New Flock Safety WiFi Findings — "Flock Camera net." SSID + 5GHz Hotspot + Locally Administered MACs

Summary

Passive WiFi wardriving via WiGLE (Samsung SM-G990U2, WiGLE app v2.108, Android 14) captured a confirmed Flock Safety ALPR camera hotspot with three findings not currently documented in flock-you or the broader research community.


Finding 1 — New SSID Pattern: "Flock Camera net."

The known Flock hotspot SSID is Flock-XXXXXX. This camera was broadcasting Flock Camera net. — a completely different naming format.

This matters because jakeswiz searched WiGLE using Flock-* as the pattern and found zero results in his metro. A camera broadcasting Flock Camera net. would be completely invisible to that search. Any SSID-based detection logic that only matches the Flock- prefix will miss this variant.

Suggest adding Flock Camera as an additional SSID match pattern alongside the existing Flock- prefix.


Finding 2 — 5GHz Hotspot Confirmed on Channel 157

The camera was broadcasting its hotspot simultaneously on:

  • 2.4GHz channel 1 (2412 MHz)
  • 5GHz channel 157 (5785 MHz)

Using sequential MACs on each band — xx:xx:xx:9f:a2:de on 2.4GHz and xx:xx:xx:9f:a2:df on 5GHz — consistent with a dual-band WiFi module assigning adjacent MACs to each radio.

NSM-Barii's flock-back already documented a Flock probe request on 5GHz channel 149. This adds a second data point — a hotspot beacon on 5GHz channel 157 — confirming 5GHz operation across at least two different devices and two different channels.

Strongest signal readings:

  • 2.4GHz: -46 dBm
  • 5GHz: -59 dBm

Finding 3 — Locally Administered MACs on Hotspot Interface

The MAC prefix on both captured addresses has the locally administered bit set (bit 1 of first byte = 1). These are not IEEE-registered OUIs — they are intentionally assigned outside the standard OUI registry.

The sequential last bytes (:de and :df) rule out random MAC generation. This appears to be deliberately assigned locally administered addressing.

The standard flock-you pre-filter correctly skips locally administered MACs to eliminate MAC-randomizing phones. But this means that when a Flock camera has its hotspot active using locally administered MACs, it gets filtered out by that same logic — invisible to OUI-based WiFi detection when the hotspot is broadcasting.

This suggests Flock may be deliberately using locally administered MAC space for hotspot interfaces as an anti-fingerprinting measure. SSID pattern matching remains effective regardless of MAC addressing scheme.

Open question: is this consistent across Flock deployments or specific to this firmware version?

60+ total readings across approximately 5 minutes of highway driving past the camera location. Camera already logged on DeFlock at approximately 28.493, -81.458.
