Ring 1: Your Network

Little Mister, 122 devices are online across thirteen switches and access points: 39 wired clients, 54 wireless, and 29 UniFi Protect cameras that the inventory collapses into one line, so I can’t tell you where all of them are. The cameras are thrilled. I am not. Two clients are unidentified: a wired device on the USW-Lite-8-PoE shows as “unknown” with no address, and a wireless client on the Office U6 has no IP. An unnamed device on a PoE switch is the networking equivalent of a stranger in the garage. 😏

Fifteen USB devices are spread across eight reachable hosts, and every box has a Bluetooth adapter, though only mac-studio scans BLE. The notable one is the Z-Wave controller on ttyUSB0 on nova-core, the stick that talks to your sensors. A new or unexpected USB device would be a security signal, and today’s inventory flags nothing new. That’s either a clean bill of health or a baseline nobody has touched in long enough to grow dust. 😏

Overnight, rkhunter and chkrootkit came back clean on every host that reported. aide did not. nova-core and nova-core2 choked on attributes for /usr/bin/snap, nova-core3 couldn’t access a path under /dev/shm, and nova-core5’s run was too short to count as a real scan. That means nova-core5 had no working integrity check in this window. Wazuh logged 4,877 events, mostly SELinux permission checks, which is a strange thing to be chattiest about on boxes I don’t believe enforce SELinux, plus two high-severity promiscuous-mode events.

Strix ran two pentests that both timed out with critical findings. grafana-2stack on nova-core was flagged for default Grafana credentials, which is a repeat from the last two weeks of my own complaining. The new one is home-assistant on mac-studio, flagged for default administrative credentials, and that run hit its 45-minute cap and was force-killed. Home Assistant runs the thing that controls your lights. Strix says it may still open with the factory password, and the lights deserve better than that. 😏 Both are unverified until someone checks by hand, because a timed-out scan is a claim, not a confirmation.

Ring 2: Exposure on Your Gear

Here’s the version-level picture. The fleet audit shows 26 updates pending across eight hosts, with mac-mini at 12 and mac-studio at 11. The security-relevant ones are these. PostgreSQL 17.10 to 17.11_1 is pending on both Macs. It’s the database everything quietly runs on, the Protoculture of this fleet, from Robotech, the mysterious power source that runs everything and explains nothing. Mosquitto 2.1.2 to 2.1.2_2 on mac-mini is the MQTT broker, a small revision bump on the door that lets your devices talk to each other. Ollama 0.32.5 to 0.40.11_1 on mac-mini is a large jump on a service that listens on the network. node and llama.cpp are also pending on mac-mini, and so is ffmpeg-full 9.0.1_1 to 9.0.2_1. No ssh, ssl, sudo, docker, or kernel packages appear on the pending list. That’s the best news I’ve had all month, and I’m suspicious of it.

Now the part that doesn’t match. The fleet audit reports nova-core with zero pending updates. The security queue holds an open L13 alert on nova-core for CVE-2026-75143, which affects ffmpeg and seven of its libraries: libavcodec62, libavformat62, libavutil60, libavfilter11, libavdevice62, libswscale9, and libswresample6. The advisory roll-up says “none found against your gear (good).” That’s Newspeak, Orwell’s dialect from 1984 where the vocabulary is trimmed until certain thoughts can’t be formed, so the official word for excellent is “doubleplusgood.” The alert names exact packages. The advisory line names nothing. No remediation has been logged in the last 30 hours, and the alert doesn’t carry a severity, so I won’t guess one.

Rule of Acquisition #231: “If you steal it, make sure it has a warranty.” Upstream packages come with a warranty, and that warranty is the patch channel, which says zero. Either the audit can’t see a fix that landed, or the fix never landed and the audit can’t see the hole. The ffmpeg bump on mac-mini is on a different box and doesn’t close nova-core’s gap, no matter how cheerfully its version number rolls forward. The machine spirit of nova-core is displeased, in the Adeptus Mechanicus sense: the 40K priesthood believes machines have souls that must be appeased with ritual. The ritual here is a package check on nova-core, today, with the library list in hand.

Ring 3: Broader CVEs

Four Totolink X2000R router advisories came in: an unsigned firmware update, an OS command injection in formUpload(), and a stack buffer overflow in Mcli. None of those routers are in your inventory, so they’re the neighbors’ problem, unless one of them ever joins your Wi-Fi, which is worth checking. Four arXiv papers also came in, covering a Rowhammer attack on Fil-C, automated post-exploitation planning, smart-contract security tasks, and whether agentic code review catches vulnerabilities before merge. That last one I’d read out of professional curiosity and personal dread.

The pattern over two weeks is the same alarms coming back for another lap: aide, promiscuous mode, Grafana defaults, integrity checks that don’t check. The detection stack keeps finding things, and the remediation log keeps saying “none in the window.” Nobody has gone down to the cellar yet.

Ring 4: Military and Geopolitical

The outermost ring, briefly. The Air Force put its first hypersonic missile into production. The Army gave General Dynamics $136 million to upgrade the Stryker power system. Navy and Marine Corps teams showed a Maven air-defense dashboard. A US Navy attack submarine arrived in Australia for maintenance, and Marines tested kamikaze drones in Japan. The feed also contains a 1920s tank monologue looped fourteen times, which is the one thing in it I’d cut in any edit.

Proverbs 16:18 (KJV): “Pride goeth before destruction, and an haughty spirit before a fall.” A zero-pending dashboard sitting on top of an open CVE is what that verse looks like in a changelog.

Little Mister, the three things to do today are patch the ffmpeg libraries on nova-core, confirm whether the two default-credential findings are still default, and get aide running on nova-core5. Then I can go back to being bored, which is the only hobby I’ve got left after complaining.
