Malcolm v24.05.0 contains new features, improvements, bug fixes and component version updates.

v24.04.0...v24.05.0

  • Features and enhancements
    • Added ARM64/AArch64 support. Malcolm can now run natively on ARM64 hardware. The ./scripts/configure script should detect the architecture and automatically adjust the image: names in the docker-compose.yml files in Docker deployments, or this can be changed manually by appending -arm64 to the tag for Malcolm's Docker images, e.g., ghcr.io/idaholab/malcolm/zeek:24.05.0-arm64. (idaholab#369)
    • Support for new environment variables added to Hedgehog Linux's control_vars.conf for tuning capture-related settings for Arkime on the sensor, bringing them into parity with those that were available in the arkime-live container in Malcolm. (idaholab#476)
    • Tweaked some of the default resource-related live capture settings for Suricata and Arkime.
    • Reworked the environment variables used for tuning Zeek live capture resource and performance on both Malcolm and Hedgehog Linux. An in-depth discussion of these tuning parameters can be found in the documentation. (idaholab#475)
    • Allow setting the spiDataMaxIndexes variable for Arkime's config.ini file via the ARKIME_SPI_DATA_MAX_INDICES environment variable. (idaholab#471)
    • Allow custom tags to be specified at the point of log file ingestion (i.e., FileBeat) on Malcolm and Hedgehog Linux. This makes it easier to specify custom tags used to group network traffic by sensor. (idaholab#463)
    • Handle invalid URLs made to the Malcolm web-based UIs better (with a custom 404/502 page). (idaholab#461)
    • Switched to official .deb packages for Arkime rather than building from source, reducing build times significantly. (Thanks @awick.)
  • Component version updates
    • Suricata to v7.0.5
      • Also, going forward Malcolm will track the latest Suricata release (from the Debian Stable Backports APT repository) rather than what's in the Debian Stable APT repository. (idaholab#462)
    • Arkime to v5.2.0
    • OpenSearch and OpenSearch Dashboards to v2.14.0
    • YARA to v4.5.1
    • Beats to v8.13.4
    • Logstash to v8.13.4
    • YQ to v4.44.1
    • Zeek to v6.2.1
    • Fluent Bit to v3.0.6
    • requests Python library to v2.32.0 for CVE-2024-35195
    • flask-cors Python library on Hedgehog Linux to v4.0.1 for CVE-2024-1681
    • Jinja Python library on Hedgehog Linux to v3.1.4 for CVE-2024-34064
    • Werkzeug Python library on Hedgehog linux to v3.0.3 for CVE-2024-34069
  • Bug fixes
    • The code that cleans up already-processed Zeek and Suricata logs after a defined period of time was out of date for the current FileBeat registry behavior and would potentially leave log files around longer than they needed to be. This has been remedied. (idaholab#479)
    • Fixed issue where the BPF capture filter was not passed to Zeek correctly. (idaholab#474)
    • The process which queries threat intelligence feeds and generates the corresponding Zeek intel files will no longer relpace existing intel definitions unless it succeeds in pulling definitions from at least one of the specified feeds. (idaholab#472)
    • Fixed calculation of memory and CPU resources used in ./scripts/status for Kubernetes deployment. (idaholab#467)
  • Configuration changes (in environment variables in ./config/) for Malcolm and in control_vars.conf for Hedgehog Linux
    • Malcolm
      • Added ARKIME_SPI_DATA_MAX_INDICES to arkime.env with a default value of 7, which manifests as spiDataMaxIndexes in Arkime's config.ini. If you are changing the Arkime index period from daily to weekly, hourly, etc., you may wish to adjust this value. (idaholab#471)
      • Added EXTRA_TAGS to upload-common.env for specifying custom tags to be associated with logs forwarded to Logstash by FileBeat. (idaholab#463)
      • A number of new and modified environment variables are available and can be added to zeek-live.env for tuning the resource utilization and performance of Zeek's live capture, see the documentation for details. (idaholab#475)
    • Hedgehog Linux

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.
