The DNS thing isn't safe? Why is that?
Opendns is a good public server. Pretty popular too..
So, what can this exploit lead to in the future? I have some knowledge, but nothing like this.
Just took a brief look at the dump and basically you can ignore anything after offset 0x1000000 since that's where Linux lives.
Compared to a "regular" LV1 dump, there's different content starting at 0x800000. So if you're looking for LV2 content your best chance to find something is in between 0x800000 and 0xffffff.
Another interesting fact: this dump was taken from the same PS3 the LPT triggered dump originates from. So it could help to compare the new dump to the LPT triggered one.
In regards of using (any) "unverified" or nontrusted DNS servers - it is indeed impossible (directly) to do much via DNS server itself ... BUT - who says it will not redirect the certain specific services / downloads / etc. (apart of the much needed version bypass) via his own servers to do some sniffing, eh?
As unfortunatelly using several "local" bypass methods the connection / program was pretty unstable with getting disconencted all the time and not even being able to connect to some games online at all (e.g. Everybody's Golf: World tour / Hot Shots Golf) I'm using that proxy on 2 of 3 of mine PS3s (not working for one with fw 1.50 neither any of the proxy programs so far) and all I can suggest is to remove your creditcard details linked to your PSN account and change your passwords often and keep them long and strong. It does indeed use https communication so chance of any of your details are pretty slim but still - better be sure than sorry.
A bit of OT - anyone still uses PS3 with some of the lower FWs (2.00 or 1.50 or similar) to go online? If yes - can you please at least briefly direct me to teh right direction for mine 1.50 (UK) one? I believe it SHOULD work with proxy if the "correct" version file is supplied but after several attempts to do so and all failing I'm a bit sceptic now ... Any help will be much appreciated.
it works like this, lets say i want to goto ps4news.com. i tell my browerser ps4news.com my computer tells the dns server ps4news.com and the dns server tells my computer/modem 184.108.40.206 and then wahh laaa .. i get a web site.
THERE IS NO DATA THAT TRANSFERS through the dns server. IT WOULD BE IMPOSSIBLE TO STORE SO MUCH.
I have a computer engineering degree. so i trust i explained this as simple as possible. Even it were possible to hi-jack the data .. you'd need an IBM blade server with a bunch of cell cpu's
you gotta realize every major isp runs dns servers and lets use comcast for example, they'd have 20 million people requesting websites every 10-14 seconds.
thats 100 million in less than a minute, do you know how big a log file would be for an hour, it'd take you YEARS to decipher any infomation you might have stolen, which i may add is not possible.
This is true, unless the 'hacker' controls the DNS, like in this case. There's nothing preventing the 'hacker' to change the address of ps4news.com to 220.127.116.11, which would act as a proxy sniffing out interesting stuff and then forwarding requests to 18.104.22.168 and send it back to the client.

However naive users can be fooled by page look-alikes but these cannot been certificated properly. (also possible malicious redirection...)
