Fuzz Faster U Fool (FFUF)

FFUF FUZZER TOOL

FUZZ = Tells program where to fuzz

#-u = URL

-w = wordlist

We can fuzz parameters to check for SQLi, XSS, etc.

Example:

ffuf -u http://IP_ADDRESS/file.php?id=FUZZ

ffuf -u http://IP_ADDRESS/file.php?FUZZ=1'

--mc = Match code

--fc = Filter code

-c = color output

-fs NUM = File Size

Subdomain enumeration example:

ffuf -u http://example.com -c -w /path/to/wordlist.txt -H 'Host: FUZZ.example.com' -fs 0

-x PROXY:PORT = Sends all ffuf traffic through a web proxy (Burpsuite, network pivoting)

TIP: We can even use regex to search for files
