Offensive Security has released Kali Linux 2021.3. The new build brings wide OpenSSL compatibility, better Virtual Machine support, new tools, and a lot more. Here’s everything you need to know.

Kali Linux 2021.3 Features and Improvements


The new build comes with a wide OpenSSL compatibility by default. This enables Kali to talk to ancient systems that are still using legacy protocols like TLS 1.0 and TLS 1.1. Old ciphers are also enabled by default. It’s a great addition as it’ll allow the OS to talk to more systems.

Virtualization Improvements

Functions like copy-paste, drag, and drop between host and guest are available. This feature works on almost all of the popular VMM’s in the market — VMware, VirtualBox, Hyper-V, and QEMU+Spice. Apart from that, you can now easily configure Kali for Hyper-V Enhanced Session Mode.

New Tools

Here’s the list of all the new tools that have been added.

  • Berate_ap – Orchestrating MANA rogue Wi-Fi Access Points
  • CALDERA – Scalable automated adversary emulation platform
  • EAPHammer – Targeted evil twin attacks against WPA2-Enterprise Wi-Fi networks
  • HostHunter – Recon tool for discovering hostnames using OSINT techniques
  • RouterKeygenPC – Generate default WPA/WEP Wi-Fi keys
  • Subjack – Subdomain takeover
  • WPA_Sycophant – Evil client portion of EAP relay attack

You can read more about each of them on the Kali Linux blog.

Kali NetHunter Watch

Mobvoi’s Ticwatch Pro now has NetHunter support. The company says that its features are limited to USB attacks as the hardware has its own limitations, such as a small battery.

Apart from that, there are many theming changes and improvements that you can read more about in the official release post.
