TalkTalk cyber attack in numbers: How many millions has the telecoms giant lost?

TalkTalk’s website was hacked by cyber criminals on 21 October 2015.

Personal data including bank account numbers, email addresses, names, dates of birth, and phone numbers were accessed.

Two teenagers, one from Northern Ireland and another from London, were arrested by the police for investigation.

TalkTalk today announced its results reporting a 4.7% rise in revenues in the first-half to £912m, but cash profits fell 18% to £90m.

In a statement last month, the company said: “Our ongoing forensic analysis of the site confirms that the scale of the attack was much more limited than initially suspected, and we can confirm that only 4pc of TalkTalk customers have any sensitive personal data at risk.

“It was a difficult decision to notify all our customers of the risk before we could establish the real extent of any data loss. We believe we had a responsibility to warn customers ahead of having the clarity we are finally able to give today.”

Here are six key stats about the TalkTalk hack.

1. £35m – the amount the cyber attack has cost the company

2. 157,000 – the number of customers affected

3. 26.1% - the fall is TalkTalk shares

4. 21,000 – the number of unique bank account numbers and sort codes leaked

5. 28,000 – the number of credit and debit card details “obscured” and “cannot be used for financial transactions”

6. 15,000 – the number of dates of birth accessed
