🚀 Advanced DLL Injector with EDR/AV/Sandbox Evasion
🔥 Overview
This project implements a stealthy DLL injector for Windows 10 and 11 with advanced evasion techniques. It includes mechanisms to bypass EDR, AV, and sandbox detections while using direct syscalls and obfuscation to reduce detection rates. The injector creates a suspended process, injects a DLL, and executes its entry point in a stealthy manner.
📌 Features
✅ Stealthy Injection: Creates a suspended process and injects a DLL without using common Windows API calls.
✅ EDR/AV/Sandbox Evasion: Implements multiple checks to detect sandbox environments, VM detection, and EDR hooks.
✅ Direct Syscalls: Uses Hell’s Gate & SysWhispers to bypass API hooks in ntdll.dll.
✅ Avoid calling GetModuleHandle: Uses PEB walk to retrieve functions in modules.
✅ Obfuscation: Base64 encoding and decoding of DLL names, function names, and suspicious artifacts.
✅ Cryptography: Implements its own cryptography functions, avoiding the usage of wincrypt
✅ Decoy Execution: The injector executes a decoy function to mimic legitimate software behavior.
🚀 Usage
1️⃣ Compilation
Requirements:
- gcc-mingw-w64-x86-64-win32
- nasm
- make
Use makefile or manual compilation below
nasm -f win64 syscalls.asm -o syscalls.o x86_64-w64-mingw32-gcc -o injector.exe dllinjector.c detector.h detector.c evasion.c evasion.h syscalls.o -Wno-array-bounds -Wall -lshlwapi -Wl,--section-alignment,4096 -Wl,--gc-sections -Wl,--strip-debug -Wl,--image-base,0x140000000 -O2 x86_64-w64-mingw32-objcopy --rename-section .CRT=.data injector.exe x86_64-w64-mingw32-strip --strip-debug --strip-unneeded injector.exe x86_64-w64-mingw32-gcc -shared -o malDLL.dll malDLL.c -Wl,--subsystem,windows -mwindows
2️⃣ Running the Injector
injector.exe C:\path\to\dll
Note: Replace
C:\path\to\dllwith the actual path of your DLL (you can use the dll in this repo for testing)
🐍 EDR, AV, and Sandbox Evasion
✅ EDR Detection (detector.c)
- Scans
C:\Windows\System32\drivers\for known EDR & AV drivers (Carbon Black, CrowdStrike, SentinelOne, etc.). - If found, decoy is executed instead of the injection.
✅ Anti-Sandbox Techniques
- Detects Virtual Machine Artifacts:
- Checks for VMware, VirtualBox, and Hyper-V files.
- Detects Sleep Patching:
- Measures the execution time of
Sleep(10000). - If altered, execution is stopped.
- Measures the execution time of
- Detects Filename Hash Matching:
- Checks if the binary filename matches its MD5 hash (common in packed malware).
- Detects Sandbox DLLs:
- Checks for the presence of sandbox’s DLLs.
✅ Anti-Debugger Techniques
- Detect if NtGlobalFlag is present in PEB.
- Detect debugger flags in HEAP

DLL Injector For Windows Download
A DLL Injector is a software program that allows you to replace invalid DLL files with legal and compatible DLLs. The program can be installed on any computer, no matter the manufacturer or operating system. It doesn’t require any special skill, so you can install it without much trouble. It works on most systems without any system requirements. Here’s how to download and install it. Read on to find out what’s involved.
Freeware
If you’re looking for a DLL injector for Windows freeware download, you’ve come to the right place. This tool is free and easy to download and install on any computer, including Windows XP and 64-bit systems. And, if you’re an avid gamer, you can try this tool to see if it works on your PC. You can also use it to introduce DLLs manually by selecting the dll file from the list and clicking “Inject”.
DLL Injector is freeware for Windows that lets you inject DLLs into running processes. The program’s easy-to-use interface makes it easy to use, and it allows developers to track running processes by process path, PID, or name. Simply click the Select DLL button, select the dll you want to inject, and the tool will display the process and error message.
Legal
A DLL Injector is software that allows you to force an external file or code into running processes so that they can be changed or altered. This software has a simple and intuitive user interface and allows you to choose which processor DLL to inject. If you are not sure how to insert the DLL, it is also possible to manually insert it into the process. There are some advantages of this software, though.
The process of injecting a DLL into a process is either peaceful or destructive. It may be done for various purposes, including antivirus analysis, application improvement, or application maintenance. The only difference is the reason for the injection. There are good reasons for doing so, and the process is entirely legal. If you want to inject a DLL into an application, you should first obtain the source code for that DLL.
Tested
DLL Injection is a great way to bypass the security of some processes and inject malicious code into another process. In fact, the injected code opens a dialog box for you to confirm its injection. A worm can use this technique to subclass windows and install detours around the system APIs.
Though not essential for the Windows OS, this file can cause a few problems. To fix this issue, simply reinstall the Visual C++ Redistribution. In the case of the injected DLL in Win7, the virtual machine cannot run.
