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...

Handling backend restarts in Cloudflare Realtime SFU

Cloudflare Realtime WebSocket adapter handles brief backend restarts better than I expected, but only within a hard five-second window. That is enough to turn a wobble into a pause; after that, the...

Detect Split ClientHello failures in TLS 1.3

Split ClientHello failures are exactly the sort of thing that waste an afternoon, because the server looks fine until a fragmented post-quantum handshake trips over something in the middle. TLS...

Checking Logpush field mappings after schema updates

Cloudflare Logpush datasets do not always announce when they change shape, and that is where the trouble starts. I check the field map against real exports, because a parser that still runs can be...

Local DNS proxy now preserves DNSSEC records

Cloudflare One Client for Windows now leaves DNSSEC records alone, which is exactly the sort of change I like, because it stops the client quietly meddling with answers. I have seen enough broken name...

Cloudflare One Client for macOS DNS search suffixes

Cloudflare One Client for macOS can make a short hostname behave very differently, and most of the pain sits in the suffix list rather than DNS itself. I have seen perfectly sane machines fail because...

Tracing acme.sh certificate handling in TLS interception

I spent too long chasing the neat version of TLS wiretapping reconstruction, then found the mess: shell parsing, token limits, and renewal timing. The interesting bit is not the packet capture, it is...

Reverse engineering game binaries with static analysis

Game binaries give up more than they should, if you know where to look. I start with binary analysis, not the folklore around the game, then use strings, imports, and control flow to separate real...

Agentic AI still needs domain judgement

Agentic AI can write the thing, but it still cannot tell you whether the thing is right. That is where domain expertise matters, because a clean config or neat bit of glue logic can still be wrong in...

wolfCOSE zero-allocation parsing in embedded C

wolfCOSE looks sensible only if you care about what your firmware actually has to carry. I like that, because on small targets the wrong crypto feature can cost more than the message itself, and there...
