Solving Google Foobar and hacking it along the way

published on
Recently I learned about the existence of what is known as Google Foobar also known as “Google secret recruiting program” or “How much bunnies can you rescue before wanting to kill someone” and being the stubborn me that I am, I decided to force my way in and try the challenges! … I didn’t expected to be able to get in but it seems I did, so I guess I’m indebted to do a writeup or something?

WireGuard and the Linux Networking Subsystem

published on
Before this article truly begins I’d like to explain what I’ve done in the last few months and what this article truly is about: As some of you may know, I worked on WireGuard as a part of the Google Summer of Code for the last 3 months, which basically is contract work for students, giving you a stipend while you work for an organization of your choice, in my case the Linux Foundation, in the open source world if selected.

How to reverse engineer a 3D Model Format: The story of MDLX

published on
Well, looks like I’m late again! I haven’t been posting as much as I wished lately because studies got in the way, but I still did some cool stuff out of this blog, being a video explaining current object recognition in AI or a KH2 Model importer (this time fixed and working!) Since I wanted to avoid posting a rant here and just fill my blog with “useless” content I’m going to write an article about the latter but I’m still doing other stuff outside of the public scope, and even planning for even bigger stuff publically (hint: Linux Foundation) !

Switch Interlude: Dumping the sysmodules

published on
Intro My finals being now a mere week away and myself just getting off the CCC I had a great idea, as always! Working a bit on the Nintendo Switch. For those unaware the 34C3 happened to host a talk about the Nintendo Switch, which led to an announcement from a modchip team of a new product ,rapidly answered by one of the speakers that was at the 34C3 giving a release date for an homebrew launcher followed by yet again another reaction from another team, showing off a coldboot exploit for the Switch.

RHme3 CTF Qualifications

published on
As it turns out, I’ve always avoided CTFs out of fear of just not being good enough to solve even the most basic problems, so when one of my friends talked me about the RHme3 CTF qualifications going on I thought, “yeah, not for me,” and just moved on. However, at 3AM the day after, when I thought while half asleep, “Oh wait, that makes easy content for my blog, jfc. Read More...

The PlayStation 2, continued from the PlayStation and launched by Sony in… wait. I’m not wikipedia am I? Just browse there if you want the usual info. So what I’m going to talk about today is how the PS2 itself was designed and how it is used by developers with both smart and un-smart tricks. Read More...

Reboot

published on
Wow I’m really bad at keeping things on time. Well here it is, the new website, with less acid irony and more sterilized content! I’ve settled on a static website generator named Hugo, like my old website but with less useless scripting and perl scripts. I also wanted to close the story on the most publicized drama I’ve been involved in in the past. You can access it here for those interested. Read More...
