back to article Card-stealing code that pwned British Airways, Ticketmaster pops up on more sites via hacked JS

A Javascript library hosted by Feedify and used by e-commerce websites globally has been repeatedly infected this week to potentially siphon off countless victims' bank card details to crooks. The library code is typically embedded into retail webpages by site administrators and developers to add a means for shoppers to leave …

    It is phenomenal that we live in a world where it is perfectly normal for people to just dump some other company's code, being served from some other company's servers, right into the most sensitive bits of their own property without a second though. External code should be considered a a security vulnerability, whether or not it is being served "securely".

      other company's code, being served from some other company's servers

      Good grief! For some reason it didn't click that the idiots are actually running it off someone else's server - I'd always imagined that the 3rd party code had been downloaded, checked and installed. I thought that updates would be downloaded and checked before installation. But no...

        Get yourself uBlock or some other similar technology that displays a counter of blocked requests. This shit is rife. Even this page for commenting on this thread has at least six separate domains serving content into it, about half of those apparently for "analytics".

        But they're blocked, natch.

        1. Just Enough

          Too many scripts from too many places

          Running uBlock, or similar, seems like good idea. The problem is that many eCommerce sites have scripts running from so many locations, you can't tell which ones are irrelevant crap, and which are necessary for the purchase to proceed. So you end up inching through the purchase, playing guess the script, enabling each one in turn. All the time hoping that your purchase doesn't disappear with the next page reload, or end up debiting your credit card twice.

          Online retail sites need to get it through to their thick heads that I have never, ever, found the need to relay news of my online purchases to some social media account. And I am not interested in being tracked by anyone while I am on a page entering my credit card details. For any reason.

          At the point of purchase that is all I want to do; purchase. The only people involved in that exchange should be me, the website I'm on, and the relevant bank. That is all.

      It would be good if anything that took payments was JS free, and all just server side code (and from originating site only, no iframes etc.) involved (then at least the single point of failure only affects that one site)

      It would also remove the abomination of verified by visa which teaches users to accept really bad security practices.

      I wouldn't call it 'lazy' but it does need to be risk managed and not just done as a matter of course.

      Linking to very large libraries from standard sources (e.g. jsquery) can ensure that the library is cached between sites and so the browser doesn't need to download it each time store in a separate cache for each site.

      Also some third party scripts are designed to require dynamic loading from the host site for functionality based up the IP or query string etc.

      I used to be super conscious about the risks and security of third party hosted code but that didn't mean our sites didn't have any, Gower the risks were assessed. It definitely didn't mean we were lazy.

          "It's a third party you don't control. The risks are not yours to control. "

          So I guess you don't use any cloud services, hosted email, hosted web servers, third party maintained alarm systems? You don't allow any updates to software unless you have all the source code and have read and evaluated it all thoroughly? Every AV update (hourly) you check thoroughly for issues, including data transmitted and every script change? Every application you install you insist on full access to the source code and you read and work out exactly what it does to ensure there is no issue?

          Anytime there is a windows update or a new Kernel lands, you thoroughly check the source code?

          Plenty of Open Source software has had security issues or bugs that have run for many years without being spotted, btw.

          Pretty much every IT person in the world is having to trust a third party and their code on a daily basis, it's a managed risk.

          Therefore everyone who states that running third party code of any kind is too great a risk, I presume your organisations are run on a self built OS, using custom hardware chips designed and built in house with all custom software in every device including every switch and gateway?

          My comment above got a bit mangled - when I said "I used to be super conscious about the risks and security", I don't mean I stopped getting concerned, it's just I'm not in that area any more - I still would be super conscious about it if I was back in that arena. However my point is with everything as long as you understand the risks thoroughly and evaluate them then you can make a conscious decision on it. If your site uses hosted popular library and you are not processing any forms, are not a major site and are not in certain sectors then running from the official hosts over https may be considered an acceptable risk, far less of a risk than running you site over http by default in the first place (as many on these forums have advocated whenever the drive to https everywhere is mentioned). Sometimes people wish to do small amounts of e-commerce so they rely on third parties to provide the functionality on their site, or analytics to see if their site actually works reasonably or something to provide AB testing. all reasonable use cases some may feel?

