152w ago - Today JoyStiq (linked above) speculates that based on both a NeoGAF Tip by Mr_Brit and a Digital Foundry report Sony may be planning to remotely disable JailBroken PS3 consoles essentially banning them from PSN.
To quote: "Even if you've never signed up for a PSN account, your console will communicate with Sony servers every time it boots up.
That initial load process is used to upload error logs, download updates to the "What's New" module, and a list of recently-run applications, including any unauthorized backup manager software.
Sony has yet to ban any consoles for taking advantage of the jailbreak, but the terms and conditions of the PlayStation Network make it clear that Sony has the authority to carry them out.
Thanks to the system's constant self-reporting feature, "the company even has the means to irrevocably disable your console should it so wish," rendering affected PS3 consoles unusable, online and off. But will Sony ever use such a drastic measure? And if so, how will the hacker scene retaliate?"
From NeoGAF, to quote: "On boot the system contacts the server and uploads the play list etc. this list alone is enough to get anyone that goes online banned as it shows the bootmanger etc. has been running. Here is the list and what they do, I port sniffed this a while ago before I went online with a retail unit >.> because I am not stupid hehe.
fus01.ps3.update.playstation.net > Update Server (sys updates)
mercury.dl.playstation.net > What's new ads
nsx.np.dl.playstation.net > playstation store preview
nsx-e.np.dl.playstation.net > ads
(main file exchange connections)
us.np.stun.playstation.net > on boot initiates connection
ena.net.playstation.net > SSLv3 connection after above connection
dus01.ps3.update.playstation.net > secondary update attempt (could force updates)
auth.np.ac.playstation.net > SSLv3 authentication server
service.playstation.net (has multiple IPs if only the ip address is blocked)
creepo.ww.hl.playstation.net (uploads crash reports etc.)
Almost all connections cannot just be port blocked, the port will continue to increment until it connects, you have to block the entire domains. Also a big point is that ALL computers on your network need to have these blocked not just the PS3's MAC because if you are running a proxy for example to get patches, the computer you proxy to will just allow the connections right out to the open unless all local IPs are blocked from these sites as well.
Surprising absolutely noone it looks like Sony are detecting homebrew applications meaning that everyone who went on PSN with a jailbroken console can expect to be banned eventually. This is definitely not the only way that Sony can detect jailbroken systems so we'll never truly ever know if it's going to be safe to go online. That ban may come tommorow or it may come in 6 months time but it will almost certainly eventually come."

I can confirm this cuts psn access so not much different than simply pulling the cable or setting a manual ip with no gateway.
This idea seams feasible though, i think that the best thing would be for the backup managers to simply report some random game from a list instead of showing the backup manager name lol Don't really know how that works but if this is the only way for them to know a backup manager has been used then it seems pretty easy to defeat.
Another way would be to figure out which of those connections actually send the "last played" information and block that, although that can easily be changed by Sony in an upcoming update.
Thanks for the list, i will block them using iptables on a dd-wrt router. Does blocking these prevent access to PSN or does it just block the "undesirable" crap from Sony? If it does block PSN, how it it different than simply disconnecting the PS3 from the network or having it on the LAN only (with IP and subnet but without a default gateway)?
