Ph0wn CTF 2026 "Flag Ship" will be on March 13-14, 2026

Ph0wn (pronouced like *phone*) is dedicated to smart devices. Our CTF and Workshops are related to hacking smart devices, with low-level software challenges. Our goal is to have participants interact with equipment (e.g. download firmware, connect to serial port, communication with Bluetooth...) and use typical platforms for embedded devices (ARM, Micropython, MQTT, ESP32...).

Some of our best examples:

  • Ph0wn 2017: make a Parrot drone take off without the app.

Each year, we also strive to create Android, retro-gaming, hardware, OSINT and programming challenges.
