By taking these steps, users and developers can help ensure the security and integrity of the Pico 300 Alpha 2 and similar devices, safeguarding against exploits and maintaining the trust and reliability that these devices provide.
The following sectors are most vulnerable:
: Users should transition away from Pico 3.0.0-alpha.2 to the latest stable release.
One repository includes a proof‑of‑concept video showing the Pico opening a calculator, followed by a demonstration of a reverse shell being established via a cloud server.
By sending a crafted packet of 600 bytes, an attacker can overwrite the return address on the stack. Because the RTOS does not implement stack cookies (e.g., StackGuard), control flow can be hijacked reliably.
