Q111.

How does a table interpretation layout obfuscation approach hide the structure of the code?

By burying any code structures, such as logical statements or loops, inside an unintuitive structure

By encoding the code in a table format

By converting the code into a machine language

None of the above

Discuss

Answer: (a).By burying any code structures, such as logical statements or loops, inside an unintuitive structure Explanation:A table interpretation layout obfuscation approach hides the structure of the code by burying any code structures, such as logical statements or loops, inside an unintuitive structure.

Q112.

What is the role of the jump table in a table interpretation layout obfuscation approach?

To determine the specific code address that is executed

To store the sequence of operations

To advance the instruction pointer

All of the above

Discuss

Answer: (d).All of the above Explanation:The jump table in a table interpretation layout obfuscation approach determines the specific code address that is executed, stores the sequence of operations, and advances the instruction pointer.

Q113.

What is table interpretation in the context of obfuscation?

Breaking a code sequence into multiple short chunks

Using a jump table to determine which code sequence to execute

Hiding code structures such as logical statements or loops

All of the above

Discuss

Answer: (d).All of the above Explanation:Table interpretation involves breaking a code sequence into multiple short chunks, using a jump table to determine which code sequence to execute, and hiding code structures such as logical statements or loops.

Q114.

How does table interpretation obfuscation make code more difficult to read?

It hides any kind of structure within the code

It breaks the code down into unintuitive chunks

It uses a junction to decide which code sequence to jump to

All of the above

Discuss

Answer: (d).All of the above Explanation:Table interpretation obfuscation makes code more difficult to read because it hides any kind of structure within the code, breaks the code down into unintuitive chunks, and uses a junction to decide which code sequence to jump to.

Q115.

What is an enhancement that can be added to table interpretation obfuscation?

Disassembler-confusion macros

Additional lookup table

Both a and b

None of the above

Discuss

Answer: (c).Both a and b Explanation:An enhancement that can be added to table interpretation obfuscation includes both disassembler-confusion macros and an additional lookup table. These enhancements make the code significantly more unreadable to human reversers and complicate matters for a deobfuscator.

Q116.

What is the purpose of using pointer aliases in obfuscation?

To prevent static analysis of the code by deobfuscators

To make the code more readable to human reversers

To increase the performance of the obfuscated code

To confuse the compiler during compilation

Discuss

Answer: (a).To prevent static analysis of the code by deobfuscators Explanation:Pointer aliases are used to confuse automated deobfuscators and prevent static analysis of the code.

Q117.

How do pointer aliases complicate data-flow analysis?

By making it difficult to predict the state of the array

By slowing down the runtime performance of the code

By making the code unreadable to human reversers

By making it easier for the compiler to optimize the code

Discuss

Answer: (a).By making it difficult to predict the state of the array Explanation:Pointer aliases make it difficult to predict the state of the array, which complicates data-flow analysis.

Q118.

What is inlining in the context of compiler optimization?

Duplicating functions to any place in the program that calls them

Replacing every call into a function with an actual in-place copy of it

Creating internal abstractions within a function

None of the above

Discuss

Answer: (b).Replacing every call into a function with an actual in-place copy of it Explanation:Inlining is a well-known compiler optimization technique where functions are duplicated to any place in the program that calls them. Instead of having all callers call into a single copy of the function, the compiler replaces every call into the function with an actual in-place copy of it.

Q119.

How does inlining help in obfuscating transformations?

It eliminates the internal abstractions created by the software developer

It creates a new function for a certain code sequence

It bloats the size of the program significantly

None of the above

Discuss

Answer: (a).It eliminates the internal abstractions created by the software developer Explanation:In the context of obfuscating transformations, inlining is a powerful tool because it eliminates the internal abstractions created by the software developer. Reversers have no information on which parts of a certain function are actually just inlined functions that might be called from numerous places throughout the program.

Q120.

What is outlining in the context of obfuscation?

Duplicating functions to any place in the program that calls them

Replacing every call into a function with an actual in-place copy of it

Taking a certain code sequence and creating a new function that contains just that sequence

None of the above

Discuss

Answer: (c).Taking a certain code sequence and creating a new function that contains just that sequence Explanation:Outlining means that you take a certain code sequence that belongs in one function and create a new function that contains just that sequence. In other words, it is the exact opposite of inlining.
