The video demonstrates how to configure and use Waza for detection engineering by setting up Sysmon to capture Windows event logs and creating custom detection rules to identify malicious activities like ransomware or info-stealers 2:22-25:59.
Key Takeaways:
• Installing and configuring Sysmon on a Windows endpoint enhances visibility into process creation and other system events, enabling richer telemetry for detection rules 2:22-3:59.
• Waza collects Sysmon logs and forwards them to a central server, where detection rules can be built using XML syntax to match specific event patterns 4:02-5:30.
• A detection rule for cipher.exe execution is created using regular expressions and a rule ID in the 100,000–120,000 range, with an if Sid tag to match Sysmon event ID 1 (process creation) 15:25-17:50.
• The rule successfully triggers when cipher.exe is executed, confirming Waza’s ability to detect native Windows tools abused for malicious purposes 24:33-25:03.
• A more advanced rule is built to detect "Deer Stealer" malware by matching registry changes and process creation events, demonstrating Waza’s capability for real-world threat hunting 27:00-29:24.
[Closing statement]
This hands-on example shows how Waza enables effective detection engineering through fine-grained, customizable rules and enhanced telemetry—making it a powerful tool for threat hunting and real-time response.

previously I released a video to Showcase wza an open-source security platform and it is extremely cool but in this video I want to chat a little bit more about detection engineering with wza so that you could build rules detection rules and generate alerts based off of malware or other malicious activity so we'll walk through one example where we can put this together and track down some of the tradecraft for malware first things first let me show you the setup of our virtual environment I have two different virtual machines running first is our Windows client really this is the endpoint where the Wasa agent will be installed and that will be the one that has malware infecting it and alongside that I have a second virtual machine set up that is our Wasa server now this is running Ubuntu L…
