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.

Malcolm v25.11.0

Malcolm v25.11.0 includes an overhaul of the install.py installation/configuration script, a few bug fixes, and some component version updates.

v25.09.0...v25.11.0

  • ✨ Features and enhancements
    • We're in the process of majorly overhauling our install.py script (#395) used for setting up a Linux or MacOS system to run Malcolm and for configuring Malcolm's runtime options. There are future updates still to come (#766) but for now the command-line and dialog-based interfaces' functionality and backend are in place. The step-by-step wizard has been replaced with a menu-based interface that allows for changing individual values without having to step through the whole set of questions. The Docker-based Malcolm installation example on Ubuntu and end-to-end installation example have useful information about this change, as does the command-line arguments document. We've done a lot of testing on what's a complete rewrite of this, but there is a possibility we missed something; if you find an issue with the new install/configure script, please open a discussion or log a bug and let us know. For the next release or so, we're leaving the legacy installer in place as scripts/legacy_install.py which could be used in a pinch (e.g., run scripts/legacy_install.py --configure for the old configuration menu).
    • We've incorporated a new "Connections Tree" visualization. This visualization tracks the potential of lateral movement based on the observed communications between all devices that reach a root node, identified by IP address. It gives a high-level view showing both direct and indirect connetions between the root IP and all of its destinations, regardless of time, along with enriched data for each endpoint and connection.
    • Updates to the Validated Design Architecture Review (VADR) dashboards.
    • The OpenSearch container now includes the repository-s3 plugin, useful for those who wish to configure OpenSearch's snapshots to save to S3-compatible buckets.
  • ✅ Component version updates
  • 🐛 Bug fixes
    • Double imports when restarting Malcolm (#588) (thanks @KchChr)
  • 🧹 Code and project maintenance
    • Refactored a number of Python functions to reduce cyclomatic complexity (#765, work ongoing)
  • 📄 Configuration changes (in environment variables in ./config/) for Malcolm and in control_vars.conf for Hedgehog Linux. The Malcolm control script (e.g., ./scripts/status, ./scripts/start, etc.) should take care of creating new variables and migrating existing ones as needed based on the rules in ./config/env-var-actions.yml without intervention on the user's part.
    • Malcolm
      • NGINX_RESOLVER_IPV4_OFF and NGINX_RESOLVER_IPV6_OFF have been renamed to NGINX_RESOLVER_IPV4 and NGINX_RESOLVER_IPV6, respectively, and their logic reversed, in nginx.env.

Malcolm v25.08.0

Malcolm v25.08.0 is a minor release fixing a regression bug inadvertently introduced in v25.07.0.

v25.07.0...v25.08.0

If you are updating from a version older than v25.06.0, please read those release notes prior to updating to this version.

  • ✨ Features and enhancements
    • Performance improvements to the clean-processed-folder.py script in the filebeat container responsible for pruning already-processed Zeek and Suricata log files (#736)
  • 🐛 Bug fixes
    • Malcolm fields are not created in Arkime (#735)
      • Due to this commit, the order in which the Arkime fields database was initialized and the WISE service started was switched, which resulted in the initial run of capture (responsible for populating Malcolm's custom fields) failing. The order of these operations has been corrected.
  • 📄 Configuration changes (in environment variables in ./config/) for Malcolm. The Malcolm control script (e.g., ./scripts/status, ./scripts/start, etc.) should take care of creating new variables and migrating existing ones as needed based on the rules in ./config/env-var-actions.yml.
    • FILEBEAT_CLEANUP_VERBOSITY and added to filebeat.env to control the verbosity of the clean-processed-folder.py script mentioned above in relation to #736. For example, setting FILEBEAT_CLEANUP_VERBOSITY=-vvvv corresponds to the DEBUG log level, and will produce output like this once per minute:
    filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Found 2099 Zeek processed directory files to consider.
filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Found 135 Zeek live directory files to consider.
filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Checked 2099 Zeek processed directory files at a rate of 10804 files/second.
filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Checked 135 Zeek live directory files at a rate of 1411 files/second.
filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Found 161 Suricata files to consider.
filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Checked 161 Suricata files at a rate of 18018 files/second.
filebeat-1  | 2025-08-07T20:23:00Z  /usr/local/bin/clean-processed-folder.py: Finished pruning files.

