Prosessiruiskutukset

Prosessiruiskutukset, also known as process injection or code injection, is a technique used in computer programming and cybersecurity. It involves injecting code into the address space of another running process. This injected code then executes within the context of the target process, often inheriting its privileges and access rights.

The primary purpose of process injection can vary. In legitimate software development, it might be used for debugging, extending the functionality of existing applications, or enabling inter-process communication. For instance, a debugger might inject code into a program to monitor its execution or modify its behavior for analysis. Similarly, some antivirus software has historically used injection techniques to monitor other processes for malicious activity.

However, process injection is also a common technique employed by malware. Malicious actors can inject their own code into legitimate system processes or user applications to hide their presence, evade detection by security software, or gain unauthorized access and control. By running within a trusted process, the injected code can be more difficult to identify and remove.

Several methods exist for performing process injection, each with its own advantages and complexities. These can include techniques like DLL injection, thread injection, and process hollowing. The specific method chosen often depends on the operating system, the target process, and the attacker's objectives. Understanding these techniques is crucial for both software developers and cybersecurity professionals.
