Process Injection
Process injection is a technique used by some computer programs to inject or insert their code into another running program process. The aim is to modify the behavior of the targeted program for a specific purpose.
This technique is commonly used by malware and viruses to hide their presence from detection, and to spread themselves across different systems. By injecting their code into another process, they can evade security measures and bypass access controls to steal information or damage systems.
There are different methods of process injection, including DLL injection, code injection, and hooking. DLL injection involves injecting a dynamic link library (DLL) into the target process, which can then be used to execute code from the injected library. Code injection, on the other hand, involves injecting raw code into the process, which is then executed by the process. Hooking involves inserting code into the running process to monitor or intercept its behavior.
However, process injection is not always malicious. Some legitimate uses of this technique include plugins for web browsers and game mods.
To protect against process injection attacks, security measures like antivirus software and firewalls can be used to detect and prevent malicious code from being injected into running processes.
