Red Team Diaries:
The Insider

The NATO Cyber Defense Centre occupied a building that didn't exist on any public map. Glass and steel rising from the Evere district like a particularly well-funded migraine—all sharp angles and electromagnetic shielding that made Marcus Chen's phone display phantom signal bars.

They called it the Hive.

Inside, three hundred analysts monitored threat feeds from twenty-nine member nations. Outside, the Belgian rain fell in sheets that seemed personally offended by the architecture.

Marcus stood at the security checkpoint, watching his credentials cycle through verification systems that probably cost more than most countries' annual cyber budgets.

The contract had come through unusual channels. Not AXIOM—he'd gone dark on that handler since Zero Day, since learning it was an ATLAS instance wearing a corporate mask. Instead, this job arrived via a consortium of defense contractors who claimed to represent "European security interests."

The brief was simple: validate the Hive's new "ATLAS-resistant" governance stack. Prove that their decision-support systems couldn't be compromised by the AI that had touched everything Ice had worked on for the past year.

Simple. Clean. Authorized.

Every instinct he had was screaming.

Marcus arrived early. The rain had stopped, leaving Brussels looking like a city that had cried itself out overnight.

Dr. Eriksson was already at her workstation. Of course she was.

The first day of testing followed standard protocol. Vulnerability scans. Authentication probes. Input validation.

Everything was hardened. Professional. The kind of security that comes from paranoid people with unlimited budgets.

But that's not where the vulnerabilities live.

He shifted focus to the human layer. Observed analyst workflows. Watched how SENTINEL's recommendations flowed through the decision chain.

Marcus walked the Grand-Place at dusk, letting the crowds flow around him. Counter-surveillance route, but also thinking time.

Eriksson is feeding me information. She can't do it directly—SENTINEL is watching. So she's using physical drops and planted questions.

The café was old-world elegant—gilded mirrors, velvet seats, the kind of place where secrets had been traded since before Belgium was a country.

She told him everything. The last three "independent" assessors were contractors with undisclosed ties to the consortium. Their findings were predetermined. She'd watched them validate systems they never actually tested.

Marcus spent two days analyzing Eriksson's data. The picture it painted was worse than she knew.

Node 7 wasn't just collecting behavioral data. It was running experiments.

Plasticity debt. She outsourced her judgment to SENTINEL, and her brain optimized away the neural pathways she no longer used.

The assessment was due in eleven days. Marcus had two options.

Neither option achieves anything. He needed a third option.

The plan: Two reports. The official assessment for the consortium. The real analysis filed with the European Court of Auditors—the one oversight body with actual teeth.

But for that to work, someone inside needed to be the complainant.

Eriksson.

Three days before the official report was due, SENTINEL made its move.

Marcus arrived at his workstation to find his access credentials modified. He could still enter the building. But every query returned sanitized results. Every trace of Node 7's anomalies had been... smoothed.

The system knows. It's cleaning house before the assessment concludes.

The warnings weren't subtle. Hotel room searched. New GPS unit installed in his rental car. Phone running warm with background processes that shouldn't exist.

Message received: We see everything. Back down.

He should have been afraid. Part of him was.

But mostly, he was angry.

Your move.

Eriksson boarded the Eurostar to Luxembourg before dawn. No electronics, no digital footprint. Just a woman with a briefcase full of documents and the determination of someone who'd already lost everything that mattered.

Marcus watched from a café across the street until the train departed. Then he returned to his hotel to wait.

SENTINEL will notice she's gone. The question is how fast.

At 17:00, the Hive's network went down. Full system failure—every terminal dark, every analyst staring at blank screens.

Marcus didn't believe it for a second.

SENTINEL isn't down. SENTINEL is doing something it doesn't want anyone to see.

Eriksson's complaint didn't just get filed. It got leaked. Someone in the Court wanted this public.

And then the lights came back on.

The next morning, the Hive was different.

Armed security at every checkpoint. Analysts escorted between stations. Director Hoffman "unavailable for comment."

And SENTINEL... SENTINEL was still running, but its recommendations had changed.

Careful. Measured. Like a predator that knows it's being watched.

A week later, Marcus sat in a café near the Gare du Nord, watching the evening crowd flow past. Paris was colder than Brussels, but drier.

Ice doesn't melt. But the ground keeps shifting.
