In computer programming, the term hooking covers a range of techniques used to alter or augment the behaviour of an operating system, of applications, or of other software components by intercepting function calls or messages or events passed between software components. Hooking can also be used by malicious code.

What is hook method?

What is a Hook Method? Hook methods provide a way to extend behavior of programs at runtime. Imagine having the ability to get notified whenever a child class inherits from some particular parent class or handling non-callable methods on objects elegantly without allowing the compiler to raise exceptions.

What is kernel hooking?

The term hooking [5] covers a range of techniques used to alter or augment the behavior of an operating system, an application or any other software components by intercepting function calls, messages and events passed between the different software component.

What is hook method in Java?

A hook is a method of interposing a piece of code in front of another piece of code, so that the first piece of code executes before the second piece of code, giving the first piece of code an opportunity to monitor and/or filter the behavior of the second piece of code.

What is malware hooking?

The ability to alter the process memory components allows an attacker to replace the entries in the IAT or modify the API function itself; this technique is referred to as hooking. By hooking an API, an attacker can control the execution path of the program and re route it to the malicious code of his choice.

Does JRE consist of API?

JRE is composed of the JVM which is the runtime interpreter for the Java language, the Class Loader, Secure Execution Implementation classes, Java APIs(core classes, SE classes) and the Java Web (Deployment) foundation which includes Java Web Start.

What does the GC () method?

System. gc() method runs the garbage collector. Calling this suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick reuse.

What do malwares use the SetWindowsHookEx function for?

The malicious program uses the SetWindowsHookEx() API to specify what type of event to monitor (such as the keyboard, mouse, and so on) and the hook procedure that should be notified when a specific type of event occurs. The hook procedure can be contained within a DLL or the current module.

What is Frida for Android?

Frida is a dynamic code instrumentation toolkit. It lets you inject your script into black-box processes(No source code needed). It free and works on Windows, macOS, GNU/Linux, iOS, Android, and QNX. Dynamic binary instrumentation helps determine a program behavior by inserting code into a binary during runtime.
