  4. CW: release notes for Malcolm v26.08.0, a network traffic analysis tool suite for network security monitoring

    Malcolm v26.08.0 adds a NetBox purdue_zone custom field that propagates ICS/OT network zone classifications to devices, prefixes, and virtual machines (and automatically to autopopulated devices from their containing prefix); Raspberry Pi 5 support for Hedgehog Linux; and, configurable Strelka scanner and disabled-Suricata-SID lists. This release also fixes five security vulnerabilities: an nginx RBAC bypass via percent-encoded, case-varied, or slash-doubled request paths; an archive-bomb bypass affecting raw-stream and lzip-compressed uploads; a case-variant path bypass of the nginx auth gate exposing the Arkime backend to forged identity headers; an Arkime authentication gap on sensor nodes that fell back to digest instead of enforcing s2s; and a CSRF vulnerability in the kiosk /script_call endpoint allowing unauthenticated data-destructive operations. Arkime, Zeek, NetBox, OpenSearch, OpenSearch Dashboards, Logstash, Filebeat, Keycloak, and other components have been updated as well. Several other bug fixes and general improvements are also included.

    See the Release Notes for the full set of new features, enhancements, bug fixes, and component version updates.

    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.

    As always, join us on the Malcolm discussions board 💬 to engage with the community, or pop some corn 🍿 and watch a video 📼.

  5. Made a transparent network bridge on which sits between router & switch, monitoring traffic for , and capture and analyze packets → ships with ingest pipeline → setup of dashboard to visualise data is defined in flake itself so using the flake will give the same dashboard. details here codeberg.org/adingbatponder/re
