Disclaimer: This investigation involved no hacking, intrusion, or unauthorized access. Everything described here is legal, passive measurement of signals and activity. My intention was simply to understand whether the Fiscalía Anti Corrupción in Querétaro behaves like a functioning office by analyzing its technical footprint.
What I Set Out to Measure
Any office with staff and computers produces a measurable presence:
- Wi‑Fi traffic from routers and laptops.
- Bluetooth beacons from phones and peripherals.
- Cellular activity from employees’ devices.
- Electromagnetic noise from monitors, servers, and power supplies.
If an office is active, you’ll see it in the spectrum. If it’s quiet, that silence itself is data.
My Setup
- Operating System: Kali Linux — chosen for its robust toolkit for wireless and spectrum analysis.
- Software Tools:
- gqrx — a spectrum analyzer for SDR devices, used to visualize signal activity across frequencies.
- aircrack‑ng — not for intrusion, but to detect the presence of Wi‑Fi networks and measure traffic density.
- Wireshark — configured only to confirm packet presence, not to capture or inspect content.
Hardware:
- Software‑Defined Radio (SDR) dongle with wideband antenna — allows scanning across a broad range of frequencies to detect signals.
- Portable EMF meter — measures electromagnetic radiation levels, useful for detecting whether multiple devices are powered and active.
- Directional antenna — focuses on the building to isolate its footprint from surrounding noise.
Procedure
- Establish baseline readings in a neutral location nearby.
- Move closer to the Anti‑Corruption office and log spectrum activity over several hours.
- Compare expected office activity (steady Wi‑Fi, bursts of cellular, background EMF from multiple devices) with actual readings.
The Results
The activity was far too low. For a building supposedly full of staff, computers, and investigations, the spectrum was quiet. Minimal Wi‑Fi traffic, almost no Bluetooth presence, cellular signals flat. The EMF meter barely moved.
That’s how I reached my conclusion: the building does not behave like a functioning office. The technical footprint doesn’t match the story.
Visual Confirmation
To cross‑check, I placed a pencam under some garbage opposite the building. On a Tuesday in May 2025, I recorded from 5 a.m. to 11 p.m. Nobody entered. Nobody left.
The Bigger Question
Meanwhile, corruption news is endless. Cries for help are countless. So why isn’t there any noise from Anti‑Corruption?
The dumbest explanation I’ve heard: “They strictly operate undercover, top secret.”
But corruption doesn’t happen in the shadows. It happens in broad daylight, in front of everyone’s eyes. And corruption, like vampires, doesn’t require secrecy. Expose it to light — and it dies.
