ShellTer — A Dynamic Shellcode Injection Tool

Convert Text to Speech

ShellTer is an iptables-based firewall. What sets it apart from the rest is that it has built-in SSH brute force protection. It is simple to organize as well as it has an interactive CLI installer.

Shellter is a dynamic shellcode injection tool as well as possibly it was the first dynamic PE infector ever generated. It can be used in order to insert shellcode into local Windows applications that have recently 32-bit apps only. Even the shellcode can be something yours or something created via a framework just like Metasploit.
Shellter takes benefit of the real structure of the PE file as well as it does not affect any modification just like modifying the memory access permissions in sections except the user wants, adding an extra section with RWE access,and whatever it would look corrupt under an AV scan.
Shellter uses a unique dynamic approach that is based on the execution flow of  the target application. It means that there are no static/predefined locations that are used for shellcode injection. Shellter will start and also trace the target when at the same time will log the execution flow of the application.
System Requirements:
It is suggested that you use Windows XP SP3 (32/64-bit) and above.
CPU: The better the faster. It’s only a matter of time.
  • Tracing 1 million instructions without Thread Context logging => ~ 6 MBs
  • Tracing 1 million instructions with Thread Context logging => ~ 28 MBs
  • Tracing 10 million instructions without Thread Context logging => ~ 40 MBs
  • Tracing 10 million instructions with Thread Context logging => ~ 27
