According to a moderator over at PSX-Scene.com, chesh420, the real reason PSN might be down has nothing to do with a group of hackers trying to shut down PSN, or steal your credit cards, the real reason might be because of modders turning their PlayStation 3’s into dev units and then they gained full access into everything that’s on PSN. Now this is pure speculation as it if this is the true reason, but this is what he had to say over on Reddit:
Ok, I’ve seen a bunch of speculation of why people think PSN is down, and I thought I should just post what the community knows in comparison to what Sony is telling everyone. The truth is, there was a new CFW (custom firmware) released known as Rebug (http://rebug.me). It essentially turns a retail console into a dev console (not fully, but gives you a lot of the same options that usually dev’s only have access to). Anyway, this new CFW was quickly figured out to give CFW users access to the PSN network again via the dev networks. With a little manipulation of the URL’s through a proxy server you could get your hacked console back online. Not that big of a deal, right? Well, it also turns out that some people over at NGU found out that you could provide fake CC# info and the authenticity of the information was never checked as you were on Sony’s private developer PSN network (essentially a network that Sony trusted). What happened next was extreme piracy of PSN content. Sony realizing the issue here shut down the network. Now, before you go freaking out about the latest information posted about Kotaku, no ones personal information was accessible via this hack. Not to say they couldn’t get it, but no one is admitting to it being available. Anyway, that’s the real reason for the PSN downtime. Sony is now rebuilding all of it’s PSN servers to be more secure and (hopefully) make sure the CFW users cannot get online anymore.
If this happens to be the case, it really goes to show just how broken PSN truly was, and it would explain just why Sony decided to shut down their servers so fast and why they have been down for so long. Could the reason that Sony has been so quiet with what’s truly going on be because they don’t want to shed any further light onto the mod scene for the PlayStation? They already exposed the fact that the PlayStation could be hacked to just about anyone who watches any TV or read the news with all the Geohot problems they had. Once again, all this is pure speculation but it does seem more logical then anything else out there, and because of the fact that Sony isn’t really passing any real info along we truly don’t know what to believe.
