The Firmware Security Testing Methodology (FSTM) is composed of nine stages tailored to enable security researchers, software developers, consultants, hobbyists, and Information Security professionals with conducting firmware security assessments. Stage|Description 1. Information gathering and reconnaissance|Acquire all relative technical and documentation details pertaining to the target device’s firmware 2. Obtaining firmware|Attain firmware using one or more of the proposed methods listed 3. Analyzing firmware|Examine the target firmware’s characteristics 4. Extracting the filesystem|Carve filesystem contents from the target firmware 5. Analyzing filesystem contents|Statically analyze extracted filesystem configuration files and binaries for vulnerabilities 6. Emulating firmware|Emulate firmware files and components 7. Dynamic analysis|Perform dynamic security testing against firmware and application interfaces 8. Runtime analysis|Analyze compiled binaries during device runtime 9. Binary Exploitation|Exploit identified vulnerabilities discovered in previous stages to attain root and/or code execution
