## Enumerate all subdomains (only if the scope is *.domain.ext)
|
||
|
||
### Using Subbrute
|
||
|
||
```bash
|
||
git clone https://github.com/TheRook/subbrute
|
||
python subbrute.py domain.example.com
|
||
```
|
||
|
||
### Using KnockPy with Daniel Miessler’s SecLists for subdomain "/Discover/DNS"
|
||
|
||
```bash
|
||
git clone https://github.com/guelfoweb/knock
|
||
git clone https://github.com/danielmiessler/SecLists.git
|
||
knockpy domain.com -w subdomains-top1mil-110000.txt
|
||
```
|
||
|
||
Using EyeWitness and Nmap scans from the KnockPy and enumall scans
|
||
|
||
```bash
|
||
git clone https://github.com/ChrisTruncer/EyeWitness.git
|
||
./setup/setup.sh
|
||
./EyeWitness.py -f filename -t optionaltimeout --open (Optional)
|
||
./EyeWitness -f urls.txt --web
|
||
./EyeWitness -x urls.xml -t 8 --headless
|
||
./EyeWitness -f rdp.txt --rdp
|
||
```
|
||
|
||
### Using Google Dorks and Google Transparency Report
|
||
|
||
You need to include subdomains ;)
|
||
https://www.google.com/transparencyreport/https/ct/?hl=en-US#domain=[DOMAIN]g&incl_exp=true&incl_sub=true
|
||
|
||
```bash
|
||
site:*.domain.com -www
|
||
site:domain.com filetype:pdf
|
||
site:domain.com inurl:'&'
|
||
site:domain.com inurl:login,register,upload,logout,redirect,redir,goto,admin
|
||
site:domain.com ext:php,asp,aspx,jsp,jspa,txt,swf
|
||
site:*.*.domain.com
|
||
```
|
||
|
||
### Using Sublist3r
|
||
|
||
```bash
|
||
To enumerate subdomains of specific domain and show the results in realtime:
|
||
python sublist3r.py -v -d example.com
|
||
|
||
To enumerate subdomains and enable the bruteforce module:
|
||
python sublist3r.py -b -d example.com
|
||
|
||
To enumerate subdomains and use specific engines such Google, Yahoo and Virustotal engines
|
||
python sublist3r.py -e google,yahoo,virustotal -d example.com
|
||
|
||
python sublist3r.py -b -d example.com
|
||
```
|
||
|
||
### Using Subfinder
|
||
|
||
```powershell
|
||
go get github.com/subfinder/subfinder
|
||
./Subfinder/subfinder --set-config PassivetotalUsername='USERNAME',PassivetotalKey='KEY'
|
||
./Subfinder/subfinder --set-config RiddlerEmail="EMAIL",RiddlerPassword="PASSWORD"
|
||
./Subfinder/subfinder --set-config CensysUsername="USERNAME",CensysSecret="SECRET"
|
||
./Subfinder/subfinder --set-config SecurityTrailsKey='KEY'
|
||
./Subfinder/subfinder -d example.com -o /tmp/results_subfinder.txt
|
||
```
|
||
|
||
### Using Findomain
|
||
|
||
```powershell
|
||
$ wget https://github.com/Edu4rdSHL/findomain/releases/latest/download/findomain-linux
|
||
$ chmod +x findomain-linux
|
||
$ findomain_spyse_token="YourAccessToken"
|
||
$ findomain_virustotal_token="YourAccessToken"
|
||
$ findomain_fb_token="YourAccessToken"
|
||
$ ./findomain-linux -t example.com -o
|
||
```
|
||
|
||
### Using Aquatone - old version (Ruby)
|
||
|
||
```powershell
|
||
gem install aquatone
|
||
|
||
Discover subdomains : results in ~/aquatone/example.com/hosts.txt
|
||
aquatone-discover --domain example.com
|
||
aquatone-discover --domain example.com --threads 25
|
||
aquatone-discover --domain example.com --sleep 5 --jitter 30
|
||
aquatone-discover --set-key shodan o1hyw8pv59vSVjrZU3Qaz6ZQqgM91ihQ
|
||
|
||
Active scans : results in ~/aquatone/example.com/urls.txt
|
||
aquatone-scan --domain example.com
|
||
aquatone-scan --domain example.com --ports 80,443,3000,8080
|
||
aquatone-scan --domain example.com --ports large
|
||
aquatone-scan --domain example.com --threads 25
|
||
|
||
Final results
|
||
aquatone-gather --domain example.com
|
||
```
|
||
|
||
Alternatively, you can use the [Docker image](https://hub.docker.com/r/txt3rob/aquatone-docker/) provided by txt3rob.
|
||
|
||
```powershell
|
||
https://hub.docker.com/r/txt3rob/aquatone-docker/
|
||
docker pull txt3rob/aquatone-docker
|
||
docker run -it txt3rob/aquatone-docker aq example.com
|
||
```
|
||
|
||
### Using Aquatone - new version (Go)
|
||
|
||
```powershell
|
||
# Subfinder version
|
||
./Subfinder/subfinder -d $1 -r 8.8.8.8,1.1.1.1 -nW -o /tmp/subresult$1
|
||
cat /tmp/subresult$1 | ./Aquatone/aquatone -ports large -out /tmp/aquatone$1
|
||
|
||
# Amass version
|
||
./Amass/amass -active -brute -o /tmp/hosts.txt -d $1
|
||
cat /tmp/hosts.txt | ./Aquatone/aquatone -ports large -out /tmp/aquatone$1
|
||
```
|
||
|
||
### Using AltDNS
|
||
|
||
It's recommended to use massdns in order to resolve the result of `AltDNS`
|
||
|
||
```powershell
|
||
WORDLIST_PERMUTATION="./Altdns/words.txt"
|
||
python2.7 ./Altdns/altdns.py -i /tmp/inputdomains.txt -o /tmp/out.txt -w $WORDLIST_PERMUTATION
|
||
```
|
||
|
||
Alternatively you can use [goaltdns](https://github.com/subfinder/goaltdns)
|
||
|
||
### Using MassDNS
|
||
|
||
```powershell
|
||
DNS_RESOLVERS="./resolvers.txt"
|
||
cat /tmp/results_subfinder.txt | massdns -r $DNS_RESOLVERS -t A -o S -w /tmp/results_subfinder_resolved.txt
|
||
```
|
||
|
||
### Using Nmap
|
||
|
||
```powershell
|
||
nmap -sn --script hostmap-crtsh host_to_scan.tld
|
||
```
|
||
|
||
## Subdomain take over
|
||
|
||
Check [Can I take over xyz](https://github.com/EdOverflow/can-i-take-over-xyz) by EdOverflow for a list of services and how to claim (sub)domains with dangling DNS records.
|
||
|
||
### Using tko-subs
|
||
|
||
```powershell
|
||
go get github.com/anshumanbh/tko-subs
|
||
./bin/tko-subs -domains=./lists/domains_tkos.txt -data=./lists/providers-data.csv
|
||
```
|
||
|
||
### Using HostileSubBruteForcer
|
||
|
||
```bash
|
||
git clone https://github.com/nahamsec/HostileSubBruteforcer
|
||
chmod +x sub_brute.rb
|
||
./sub_brute.rb
|
||
```
|
||
|
||
### Using SubOver
|
||
|
||
```powershell
|
||
go get github.com/Ice3man543/SubOver
|
||
./SubOver -l subdomains.txt
|
||
```
