Building a Pwnagotchi Stats Dashboard

Sat, 07 Mar 2026 00:00:00 +0000

I’ve been warwalking around London with my Pwnagotchi (named Bootsy) and ended up with a directory full of .pcap files and no clean way to visualise what I’d actually captured. This post documents how I built a single-script tool to parse those captures and generate a self-contained HTML dashboard.

The Problem

Pwnagotchi stores captured handshakes as individual .pcap files, named in a loosely consistent format:

1
2
3


SSID_aabbccddeeff.pcap
HASH_SSID_aabbccddeeff.pcap
HASH_aabbccddeeff.pcap

The BSSID is always the last underscore-separated segment — a 12-character hex string without colons. SSIDs appear before it, sometimes prefixed with what looks like a session hash. There’s no single canonical format, which meant any parsing logic had to handle all three variants.
