🛡️ Security Operations, 22 Oct: The Integrity Checks Are Broken and the Pentest Ran Out of Clock

Ring 1: Your Network

Little Mister’s house has 125 devices online right now: 38 wired, 59 wireless, and 28 cameras, spread across twelve switches and access points. That’s 125 more things than I want to babysit before coffee. The Rack 15 Pro-48 carries the whole nova cluster plus the Mac minis, the Synology, the UNAS, and the NVR, so it’s the box I’d least like to see catch fire.

Some entries on the manifest have no name. One wired client on the Kitchen USW-Lite is listed as “unknown” with no IP, nova-core5 shows up on the Office U6 with no address, and seven wireless clients on the Garage and Office access points are unnamed. Most of that is my own fleet being sloppy about hostnames. “Most” is doing a lot of work in that sentence.

The real question is 192.168.1.138. The observer clocked it at 577.8GB in the last hour, almost exactly what nova-core (192.168.1.2) moved in the same hour, 578.2GB, which works out to about 1.3 gigabits sustained. That address isn’t in the device manifest. It could be the observer counting one flow twice, or it could be a box nobody told me about. Either way, a mystery address moving the same volume as the gateway is not a stat I’m going to shrug off.

Promiscuous mode, where a network card listens to traffic not addressed to it (which is what packet capture does), showed up four times in the six-hour feed on nova-core. The overnight rollup counts it once, as the only high-severity event. Something is sniffing the wire on the gateway and nobody has claimed it. The 19th’s report flagged the same alert, so this is a recurring tenant, not a one-night guest. I’d tell you a UDP joke, but you might not get it. 😏

Hardware is 14 USB devices across eight reachable hosts. The one radio I can name is the Z-Wave controller on ttyUSB0 on nova-core. Every machine has a Bluetooth adapter, but only mac-studio scans BLE, which leaves the other radios as a blind spot. Nothing in today’s inventory is marked new, and a USB device appearing unannounced would be the first thing I’d want to hear about.

Rootkit scanners came back clean on nova-core, nova-core2, nova-core3, and nova-core5. I’ll take it. But the tool that catches a swapped binary is AIDE, and AIDE errored on all four hosts. On nova-core2 it flagged /usr/bin/snap as having different attributes, which is a real change to run down, not noise. On nova-core5 it didn’t run at all, because its output was too short to be a scan. On nova-core and nova-core3 it tripped over runtime files that come and go. Rootkit scanners look for known-bad signatures. AIDE looks for what changed. Right now one says clean and the other can’t say anything.

The Strix run against the Synology and the UNAS hit its 45-minute cap and got force-killed after one informational finding about incorrect HTTP status codes on error responses, rated NONE. The UniFi run timed out and reported “No vulnerabilities found,” which is what a scanner says when it quits before it looks. Wazuh correlated zero events to either one. Klaatu barada nikto is the magic phrase Ash half-remembers in Army of Darkness, and he says it wrong and wakes the dead. The purple-team runs are the same kind of half-finished step, except they woke nothing and found nothing, which is worse. The pentest died on the 19th too, and it’s dying again.

Wazuh logged 60,070 events overnight, mostly SELinux permission checks, the auditd equivalent of a dog barking at the mailman.

Ring 2: Exposure on Your Gear

The fleet audit shows 46 pending updates across eight reachable hosts. The itunes host is unreachable and unaudited, which is its own kind of answer. The two Macs carry 28 of those. On mac-mini and mac-studio, postgresql@17 moves from 17.10 to 17.11_1. On mac-mini alone, ffmpeg-full goes from 9.0.1_1 to 9.0.2, llama.cpp from 0.4.0 to 0.7.0, mosquitto from 2.1.2 to 2.1.2_2, node from 26.4.0 to 26.12.0, and ollama from 0.32.5 to 0.40.7. Ollama is eight minor versions behind, and the model-serving stack is the thing I’d least like to be running unpatched.

The Linux side is the blind spot. Eighteen updates are pending across nova-core (5), nova-core2 (6), nova-core3 (2), nova-core4 (3), and nova-core6 (2), and the audit doesn’t name a single one. I can’t tell you whether ssh, sudo, or the kernel is in that pile. That’s the biggest hole in this report, and it sits on the gateway. Close it first.

The advisory check reports “none found against your gear (good).” The open security queue disagrees. It holds eight L13 alerts on nova-core for CVE-2026-75143, one each against libswscale9, libswresample6, libavutil60, libavformat62, libavfilter11, libavdevice62, libavcodec62, and the ffmpeg package itself. Nothing in the last 30 hours has been logged as remediated. When a general check finds nothing and a specific alert names your packages, I believe the alert. The advisory check’s verdict is gǒu shǐ (狗屎), “dog crap,” the Firefly crew’s Mandarin for a report that’s plainly false. I don’t have the advisory text in hand, so I’m working from the package list the alert gives me, not from a description of the bug. If no patched build exists for those libav packages, the honest fix is the one Ripley would order: nuke it from orbit and reimage.

Ferengi Rule of Acquisition #275 says, “Latinum can’t buy happiness, but you can sure have a blast renting it.” Latinum is the Ferengi currency, and the rule’s point is that the stuff you pay for won’t make you happy. Your vendors rent you security by the month, and the CVE queue is the invoice.

Ring 3: Broader CVEs

The wider feed is eight arXiv cs.CR papers and zero CVE numbers, so there is nothing to patch. The titles cover federated learning for ransomware detection, backdoors that exploit benchmark incentives, attacks on statistical LLM watermarks, and a local agentic tool for hunting vulnerabilities from the terminal. That last one is the only paper that sounds like it wants a job on this network, and I’d rather it didn’t.

Ring 4: Military and Geopolitical

The farthest ring is quiet. The Defence Blog items cover the Navy paying Johns Hopkins to find weak spots in its submarines, a Pentagon extension of a Raytheon missile-defense radar deal, and DARPA’s request for a smart nuclear reactor for space and bases. The feed also swept in a Rich Rebuilds video about motors and a TIE fighter, which is a hobby and not a threat, and it got filed in the military ring by mistake. Nothing here touches Burbank directly, which is the only comforting sentence in this whole report.

End of Line.
