Aashna Shroff, Personal Finance expert at money.co.uk, comments:

"If you booked a flight or a holiday with British Airways between June and September 2018, your personal information, including your credit or debit card details, may have been compromised. This hack is said to have affected approximately half a million customers and, just because it happened a year ago, doesn't mean that the danger for consumers is over.

"I can't stress enough how important it is to change your passwords if you've been affected by the breach. It is also vital that you remain vigilant and watch your accounts for unusual activity because the fraudsters might sit on your information for a while before acting on it.

"Unfortunately, it seems that these kinds of hacks are becoming increasingly frequent. Fraudsters consistently seem to be a step ahead, so the onus really needs to be on businesses and financial institutions to ensure that they have the systems in place to inform consumers quickly so that they can take the necessary steps to protect their accounts.

"I think we need some radical new thinking when it comes to cyber security, because we have to find a way to prevent these breaches, not just fine companies after the fact."

Advice on changing your password

  • Hackers usually try to steal your email address and password, because people often use the same combination for several accounts.

  • Change your passwords to something that is ten to twenty characters long, and that includes upper and lower case letters, numbers and symbols. This reduces your chances of being hacked.

  • Your password should be memorable, but unique, and you should avoid using anything that can be easily linked to you - such as birthdays, addresses, or names.

  • You should also avoid using the same password for more than one account, and set new passwords for every online account you use to stay safe.
