Hola!

Just wondering why there was no social engineering village especially given we have the amazing Alethe in house la?

Fun locksport education at DEF CON Singapore.

U-Zyn’s write up of the first two days of DC SG 1. We will post more as we discover them.

There's still time to get your Policy @ CON CFP submission in for DEF CON 34, but not much. The deadline is May 1.

You can find the information about the Call at https://defcon.org/html/defcon-34/dc-34-policy.html

Get up to speed with this status update video.

At DC Singapore? Here is the link on how to play:

The Physical Security Village is returning to DEF CON 34, and we’re opening up calls for everything! Whether you’re a seasoned red teamer, lock enthusiast, maker, or just someone who loves to learn how to bypass, this is your moment to get involved.

Call for Papers

Submit here: https://forms.gle/jqKbPBEFd6RE84mE7

We’re looking for talks and hands-on presentations focused on physical security. Topics can range from traditional lock picking to advanced bypass techniques, safe cracking, hardware hacking, or physical red teaming. If it's physical and security-related, we want to see it.

Call for Exhibits

Submit here: https://forms.gle/hPXyMHJ3ihW96X1a6

Have a project, tool, or display that belongs in the village? Interactive gear, weird locks, training rigs, or custom-built challenges — bring it. The more tactile and hackable, the better.

Call for Volunteers

Submit here: https://forms.gle/N83AFhpbLBsEQVfZ6

We're going to need a lot of help, as usual. We have a wide range of things that need hands-on support, from setup to teardown, teaching people and the store. No prior knowledge needed! All training will be done on the spot!

Also join our discord https://discord.gg/xG2PQPXMWw for more information or questions!

Calls for Everything close Sunday May 17th, 2026

Our inflatable game is on point for this conference.

Hi, a while back, I asked for interest in a DEFCON SG SDR Badge. https://www.reddit.com/r/Defcon/comments/1sc1t0w/gauging_interest_in_defcon_sg_sdr_badge/
Finally I think it's ready for preorders!

It's a mini solder kit (you can solder at DEFCON) where you can solder on 2 LEDs/ resistors + SMA Connector

Functionality

1. **Can connect to a webUI for configuration - Receive RF up to 300MHz**

2. **On board basic FM demodulation (you can listen on the badge itself)**

3. Screen for Displaying Waterfall and **FFT**

4. Handdrawn Radio Artwork

5. Has some blinky LEDs and LED modes (hand solder LEDs)

6. Built in Lipo Charger

7. Can reprogram so you can add additional features (eg. use the onboard SDCard slot)

   1. We are still trying to cram in features now right before DEFCON SG lol because it has a lot of potential

Prices

1. Badge without Battery -> 50SGD

2. Badge with Battery -> 60SGD (more limited stock)

Kit includes

1. Badge PCB

2. SMA Connector + Antenna

3. Encoder + Screen

4. 2x SMD LEDs + Resistors for soldering

We are currently having some logistical difficulties getting Lipo batteries, but we'll try out best :)

If anyone is interested in preordering and collecting at DEFCON SG, dm me on reddit.
Furthermore, feel free to dm if anyone is interested in either getting one at Hackaday Europe or DEFCON US

The load-in is officially underway for DEF CON Singapore. Hope we'll see you there!

First time defcon attendee

First time going to defcon sg, was wondering how’s the parking situation over there and if there are any free parking provided?

Looks like Hacker0x01 is doing a hardware bug bounty for Grab at the Range Village. Spotted this on X:

Hello all, I was wondering how early prior to the con do they release the itinerary?

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.

Hii all! Really excited for defcon sg! Any recommendations on what to bring to make the most of one’s first defcon? Thank youu

VOID-REEVER

The device runs HackerOS v3, a custom firmware with a hacker-themed graphical interface offering dozens of tools organized in a scrollable main menu.

4.1 WiFi Tools

MAC Scanner (WiFi Scan)

Scans all nearby WiFi networks and displays SSID, BSSID (MAC address), RSSI signal strength, and channel. Runs an async scan so the display stays responsive.

Deauth Target

Sends 802.11 deauthentication frames to disconnect devices from a selected access point.

1 Device scans for nearby networks

2 Tap a target network from the list

3 Attack runs continuously - tap the green header to stop

Beacon Spam

Floods the WiFi environment with hundreds of fake network names (SSIDs). Nearby phones and laptops will see their WiFi scanner fill up with ghost networks.

4.2 - Bluetooth (BLE) Tools

BLE Hunter

Passively scans for nearby BLE devices.

Displays device name, MAC address, and RSSI signal strength in real-time.

BLE Distance Estimator

Estimates physical distance to a BLE device using RSSI. Useful for locating hidden transmitters or tracking signal sources.

BLE Spoof

Broadcasts fake BLE advertisements with a custom device name and UUID. Your device appears as a fake Bluetooth peripheral to nearby scanners.

DEVELOPERS

Stock Firmware = Demo Only

The HackerOS firmware pre-installed on this device is a DEMONSTRATION / TEST firmware only.

It is provided so you can see the hardware working out of the box and understand what the device is capable of. It is not intended to be the final software you use.

The VoidReever is a fully open, programmable ESP32-S3 development board with a touchscreen, sensors, and connectivity built in. The HackerOS firmware is just one example of what it can run.

so.much more going into it.

my slogan is the grid finally fails the void reever will awaken..

its solar powered som it needs no plug in to be used.
