Firstly, my congratulations to the HENkaku KOTH solvers: Mike H. and st4rk. I hope you guys enjoyed the KOTH and gained meaningful experience from the challenge. As promised, we will release the source of HENkaku. Furthermore, you've probably heard about taiHEN - the latest release from team molecule. Maybe you've read Yifan Lu's excellent blog post, explored the taiHEN website and even tested out…

I've been asked this question a lot and in most cases it would be very difficult to have a generic solution to a problem like this. Usually the difference between two firmware versions is significant enough that a plugin tied to particular version has to be manually updated by a developer in order to work on a newer firmware. Fortunately,…

Here we are at last, the release of 6.61 Infinity. It's been over 11 years since the PSP was released back in 2004 and it's somewhat impressive how long this device lasted. There is no definitive end to the representative scene, it just gets quieter and quieter. I'm not claiming this releases is the end of the PSP, but it…

A small video update here demonstrating 6.61 Infinity working on the PSPgo. Will be working on getting custom firmwares working next and just generally heading towards a release.

Some time ago I mentioned that a 6.61 (6.60 then) boot-time hack was possible. This doesn't seem that long ago to me, but it actually has been almost a year since I mentioned it. Recently I've been rolling out actual device tests after many simulations and support software through the year. Last year all I had was a proof of…

MAZIORA PLEIADES-2 is not the codename for a military operating but actually is the name of a pigment. MAZIORA pigments change colour respective to the viewing angle, one angle might be red whilst another being blue. The video below is taken from wikipedia and demonstrate the colour changing effect.

Webkit is pretty buggy, we know that. My PSVita is on 1.80 and thus, some wonder how I've been doing things with my vita. How about a history lesson? It all started in early 2012 with a bunch of people looking into webkit. After a bit of time, a really smart dude called @cmwdotme shows us string dumps and a table of…

As you have probably seen, a small PoC webkit exploit for 2.60 was released for the psvita. You can test your vita yourself by visiting the link here: http://lolhax.org/vita.htm At first the exploit only supported 2.60, which happens to be the firmware my vita is on. The exploit now supports up-to version 3.18 and code execution demo with ROPTool will be…

I’ve done a post about Return Orientated Programming (ROP) before where I described basic operation of a ROP chain. The public domain of pentest security tools involving ROP is largely orientated around intel architecture x86. Now I have my own contribution to the security world.

Once again, I’ve not posted in a while, so I’ll start off my apologising for that. Today, I’m gonna talk about the reality of computer security. When I say reality, I immediately put my hands up and say that I’m talking bullshit and really just gonna spew a lot of my opinion in regards to computer security. So, here goes…
