Network Encryption Findings

I collected a bunch of readings into the database and ran this query:

SELECT encryption, count(DISTINCT mac) FROM iwscan_readings GROUP BY encryption;

which yielded:

encryption off - 65 Networks

encryption wep - 4 Networks

encryption wpa - 12 Networks

encryption wpa2 - 597 Networks

Further investigation of the unencrypted networks yielded an interesting result. Many are Eero Mesh network devices. According to Reddit users, the Eero mesh sets up an "unencrypted" hidden network but it's encrypted by the nodes using AES.
