The first is bpf-linkerA simple static linker for BPF (Berkeley Packet Filter) programs. This type of technology is frequently used in observability, advanced monitoring, and traffic analysis, and its inclusion makes it easier for researchers and security teams to work with eBPF code within Kali.
Second is evil-winrm-py, a Python reimplementation of the well-known Evil-WinRM tool. Its purpose is Execute commands on remote Windows machines using WinRM (Windows Remote Management), a very common access vector in corporate environments. This utility is especially useful for red team exercises and lateral movement testing in Windows infrastructures.
The third new feature is hexstrike-ai, an MCP server designed to allow artificial intelligence agents run tools autonomouslyAlthough its use is still emerging, it opens the door to automating security testing workflows and experimenting with AI-based assistants that interact directly with the Kali toolset.
In addition, this version updates the Linux kernel to version 6.16Improving compatibility with modern hardware, including new network cards, wireless devices, and recent desktop and laptop computers, is relevant for laboratories and companies that frequently upgrade their equipment.
Kali NetHunter: More Android Devices and Wifipumpkin3
The mobile platform Kali NetHunterKali Linux, geared towards Android devices for wireless security testing and field audits, also receives significant changes in Kali Linux 2025.4. The team expands the catalog of supported phones and updates several of its key tools.
