A malware analyst is examining a Mach-O binary from a macOS system. The analyst wants to identify the entry point and the main function. Which tool is most appropriate for this task?

Use 'otool' to display the load commands and the entry point, then use a disassembler to find the main function.

Use 'readelf' to display the ELF header and entry point.

Use 'file' command to identify the binary type and then use a hex editor to find the entry point.

Use 'dumpbin' to display the PE header and entry point.

What is the first step in analyzing a crash found during fuzzing?

Report the crash to the vendor without further analysis

Delete the crashing input to avoid further issues

Reproduce the crash with the same input to confirm it is deterministic

Immediately write an exploit for the crash

Which of the following is a typical outcome of a successful fuzzing campaign?

A crash report or hang that indicates a potential bug

The original source code of the application

A complete map of the application's network topology

A fully patched and secure application

What is the purpose of firmware emulation in IoT security testing?

To compile the firmware from source code

To run the firmware in a virtual environment to analyze its behavior and test vulnerabilities without physical hardware

To encrypt the firmware to prevent reverse engineering

To update the firmware to the latest version
