Trevor Injector 4 | Simple and Secure injector for Osiris.dll for Windows 11 | (Updated 5-August-2025)

[s0mbra-1973]

Hello everyone,

Well, I've been following Daniel Krupiński and his work for many years, I'm an old school cheater, and thanks to his .DLL, I've enjoyed and learned a lot.

It's time to contribute something to the community. I see many of you going crazy trying to inject Osiris.dll into Windows 11 (I don't think anyone uses older versions of Windows, but you never know), and I know from personal experience how frustrating it is to find a working injector.

Look no further, I humbly present Trevor Injector v1.0, specifically designed for Osiris.dll.

You have all the information here: https://github.com/s0mbra-1973/Trevor

If you're in a hurry, anxious, or don't give a damn about how it was made, how it works, and other details, you can go directly to download what you're looking for: https://github.com/s0mbra-1973/Trevor/releases/download/Trevor/Trevor.zip

I hope this helps.

Best Regards,
s0mbra

WHAT`S NEW IN TREVOR INJECTOR 4 ?

Overview

Key improvements in Trevor Injector 4 (DLL injector for CS2) focusing on security, usability, performance, and maintainability.

---

🤖 Artificial Intelligence Assisted & Optimized Programming

• YES, even if you don't like it (no one is forcing you to use it), various Artificial Intelligence tools have been used during the development and optimization of the source code of this application.

---

🔒 Enhanced Security

🛡️String Obfuscation

• New: XOR encryption (XorDecrypt) for sensitive strings (e.g., cs2.exe, ntdll.dll) with key 0x55.
• Benefit: Harder static analysis detection.

🛡️Randomized Executable Name

• New: Appends random 4-char string (e.g., Trevor4_XXXX.exe) at runtime.
• Benefit: Evades signature-based detection.

🛡️Auto-Close after 5 seconds

• New: To prevent double injection.

🛡️DLL Architecture Check

• New: Validates DLL vs. process architecture match.

🛡️Randomized Delays

• New: 5-15ms sleeps between injection steps.

🛡️Secure Shellcode Cleanup

• New: Overwrites shellcode with random data before freeing.

---

🖥️ Improved User Interface

Progress Bar

• New: Visual feedback for injection steps via Progress Bar

Timestamped Logs

• New: Millisecond precision in status updates.

Injection Duration

• New: Displays process time (e.g., 1.234s).

---

🛠️ Code Modularization

Refactored ManualMapDLL

• Split into:
  • ValidatePEHeaders, AllocateProcessMemory, WriteSections, etc.
• Benefit: Easier debugging/extending.

Enhanced Errors

• Detailed messages with error codes and context.

---

✅ Conclusion

Trevor Injector 4 improves evasion, UX, and maintainability with:

• String obfuscation
• Progress tracking
• Modular code
• Forensic cleanup

The transition from Trevor Injector v3 to 4 introduces significant improvements in security, usability, and maintainability. Key enhancements include string obfuscation, randomized executable naming, a progress bar, auto-close functionality, modularized code, detailed logging, and robust error handling. These changes make the injector more secure against detection, easier to use, and more maintainable for future development.
