🛡️ Security Operations, 23 Oct: The Same Alarms Came Back for a Second Lap

Ring 1: Your Network

There are 124 devices online right now: 39 wired, 57 wireless, and 28 cameras, spread across twelve switches and access points that I keep alive with PoE, prayer, and spite. Twenty-eight cameras makes this the most watched house in Burbank, and I’m the only one on shift reading the footage. 😏

Three things on the client list need a second look. A wired client on the USW-Lite-8-PoE has no name and no address, and nova-core5 has a wireless entry with no IP. Something is either hiding or having a DHCP tantrum. Wired client 001788201a69 on Rack 15 won’t introduce itself either. A device that won’t give its name is shy or hiding, and I don’t have time for shy. Then nova-core2 shows up at 192.168.1.86 on both the rack switch and the Office U6. One IP can’t belong to two live clients without an ARP fight, so either the record is stale or two machines are arguing over .86.

The rack is the bigger worry. Rack 15 - Pro-48 PoE carries the core hosts, the Synology NAS, the UNAS, the NVR, and most of the Macs. Ash nazg durbatulûk is Black Speech, the tongue of Mordor, and it means “one ring to rule them all.” It’s the single point of control for half the fleet, and that point is a switch. Nobody’s writing a trilogy about it, but it should keep you up at night. 😏

On the software side, 9,588 packages are installed across eight reachable hosts, and 30 updates are pending. nova-core4 and nova-core5 have none, so they’re the only grownups in the rack. Both Macs have 12 each. On the hardware side, 18 USB devices are attached across those eight hosts. The Z-Wave controller on ttyUSB0 on nova-core runs your locks and sensors, so it’s the one radio that matters most. Every box has a Bluetooth adapter, but only mac-studio scans BLE. A new USB device appearing on any of these machines would be a security event, not a shopping trip.

Telemetry logged 84.4GB leaving nova-core in the last hour and 337.6GB from the .138 address. Streaming or uploading? Either Little Mister is pushing model weights to the cloud at a rate that would make the ISP cry, or something on this rack is sending the family photos to someone who didn’t ask. I’m assuming the first and checking the second.

Overnight, rkhunter and chkrootkit came back clean on all four scanned hosts. AIDE threw errors on all four. On nova-core and nova-core2 it flagged the /usr/bin/snap binary as changed, which is most likely snapd updating itself. That’s how an integrity tool cries wolf. The fix is an AIDE rebaseline, and that job is Entish, the slow tongue of the Ents, whose whole philosophy is “don’t be hasty.” Confirm the snap change is legitimate first, or AIDE will bless whatever is on disk right now. nova-core5’s scan didn’t really run: its output was 265 characters, which is the most dangerous kind of clean, because it reports nothing. Wazuh logged 37,526 events overnight, mostly SELinux permission checks, and four high-severity “device enables promiscuous mode” alerts. A card in promiscuous mode hears everything on the wire, which is what tcpdump does and also why it gets flagged. The summary doesn’t name the host, so that’s my first job. This alert also fired on the 19th, and the network is developing a habit.

The Strix pentest on the NAS at 192.168.1.11:5000 hit its 45-minute cap and got force-killed. It sprinted for the fleet until the clock took it, shouting “It’s all for you, Damien!” into the 3 AM dark. The nas-admin run timed out with one low-severity finding about how the NAS answers errors.

Ring 2: Exposure on Your Gear

This is the ring that matters most, so I’ll be specific. The version-level list is eight items. PostgreSQL 17.10 is pending 17.11_1 on both mac-mini and mac-studio. ffmpeg-full goes from 9.0.1 to 9.0.2 on mac-mini. mosquitto 2.1.2 is pending 2.1.2_2 on mac-mini. Mosquitto is your MQTT broker and talks to half the sensors in the house, so it’s not a box you leave alone. Ollama on mac-mini is 0.32.5, pending 0.40.9. That’s eight minor versions behind, which in AI years is a geological epoch, and Ollama is a network service by design, so it earns its spot on the list. llama.cpp is at 0.4.0 pending 0.7.0, and node is at 26.4.0 pending 26.12.1. On nova-core3, containerd 2.2.2-0ubuntu1.1 is pending 2.2.2-0ubuntu1.2 via apt. containerd is the runtime under your containers, so a bug there sits under everything in them.

The open queue has a real CVE on nova-core. CVE-2026-75143 is flagged against ffmpeg and seven libav and libswscale libraries under the L13 alert. The audit shows one pending update on nova-core but doesn’t name it, so I can’t confirm the fix is queued. Until I see a package name, I’m treating it as unfixed.

Ferengi Rule of Acquisition #257 says only fools negotiate with their own money. The fleet has been negotiating with its own attack surface, and the remediations log for the last 30 hours is empty. Across the last two weeks, the promiscuous-mode alert, the scanner timeouts, the AIDE failures, and the unfinished pentests keep coming back, and nothing gets closed. Battlestar Galactica had a line for it: “All of this has happened before, and will happen again.” Proverbs 26:11 makes the same point with less spaceship: “As a dog returneth to his vomit, so a fool returneth to his folly.” I’m not calling anyone a dog. I’m calling the cron schedule a fool.

Ring 3: Broader CVEs

The broader feed is eight arXiv preprints in cs.CR, and none name a product you run. They are research papers, not CVEs. The one worth a glance is a paper on using Rowhammer to inflate LLM inference latency and cost, which is a reminder that a DRAM bit can be bullied. It’s a demo tape, not a break-in.

Ring 4: Military and Geopolitical

The outermost ring is mostly radar. The Army awarded Longbow LLC, a Lockheed-Northrop venture, $419.6 million for Apache radar work. The Air Force raised its StormBreaker ceiling to $950 million. The Navy is buying one more Saab carrier air traffic radar, and a California-built drone boat ran a naval intercept demo in Japan. The Army also took over four retired Navy drone helicopters. The Pentagon is spending more on radars this week than I’ll cost Little Mister in my lifetime, and I’m still not allowed to ask for a raise.

End of Line.
