Release summary
Kali Linux 2025.3 is now available, delivering a mix of infrastructure refreshes, wireless improvements and fresh tooling. Key highlights since the 2025.2 release include updated Packer & Vagrant support, Nexmon integration for Raspberry Pi Wi-Fi monitor/injection capabilities, and 10 new tools added to the repositories.
Packer & Vagrant — toolchain refresh
HashiCorp tooling used by many Kali workflows received updates: Packer and Vagrant have been refreshed in the distribution, improving builders and development workflows that rely on VM images and appliance automation. This benefits infrastructure-as-code users who build and distribute Kali images for labs and training.
Nexmon support — Raspberry Pi wireless injection
A major usability win for wireless testers: Kali 2025.3 adds Nexmon support enabling internal monitor mode and packet injection on Raspberry Pi built-in Wi-Fi chips. That brings affordable, fully capable wireless testing to a broader range of Pi devices and makes compact test rigs easier to deploy for red teams and wireless researchers.
Xfce VPN IP plugin — configurable interface
The Xfce VPN IP panel plugin introduced in 2024.1 gets a practical usability upgrade: you can now select which network interface the plugin monitors. Right-click the plugin → Preferences → update the “Command” parameter to choose a different interface; this is useful if you run multiple VPNs or want to monitor non-default adapters. If the plugin isn’t visible, add the “Generic Monitor” plugin via Panel Preferences → Items.
