550°
2d ago - Following up on his previous update, today Sony PlayStation 4 hacker SKFU shared an update on PS4 hacking discussing the state of things Part II featuring Environment Analysis and more below.

To quote: Sadly there's no blueprint of the PS4's filesystem as far as I know, so how would we know where we want to go?

We need to collect as many information about the filesystem and it's environment as possible to even be able to determine our possible research targets and vulnerabilities.

For any PlayStation platform there are 3 good and legit ways to go for:

Way 1: Open Source Software & Open Documentation

Any Open Source Software used on the PlayStation4 is listed at [Register or Login to view links].
A quick look through them reveals that many licenses force SONY to distribute copies of the used software which for the PS4 are:

4d ago - Following up on his previous update and recent PS4 game dumps, today Sony PlayStation 4 hacker SKFU shared an update on PS4 hacking discussing the state of things Part I featuring TitleID's and more below.

To quote: Yeah I'm still here! A lot of information was collected, analyzed and misused in the past months. I want to share an overview with you and I'll start with "Part I: TitleID's".

This post is not entirely about the PS4, it will include some information about the PSV as well.

Why are we interested in TitleID's?

Both the PS4 and the PSV use the known system of TitleID's to identify games and apps. Most of them are visible to you via either the Livearea on PSV or the menu of the PS4.

Some of them, on the other hand are only used as references for internal modules or similar and are therefore hidden. The most interesting ones are those which are linked with applications you shall not see and are just implemented for tests, were forgotten or exist for other unknown reasons. Do we want to find and start them? Yes,...

40w ago - Below is a guide from wololo on SKFU Pr0xy covering how to use a proxy server with your PS4 to sniff PSN traffic for those interested.

To quote: How To Use a Proxy Server with Your PS4 to Sniff PSN Traffic SKFU Pr0xy

The following guide covers the very basics of how to install and run a proxy server on your local computer to use with your PS4. This allows you to study how the PS4 communicates with Sony’s servers, for various reasons.

A proxy lets you block some of the traffic (which has been useful in the past to let users access Netflix on their PS3 even when they didn’t have PSN access), or replace some of the traffic with connections to your own server (useful for being able to connect to the PSN on a lower firmware), or simply because you’d like to know what type of information your console sends to Sony’s servers.

Charles proxy is probably the most popular proxy around here, but it is commercial software. Thankfully, scene dev SKFU has been creating and updating his own proxy server for windows, and this is the tool I will be showing today.

There’s nothing really complex with installing...

To quote: Recently I have read Wololo's article "Best PSP/Vita Homebrew for November 2013" and noticed that my quite old "SKFU's VITA Pr0xy" is still being used by many people.

Sadly I kinda' missed to release an updated version of my proxy software anytime. Thanks to the great feedback for my old proxy, here comes the very new one: "SKFU's Pr0xy".

I did remove the "VITA" from it's name since it changed a lot after the release of my old proxy server software, I don't want people to think it is a limited to PSV piece of software. It definitely is not!

But what it is and what it got:

  • The most user-friendly Windows Pr0xy
  • Keyword filter
  • Filter plugin support (users can create and share plugins)
  • Rules by traffic direction
  • Import & Export of rules
  • Blacklist
