🚀 The Spacecraft Hacker's Handbook is heading to DEF CON this August. After a long journey, excited to finally see it out in the wild. @defcon.bsky.social @nostarch.bsky.social #hacking #defcon #space #infosec

Now shipping 🚀 https://nostarch.com/spacecraft-hackers-handbook

The Spacecraft Hacker’s Handbook authors Andrzej Olchawa (@andy.codes) and Milenko Starcik join Maria Varmazis on T-Minus: Space-Cyber Briefing to explore where space missions are vulnerable, in orbit and on Earth. https://thecyberwire.com/podcasts/tminus-space-cyber-briefing/726/notes

The authors of The Spacecraft Hacker’s Handbook found a command-queue bug in an older version of F′. Swipe to see where their investigation started, in a controlled lab.

Swipe for a sneak peek at the ground-control software lab in The Spacecraft Hacker’s Handbook 🪐 👽

🚀 I'm excited to announce that I'll be speaking at The Hack Summit this year about spacecraft hacking. We'll look beyond science fiction and explore the real attack surface of modern spacecraft. See you there! 🛰️ Check out the agenda: thehacksummit.com/en/

The Spacecraft Hacker’s Handbook authors Andrzej Olchawa (@andy.codes) and Milenko Starcik showed @davidbombal.bsky.social how patched web vulnerabilities in mission control software could expose files and send commands to a spacecraft simulator. Watch the interview: https://bit.ly/4dIRW2b

I trust small reproducers more than big opinions.

Every time I learn a new skill, I am less impressed by people who can do it too. At the same time, I have more respect for them because I understand the time and effort it takes to learn it.

Barnes & Noble is running a preorder sale today through Friday, September 11, and The Spacecraft Hacker's Handbook is included! Promo code: PREORDER25 www.barnesandnoble.com/w/the-spacec... #hacking #infosec #spacecraft #space #cybersecurity @nostarch.bsky.social

I had a great time sharing my spacecraft hacking experience at the Space Resources Conference at AGH University of Krakow and meeting other space and infosec professionals. #hacking #space #cybersecurity #infosec #spacecraft

A crash is not a failure. It is the program explaining its boundaries. #exploitdev #BinaryExploitation #VulnResearch #AppSec #InfoSec

I don't collect CVEs. I collect lessons from how assumptions fail. #ExploitDev #VulnResearch #CyberSecurity #AppSec

I've just finished prepping some homemade goodies. I'll be giving them away at @defcon.bsky.social later this week, so if you want one, find me here: - book signing event at @nostarch.bsky.social booth (Aug 7, 15:00-16:00) - Aerospace Village (on and off throughout the con) #infosec #defcon

I'm excited to share that my article on hacking SLE has been published in @pagedout.bsky.social. Paged Out! is one of the few publications that consistently delivers real depth. This one is going on my trophy wall: pagedout.institute/download/Pag... #hacking #infosec #space #cybersecurity

Spent the afternoon writing a ROP chain instead of a return address. 10/10 more satisfying than debugging RF noise floor issues. #hacking #exploit #infosec #rop #bof

If you have ever been curious what it actually looks like to break space systems and have not grabbed our book yet, this is a good moment to fix that. #hacking #pentesting #infosec #security #space @nostarch.bsky.social

It's been a few years since I jumped on the infosec train, and it's been a wild ride ever since. I'm grateful I made that decision and for everyone in my life who encouraged me to do so. #hacking #infosec #space #cybersecurity #offensivesecurity #nasa

Kennedy Space Center has always been high on my list of places to visit. I never imagined, however, that I'd have the opportunity not only to go there, but to give a lecture at Hack Space Con at the same time. #space #nasa #hacking #infosec #cybersecurity

It was finally time to make use of some stickers. #hacking #infosec #cybersecurity #pentesting #stickerart

It's been a while since I held a soldering iron, so it looks and feels super rusty, but there's nothing I couldn't hide with hot glue, I guess ;) #aerospacevillage #aerospace #defcon #badgelife #sdr @defcon.bsky.social

I'm excited to finally share that I'll be speaking at Hack Space Con 2026! 🚀🛰️ I'll be diving into space systems security and hacking satellites/ground segment, and I can't wait to meet more folks who live at the intersection of space and cyber. #space #infosec #cybersecurity #satellite #hacking

Here's my first cyberdeck, and I absolutely love it. #cyberdeck #hacking #clockworkpi #raspberrypi

It appears that Anthropic attempted to market their claims to a community that isn’t willing to purchase without careful consideration. youtu.be/fM7GIIylXqI by @malwaretech.com #hacking #infosec #cybersecurity #security #ai #llm #anthropic

Don't ask why, in my mind it makes perfect sense. #hacking #cybersecurity #kali #kalilinux #nethunter

I'm about to start listening to episode 136 of Darknet Diaries. Having such a backlog doesn't speak well of me. However bad it sounds, remember that I'm the one with 36 episodes waiting for me. #darknetdaries @jackrhysider.bsky.social #infosec #hacking #darknet open.spotify.com/episode/4cYJ...

Yup... way too much fun. #hacking #sdr #security #infosec #m5stack
