Dead Drop Detector

Sometimes a signal shows up once and never comes back. That’s not noise. That’s a dead drop.

This tool scans a log of device appearances—Bluetooth, Wi-Fi, whatever—and flags anything that was only seen one time. Great for spotting burner phones, sneakernet beacons, or one-time drive-bys.

Feed it a text file with each line in the format:
timestamp | MAC address

It’ll churn through the mess and spit out just the ghosts.
