massdns : DNS brute-force. It's very fast however it's prone to false positives.

sed 's/$/.domain.com/' subdomains.txt > bf-subdomains.txt
./massdns -r resolvers.txt -w /tmp/results.txt bf-subdomains.txt
grep -E "tesla.com. [0-9]+ IN A .+" /tmp/results.txt

gobuster : 1 resolver/layer

gobuster dns -d mysite.com -t 50 -w subdomains.txt

shuffledns : wrapper around `massdns`

shuffledns -d example.com -list example-subdomains.txt -r resolvers.txt

puredns : It also uses `massdns`.

puredns bruteforce all.txt domain.com

aiodnsbrute : uses asyncio to brute force domain names asynchronously.

aiodnsbrute -r resolvers -w wordlist.txt -vv -t 1024 domain.com

Second Round DNS Brute-Force

dnsgen : Given the domains and subdomains generate permutations.

cat subdomains.txt | dnsgen -

CORS Brute Force

Sometimes you will find pages that only return the header Access-Control-Allow-Origin when a valid domain/subdomain is set in the Origin header. In these scenarios, you can abuse this behaviour to discover new subdomains.

ffuf -w subdomains-top1million-5000.txt -u http://10.10.10.208 -H 'Origin: http://FUZZ.crossfit.htb' -mr "Access-Control-Allow-Origin" -ignore-body