          If you just slap third party code on because stack exchange has told you it is cool or so you have a super cool visitor counter then you are open for trouble.

            Sure, if you can write web page code you're obviously capable of writing everything else, obviously.

            Come on, comparing kernel updates to javascript web apps is literally childish. Go tell Torvalds that his code is a wretched hive of scum and villainy, while you're at it.

            Let's not confuse the issue, shall we ? We're talking about a humongous security hole that is without any control or oversight.

        If it's company policy then giving such orders would be an infringement.

        It would be up to the top management, preferably the board, to lay down policy; the costs of this are going to end up as sufficient to have board level visibility. It's then up to the board to ensure that the blame arrives in the right place or, failing that, the employment tribunal.

        "That will probably mean a lot of programmers get the brunt of the punishment for "following orders". "

        Then they should learn that "I was just following orders" is neither a defense nor an excuse.

        If you are a professional (and I'd hope a dev would be) then part of your responsibility is not just saying no to problematic requests, but explaining why.

        I'm not going to this because it's a bad idea, versus it's illegal, versus it's treason*. And yes, I've had to carefully explain those cases at least once to people who REALLY should have known better.

        Most of the time you can deal with these sort of situations by saying "I'm not sure, this sounds illegal/treasonous/suicidal. Can you please put this request in writing, acknowledging that you will take any and all responsibility if this blows up". Faced with having to own their decisions, often manglement will back down. Or go talk to Legal, and realise what a fuckup they avoided.

        If you want to build things, act like a fucking engineer. That involves a lot of saying "no, you have to do it the right way" to people who aren't focused on making things work as best as possible, but for a cheaply as possible.

It's not their credit cards after all, and in a week the customers will have forgotten and will be back anyway.

      I expect them to have to spend sufficient money for compensation and fines for the board to have to be concerned and even put it into annual reports. If that doesn't happen this time round I expect that when financial regulators get back from lunch they'll require them to do it.

Seems as Feedify really have an underlying issue with security of their servers, that they are unable or unwilling to fix which is allowing hackers to keep altering their code.

    This is how its going to be unfortunately

    Because of people in charge that keep spouting such phrases as "Infrastructure Free" are then in charge of all things digital. Agile gets thrown around a lot so little testing is done and when questions of security are mentioned you get branded "Difficult" and "You're being a blocker".

    Oh well. When the world and its dog insist on everything being in "the cloud" and wanting to do everything on the cheap by lifting others code officially or unofficially. And then using said code from someone else's server that you have no control over, then this is bound to happen.

    Yes, I'm not so stuck in the past that I can't see the benefits of the cloud, but I also don't want ALL our data there where I then lose control over it. I don't want my SQL databases given to a 3rd party company to manage who then refuse to allow me direct access to the said SQL database. Forcing me to use the cloud based app we've purchased from a totally different company just to be able to access fields and tables in said database.

    What am I trying to say? That digital everything isn't great but unfortunately certain directors get away with spouting bullshit to others that don't understand so believe in said bullshit. Who then pay said director thousands to make their bullshit happen. When said director knows it can never happen because "I just made it up. I never thought they'd believe me". So now has to get "something" live before legging it and doing the same at another company.

    I've lost my point again. Which is simply, management wanting everything done on the cheap and paying their staff as little as they can until they can outsource them. Then wondering why shit like this happens and just spouting "Lessons have been learned" when they haven't and it just happens over and over again.

    A more simple lesson that can be drawn

    Is that the cost of potentially having to reimburse potentially hundreds of thousands of customers whose card details may have been compromised, needs to be weighed against the utterly trivial cost of implementing a simple customer feedback form on your website yourself.

    I know that Not Invented Here syndrome is a widely understood and frowned upon phenomenon, but this case certainly illustrates where the limits of reuse need to be debated. Code hosted on third party servers looks like a very fine place to start drawing that line for commerce websites. For payment services, the liabilities are well defined, but that really should be the only third party service you allow when you're taking payments.
