Shared Library Stager for Linux

stager.so Overview

stager.so is a shared library designed to securely deliver the emp3r0r agent ELF executable and execute it covertly in memory. Here's how it works:

1. Execution:
   The library creates a child process to load and execute the emp3r0r agent.

2. Use Case:
   A common method is to load stager.so into existing processes such as Nginx, SSHD, etc., to avoid detection.

Customization Instructions

1. Open ./loader/elf/stager.c and modify the following parameters:

   • HTTP Download Parameters: Update these to align with your deployment requirements.
   • AES Passphrase: Change this to a secure, unique passphrase.

2. Compile the library:

   • Run make stager_so to generate the stager.so file.

3. Deployment:

   • Use stager.so on Linux targets.
   • You'll need another stager to load the stager.so library into the desired process.
