Hardware Hacking PlayStation (Games) Sony Build

New PS3 Firmware Contains Backdoor 491

Vectormatic noted the rumor floating around that the most recent PS3 patch has a backdoor, and "Sony can now remotely execute code on the PS3 as soon as you connect. This can do whatever Sony wants it to do, such as verifying system files or searching for homebrew. Sony can change the code and add new detection methods without any firmware updates."

            Sony first advertised OtherOS (combined with the ability to play new games and the ability to get on PSN) and then removed this.

        Actually, no. The Xbox360 won't execute code without permission.

        The worst it currently does is check that your firmware and the game you are wanting to play are both up to date, and then if either check fails, tells you you will be signed out of Live (but still free to play the game in offline or LAN mode).

        Could I see MS doing this in in the future? Possibly. But I really don't think they consider it that big a deal. The people who have a hacked Xbox360 are already pretty much staying offline anyways so it wouldn't do them much good to insert this kind of code.

      • When the Kinetix was hacked to support the PC, Microsoft not only didn't get legal: they celebrated the achievement. MS has not made a practice of suing its customers. They do check the integrity of your system before allowing you to play online - that strikes me as completely reasonable, as part of a TOS for an online service - but they don't sue you if you hack your system, nor force your system to upgrade if you don't want to.

        I'm pretty sure that Philips was actually the driving force behind the creation of the Compact Disc. Besides, there was no Nintendo monopoly by the time Sony entered the console game... Sega had been providing ample competition, especially with the Genesis.

        I'd say ditch the consoles. Most decent console games are also available on the PC. The handful that you'll miss out on won't really matter in the long run anyway.

        The work was done by Sony and Philips engineers. I worked with one of the key engineers (well, I was in IT, so it is more accurate to say I worked alongside or perhaps near him) at Silicon Engineering. This story would be a lot cooler if I could remember who it was.

    The "article" calls this a rootkit. The summary calls it a backdoor. Neither is strictly true.

    Rootkits allow unauthorized users root level access and backdoors allow unauthorized remote users access. In this case, you're installing Sony software and this software allows Sony to autoupdate their software and remove cracks. This isn't much different from Chrome autoupdating or Firefox blacklisting certain extensions. The only real difference is that Sony might not have been all that forthcoming about the fact that this new firmware has this capability. My guess is that if you look at the EULA carefully, it does specify that they are allowed to do this.

    I would suggest that if you think they have trampled on your rights, then take them to court. Sony will just keep making their firmware more and more "evil" until a sizable number of users stands up and says "no more".

      So, in order to protect their revenue stream they must enforce a strong copy-protection system.

      Now, I wonder, if they were to sell a console for a price that they made a reasonable profit on, would it be so expensiv

  • If it IS true, then I don't see it as being legal, at all. I certainly do not recall seeing "Sony retains the right to install and execute software in the background, and obtain information about files stored on the device, and engage in general butt fuckery of our users, without user approval" or anything remotely like it in the EULA's.

    • But the ELUA does specify that Sony reserves the right to change the EULA whenever they want. Next time you read it they might even quote you ;) /end sarcasm

        The problem is that if they don't call out that they're doing this change and make it clear instead of in the fine print, it may negate their EULA as some of this is really non-enforceable from start to finish. You must, for example, give ample notice that you're changing the terms and doing it in a firmware update isn't it. (Makes the change non-enforceable...) Also, just because they can claim they can do this in the EULA doesn't mean they're legally allowed to do it. It's a sold item. It's roughly an

    I don't expect /. to require New York Times level of journalism (or even Fox News) but come on.

    • I disagree, information like this after the fact is more or less worthless. We'll see whether it turns out to be the case or not, but anybody that patches up might very well be in the position of not being able to undo it. A post like this is just a heads up to look out for something that might happen.

      Plus it's not like Sony hasn't done anything like this before.

  • Sounds like something from World of Warcraft? They download code that executes and without proper handshaking they know you've done something funny. Not quite the same as the Warden stuff but close enough and a real PITA to get around I'd expect. If this is simply a hook to allow the download\execute of code it's potentially a real bear to solve short of not using their network. :-(

  • the same as Microsoft uses to detect and ban 360's

    Um, no? M$ uses the MAC and unique console ID and does the banning entirely on their own end. There is no code executed on the 360 at all.

    If this is more than speculation, couldn't Sony be tried for the same 'hacker' bullshit they tried some kids for over the last few years, which I believe was "using a computer system without authorization" or something along those lines? If it's not legal for us, it's not legal for them.

  • The rules have always been quite simple. You can do whatever you want with your PS3 as long as you don't go onto Sony's gaming network. Microsoft does the same thing with its Xbox Live - you play by the rules or not at all. The sheer number of people whining about this when it's standard boilerplate business practice to control access to your own servers and private network(s) is amazing. When you connect, it verifies that you aren't running any malicious code or hacks/cheats. This has been a staple of

  • The "backdoor" is probably a way for PS3 to run arbitrary code (e.g. through PSN signon) to detect modified PS3s. e.g. if Sony knew that some byte range was indicative of a mod they might run a bit of code during signon to test that byte range. If a new CFW test appeared to counter that test they could run a new one instead. Basically they could run any arbitrary piece of code they liked. Fail the test in a manner indicative of a modded box and watch your PSN access go bye byes.

    I doubt the situation is an
