Some fun mini battery versions of BLE CTF I’m playing with.
@marunmagesh Lol, I totally forgot about the name switch up that year 🤣
I saw a student in my workshop today who had a custom BLE CTF chip in his DEF CON badge! So cool! I got a picture but I can’t make out the full name of the creator. Zer0vul something. Love it 😍.
I’m excited to announce that we are growing our security team at Strike. We are looking for a Senior Product Security Engineer to join our fully remote team. If you are interested or know someone who is interested, let us know! lnkd.in/gEHjghEW
ROFL 🤣... I was shopping around for some ESP32s microcontrollers and found this stock picture. "Let me put this ESP32 into your desktop computer?"
@NumbZombieMom It’s fine but is probably mature and very strong tasting right now. Once they start to flower the leaves get darker and thinker. I like it better before it flowers and tend to kill it off and regrow a few weeks to a month after it flowers.
@NumbZombieMom I wouldn’t eat the purple ones. They probably got peed on by a mutant animal or something 🧟
@NumbZombieMom The darker green the leaves get, the stronger the arugula taste gets. I try to pick what I need and let it keep growing. If the leaves get too dark green and strong, just mix it with other greens in your salads to cut the taste.
@DarthDomino Oooooo where is this? I haven’t skated there!
@danoot Wish I was in the future with you! Still putting overly excited kids to bed 🤯
@danoot @mangopdf All good… I just scheduled a Glamour Shots appointment at the mall tomorrow. I’m gonna get some sick headshots in a suit and swap that imaginary skateboard look with a briefcase #CorporateInfluencer
@g33k247 Nope… I did add pre compiled firmware and a docker build to the core repos to make it easier for people to flash them though.
Want to learn to hack all the Bluetooth Low Energy devices out there? Check out my new BLE CTF goo.gl/XioGzj which is geared to teach you all you need to get started in the world of BLE GATT hackery! Come check it out at this years BlackHat Arsenal!
@tmanning It’s a cool lib. I used to use it all the time for blog formatting.
I found this vids somewhere in 2019 and posted it. It is still one of my favorite interwebz vidz. I can set it on repeat and laugh for a solid 10 minutes. x.com/hackgnar/statu…
No idea where this video came from, but I will watch it over and over for the next few months:
@calderpwn cool, let me know. I just did some updates in the project to fix some of the bugs due to the newer gcc checks and such. I also added straight firmware bins and docker builds to the repo so peeps don't have to fiddle with setting up esp32 build envs & compiling
Why did I buy this book? Yesterday I randomly discovered that chapter 11 is pretty much all about my BLE CTF project ❤️
