In this list I made more than 10K wordlist for admin finding path , and more than 800 subdomain for possible admin panel .
All possible Admin panel directory and subdomain lists
Use Any Fuzzing Tool like Dirbuster , Gobuster , FFuF etc ..
//** replace with the target.site.com with your target website // // this FUZZ will replace with the each wordlist character // // -mc 200 will check the status code 200 **//
ffuf -u "https://www.target-site.com/FUZZ" -w admin-directory.txt -mc 200
ffuf -u "https://FUZZ.target-site.com" -w admin-subdomain-list.txt -mc 200
