a method of injecting malicious code into an application

What Is DLL Injection
Or Malicious Injection?

Threat actors use DLL injection (DLL Hijacking, Malicious Injection) to disrupt VDI operations or to bypass security controls such as disabling screen capture blocking or disrupting the means to block screen capture.

Risks Posed By DLL Injection Or Malicious Injection

Malicious injection is a mechanism that malware or malicious users can use to modify how an application functions on the computer; from an unmanaged device this is quite a powerful simple technique.

Examples of how DLL Injection or Malicious Injection can be used:


Malware can inject into legitimate processes, the purpose of this can be to evade detection by typical AV and EDR products.

Function Hooking

Malware can ‘inject’ into application to disrupt how applications work. for example, capturing user inputs such as the keys typed on the keyboard or spoken words into the microphone or preventing screen capture controls from being enabled.

Process Control

Through DLL injection, malware can manipulate applications to switch off features such as screen capture blocking.
