If you’re a #dominos person: my daughter’s #highschool band is doing a #fundraiser with these #BOGO “Slice the Price” cards.

Here's the link.

• $20 (plus like a buck shipping)
• Buy a large pizza at menu price → get a large FREE
  
• Works for double the large pizzas no matter how many you order
  
• Unlimited uses through 12/31/2026
  
• Valid at 2,609 Domino’s stores in 42 states (map on the site)
  
• Works in-person, call-in, online, and in the Domino’s app

No pressure—just sharing in case anybody reading this likes #pizza and wants to eat twice as much of it without paying more money.

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

https://github.com/idaholab/Malcolm/compare/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
  • Arkime to v5.8.2
  • Fluent Bit to v4.1.1
  • Keycloak to v26.4.2
  • OpenResty to v1.27.1.2
  • OpenSearch Dashboards to v3.3.0
  • OpenSearch to v3.3.2
  • supercronic to v0.2.38
  • yq to v4.48.1
  • Zeek to v8.0.3
• 🐛 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.

Building a network traffic analysis system: Deploying Malcolm on Amazon EC2

This is the first of two blog posts on the AWS Public Sector Blog about deploying Malcolm on Amazon AWS. It covers installing Malcolm on a single EC2 instance. The next post will cover deploying Malcolm on EKS.

For those of you more interested in scaling Malcolm using Kubernetes, you can check out our "still-in-beta" Helm chart and share your feedback in the issue tracker on that repo.

My team develops #Zeek network analyzers for #OT protocols (see ICSNPP on GitHub). If you're familiar with this work, you know one of the hardest parts about it is getting sample data. If you've got access to traffic for some of the more niche protocols on our list (BSAP, ANSI C12.22, GE-SRTP, GENISYS, ROC Plus, Synchrophasor, etc.) and are willing and able to share a bit of PCAP, would you please reach out to me?

#operationaltechnology #ics #icssecurity #PCAP

Hey, y'all, if you have anything to do with the Zeek network security monitor (as a user, script/plugin developer, researcher, whatever), would you please take 10 minutes to fill out the Zeek Project Survey 2025. This is your chance to help the Zeek team know how you feel about the project and help shape its direction moving forward.
