🔌 Want to teach kids electronics basics without buying hardware first? Check out this 3D hardware simulator right in your browser: community.penthertz.com/t/3d-hardwar... Drop components on a protoboard, write Arduino code, and watch LEDs blink. No soldering iron needed 😄 Parts are still limited

3D hardware simulation tool on you browser (with leds only for now)

People are a little afraid Arduino would be a dead end project since it was purchased by Qualcomm it seems (your code belongs to them, no reverse engineering allowed, data collection, etc.). So basica...

Something new in our community and that deserves more attention: Breakdown of BLERP, the BLE re-pairing attacks by Daniele Antonioli & Sacchetti (NDSS 2026). TL;DR: the BLE standard doesn't authenticate re-pairing. Paper + PoC indexed there: community.penthertz.com/t/blerp-ble-...

BLERP: BLE Re-Pairing Attacks and Defenses

Introduction Last week Daniele Antonioli posted an interesting paper and tooling (two nRF52840 boards, custom NimBLE btshell + Scapy-based Python Host for the double-channel MitM), he did with Tommaso...

POV: you demo a vulnerability on stage in 2019, release a full exploitation tool (V2GInjector), present it at conferences and then get silent for some years... ...and in 2025 it finally gets a CVE because someone else reported it to CISA 💀 At least they credited us. Thanks CISA 🤝 #CVE-2025-12357
