or via”

In the past year, customers of TalkTalk have been made targets of a data breach for the third time.
