When Adobe Stopped Flash Content, It Impacted A Chinese Railroad (jalopnik.com) 139

Jalopnik shares a story for our times: Adobe's Flash, the web browser plug-in that powered so very many crappy games, confusing interfaces, and animated icons of the early web like Homestar Runner is now finally gone, after a long, slow, protracted death. For most of us, this just means that some goofy webgame you searched for out of misplaced nostalgia will no longer run. For a select few in China, though, the death of Flash meant being late to work, because the city of Dalian in northern China was running their railroad system on it.

Yes, a railroad, run on Flash, the same thing used to run "free online casinos" and knockoff Breakout games in mortgage re-fi ads...

Hell, YouTube used to run on Flash until 2015. It wasn't all stupid little web games but, that said, I can't for the life of me fathom why anyone would want to run a freaking railroad network on it, with physical, multi-ton moving railcars full of human beings on it. So, when Adobe finally killed Flash-based content from running, this Tuesday Dalian's railroad network found itself ground to a halt for 20 hours.

The railroad's technicians did get everything back up and running, but the way they did this is fascinating, too. They didn't switch the rail management system to some other, more modern codebase or software installation; instead, they installed a pirated version of Flash that was still operational. The knockoff version seems to be known as "Ghost Version." This, along with installing an older version of the Flash player to work with the knockoff Flash server setup, "solved" the problem, and the railroad was back up and running.

UPDATE: ZDNet reports that "later reports from Chinese media clarified that railway traffic never stopped in Dalian because of the Flash end-of-life": However, the reports also admitted that there's some truth in the original report and that, indeed, some internal traffic statistics system had stopped working at the rail station on Jan. 12, when Adobe blocked Flash content from working.

    I do a lot of security work and Flash has been a headache. Besides, Flash no longer works on Chrome, Mozilla, or Microsoft browsers, and HTML 5 effectively ended Flash's cause for existence. Adobe stopped supporting it with security updates in December, which means Flash Player is vulnerable to hackers trying to gain access to personal computers.

      Fun fact: HTML5 is just Flash all over again.
      Except with full GPU access, websockets, background threads that can and do persisit even if the tab is closed. (Or even the entire app, like I verified on Android.)

        You can access gamepads and MIDI instruments from inside a webpage now, that primarily is used to track your browsing habits. It's a whole application platform that goes beyond the invasiveness of Flash or Java applets (old shit, but same old shit).

      • Exactly, and it seems they're adding all sorts of dangerous web extension with the name Web(add your dangerous extension here) such as WebSockets, WebGL, WebUSB and others that I may not be aware of.

        These are basically JavaScript wrappers around a computer's "private parts" and seem to riding roughshod over all the security sandboxing JavaScript was originally designed with.

            Flash has nothing to do with Adobe Acrobat. It's a different technology to PDF.

            Having said that, your general point is completely correct.

          • Flash was more "sandboxed" than HTML 5's features. Flash applications didn't even have access to the HTML on the page they were embedded on.

            Holy shit did you miss the point of sandboxing. It's not about isolating from what is displayed on the page, it's isolating from other tabs, the OS, the hardware etc. There's a reason Flash was such an incredible lucrative target for exploits that basically never saw a time when there wasn't a critical unpatched zero day. By comparison Webkit's handling of HTML5 is fucking Fort Knox.

        That might be, but you have just one leaky UI engine instead of two: the browser and Flash. It's similar to Java applets. I don't believe they are necessarily more risk than browser-based apps that do the same things, it's just less parts to go wrong to only have an HTML-based browser. It's arguably unfair to Flash and applets, but that's the reality of the situation. Winner-take-all is common in many aspects of the modern world. However, we are putting all our eggs in the browser basket.

        An elderly neighbor often asks me to do PC support for her. She likes to play Lucky Slots flash game on facebook. I have been warning her that Flash has been discontinued, but she still wants to play the games. Other players of these games on facebook have used http://flash.puffin.com/ [puffin.com] as a sort of proxy to run the flash games. The puffin web site loads and executes the flash code, and then delivers it to your browser via HTML5. It's a little bit slower, but seems to work as a stopgap. Perhaps it can help with your client's security camera system.

Absent some costly SLAs, they are under no legal obligation to provide the service beyond the licensed period. That being said, for software that has no interaction or dependency on their infrastructure besides e.g. license verification, they certainly could have handled this better. One option would be to make an EOL license available for users that still wish to use it

By 2014, the powers-that-be decided that migrating existing clients *away* from Flash would... invalidate... the terms of the deployment contracts at customer sites.
