#dc34 — Public Fediverse posts

I'm hacking on the #DEFCON34 #baochip badge to extend secrets management capabilities (I've largely dispensed with the #dc34 light code and am building from the ground up). Code is largely a #RustLang CLI. There's also the beginning of a #Firefox and #Chrome extension that interacts with the badge for managing passwords, TOTP, and passkeys.

Hardware-backed secrets manager

Usage: bao [OPTIONS] <COMMAND>

Commands:
  ping      Check that the device is reachable
  set       Store a password or TOTP seed
  get       Retrieve a secret to the clipboard (or --stdout)
  ls        List everything stored for each login
  history   Show when this login's password was last rotated
  rm        Delete a field, or the whole record
  passkeys  List FIDO passkeys on their own
  set-time  Push the current wall-clock time
  init      Create the encrypted store and choose its passphrase
  unlock    Open the store
  wipe      Erase every secret on the badge
  lock      Close the store
  status    Report whether the store is set up and open
  seal      Seal stdin under a named key and write the blob to stdout
  open      Open a sealed blob from stdin and write its contents to stdout
  key       Keys, and the labels they are named by
  import    Bulk-enroll `otpauth://` URIs from stdin
  help      Print this message or the help of the given subcommand(s)

Options:
      --addr <ADDR>
          Use the hosted dev fixture instead of the badge

          Or set BAO_FIXTURE_ADDR. The fixture stores secrets in PLAINTEXT and is for development
          only.

      --emu <ADDR>
          Use a badge running under the emulator instead of real hardware

          Or set BAO_EMU_ADDR. Started by `./x emu`. Unlike --addr this is a real badge image
          speaking CTAPHID; only the cable is simulated.

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

@def CON 34 is a wrap! This was an incredible second year for MHV. We are so honored and grateful for the contributions of the huge flotilla of volunteers, sponsors, creators, and partners who made this possible. THANK YOU for supporting us!

Friendly reminder for everyone who attended #DEFCON34 #DC34

Change your shoe inserts. A proper orthotic will be hard to squeeze or bend, and we'll have a hard heel. I highly recommend the tri-comfort support or the work insoles

I got ringworm in the Bellagio fountains

We just got home. Thank you all for a wonderful time! (and for all the hugs!!!) #DEFCON34 #DC34 #HugLife ☠️🐙🔎🫆🎧💾💻🫶🏻🫂

Just met Nick S. And Kara P. from @iFixit ! Turns out they're located in the city closest to us! Was great to see you all at #DC34.

Can't wait to pick up a Fixhub Soldering Toolkit. They were a breeze to use in SAO Village and HHV.

The one critical error I made for #DC34 was listening to everyone who told me not to bring a laptop. I'm a fairly analog guy when it comes to notes, but I had no idea that every other activity would be a CTF that required me to pull down files from someones local server and follow along, I'm not against it, it just didn't match my expectation. So what'd I bring instead? I have a BT Keyboard and a USBC monitor. (But iaintshootinmis I hear you cry, that's a laptop! 1/2

Best #hack of #DC34, the hotel decided that @xrichless and I definitely wouldn't have any necessity to speak to each other or see each other.

We're excited to announce our latest #LLM and #AI assisted project, #LampyMcLamperson fully #openhardware for being able to talk face to face. Talk Sunday night on the 18th floor of the Paris Hotel

Full code on github, cross platform!

The military has a booth and is actively recruiting at #DC34 is this what we've become? #Defcon

Day 2 of #DC34 and we are OPEN!
Come by and hack hardware and solder with us!

Silent disco at DEF CON scale... spoiler: it doesn't work, sounds worse than the FM audio in your car. Lots of weird spikes that hurt in your ears, every few seconds, along with hiccups where it goes silent for a full sentence. #dc34

And we're off! The #DC34 HHV CTF starts now!
Come by HHV and jump in - our friends will be glad you did... #furbtar

Putting the final touches on HHV/SSV for #dc34.
Come hang out, learn some new skills and hack on some hardware with us!

🚨🏴‍☠️ We are REALLY excited about this one! MHV has partnered with National Motor Freight Traffic Association, Inc. and Hirschbach to bring a CLASS 8 SEMI TRUCK to DEF CON 34!

You might ask - why a truck at MHV? Well, of the ~90% of goods which arrive by container ship, roughly ~60% of those are loaded on and delivered by heavy trucks.

We can't wait for you to hack it! See you all next week!
