Q91.

What is the primary advantage of automatic code obfuscation?

It makes the program easier to debug

It can obfuscate the entire program and not just small parts of it

It involves a simple reorganization of the program that is transparent to the machine

It does not make the original source code any less readable

Discuss

Answer: (b).It can obfuscate the entire program and not just small parts of it Explanation:The primary advantage of automatic code obfuscation is that it can obfuscate the entire program and not just small parts of it.

Q92.

What are control flow transformations?

Transformations that increase the human readability of a program

Transformations that add new features to a program

Transformations that alter the order and flow of a program to reduce its human readability

Transformations that add comments to a program

Discuss

Answer: (c).Transformations that alter the order and flow of a program to reduce its human readability Explanation:Control flow transformations are transformations that alter the order and flow of a program in a way that reduces its human readability.

Q93.

What are computation transformations aimed at achieving?

Reducing the readability of the code

Increasing the readability of the code

Making the code more efficient

Adding new features to the code

Discuss

Answer: (a).Reducing the readability of the code Explanation:Computation transformations are aimed at reducing the readability of the code by modifying the program’s original control flow structure in ways that make for a functionally equivalent program that is far more difficult to translate back into a high-level language.

Q94.

How do aggregation transformations affect the high-level structure of a program?

They maintain the high-level abstractions created by the programmer

They destroy the high-level structure of the program by breaking the high-level abstractions created by the programmer

They add new high-level abstractions to the program

They make the program more efficient

Discuss

Answer: (b).They destroy the high-level structure of the program by breaking the high-level abstractions created by the programmer Explanation:Aggregation transformations destroy the high-level structure of the program by breaking the high-level abstractions created by the programmer while the program was being written.

Q95.

What do ordering transformations do?

They add new features to a program

They randomize (as much as possible) the order of operations in a program so that its readability is reduced

They make the program more efficient

They increase the human readability of a program

Discuss

Answer: (b).They randomize (as much as possible) the order of operations in a program so that its readability is reduced Explanation:Ordering transformations randomize (as much as possible) the order of operations in a program so that its readability is reduced.

Q96.

What are opaque predicates?

Statements whose outcome is constant and is known in advance

Logical statements that confuse reversers and automated decompilation tools

Control flow transformations that reduce the readability of the code

Concurrency-based control flow transformations

Discuss

Answer: (a).Statements whose outcome is constant and is known in advance Explanation:Opaque predicates are fundamental building blocks for control flow transformations. They create a logical statement whose outcome is constant and is known in advance.

Q97.

How can opaque predicates be used to confuse reversers and automated decompilation tools?

By creating logical statements that are obviously false

By creating logical statements that are difficult to distinguish from the actual program code

By creating global data structures that contain random values

By creating threads that generate new random values and store them in a data structure

Discuss

Answer: (b).By creating logical statements that are difficult to distinguish from the actual program code Explanation:Opaque predicates can be used to confuse reversers and automated decompilation tools by creating logical statements that are difficult to distinguish from the actual program code.

Q98.

What is the objective of creating opaque predicates?

To reduce the readability of the code

To make the code more difficult to translate back into a high-level language

To confuse an automated deobfuscator

To create a globally accessible data structure

Discuss

Answer: (c).To confuse an automated deobfuscator Explanation:The objective of creating opaque predicates is to confuse an automated deobfuscator.

Q99.

What is the difference between confusing an automated deobfuscator and confusing a human reverser?

There is no difference

Automated deobfuscators can be confused by concurrency-based opaque predicates, whereas human reversers cannot

Automated deobfuscators can easily identify fishy-looking threads, whereas human reversers cannot

Automated deobfuscators can easily identify fake control flow statements, whereas human reversers cannot

Discuss

Answer: (b).Automated deobfuscators can be confused by concurrency-based opaque predicates, whereas human reversers cannot Explanation:The difference between confusing an automated deobfuscator and confusing a human reverser is that automated deobfuscators can be confused by concurrency-based opaque predicates, whereas human reversers cannot.

Q100.

What is the main challenge for an automated deobfuscator in identifying concurrency-based opaque predicates?

Identifying the threads that contain the actual program code

Identifying the global data structure that contains the random values

Stepping into the code to predict the behavior of the program

Dealing with the concurrent access to the data structure

Discuss

Answer: (d).Dealing with the concurrent access to the data structure Explanation:The main challenge for an automated deobfuscator in identifying concurrency-based opaque predicates is dealing with the concurrent access to the data structure.
