Having fun with the SNES
I once again abuse a videogame: this time the Super Nintendo, released in 1990. Join me in this weird project where I explore some crazy ideas I had on a rainy weekend!
Golang on the PlayStation 2 (part 3)
In this part we’ll dive into LLVM hell to solve some bugs, hopefully making things smoother to work with from now on. And hey, the source code is finally available to the public!
Golang on the PlayStation 2 (part 2)
The second part of my series on getting Golang on the PlayStation 2. Or, how I like to call it: how not to become a game developer. No PS2 were harmed during the writing of this post, but we are finally running on real hardware!
Golang on the PlayStation 2 (part 1)
The PS2 is more than capable of doing some wild things, including running Linux. I always wondered if we could just write baremetal Go code on it, so I decided to give it a try.
Bypassing anti-cheat software (part 2)
Let’s improve our hacks from part 1 and make it prettier! Oh yeah, and still not detected!
Bypassing anti-cheat software (part 1)
Let’s talk about defeating anti-cheat software with some custom hardware - and not being detected doing so!
Reverse engineering and fixing a streaming app
What happens when a major TV network decides to soft-block an older version of their own streaming app? Yep, we make it work again!
"Smartifying" my Hi-Fi system
Have you ever wondered if it would be possible to make a “dumb” “hi-fi system” smart? Not that smart, but simply connect a device and it would play whatever stream you want into you? Maybe even stream from your phone? Then this is for you.
Reverse engineering and fine-tuning Asustor NAS fans
The Asustor firmware can automatically control the fan speed, but sometimes the NAS can get pretty warm. Can we do better?
Reverse engineering Asustor's NAS firmware (part 2)
The VM booted, but it didn’t see any disks. In this part we’ll dive deeper into the firmware and patch the hell out of it.
Reverse engineering Asustor's NAS firmware (part 1)
It’s a x86-64 machine, so it should be possible… right?
Improving my NAS monitoring
I’ve decided to improve my NAS monitoring scripts a bit. You know, stuff you usually do on a Saturday.
Reverse engineering my NAS fan speed sensor (sort of)
I’ve played and tricked my NAS before, but now I want to know how it reads its sensors. Let’s go deeper!
Messing with LD_LIBRARY_PATH for fun and profit
A NAS full of CGI binaries and SSH root access. What could go wrong?
Reverse engineering Positivo's smart home app
Positivo released a few smart devices that can’t be easily integrated into Home Assistant. So I reverse engineered their app!
I got bored, so I hacked my TV
I don’t even know how to begin explaining this.

This is a story of why you should always check permissions on the backend!
Cabify and why you should not send sensitive data over public APIs
Sensitive data leakage is a serious issue. Even though some people don’t really care much, in the wrong hands such data could be used for pretty much anything, including identity theft. Let’s take a look at this issue today with one of my favorite transportation apps: Cabify.
Bank app permissions
Exactly one month ago I said I was going to write a post about my bank’s app permissions and the issues with privacy on it.

And we’re back with the ESP8266! Now it’s time to finally present the project and my results with it, both in its original form and the upgrades.
ESP8266: part II
This is the part II of my ESP8266 series.
ESP8266: part I
Ah, microcontrollers. Man, I missed playing with those. Seriously. Who here who has ever played with one doesn’t miss countless hours of programming and weird debugging? It’s always so much fun … mostly.
A console for RDP
