emba is being developed as a firmware scanner that analyses already-extracted Linux-based firmware images. It should help you to identify and focus on the interesting areas of a huge firmware image. Although emba is optimized for offline firmware images, it can test both, live systems and extracted images. Additionally, it can also analyze kernel configurations. emba is designed to assist a penetration tester. It is not designed as a standalone tool without human interaction. emba is designed to give as much information as possible about the firmware. The tester can decide on the areas to focus on and is always responsible for verifying and interpreting the results.
