Introduction
Process injection is a technique widely used in the field of cybersecurity and software development. It involves injecting code into a running process, thereby manipulating its behavior or gaining unauthorized access. While process injection has legitimate uses in debugging, software testing, and performance optimization, it is also a favored method among malware authors for malicious activities.
In this blog post, we will provide a high-level overview of process injection, explore various WinAPI calls involved, and present a code example for process injection.
High-Level Overview of Process Injection
Process injection refers to the act of injecting code or data into a running process, with the intent to alter its behavior or exploit its functionalities. The injected code can execute within the context of the target process, enabling the attacker to evade detection mechanisms and carry out malicious activities. Process injection techniques can be broadly categorized into four types:
- DLL Injection: This technique involves injecting a dynamic-link library (DLL) into the target process. The injected DLL can contain additional functionality that the process did not originally possess.
