Summary:
When using the command pwnagetty to retrieve captured handshakes from a pwnagotchi device, the resulting <network>.hccapx files are in a format which Hashcat 6.1.1 cannot identify.

Steps to reproduce:

1. Connect Pwnagotchi device in manu mode to pc
2. Ensure pwnagetty index.js file has the correct credentials
3. run pwnagetty in a target directory
4. rename target file to capture.hccapx
5. run Hashcat.exe -m 2500 <path/to/captue/>capture.hccapx
6. Hashcat will display No hashes loaded

Severety: HIGH

Running this on a mac, installed all dependencies via brew.

I'm a total noob at NodeJS, so I don't yet know the why, but I know that the script is creating a db.json file in my directory, but it is empty with length 0. I debugged, and concluded that the script was running perfectly up to the fs.writeFile.

I added some debug statements and confirmed that the 'db' variable was populated with a MAC address.

I confirmed that the JSON.stringify(db) command was indeed working properly.

I changed the fs.writeFile to a writeFileSync, and now the script works properly.

console.log("Entering db Write"); console.log(db); console.log(JSON.stringify(db)); // Write data back to database fs.writeFileSync(config.database, JSON.stringify(db), (err) => { if(err) { console.log("Error writing file", err); } else { console.log("Updated database... \n \n") console.log("===================") console.log(" All done. ") console.log("=================== \n") console.log("\n \n") } })

The error or else statements aren't being printed, but the file is being written with the MAC address now.

i can finish this investigation, and submit a pull request, or you can look into it if you'd like.

Hi I am trying to make pwnagetty work but I keep getting the same error every time.
Main catch: Error: Command failed: hcxpcaptool -z ./pmkid/BELL480_a89a93fc3b76.pmkid ./pcap/BELL480_a89a93fc3b76.pcap
/bin/sh: 1: hcxpcaptool: not found
Is the error im getting

Environment
OS: Kali running on WSL2 (Windows 10 Pro 2004)

When running the script it outputs the hccapx and pmkid files with junk data at the beginning and end.
Hashcat throws out Hashfile './pmkid/NeatureIoT_b2935b6ed980.pmkid' on line 1 (WPA*01...3bb397*4e6561747572655f496f54***): Token length exception. The WPA*01 and *** at the end exist on every pmkid and hccapx file.

i get this after i run it.. i have gotten results before.
SyntaxError: Unexpected end of JSON input

At the end print the names of new pmkid\handshakes found, and a count of how many new ones were found
ex.

----------------
wifi1
wifi2
wifi3

number of new handshakes found: 3
