We didn't really post here during the event but DEFCON CTF Quals just concluded and LiveCTF was part of it with a new concept. Check out our website livectf.com to find links to all the recap streams we did and witness the chaotic bird training action!

I'm optimistic we can create _some_ type of knowledge-based security-related community activity but traditional online jeopardy-style CTF as a competitive format is on its deathbed and this video hurts. Big love to the community that has meant the world to me the past 11 years!

"Dad, what was it like playing CTFs before AI?"

@lolzareverser @livectf Two things here. The terminal sharing thing was always for the finals, which will happen in August. This was the qualifiers which has had a different format (check previous year's streams) but we changed the format for the quals this year and will prob for the finals too
English
Really proud of this year's edition of @livectf! And it seems to actually generate some interesting problems to solve for the teams. Next stream is in 40 min. Check it out!

I'm once again looking for a friend willing to proof-read my latest article. Ideally someone with some reverse engineering and maths knowledge.

My @REverseConf talk about reverse engineering #AoE2 is now available on YouTube: youtube.com/watch?v=Dp-Ivq… check it out and hear about some reverse engineering techniques and a code pattern matching tool I released: github.com/ZetaTwo/bnil-m…

@BackEngineerLab @belabs_engineer @belabs_james Such a great presentation! One of my favourites from the conference. Keep up the great work!

Very impressive independent research into modern software obfuscation used by Anti-Cheats, conducted by @belabs_engineer and @belabs_james

10 years ago, time flies! Competing in CodeGate with @HackingForSoju and partying with @beist was always lots of fun 😃

@lauriewired It was such a good con. Nice to see you there and thanks for a great talk!

RE//Verse was genuinely one of the best technical conferences I’ve attended (and I’ve been to a lot!).
The caliber of the attendees was super high; one of the most technical audiences I’ve ever spoken to.
It was well organized, highly caring staff, not to mention the food was really good!
Giving the keynote was fun, and I really enjoyed all the other talks as well.

Check out my new article on obfuscation (and all the other cool articles) in the latest issue of PagedOut!

Pretty cool news: We made Master of Pwn in Tokyo!
Shoutout to my mates @diff_fusion & @SeTcbPrivilege for some awesome pwning!

And in the end, neither AoE 2 nor any RTS game will be at EWC 2026. 🙃
Danny Engels | VITALITY@dannyengelz
I have so many thoughts on that Trackmania at EWC announcement. A lot of implications in this one, too. But there is something very beautiful about the fact that THE ESWC game from 15 years ago, is returning to the E(S)WC. Now we know all games for 2026 and yes, no AoE II 🤣
English
Really looking forward to share my work on #AgeofEmpires with you all and to visit the conference.
RE//verse@REverseConf
Carl Svensson (@zetatwo) is bringing Age of Empires II Definitive Edition to RE//verse 2026 as a playground for tooling. This talk walks through Binary Ninja automation to decrypt and deobfuscate game code and a BNIL query system for matching obfuscated instruction patterns. If you like game reversing you will want to see this talk: shop.binary.ninja/collections/re…

@MelonMusk75 The concept: highly debatable, I'd lean "no".
This particular implementation: ROFLMAO, not even close
English
LOL. I got emailed by some site building "open source profiles" for hiring, scraping GitHub and adding some things on top. You can opt out in your profile and they'll delete your page. The catch? There's no auth at all. Anyone can go and delete me here: algora.io/profile/ZetaTwo

I'm proud of you all. My page disappeared within an hour of posting this.

@T90Official Love you Tristan but those glasses and that 'stache combo is probably the douchiest look I've seen in quite a while. :'D

My first thought was “i’d rather die than put these things on” but my nephew thought they were cool so I had to 🤣

Happy New Year! Took some pics this holiday.
Shoutout to my nephew for the shades. 🤣
