📄️ Debugging Interface
We accessed the embedded device's asynchronous serial debugging interface while it was operational and captured some messages that were being transmitted over it. Can you decode them?
📄️ Factory
Our infrastructure is under attack! The HMI interface went offline and we lost control of some critical PLCs in our ICS system. Moments after the attack started we managed to identify the target but did not have time to respond. The water storage facility's high/low sensors are corrupted thus setting the PLC into a halt state. We need to regain control and empty the water tank before it overflows. Our field operative has set a remote connection directly with the serial network of the system.
📄️ Mission Pinpossible
Our field agent cannot access the enemy base due to the password-protected internal gates, but observed that the password seemed to be partially displayed as it was typed into the security keypad. Thanks to an audacious mission, we were able to implant an embedded device into the wiring for the keypad's monitor, and intercepted some data. Your mission is to recover the password from the collected data.
📄️ Signals
Some amateur radio hackers captured a strange signal from space. A first analysis indicates similarities with signals transmitted by the ISS. Can you decode the signal and get the information?
📄️ The Needle
As a part of our SDLC process, we've got our firmware ready for security testing. Can you help us by performing a security assessment?
