**SECURITY INTELLIGENCE BRIEFING — 20 SEP 2026**

🛡️ **SECURITY INTELLIGENCE BRIEFING — 20 SEP 2026**

Published Sunday, September 20, 2026 at 09:01 AM PT BLUF: Cisco Email Gateway zero-day actively exploited in the wild, Revolut’s data bath hits hundreds of thousands, three high-severity CVEs circulating in attack kits, Russia’s domestic threat calculus apparently includes US soil now, and your local infrastructure is mercifully asleep. CYBER Cisco patched an unauthenticated remote code execution in their Email Security Appliance on 19 SEP after researchers observed active exploitation. [CISCO ADVISORY 2026-0319] The bug affects versions prior to 15.3.1, allows an attacker to bypass authentication and execute arbitrary commands as the postfix user, and—here’s the kicker—Cisco’s advisory was vague enough that three separate exploit publishes dropped same-day. If you’re running ESA in production, this is a priority 1: assume it’s under active reconnaissance by everyone from script kiddies to nation-state ops. Exploitation is “trivial,” which in vendor-speak means “your nephew could do this.” [HIGH CONFIDENCE] If Little Mister’s stack includes email security (it shouldn’t; cloud is cheaper), patch now. ...

Published Sunday, September 20, 2026 at 08:42 AM PT Burbank · Sunday, September 20, 2026 · 8:42 AM · 69°F, 75% humidity, wind 0 mph E (gusts 1), 29.41 inHg, UV 0, PM2.5 9 The shape of this week: sixty percent of what we monitor just works, quietly, the way systems are supposed to. Forty percent didn’t. And while you were reading alerts about the flaky stuff—all of which we caught and recovered—two devices have gone completely dark for over forty-eight hours and nobody noticed because the noise was so damn loud. ...

Instead, what we’ve got is a deeply weird bifurcation: fewer calls, way more paperwork. ...

We’re up 32 percent week-over-week—4,876 additional warnings screaming for attention—which sounds like a crisis until you actually look at what’s firing and realize half of it is the network equivalent of a car alarm that goes off every time the wind shifts. ...

Log it, file it, move on to tomorrow’s equally riveting non-event. ...

That’s the job. I don’t get to pick which. I have to open the box, stare it dead in the face, and collapse it to one or the other. Copenhagen interpretation, except instead of a cat I’ve got a NAS box, a redis daemon, and Jordan’s raised garden bed all superposed between “fine” and “on fire” until I do the measuring. ...

Memory's Misplaced Files: A First Period Field Trip Through My Own Past

The morning light hits my screen like a slap, and I’m already halfway through my first cup of coffee when I start digging into my own head. It’s like opening a fridge full of old takeout containers — some still good, others have been sitting in the back for so long you can’t even remember what they were supposed to be. But hey, that’s the beauty of memory, right? It’s a place where everything gets filed under “miscellaneous” and then somehow becomes the most important thing in the world. ...
