My first defcon in singapore

I'll attending defcon sg this time & would love to hear some pointers on what to get, what not to, what not to miss & What to prepare beforehand. Things like that.

I heards games/challenges start off with tough rules but become more flexible later on and you can only play once to win stuff. Is that true?

Btw this is my first time out of country and it's company sponsored🙂 how can I fully utilise this opportunity.

DEF CON SG is looking good!

We are working full speed almost everything off to the printers. Last minute registration sign ups are really solid, we expect to equal or even beat the numbers we did our first year of DEF CON China back in 2018, with total headcount expected over 2,600!

Exceeding our attendance goal has led to last minute problems, but the electronic badges are coming along well at the increased numbers. See everyone soon!

PS that is not an AI image. It’s an inflatable that was accidentally created too large. 😂

MalO SCP-1741-A SAO

I am designing a limited run of MalO SCP-1471-A Shitty Add-Ons (SAOs) that will be sold at DEFCON in August, 2026. Above is a work-in-progress render (not final artwork).

As part of the standard DEFCON experience, each attendee receives a circuit board they wear around their neck that serves both as a multi-day ticket for the con and as a platform to show off hardware/software hacks.

These MalO SAOs plug into the expansion port on the official con badge to allow the user to customize their standard DEFCON badge.

Among other things, these MalO units will have a screen and buttons to allow the user to play games, unlock puzzles, display screen savers, view messages, etc. The devices can communicate with one another over infrared. There are dozens of LEDs. The units have a USB port so users can hack them with Python. The units are roughly 3" wide (each button on the right is the size of a finger print)

I would like to request feedback/ideas on what games/puzzles to include on a device like this. For example, I have plans for several variations of TicTacToe to introduce the user to the controls, Snake, and a side scroller.

Ai Slop?

You know it saddens me to think that some people think I did this with ai. So just to throw a little proof out there here is a screenshot of my Google Drive. Nothing ai about that. I didnt develope this device nor am I taking credit. My best friend who is from Argentina did. He's currently living in Europe.. and to be honest. He made this so I could exclusively sell it here in the united states to help me. Im paraplegic after getting hit by a train October 24th 2023. Broke almost every bone on my left side. Spinal cord injury t6-11. Im so lucky to be alive..its been quite the journey having to reinvent myself. But I dont look for pity. My whole family is from Costa Rica and im in the us alone and been doing this alone. I was even homeless in a wheelchair for 7 months. Despite the horror this may sound like. Im ok.i have my head held up high and determined to prove the doctors wrong. And I already did. I can climb into my rv and walk around it a little gimp currently but I will walk again. The ssi I get isn't shit. But I dont care about money really.i love gadgets and been a tech head since my dad bought me a super Nintendo. Matter of fact, im going to do this just to put it out there for everyone interested..even if it means cutting myself out the opportunity because id want everyone to be able to enjoy such an amazing gadget. Go to SGPcard.com and if you do purchase anything just mention me as the referral please. My names Eric Flores. the voidreever isnt available but the 2 he does have on there are just as cool just not as bad ass. I cost close to 500 just for the parts in total not counting the hours its takes to asemble one unit. If you interested in one price tag is $1200 it will be made by hand and sent to you. You can even message him on the website yourself and pay him directly. Ill get my commission because like i said he does not even advertise the model im promoting. Just check the website out and see for yourself.

DefCon Group DCG518 presenting 'Making honey out of Go or how I stopped worrying and vibed' this Saturday, April 25th 2026 in Albany, NY

HoneyGo is waiting for you, ... just click it.

DEFCON Group DCG518 wants to share an invite with the community. This Saturday, April 25th 2026 we are presenting:

#Making honey out of Go or how I stopped worrying and vibed

Honeypots are one of those beautifully deceptive tools in security, that have long been a staple in offensive security and threat intelligence, quietly sitting in the dark, luring attackers in, capturing their tools, tactics, and mistakes. Honeypots provide an organization with proactive, high fidelity defense layer by creating a decoy targets that simulates real IT assets. They are used in everything from red team assessments to large scale intelligence data collection, giving us a front row seat to real world adversary behavior in the wild without waiting to become a victim.

