PoshC2 vs Sslstrip vs Fern-Wifi-Cracker: Which Firmware Analysis Tool tool is Best in 2025?

PoshC2 is an open-source, proxy-aware command and control (C2) framework designed for penetration testing and red teaming, pre-installed on Kali Linux at /usr/share/poshc2. Primarily written in Python3, it offers a modular architecture that supports PowerShell, C#, C++, and Python3 implants, enabling post-exploitation and lateral movement across Windows, Linux, and macOS systems. Developed by Nettitude Labs, PoshC2 provides highly configurable payloads, extensive logging, and Docker support for cross-platform deployment.

Sslstrip is an open-source cybersecurity tool designed for executing HTTPS downgrade attacks, enabling man-in-the-middle (MITM) interception of supposedly secure web traffic.Sslstrip is widely used by ethical hackers and penetration testers to test network security by stripping SSL/TLS encryption from HTTPS connections and redirecting them to unencrypted HTTP. This allows attackers to capture sensitive data like login credentials in controlled environments.

Fern-Wifi-Cracker is a powerful open-source wireless network auditing tool for ethical hacking, integrated into Kali Linux (version 2024.06.R1). As a GUI-based Wi-Fi penetration testing software, it cracks WEP, WPA, WPA2, and WPS keys, making it a premier wireless password-cracking tool for cybersecurity. Written in Python with a Python Qt GUI, its 1.13 MB size and automation features simplify wireless security assessments for professionals and beginners alike.
