GREM Static & Dynamic Code Analysis

Question 1

What is static code analysis?

Accepted Answer

Examining the code without executing it

Answer

Static code analysis involves examining a program's code without actually executing it. This method typically involves reviewing the source code or, in reverse engineering, the disassembled binary code. Analysts look for patterns, structures, potential vulnerabilities, and malicious functions by reading and interpreting the instructions, without observing its runtime behavior.

Question 2

What is the primary benefit of dynamic code analysis?

Accepted Answer

It provides runtime behavior insights

Answer

The primary benefit of dynamic code analysis is that it provides crucial insights into a program's runtime behavior. By executing the program in a controlled environment, analysts can observe its interactions with the operating system, network communications, file system changes, and memory usage in real-time. This allows for a practical understanding of how the program functions and what actions it performs when active.

Question 3

Which tool is typically used for static analysis?

Accepted Answer

IDA Pro

Answer

IDA Pro is a leading tool typically used for static analysis in reverse engineering. It excels at disassembling binary code into assembly language and can often decompile it into a higher-level representation. This allows analysts to examine the program's structure, identify functions, analyze control flow, and understand its logic without needing to execute the code.

Question 4

Which scenario is best suited for dynamic analysis?

Accepted Answer

When analyzing runtime behavior

Answer

Dynamic analysis is best suited for scenarios where understanding a program's runtime behavior is critical. This includes observing how malware interacts with the operating system, makes network connections, modifies files, or attempts to evade detection. By executing the code, analysts can see the actual effects and interactions that static analysis alone might not reveal.

Question 5

Why might analysts use both static and dynamic analysis?

Accepted Answer

To understand both code logic and runtime behavior

Answer

Analysts use both static and dynamic analysis to gain a comprehensive understanding of a program, especially malware. Static analysis reveals the potential logic and structure embedded within the code, while dynamic analysis confirms and illustrates its actual behavior during execution. Combining these approaches provides a complete picture, allowing analysts to correlate observed actions with specific code segments and uncover hidden functionalities.
