Is reverse engineering useful?

Because reverse engineering can be an invaluable tool for learning how to use a particular programming language or how to work on a particular type of application, beginners can use the technique to improve their skills.

How does the Haskell compiler work?

Haskell is statically typed. When you compile your program, the compiler knows which piece of code is a number, which is a string and so on. If a function you make takes two parameters and adds them together and you don’t explicitly state their type, the function will work on any two parameters that act like numbers.

Is C good for reverse engineering?

In my opinion, it’s almost mandatory, it’s the language the closest to assembly with just higher abstraction to get a better grasp at the big picture. Most of the things you’ll reverse are derived from C, and this will be an invaluable help to understand most of the usual construct patterns.

Is Haskell interpreted or compiled?

Unlike Python, Ruby, JavaScript, Lua, and other interpreted languages, Haskell is compiled ahead-of-time, directly to native machine code.

Is Haskell compiled to C?

It is all compiled [or rather, linked] together. If you write a C program, one C function can call another C function. When Haskell calls a C function, it’s pretty much like any other function calling that C function.

How do you solve the appending problem in Haskell?

There are several ways to solve this problem in Haskell. Here a solution with cons and last/init: is inefficient since appending is an O (n) operation where n is the length of the first (left) parameter of the ++ operator. So the revList function above turns out to be O (n (n-1)/2) ~ O (n^2).

How to concatenate a list of lists in Haskell?

Take the list [1, 2, 3] for example: In the first call, x will be 1, and xs will be [2, 3]. Then you create a new list, consisting of x (so 1) at the front, followed by reverseList [2, 3]. There are several ways to solve this problem in Haskell. The naive approach would be to use the concatenate function ++:

What is reverse engineering and how does it work?

Reverse engineering is a process that hackers use to figure out a program’s components and functionalities in order to find vulnerabilities in the program. You recover the original software design by analyzing the code or binary of the program, in order to hack it more effectively.

Where can I find a list of practice binaries?

A list of practice binaries can be found here: First, before we jump into using Ghidra, here are a few command-line utilities that you can use to gain information about a binary. The strings command finds the printable strings in an object, binary or file. The file command will reveal the file type of the file you are analyzing.
