CCTV systems are in their prime today, and are used all over the world. These systems however can lead to a false sense of security. Most of them use proprietary software, which has not been adequately tested for security vulnerabilities. I will demonstrate this by reverse engineering the firmware, and will use that information to gain root access to the security system remotely. (This will be a demo with an Identivision DVR, and will cover the process all the way from first analizing the security equipment, to reverse engineering the firmware, using the information found to gain remote access to the system. Then I will show some things that can be done, once root access is gained.) I will also explain some of the most common security mistakes that manufacturers and users make with these security systems. I hope to give a general awareness about using their use, and the risks involved.
