What is hook detection?

What is hook detection? Hook detection is built into the application and detects if a rogue application has intercepted a called function that resides in a system library or within the application. Through reverse engineering and code review we discovered that this method was used by application to identify hooking.

What do you mean by hooking in programming?

Hooking.

Code that handles such intercepted function calls,…

Which is an example of a hooking method?

How is hooking used in reverse engineering software?

By modifying the source of the executable or library before an application is running, through techniques of reverse engineering, you can also achieve hooking. This is typically used to intercept function calls to either monitor or replace them entirely.

How are hooks used in the Linux kernel?

Linux provides another example where hooks can be used in a similar manner to process network events within the kernel through NetFilter . When such functionality is not provided, a special form of hooking employs intercepting the library function calls made by a process.
