Native OpenTelemetry

OpenTelemetry has become the standard for generating telemetry in cloud-native systems, but instrumentation alone does not guarantee observability. This article explains the difference between OpenTelemetry-compatible and OpenTelemetry-native approaches, using a Kubernetes-based Minecraft example to show how transparency in the OpenTelemetry Collector and observability pipeline improves debugging, preserves context, and restores trust in telemetry data.

When Metrics Leak Secrets: Kubernetes CTF Lessons

In this blog, I’ll walk you through how I uncovered three hidden flags in a Kubernetes cluster by investigating Grafana, VictoriaMetrics, and VictoriaLogs. Each step highlights a different misconfiguration from weak secret management to metrics leaking sensitive data, to logs revealing too much detail. I’ll also highlight the security lessons learned so you know what…