Malcolm v25.06.0

Malcolm v25.06.0 includes a some new and oft-requested features, bug fixes, and component version bumps.

v25.05.0...v25.06.0

NOTE: As this Malcolm release enables the OpenSearch Security Plugin as described below, even inter-container access to OpenSearch must now be authenticated when using Malcolm's embedded OpenSearch instance. To accomplish this, an internal-use-only account and password is used for connecting to OpenSearch by Malcolm's other components as needed. This credential (saved in .opensearch.primary.curlrc in the Malcolm installation directory) needs to be generated before Malcolm starts up the first time after upgrading. To do so, please run ./scripts/auth_setup and select (Re)generate internal passwords for local primary OpenSearch instance. This credential is only used internally for OpenSearch and cannot be used to remotely access Malcolm.

  • ✨ Features and enhancements
    • This release adds role-based access control (RBAC) to Malcolm (#460).
      • Malcolm's RBAC feature is based on Keycloak realm roles and is implemented in to layers:
        1. Whenever possible, Malcolm's backend Keycloak realm roles are mapped to the roles/groups/permissions features provided by the components that make up Malcolm, for example:
        2. For other Malcolm components that don't implement their own permission management systems, Malcolm handles the enforcement roles based on request URIs in its NGINX proxy layer.
      • This is an optional feature. RBAC is only available when the authentication method is keycloak or keycloak_remote. With other authentication methods such as HTTP basic or LDAP, or when RBAC is disabled, all Malcolm users effectively have administrator privileges.
      • Because the OpenSearch Security Plugin requires TLS even internally, Malcolm's internal connections to the embedded OpenSearch instance, when used, are now all performed over HTTPS. However, this is all handled internally and should not behave or appear different to the user than it did in previous versions.
      • See the role-based access control documentation for more information on this feature.
    • Malcolm's embedded KeyCloak instance now automatically creates and configures the default client by ID, if specified in ./config/keycloak.env.
    • Allow user to specify subnet filters for NetBox autopopulation (#634)
      • This feature is especially useful for excluding dynamic address ranges such as those used by DHCP, which should generally not trigger autopopulation in NetBox. Since these addresses can change frequently and aren't tied to specific devices, including them could result in inaccurate or noisy inventory data. By fine-tuning which private subnets are included or excluded, users can ensure that only meaningful, typically static assignments are autopopulated.
    • Expose init arguments for Arkime's db.pl and also use them for Malcolm's creation of its own index templates (#692)
    • Extend Zeek's intel.log with additional fields using corelight/ExtendIntel (part 1) (#502)
      • This integrates the corelight/ExtendIntel plugin into Malcolm internally but does not significantly change how Malcolm presents intel.log to the user. Further work to do so will be continued in #695.
    • Some internal tweaks to the PCAP processing pipeline that are going to be leveraged by the Malcolm-Helm project (idaholab#630)
    • Handle a fix in the ICSNPP OPCUA-Binary plugin that adds a new sec_token_id field (cisagov/icsnpp-opcua-binary#101)
    • Moved the configuration for Zeek's use of the zeek-kafka plugin to its own file (kafka.zeek) to make it easier to override in Docker using a volume bind mount or in K8s using a configMap.
    • Changed some internal objects used for NetBox enrichment caching from Ruby's Concurrent::Hash to Concurrent::Map for better performance
    • Minor improvements to the icons, shortcuts, and convenience bash functions in the ISO-installed Malcolm desktop environment
    • NGINX now generates a robots.txt file to avoid web crawlers
  • ✅ Component version updates
  • 🐛 Bug fixes
    • NetBox autodiscovery no longer populating host name from DNS, DHCP, NTLM (regression, #699)
    • documentation served at /readme is trying to pull fonts from use.fontawesome.com (#694)
    • support fractional gigabytes correctly when generating Arkime's config.ini setting maxFileSizeG from PCAP_ROTATE_MEGABYTES
    • Improved logstash filters that calculate unique hashes used as document IDs for Zeek and Suricata logs to better prevent duplicate logs from being written to the document store
  • 📄 Configuration changes (in environment variables in ./config/) for Malcolm and in control_vars.conf for Hedgehog Linux. The Malcolm control script (e.g., ./scripts/status, ./scripts/start, etc.) should take care of creating new variables and migrating existing ones as needed based on the rules in ./config/env-var-actions.yml.

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.
