Radare2 vs Hashcat vs Nishang vs PowerShell Empire: Which AI-Powered Second Phone tool is Best in 2025?

Radare2 is an open-source, modular reverse engineering framework, pre-installed on Kali Linux at /usr/bin/r2, designed for analyzing binaries, disassembling code, and debugging software across multiple platforms. Initiated by Sergi Alvarez (pancake) in 2006, Radare2 offers a suite of command-line tools, a graphical interface (Cutter), and scripting APIs for tasks like malware analysis, firmware auditing, and exploit development. Supporting architectures such as x86, ARM, MIPS, and WebAssembly, it’s a favorite among cybersecurity researchers, ethical hackers, and CTF enthusiasts for its lightweight design and extensibility.

Hashcat is a premier open-source password cracker pre-installed in Kali Linux (version 6.2.6), tailored for cybersecurity professionals and penetration testers. This GPU-accelerated password recovery tool for security audits supports over 300 hashing algorithms, making it a leading hash-cracking tool for ethical hacking. With an 81.13 MB footprint and versatile attack modes, Hashcat empowers users to test password strength efficiently, securing systems against weak credentials.

Nishang is an open-source PowerShell framework tailored for offensive security, penetration testing, and red teaming, pre-installed on Kali Linux at /usr/share/nishang. It offers a collection of scripts and payloads designed to facilitate reconnaissance, privilege escalation, backdooring, and data exfiltration in Windows environments. Developed by Samrat Ashok, Nishang leverages PowerShell’s native integration with Windows to execute attacks in memory, evading traditional antivirus detection. Its modular structure, organized into categories like Powerpreter, Backdoors, and Gather, makes it a versatile tool for ethical hackers and security researchers.

PowerShell Empire is a robust open-source post-exploitation framework pre-installed in Kali Linux (version 6.1.2), crafted for penetration testers and red teams. This post-exploitation tool for ethical hacking leverages PowerShell and Python agents to execute stealthy attacks, making it a leading command-and-control framework for cybersecurity. With a 49.33 MB footprint and modules like Mimikatz and keyloggers, Empire offers secure communications and cross-platform support, empowering testers to simulate advanced persistent threats effectively.
