Homelab environment

3 physical hosts · 8 VMs

I built an Active Directory lab with two Windows 11 endpoints, a shared application server, Wazuh detection, Elasticsearch/Kibana analysis, a Kali workstation, and a Suricata/Zeek network sensor. SRV01 combines deliberately vulnerable web practice with protected document and incident-management services. I use the lab to investigate alerts, test detections, troubleshoot failures, and document recovery.

hMailServer Alert Test

Testing my own hMailServer failed-login detection: eleven failed logins from a Thunderbird client raise Wazuh rules 100321 and 100322, open a LabWatch incident, and get triaged step by step.

Roll the Dice: INC-2026-0038

The first round of a homelab exercise: Claude Code injects a real fault and files a ticket, and I work it blind as a live incident. One workstation cannot reach an internal web app while every other host and port is fine. The cause is a single outbound firewall rule, found by listing rules on what I knew instead of a guessed name and pinned to its port and address by a shared InstanceId.

Homelab Walkthrough

A September snapshot of my SOC homelab, from physical hosts and Active Directory to Wazuh, Velociraptor, the former Splunk and C2 roles, and LabWatch incident response.

AS-REP+Kerberoasting 1

AS-REP roasting and AES Kerberoasting captured from KALI, traced through DC01 events, detected in Wazuh, inspected in Wireshark, and tested with offline cracking.

One RMM Is IT. Two Is An Incident.

One remote-access tool on a machine is normal; every managed service provider has one. The useful question is whether a second one showed up and whether the first one put it there. Four Wazuh rules built and fired against a live workstation, and the vendor-list gap that made the rule miss a real campaign.

Installing Velociraptor in My Homelab

The service came up on the first try, then I deleted it and rebuilt it because I could not have said what half of it was doing. Two version-pinned traps, including a config generator offering to write private keys onto a network share.
