TalkTalk said: "We would like to reassure you that we take any threat to the security of our customers’ data very seriously. We constantly review and update our systems to make sure they are as secure as possible and we’re taking all the necessary steps to understand this incident and to protect as best we can against similar attacks in future.

What can those who have been affected do?
- Contact your bank/credit card company, so that they can monitor for suspicious activity on your account.
- Change your password for your online accounts. Use three words which mean something to you but are random to others - this creates a password that is strong and more memorable. You should change passwords often and never use the same one twice.
- Monitor your account for any suspicious or unexpected activity.
- Beware of targeted phishing emails. If you receive unsolicited emails never reply with your full password, login details or account details. Don’t click on any links as you could end up downloading a virus.
- Be wary of anyone calling asking for personal information, bank details or passwords. If in doubt, just hang up. In the past TalkTalk customers have complained about receiving scam calls from fraudsters pretending to be TalkTalk claiming that they want to warn users about malware infections on their computer.
- Watch out for signs of identity crime. Visit Experian, Equifax or Noddle to check your credit rating to make sure no one has applied for credit in your name.

TalkTalk have also said they will NEVER:
- Ask for your bank details to process a refund. If you are ever due a refund from them, they would only be able to process this if your bank details are already registered on their systems.
- Call you and ask you to download software onto your computer, unless you have previously contacted TalkTalk, discussed and agreed a call back for this to take place.
- Send you emails asking you to provide your full password. they will only ever ask for two digits from it to protect your security.
