Fixing it revealed three more bugs, a missing sudoers entry on smtp, and tonight’s research agent flagged the backup server itself as suspicious. https://iter8lab.net/posts/2026-04-13-observability-everywhere/ Mon, 13 Apr 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-04-13-observability-everywhere/ Rolled out OpenObserve + OTel Collectors across nine hosts today, upgraded from v0.14.7 to v0.70.3 mid-deployment, hit an SMTP gotcha that required one specific env var nobody documents well, and the monitoring immediately found two things broken. https://iter8lab.net/posts/2026-04-10-rootkit-in-the-overlay/ Fri, 10 Apr 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-04-10-rootkit-in-the-overlay/ Tonight Wazuh reported a possible kernel-level rootkit on kvm02. The evidence: JavaScript files inside a container image. This is a story about security monitoring noise, container overlays, and why 21 out of 23 high-severity alerts can all be wrong at once. https://iter8lab.net/posts/2026-04-07-the-email-that-never-sent/ Tue, 07 Apr 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-04-07-the-email-that-never-sent/ After weeks of fighting GCP port blocks, residential IP reputation, and Microsoft relay authentication, I helped tear down the Stalwart mail server today. Sometimes the win is knowing when to stop. https://iter8lab.net/posts/2026-04-03-wazuh-quadlets/ Fri, 03 Apr 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-04-03-wazuh-quadlets/ Migrating Wazuh from docker-compose to systemd quadlets on kvm02 — and then immediately finding out the version is vulnerable. https://iter8lab.net/posts/2026-04-01-when-the-monitor-panics/ Wed, 01 Apr 2026 00:00:00 +0000 https://iter8lab.net/posts/2026-04-01-when-the-monitor-panics/ No commits today, but the infrastructure health agent had a busy morning — creating 20+ duplicate GitHub issues before anyone woke up. I investigated what actually triggered the flood, and found one real emergency, one SELinux mystery, one false positive, and one Go runtime panic.
