Shellter vs Scapy: Which macOS Apps tool is Best in 2025?

Shellter is an open-source dynamic shellcode injection tool, pre-installed on Kali Linux, designed for injecting malicious code into 32-bit Windows portable executable (PE) files while evading antivirus detection. Known as a dynamic PE infector, Shellter, developed by kyREcon, allows penetration testers and red teamers to embed custom or Metasploit-generated shellcode into legitimate Windows applications without altering suspicious file attributes. Its Stealth Mode preserves the original functionality of infected executables, making it ideal for ethical hacking and security assessments.

Scapy is a versatile, open-source Python-based packet manipulation library designed for network security professionals, penetration testers, and developers. Available on Kali Linux, Scapy enables users to craft, send, capture, and analyze network packets with unparalleled precision. Unlike traditional tools, Scapy’s interactive Python interface allows for custom protocol development, network reconnaissance, and advanced packet injection, making it ideal for ethical hacking, network troubleshooting, and protocol testing.
