Subdomain Enumeration

Dec 29, 2023

Using subfinder.

subfinder -d hltv.org -all -cs | tee  domains.txt

Cleaning up urls

cat domains.txt | cut -d "," -f 1 | tee domains.txt

Getting hosts of the domain

 cat domains.txt | xargs -I{} host {} | tee -a host.txt

Using HTTPX

cat domains.txt | httpx -wc -sc -cl -ct -asn -web-server -o httpxout.txt -p 8000,8080,8443,443,8008,3000,5000,9090,900,7070,9200,15672,9000 -threads 75 -location

Using ASN, you can go to ipinfo and get all the ip ranges.

And then later, go to shodan and search that ip range

Net:10.200.11.0/24
asn:ASN

Reverse who is

crt.sh
Crt.sh/?O=Paypal,%20inc.&output=json

Finding ASN’s

amass intel -asn ASN | tee -a asn.txt

Using tlsx
We can give a range of ip addr, it will give us the domains that are there on that

echo 173.0.84.0/24 |tlsx -san -cn -silent
