Headlamp in-cluster deployment and RBAC boundaries

Headlamp in-cluster deployment only makes sense when the UI belongs inside the cluster, and even then the service account should be painfully narrow. I trust the boundary, not the person using it on a quiet afternoon.

Marketplace takedown pressure on vendor operations

Marketplace takedowns do more than pull a site offline, they cut through the vendor routines that keep sales moving. In dark web marketplaces, that...

Brickstorm persistence in Microsoft 365

Brickstorm showed how Microsoft 365 persistence can survive a tidy password reset and a few blocked logins. I keep coming back to the same point, if...

Restricting Serv-U access before patching

The SolarWinds Serv-U flaw is the sort of bug that turns a routine patch into an ugly afternoon, so I would block the obvious request pattern first...

Topology-aware scheduling with PodGroup and DRA

Kubernetes PodGroup scheduling only makes sense once you stop treating the group as a template trick and start treating it as live state. I like that split, because it forces the scheduler to deal...

Kubernetes Service externalIPs deprecation and replacements

Kubernetes Service externalIPs has always been a bit too trusting for my taste, and 1.36 finally starts treating it that way. If you still rely on it, now is the time to move the address ownership...

Mixed Version Proxy during Kubernetes 1.36 upgrades

Measuring route_controller_route_sync_total in Kubernetes

`route_controller_route_sync_total` is the sort of metric I trust only when I put it next to real node activity. By itself it tells you little; alongside churn, it shows whether the route controller...

Incident response after GitHub code exposure

A GitHub internal repositories breach rarely starts with the code itself, it starts with a weak boundary and ends in places people forgot to check. I care less about the headlines than the tokens,...

Rebuild WinRE trust after CVE-2026-33825 changes

BitLocker zero-day mitigations are easy to half-apply and then forget, which is exactly how trouble lingers. I had to rebuild WinRE trust after CVE-2026-33825 changes, because removing autofstx.exe is...

Malicious VS Code extensions and workstation compromise

Malicious VS Code extensions do not need to look suspicious to do damage. I care less about the marketplace listing and more about what the thing can reach once it is installed, because that is where...

Arch Linux PinTheft patch validation steps

PinTheft Arch Linux root escalation is only interesting if the kernel still exposes RDS, so I start there, not with exploit code. If the patched build really closes the hole, it should fail cleanly,...

Least privilege for agentic AI tool calling

Agentic AI is easiest to trust when it has very little to do, and even less power. I prefer to treat tool calling like any other risky admin path, with tight permissions, short-lived credentials, and...
