I like to code, hack and learn.
GitHub vs Codeberg. Any thoughts? 🤔

I feel like there's a special timezone "Central Hacker Time" that's always four hours skewed from wherever you are, or is it just me?

JarPlant-all-the-things (the Maven malware thing) is now a lot faster and has some tricks to determine in what context an implant is executed. Also updated the readme.

Sometimes I ask myself why I'm doing this.

I have this hate-love relationship with Java.

I'm actually kind of sick of Java, but knowing it well keeps generating biz, so I keep getting pulled back in.

Perhaps this explains my recent proclivity towards breaking all things Java! There's plenty of fuel for that fire, haha!

Me and @kugg.bsky.social spoke at @disobeyfi.bsky.social about playing hide-and-seek in Java land! We compare traditional Java exploitation with emerging software supply-chain attacks.

If you deal with Java and/or build servers, then this if for you!

This is the difference between single-threaded and multi-threaded #programming: 🌈

Haven't really logged in to Bluesky since the invitation. Looks like things are shaping up! I'll try to be here more. 🙂

I'd like to give some love to Ektoplazm!

It's a netlabel focusing on free (Creative Commons) music. Mostly psytrance but also some techno, glitch, downtempo, etc.

Found them way back in the day and it's so good to see them still around!

It's been all "eat, sleep, code, repeat" the last week and I love it!

Also: Listening to Cybernetika (music artist) like it's 2014 all over again. <3

Damn, I've missed programming! It feels so good to get really deep down and lost into some weird coding project. Who knows, it may even turn into something useful one day. Until then, I'll just enjoy the craft. 😌

I got really nerd-sniped by this one and I love it! 😆

It's a terminal escape room (and this time :q! is not the answer).

Of all the security training courses out there, DroneSec is probably the wildest I've heard about so far. Yes, they teach defensive and offensive operations involving those flying toys with cameras (or other payloads..)! 🤯

We live in interesting times.

WHOOP! First freelancing gig is done. The client is happy, I'm happy, my bank account is happy, everybody is happy! Mission accomplished.

I keep hearing that there's a void in the InfoSec community because of the uncertainty around Twitter/X. I wonder where this will take us. BlueSky? Mastodon? Or is the party over at Telegram and Discord these days?

P.S. I've been off of social media for a long time.