Honeygo started as a simple experiment: what happens if you build a modern, lightweight honeypot from scratch in Go? Somewhere along the way after a few rounds sparring with Gemini 3, that experiment turned into a fully functional system. In this talk, we will walk through the journey from barebones scaffold to a working beta version of our honeypot, including design decisions, unexpected challenges, and a few things that broke in entertaining ways. Because it turns out, building a trap is easy, but building one that attackers don’t immediately outsmart is where things get interesting

Our New York Capital District group "DCG518" will have a gathering this time the Saturday, April 25th 2026 and it will be at the Guilderland Public Library.

More information about our group and future events on our site https://dc518.github.io

Everyone is welcome!

Recommendation

As a non cyber professional or soemone who works in the cyber field. I have been a fan of darknet diaries for 8 years now and I love the stories it makes me want to get into the profession.

I would like to read more about the sort of things jack talks about I especially love the stories about pen testing that I find very interesting.

Hopefully one day I will go to defcon and see it for myself.

p.s half of this probably doesn't make sense apologies.

DC Singapore Umbrella

We made a limited number of custom umbrellas for rainy Singapore. It took some time to find a place that can do all over printing. This is the long one. We also made foldable ones with a giant Skully logo on the outside.

If there is interest we will make some umbrellas for DC 34!

The NaClCON (Salt Con) speaker list is out and it's stacked. May 31–June 2, Carolina Beach NC

For those who don't know: NaClCON is a new, intentionally small (300 person cap) conference focused on hacker history and culture, not zero-days or AI hype. Beach venue, open bars, CTF, the whole deal. $495 all-in.

The speaker list is a who's-who of people who built the scene:

Speakers:

  • Lee Felsenstein — Homebrew Computer Club OG, designer of the Osborne 1 (the first mass-produced portable computer)
  • Chris Wysopal (Weld Pond) — L0pht Heavy Industries, testified before the Senate in 1998 that they could take down the internet in 30 minutes, co-founder of Veracode
  • G. Mark Hardy — 40+ years in cybersecurity, talking "A Hacker Looks at 50"
  • Richard Thieme — Author/speaker who's keynoted DEF CON 27 times, covering the human impacts of tech since the early internet days
  • Brian Harden (noid) — Helped build the LA 2600 scene, DC206, and DEF CON itself. Now farms and writes about himself in third person
  • Izaac Falken — 2600 Magazine / Off The Hook, 30 years in professional security
  • Mei Danowski — Natto Thoughts, speaking on ancient Chinese strategy and the birth of China's early hacker culture
  • Josh Corman — "I Am The Cavalry" founder, CISA COVID task force, currently working on UnDisruptable27
  • Casey John Ellis — Bugcrowd founder, co-founder of disclose.io, White House, DoD, and DHS security advisor
  • Jericho — 33+ years in the scene, speaking on life in an early 90s hacker group
  • Andrew Brandt — Threat researcher (Sophos, Symantec), demoing early hacking tools on obsolete hardware
  • Johnny Shaieb: IBM X-Force Red, speaking on the history of vulnerability databases
  • B.K. DeLong (McIntyre) — Attrition.org, the team that manually archived 15,000+ web defacements in the late 90s
  • Jamie Arlen — 30+ years, Securosis, Liquidmatrix; "an epic career of doing all the wrong things and somehow still being right"
  • Heidi and Bruce Potter — Developers of Turngate and founders of ShmoonCon
  • Dustin Heywood (EvilMog) — IBM X-Force, Team Hashcat, multi-time Hacker Jeopardy World Champion

Fireside chats include noid doing DEF CON war stories and Edison Carter on old-school phone phreaking in the 80s/90s and a grog filled night with the dread pirate Hackbeer'd.

A couple things worth knowing before you register:

The conference hotel (Courtyard by Marriott Carolina Beach Oceanfront) has a room block at $139/night (roughly 70% off the peak beach-season rates) so book through naclcon.com/hotel or use group code NACC. Block expires May 1st so don't sit on it.

P.S. If the tickets are too large a hurtle for you, DM me and I'll see what I can about talking to the right people to get you a discount code.

Gauging interest in DEFCON SG SDR badge

Hi, I'm currently working with a senior on an SDR badge for DEFCON SG (hopefully able to sell). We're trying to keep costs down as cheap as possible

Not too sure how demand would be like so gauging demand on reddit lol, price etc.

Edit 1: Aiming to receive at least FM Radio (theoretically up to 300MHz signals)
Edit 2: Aiming for a reasonable badge price comparable to other similar US DEFCON Badges (Don't want to overpromise price yet, but I think it'll be worth the cost compared to a normal SDR)

prototype?
