One Misplaced Line of JavaScript Caused the Ticketmaster Breach (itwire.com) 44

An anonymous reader quotes ITWire: Well-known British security researcher Kevin Beaumont says the breach of the British operations of American multinational ticket sales and distribution company Ticketmaster, that has led to the possible leak of tens of thousands of credit card details, was caused by the incorrect placement of a single line of code... Beaumont said Inbenta was providing a chat bot for website developers "by providing a single line of HTML which calls a JavaScript from Inbenta's Web server...."

He pointed out that while Inbenta had provided Ticketmaster a customised JavaScript one-liner, the ticketing company had placed this chatbot code on its payment processing website without informing Inbenta it had done so. "This means that Inbenta's webserver was placed in the middle of all Ticketmaster credit card transactions, with the ability to execute JavaScript code in customer browsers," Beaumont said. This code had been altered by some malicious person back in February and the problems began at that point, he said.

Beaumont warns businesses to be cautious with third-party JavaScript code in sensitive processes. "Check your supply chain. Because attackers are."

And he also highlights how anti-virus tools started flagging the the script months before Ticketmaster announced the breach. "I can see the Javascript file being uploaded to a variety of threat intelligence tools from April through just before the breach announcement, so clearly somebody was looking into it."

One Misplaced Line of JavaScript Caused the Ticketmaster Breach

    In recent years it has become common practice to use GitHub or other code sharing sites to pull in reams of third party dependencies for whatever flavor-of-the-month JavaScript framework that young coders want to use because it's trendy or because they saw an awesome demo at a conference somewhere. I guarantee that not one in one hundred of these kids has any clue what sort of dependencies of dependencies are being automatically pulled from the public repositories and being injected auto magically into their code running on top of one of these JavaScript frameworks and frankly many of them wouldn't care even if they did. They plan to be gone in 3 years or less and on to their next gig and whatever framework has come along since then to be the newest craze. Meanwhile the security oversights remain for years or maybe decades after they're gone, silently waiting for the exploit that must surely come. It would not surprise me at all to learn that nation state backed hacking groups are embedding advanced persistent threats into these public JavaScript frameworks or any of their thousands of dependencies. I predict that we haven't heard the last of these kinds of breaches because the JavaScript code slingers out there, who might have learned to code in a boot camp, haven't yet been taught a harsh lesson in security that they will remember in their bones. Some of them even show outright contempt for security or those who suggest it, although most of them are simply indifferent. They grew up with Facebook after all and their attitude tends towards, "Meh, privacy is dead, who cares"?.

      You get what you pay for. Business people see no difference in software quality, they only judge user-interface decisions and responsiveness. With no regulation, no one will care about reliability or source code quality, and development will continue its decline from earlier days that considered using formal verification and cared about fault-tolerance.

        That's true for developers, too. Companies only want young developers because they're cheaper and eager to be overworked. With that comes lack of experience and a tendency to jump on hip, flavor of the month frameworks because the tried and true stuff is so boring and old-fashioned.

        What do you expect? We allow corporations to disclaim all responsibility for breaches and the price they pay if there is a breach is usually insignificant compared with the actual damage that's been done.

        The end result is that there's no particular reason why they would care as it's not something that affects their paycheck. If something does go wrong, the managers get golden parachutes and the underlings get pink slips.

      Everyone likes to shit over JavaScript and its developers but frankly its blindsided elitism. The problem is endemic to package management and computing in general. As if anyone has line-by-line verified anything they've pulled in via nuget, apt-get or whatever package manager you'd care to mention. And even if you were to try, would you actually catch something really underhanded?

      All we have for any of this at the end of the day is blind trust. I think all of computing to some extent is faith-based that th

    • While I plead guilty of being a mix of old school geek and ISO Certified JS Toolkit hipster, I second the notion of security being handled way to lax in the web agency camp.

      However this is more often a problem of skill and awareness and not so much the toolkit. Security is always a tradeoff between usability and it has to be considered day in and day out. Most people don't have an opinion of this because they are rarely forced to take responsibility for mission critical code. Security and due diligence like

      I think it's more pragmatic than that. No one wants to reinvent the wheel, presumably when someone else has done it better. I think that's almost always a good thing, because the standard third party packages for performing most of these things is far safer than what the average developer would write. I think if someone's boss saw them rewriting something that was available as a standard, widely used NPM package they'd get an earful for wasting time.

    Don't give me the "it's only one line" bullshit because sites use condensed javascript files that only have one line! It's like saying someone was killed by an speeding piece of steel after being hit by a bus. Sure, it's technically correct and completely misleading.

    • It's like saying "a 30 mph piece of steel" It's focusing on one metric (speed/LOC) that while it feeds into the important result (momentum/?) while ignoring the multiplier (mass/includes).

    • The description makes it sound like this was just a one-line “src” link to a script on Inbenta’s server.

      But then, I’d argue that pulling web content from third-party sites is problematic in its own right - even though it’s an almost ubiquitous practice nowadays. Your web site is basically serving out content and instructions, which you have absolutely no control over or visibility into, to your site visitors. It’s bad enough when it’s ad network stuff... but this wa

    As far as I can tell:
    inBenta was hacked, and the problem was worse than it should have been because the Ticketmaster website pulled javascript from inBenta on their payment processing site.

  • WebAssembly will make this kind of problems even worse, because the included third-party binary blobs will be even harder to audit, easier to exploit and more difficult to flag.
