NLS Code Injection Through Registry Process Manipulating

Dll injection through registry modification of NLS code page ID is a technique used by malware to inject a malicious DLL into a process by modifying the NLS code page ID in the registry.

There are two ways to accomplish this technique: 1. Calling the SetThreadLocale function and setting up an export function named NlsDllCodePageTranslation, where the main …

DLL Proxying Process Manipulating

DLL proxying is a technique used by malware to evade detection and gain persistence on a system. It involves replacing a legitimate DLL with a malicious DLL that has the same exported functions and is named similarly to the legitimate DLL.

When a program attempts to load the legitimate DLL, it will instead load the malicious DLL, which acts …

Hijack Execution Flow: DLL Search Order Hijacking Defense Evasion [Mitre]

Adversaries may execute their own malicious payloads by hijacking the search order used to load DLLs. Windows systems use a common method to look for required DLLs to load into a program. Hijacking DLL loads may be for the purpose of establishing persistence as well as elevating privileges and/or evading restrictions on file execution.

There are many ways an …

Process Injection: Asynchronous Procedure Call Defense Evasion [Mitre]

Adversaries may inject malicious code into processes via the asynchronous procedure call (APC) queue in order to evade process-based defenses as well as possibly elevate privileges. APC injection is a method of executing arbitrary code in the address space of a separate live process.

APC injection is commonly performed by attaching malicious code to the APC Queue of a …

System Binary Proxy Execution: Control Panel Defense Evasion [Mitre]

Adversaries may abuse control.exe to proxy execution of malicious payloads. The Windows Control Panel process binary (control.exe) handles execution of Control Panel items, which are utilities that allow users to view and adjust computer settings.

Control Panel items are registered executable (.exe) or Control Panel (.cpl) files, the latter are actually renamed dynamic-link library (.dll) files that export a …

System Binary Proxy Execution: Mavinject Defense Evasion [Mitre]

Adversaries may abuse mavinject.exe to proxy execution of malicious code. Mavinject.exe is the Microsoft Application Virtualization Injector, a Windows utility that can inject code into external processes as part of Microsoft Application Virtualization (App-V).

Adversaries may abuse mavinject.exe to inject malicious DLLs into running processes (i.e. Dynamic-link Library Injection), allowing for arbitrary code execution (ex. C:\Windows\system32\mavinject.exe PID /INJECTRUNNING PATH_DLL). …

AppInit DLL Injection Process Manipulating Defense Evasion [Mitre]

Any Dynamic Link Libraries (DLL) that are specified within the AppInit_DLLs registry key values are loaded by user32.dll into any process that utilizes user32.dll. So by modifying the AppInit_DLLs registry key value and pointing it to a malicious DLL, an attacker can force the system to load their DLL into every process that utilizes user32.dll and force it to execute …
