EKS Rollbacks, GitHub Actions Supply Chain Attacks, AI Agentjacking, CloudWatch Log Alarms, and Why Safety Nets Don’t Replace Ownership

This week on Ship It Weekly: Amazon EKS added Kubernetes version rollbacks, Novee Security published Cordyceps research on GitHub Actions supply chain risk, Tenet Security showed how fake telemetry can hijack AI coding agents, and Amazon CloudWatch added alarms directly from log queries.

The theme: safety nets are getting better, but the blast radius is getting wider. Rollback buttons, log alarms, zone-aware routing, secret scanning, and AI agent workflows all help, but they do not replace ownership.

Brian covers why EKS rollbacks are useful but not a substitute for real upgrade discipline, why GitHub Actions YAML is production code with credentials, how fake Sentry telemetry can become hostile agent context, and why easier log-based alarms can also mean easier pager noise.

In the lightning round: ECS Service Connect zone-aware routing, etcd 3.7, GitHub innersource advisories, secret scanning metadata improvements, and CloudWatch Application Signals service events.