Another free DLL Injector for Windows is Xenos Injector. It’s a very small download, which can work on Windows 7 and up. The program is compatible with all major versions of Windows, and you can download it for free from the official website. If you’re looking for an effective program to help you fix DLL errors on Windows, Xenos Injector is worth a look.
Easy to use
If you’re looking for an easy-to-use DLL injector for Windows, look no further. There are many tools on the market, but which one is right for you? There are many factors to consider, including efficiency, size, user interface, and ease of use. Remote DLL, for example, is one of the most reliable tools for DLL injection. Its user-friendly interface makes it very easy to use, and it offers multiple injection methods.
The main feature of the Easy to Use DLL injector for Windows is its ease of use. This software has been hailed as a game cheating tool by game developers and enthusiasts alike. The program is available for both Windows and Linux, and it’s easy to see why. While there are many DLL injectors available, few are as easy to use and effective as LoadLibrary.
Reliable
DLL injection is a process of changing the behavior of a program by inserting external code. DLL Injector is a Windows application that forces external code into processes. This process cannot be performed manually.
DLL Injector is useful for gaming as well as advanced applications. It has been used by thousands of developers worldwide. If your application is not performing properly, try injecting a DLL to fix the problem.
There are two ways to inject a DLL: manually or through a DLL injector software. Manually introducing a DLL will be slow and ineffective, while automatic DLL injection will save you time and effort.
However, DLL injection software is faster, more reliable, and error-free, and requires no special skills. It works on virtually all computers, so you can use it on any computer.
Abort Injection option
There are several benefits of using a DLL Injector for Windows. DLL Injectors are programs that allow you to change the behavior of any Windows program by modifying its internal code.
The Abort Injection option allows you to end the injection process. Among these benefits are ease of use and easy customization. To install DLL Injector for Windows, you can follow the steps below.
The DLLs are stored in the HKEY_LOCAL_MACHINESYSTEMSYSTEMCurrentControlSetControlSessionManagerAppCertDLLs folder. Every time a process uses a Win32 API function, it loads a DLL that is signed by a valid certificate. In addition to this, DLLs are linked to external symbols of the program and can be compiled with the -fpic option.
At first, you need to understand what a dynamic-link library (DLL) is before jumping into the DDL injection part. A DLL is a file through which users can easily share code with other resources in order to perform particular tasks. This is an external library of functions that holds all the information which can be accessed by different kinds of software processes. If you want to add a custom function or feature in a software, you need to do it with DLL Injector Download.
With such software, you can save memory as it is only loaded when required and can be used by different programs simultaneously. Hence why it is important to only use the 10 best DLL injectors for specific apps and games like Robox and CSGO!
The initial starting process loads libraries from different places in the physical library. These are loaded by the following locations:
- Application path directory.
- Windows directory path returned by GetWindowsDirectory.
- System directory path in Windows directory.
- Directories path in environment variables.
How a DDL Injector Works
This is a technique through which you can run any code in the memory of another process by forcing it to load a foreign DLL file. Now, if you want to attach it to a process you need to use the software “Injector” to mount libraries in memory allocated by the program. DLL injection is used to reverse engineering applications commonly without using the source code, whenever the need for modifications or behavior of those apps changes.
Moreover, it is also useful in hot-patching as it allows you to update a part of the code without shutting down and restarting the process. Remember that most system viruses can use it to get information such as malware software. Many antiviruses should prevent it from happening but if you are less careful then you need to be aware of all the suspicious software.
In our testing, we found that AVG, Avast, BitDefender and CrowdStrike had flagged various of the below. We recommend you disable them temporarily before using them.
Different Methods of DLL Injection
DLL Injectors use a variety of injection methods to work, below are the ones used by the likes of DLL Injector for hacking into games.
DLL Replacement
A simple method in which we prepare and compile a library swap with the original inserted DLL with modified code needs to have a function with the same signatures as the original one.
Modifying Windows Registry
This one uses User32.dll which is used to implement a graphical user interface to program. Many Windows app uses this. Now, during initialization what the library does is check the registry for the Boolean key in the registry.
If you have administrative privileges, then you need to add them to inject them into the list. You need to be aware of the fact the DLL is mapped to all the processes that use User32.dll, so initializing it with infinite loops or incorrect memory access can crash the inherited processes.
This is a similar method to how network hacking scripts work, where they try to replace legitimate packets with malicious ones.
Windows Hooks
These are system message-handling mechanism that allows Windows to catch function calls between windows or evens there from inputs such as a mouse or keyboard. This is similar to the process of Keyloggers that keep track of the keys you press on the keyboard which are then sent to the origin.
The pieces of code which are implemented in Hooks are used when the events are invoked by sending in a certain message to the programs like web browsers or other GUI apps. However, there is a possibility to create a keylogger that registers all the pressed keys.
Remote Threads
Using these in contrast to the ones used in the previous methods, this one allows you to set certain target processes and the time of the attack. The injection carries a passing string path of injected DLL towards the target app known as the CreatRemoteThread function, along with using the method of LocalLibrary.
This has seemed to be one of the most flexible methods but it needs knowledge of many Windows features such as processes, threads and virtual memory management.
