NetCut (originally developed by Arcai.com) gained popularity in the mid-2000s as a user-friendly tool for network administrators to block unwanted devices on local networks. Unlike professional switch management, NetCut exploits ARP protocol weaknesses to interrupt connections. Old versions (e.g., 2.x, 1.5) are still circulated on third-party repositories, often bundled with adware or without source verification. This paper reviews their operational mechanics, known vulnerabilities, and ethical considerations.

NetCut, a network utility designed for Address Resolution Protocol (ARP) spoofing and network monitoring, has seen significant evolution over the past decade. While modern versions incorporate updated features and security patches, older versions (pre-3.0) remain in use in legacy systems, educational demonstrations, and malicious toolkits. This paper examines the technical characteristics, security flaws, and operational risks associated with old NetCut versions, arguing that their continued use poses disproportionate network integrity risks compared to modern alternatives.

| Feature | Old NetCut (v1.5–2.5) | Modern Alternative (e.g., xarp, arpwatch) | | --- | --- | --- | | ARP cache poisoning detection | None | Active monitoring | | Packet signature obfuscation | No (plaintext ARP frames) | Optional encryption | | Source code integrity | Unverifiable, often trojaned | Open-source / signed | | Operating system support | Windows XP/Vista/7 (32-bit) | Cross-platform | | Automatic ARP recovery | Broken in many builds | Reliable |

An Analysis of Legacy NetCut Versions: Functionality, Vulnerabilities, and Mitigation in Legacy LAN Environments

Specifically, old versions do not implement sequence number checks, VLAN-aware spoofing, or protection against reverse ARP detection. They are trivially detected by arp -a anomalies or static ARP entries.
