What is firmware reverse engineering?

—Firmware reverse engineering involves analyzing the code and structure of firmware to uncover vulnerabilities or modify its behavior.

Can outdated devices be a security risk?

—Yes, outdated devices often have deprecated technology and may contain vulnerabilities that can be exploited by attackers.

What is BusyBox?

—BusyBox is a software suite commonly used in embedded systems, providing several Unix utilities in a single executable.

What is Binwalk?

—Binwalk is a tool used for analyzing and extracting files from firmware images, allowing for deeper inspection and vulnerability detection.

What is Bugproof?

—Bugproof is a platform that automates IoT security analysis, helps identify vulnerabilities, and provides actionable results.
