CPENT Iot And OT Exploitation Practice Question
An assessment team is analyzing an embedded Linux firmware image for an industrial IoT gateway. They have successfully extracted the filesystem using Binwalk, but they need to statically analyze the compiled binaries for potential buffer overflows and insecure function calls. Which tool is specifically designed to perform static binary analysis and identify vulnerable functions likestrcpy within the extracted filesystem?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ghidra
Checksec or a tool like IDA Pro / Ghidra can analyze binaries, but Ghidra or Radare2 are specifically suited for deep reverse engineering and identifying insecure function imports within extracted firmware binaries. Binwalk extracts files, aircrack-ng is for Wi-Fi, and John the Ripper is for password cracking.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Aircrack-ng
Why it's wrong here
Aircrack-ng is a suite of tools for assessing Wi-Fi network security.
- ✗
Binwalk
Why it's wrong here
Binwalk is used for firmware extraction and analysis, not for deep static binary code vulnerability analysis.
- ✓
Ghidra
Why this is correct
Ghidra is a software reverse engineering framework developed by the NSA that performs static analysis to find vulnerable functions in binaries.
- ✗
John the Ripper
Why it's wrong here
John the Ripper is an offline password cracking utility.
