Malcolm v26.06.0 (contains critical security fixes)

[mmguero]

Malcolm v26.06.0 is primarily a security hardening release, addressing fifteen vulnerabilities (2 high severity, 6 medium, and 7 low) identified in a security assessment. Bug fixes address an issue with the zeek container causing performance degredation over time and a fix for duplicate virtual machine entries in NetBox autopopulation. A few component versions have also been updated.

If you are upgrading from an existing Malcolm installation, run ./scripts/status for Malcolm to migrate some settings prior to running ./scripts/configure, ./scripts/start, or other Malcolm control scripts.

Malcolm is a powerful, easily deployable network 🖧 traffic analysis tool suite for network security monitoring 🕵🏻‍♀️.

Malcolm operates as a cluster of containers 📦, isolated sandboxes which each serve a dedicated function of the system. This makes Malcolm deployable with frameworks like Docker 🐋, Podman 🦭, and Kubernetes ⎈. Check out the Quick Start guide for examples on how to get up and running.

Alternatively, dedicated official ISO installer images 💿 for Malcolm and Hedgehog Linux 🦔 can be downloaded from Malcolm's releases page on GitHub. Due to limits on individual files in GitHub releases, these ISO files have been split 🪓 into 2GB chunks and can be reassembled with scripts provided for both Bash 🐧 (release_cleaver.sh) and PowerShell 🪟 (release_cleaver.ps1). See Downloading Malcolm - Installer ISOs for instructions.
