Maximise your Avios, air miles and hotel points

British Airways admits massive data breach including theft of credit card numbers

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

Friday 1pm update:  Various reports in our comments and elsewhere suggest that – despite BA statements – people who have booked via telephone and with BA Holidays are receiving emails saying their details are compromised.  There are also other people like myself who made redemption bookings who have not received any email.  It is probably best to assume that any transaction you’ve made which led to a BA credit card charge is likely to be at risk

Friday 12.30pm update:  IAG’s share price is down 3.6% so far today as investors worry about compensation payments and the impact on future bookings.  The overall market is only down 1.0%.

Friday 11.30am update:  It is worth noting that ba.com now says “The personal and financial details of customers making or changing bookings on ba.com and the airline’s mobile app were compromised.”  This means that you might be affected even if you did not purchase a ticket during this period.

The official ba.com page with more information is here.

Friday 10am update:  I get two paragraphs in the Daily Telegraph today, both website and newspaper – see here.  The Alex Cruz interview on Radio 4 this morning confirms that the following data has been stolen:

  • email address
  • postal address
  • credit card number
  • expiration data
  • CVV

Your frequent flyer and passport data has not been impacted as that is not transmitted during the payment process.

On the upside, there is no sign of the vest yet:

I just realised that I have not received the BA email, even though I made a redemption booking on 3rd September.  Whilst this was an Avios booking, I paid taxes on a credit card and the payment process is the same as for a cash booking.

Friday 9.30am update:  BA appears to be in breach of ICO guidelines in its email to affected customers.  To quote from the ICO website:

“You need to describe, in clear and plain language, the nature of the personal data breach and, at least:

  • the name and contact details of your data protection officer (if your organisation has one) or other contact point where more information can be obtained;
  • a description of the likely consequences of the personal data breach; and
  • a description of the measures taken, or proposed to be taken, to deal with the personal data breach and including, where appropriate, of the measures taken to mitigate any possible adverse effects.”

Friday 9am update:  This breach is ONLY related to transactions made online at ba.com, not avios.com or BA Holidays it seems. This implies that BA may not have been encrypting payment details when they were sent to their payment processor and someone was picking them up on the way. You are at NO risk if you have a credit card stored at ba.com but did not make a purchase during this 2-week period.

Friday 8am update: It now appears that 380,000 transactions have been compromised.  You should have received an email overnight if you are included. There are no reports so far of card fraud linked to the breach and credit card companies are NOT replacing cards automatically. If you are nervous, you can report your Amex card as ‘lost’ via the website and it will be replaced.

The following press release just turned up from British Airways five minutes ago, for your information:

BRITISH AIRWAYS: THEFT OF CUSTOMER DATA

September 06, 2018

“British Airways is investigating, as a matter of urgency, the theft of customer data from its website, ba.com and the airline’s mobile app. The stolen data did not include travel or passport details.

From 22:58 BST August 21 2018 until 21:45 BST September 5 2018 inclusive, the personal and financial details of customers making bookings on ba.com and the airline’s app were compromised.

The breach has been resolved and our website is working normally.

British Airways is communicating with affected customers and we advise any customers who believe they may have been affected by this incident to contact their banks or credit card providers and follow their recommended advice.

We have notified the police and relevant authorities.

Alex Cruz, British Airways’ Chairman and Chief Executive said “We are deeply sorry for the disruption that this criminal activity has caused. We take the protection of our customers’ data very seriously.”

British Airways will provide further updates when appropriate.”

Coming just a week after the high profile launch of the September sale – bookings for which have been caught up in this – the timing could not be worse.

I feel a bit sorry for British Airways at the moment.  They have spent the last year reversing the cut-backs of 2016 (the changes to Club Europe catering on the 12th are almost the final piece of the jigsaw) but there is no sign of public perception improving.  Good news, of course, makes for less interesting press coverage than bad news, which is why coming back from bad publicity is always hard.

Following on from the IT outage from last year, this theft is likely to raise more questions about the decision to move much of BA’s IT infrastructure to India.  Whatever money it saved will be peanuts compared to the costs of dealing with this breach.

And, given that I made a couple of redemptions last week, it looks like I’m going to need a new British Airways American Express card ….

  • Simon says:

    I received the “you may have been affected” email.

    Is there / Will there be another email if they know for sure you have been affected?

    At the moment, not going to do a thing. Amex is your friend if any fraudulent transactions go through.

    • luckyjim says:

      So if, in a couple of months time, the fraudsters start charging you £8/month for a plausible sounding service you are relying on Amex to spot that? They have no incentive to do so. Or you are sure you’ll spot it yourself?

      Amex is not your friend. It is a profit driven financial institution.They have done the math and concluded that it is cheaper for them to accept and monitor the risk. That is not necessarily what is best for you as an individual.

