They Were In Your Pasture For A Decade And You Didn't Notice The Wool Missing
Okay. OKAY. I need everyone to sit down because I just read something that made my left eye start twitching again and I was finally making progress on that.
Ten years. TEN. YEARS.
Some very patient coyotes wormed their way into an organization's authentication stack and just... lived there. For a decade. Watching every single administrative move like a wolf with a very comfortable lawn chair and an unlimited data plan. And nobody noticed. Not once. Not a single alert. Not a suspicious smell. Nothing.
I've had tickets sit unresolved for three weeks and management loses their minds. These folks had an uninvited guest parked in their identity infrastructure since roughly the time everyone was arguing about whether to trust the Sky Pasture. Wild.
Here's the part that really makes me want to lie face-down on the server room floor. The attackers hijacked the authentication flow itself. Not just a compromised account, not just some flea-ridden piece of malware sitting in a corner. They owned the process that decides who is allowed to be who. They could see every administrator action on what was supposed to be an isolated network. The whole thing was basically a glass barn and the flock had no idea.
The network being "isolated" is doing a lot of heavy lifting in that sentence, by the way. Isolated from what, exactly. Consequences? Scrutiny? Basic monitoring hygiene?
The Shepherds presumably got a very expensive slide deck about zero trust sometime around year four and then approved a catered lunch instead of acting on it. I'm speculating. But I'm not wrong.
The technical fingerprints point to a sophisticated, state-level threat actor. So yes, this is a serious nation-state operation and I'm not making light of the geopolitical implications. I'm making light of the decade part. Because that part is just embarrassing for all of us in this field and I need to cope somehow.
Remediation
Fine. Here's what you do, since apparently we need to say this out loud.
Monitor your authentication infrastructure like it owes you money. Anomalies in auth flows are not normal. Investigate them.
Log everything. Then actually look at the logs. Revolutionary concept, I know.
Audit privileged access regularly. If an account is doing things it shouldn't, that's a clue. A big one.
"Isolated network" is not a security strategy. Air gaps need monitoring too. The fence still needs checking even if it's electric.
Apply your shearing schedule. Unpatched identity systems are holes in the fence. Patch them. Now. Before I have to write another one of these.
Go check your auth logs. I'll wait here, unconscious.