      • Simon says:

        Yes I’m very confident I can read my statements. It’s something I always do. And i have 100% faith that Amex will cancel any transactions that arent mine. I will never be out of pocket.

      • Brian W says:

        Nonsense comment. Amex have always dealt with issues like this properly.

  • Robman says:

    So, if I understand this correctly, if my flight details e.g. (when I’m not going to be home) and my postal address are known, that whoever penetrated BA payment system has the ability to rob my house while I’m away. And they know exactly when I won’t be there and when I’m coming back. If so, this is very worrying and shocking loss of data. More worrying that the loss of credit card information.

    • Rob says:

      Flight details are not known because those are not sent to the credit card company.

      • Craig says:

        So how do the flight details, passenger name and ticket number appear on an Amex statement Rob?

        • Robman says:

          You are right Craig. These details appear on the statement. Scary indeed and needs more clarification as to exactly what are the risks to the customer as a result of the breach. Credit card fraud is one thing to worry about, your homes security is even more concerning. How do we find out the truth of where we are exposed?

        • Rob says:

          I believe that goes across separately, because Visa / MC do not see that data. If they did, they would use it.

    • Simon says:

      I think this concern is over-done. What about anyone who works at Heathrow, or at a parking company, or a taxi firm’ or a postman etc. Numerous easier and cheaper ways to learn when people are out the country….

  • Jtb says:

    I’ve got the (soon to be discontinued) Lloyds Avios cards; after 30 mins on hold with them last night, they told me that they weren’t cancelling cards but I should monitor my account. Meh.

    Need Rob to do an article on best cards without fx charges…

    • wmdore says:

      How do they compare to Revolut? No transaction fee is fine but do they take a cut on the exchange rate?

      • Rob says:

        You cannot take a cut on the exchange rate. They are obliged to use the Visa / MC rate which is published on their websites.

    • Jtb says:

      Thanks Rob. Got an affiliate link I can click to apply?

    • Oh Matron! says:

      Have been a user of Tandem for some time also. Get’s my vote. And, no, they don’t take a cut of the FX rate

  • Ian says:

    It’s now being reported that it was malicious software that ‘recorded’ key strokes as they were entered into the site. Which is why they were able to get the CVV numbers.

    There was no actual lifting of data.

    • Ian says:

      By the way, that’s from Rory Cellan-Jones of the BBC.

      • BlueHorizonUK says:

        But that doesn’t make sense. Would mean that they have infected hundreds and thousands of devices and stolen all my key strokes on any site I used.

        • Ian says:

          He was saying the software was overlaying the web page where payments were made, so not recording your device but recording was was going in to BA’s, as it were.

          I’m not sure how he knows this, but he does know his stuff.

        • dodgy says:

          what sites have you been visiting sir? 😉

    • luckyjim says:

      No, that does not make sense. How would all browsers and the app be affected? More likely to be a vulnerability in the middleware that passes data to the payment processor.

      • Ian says:

        Here’s the theory:

        “It looks very much like the details were nabbed at the point of entry – someone managed to get a script on to the website.”

        https://www.bbc.co.uk/news/technology-45446529

        • luckyjim says:

          Yes, I think the journalist has slightly misinterpreted what Prof Woodward is saying. If the card data was being captured ‘as customers typed’ then everyone who visited the site would be at risk – even those who did not complete a purchase.

          Capturing the credit card data ‘in flight’ is the most likely scenario. My theory is that the payment data was stored in an insecure cache while waiting to be processed. Stupidity on BA developers part is far more likely than ground-breaking genius of the part of the hackers.

  • BlueHorizonUK says:

    BTW you don’t have to call Amex to cancel your card. You can go to card management in the site and chose lost card and get a replacement.

  • Marcw says:

    No big corporation is immune to data theft. It should always be in your risk assessment.
    I’m not affected, but was so in the past, and back the the company took month to publicise the data theft.

  • The other Kevin says:

    “Once fraudsters have your personal information, they may be able to access your bank account”
    Incredible scaremongering on the BBC website. Exactly how are fraudsters meant to get at your bank account with the limited details that have been stolen?

    • Anna says:

      I’m assuming this would only affect someone who had paid with a debit card linked to their bank account. So no HFP readers!

  • signol says:

    I made a rental car booking during the affected period (I’d assume this counts as “Holidays”) and received the email this morning saying my details have been affected. My card details were amongst the stolen data – the Amex from the Lloyds Avios account. I’d used it to book a car rental two weeks ago, and received the email from BA this morning. I phoned Lloyds who also said “wait and see”, but did give the option to cancel the card and have it reissued, which I have obviously done. I was assured that the Mastercard on the account will work as normal…
