# Bug Hunting Methodology and Enumeration

## 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 Google Dorks
```bash
site:*.domain.com -www
site:http://domain.com filetype:pdf
site:http://domain.com inurl:&
site:http://domain.com inurl:login,register,upload,logout,redirect,redir,goto,admin
site:http://domain.com ext:php,asp,aspx,jsp,jspa,txt,swf
```

* Subdomain take over using HostileSubBruteForcer
```bash
git clone https://github.com/nahamsec/HostileSubBruteforcer
chmox +x sub_brute.rb
./sub_brute.rb
```

* 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
```

## Passive recon
* Using Shodan (https://www.shodan.io/) to detect similar app

* Using The Wayback Machine (https://archive.org/web/) to detect forgotten endpoints,
  ```
  look for JS files, old links
  ```

* Using The Harvester (https://github.com/laramies/theHarvester)
  ```
  python theHarvester.py -b all -d domain.com
  ```


## Active recon
* Basic NMAP
  ```bash
  sudo nmap -sSV -p- 192.168.0.1 -oA OUTPUTFILE -T4
  sudo nmap -sSV -oA OUTPUTFILE -T4 -iL INPUTFILE.csv

  • the flag -sSV defines the type of packet to send to the server and tells Nmap to try and determine any service on open ports
  • the -p- tells Nmap to check all 65,535 ports (by default it will only check the most popular 1,000)
  • 192.168.0.1 is the IP address to scan
  • -oA OUTPUTFILE tells Nmap to output the findings in its three major formats at once using the filename "OUTPUTFILE"
  • -iL INPUTFILE tells Nmap to use the provided file as inputs
  ```

* Aggressive NMAP
  ```bash
  nmap -A -T4 scanme.nmap.org
  • -A: Enable OS detection, version detection, script scanning, and traceroute
  • -T4: Defines the timing for the task (options are 0-5 and higher is faster)
  ```

* NMAP and add-ons
  1. Using searchsploit to detect vulnerable services
  ```bash
  nmap -p- -sV -oX a.xml IP_ADDRESS; searchsploit --nmap a.xml
  ```
  2. Generating nice scan report
  ```bash
  nmap -sV IP_ADDRESS -oX scan.xml && xsltproc scan.xml -o "`date +%m%d%y`_report.html"
  ```


* NMAP Scripts
  ```bash
  nmap -sC : equivalent to --script=default

  nmap --script 'http-enum' -v web.xxxx.com -p80 -oN http-enum.nmap
  PORT   STATE SERVICE
  80/tcp open  http
  | http-enum:
  |   /phpmyadmin/: phpMyAdmin
  |   /.git/HEAD: Git folder
  |   /css/: Potentially interesting directory w/ listing on 'apache/2.4.10 (debian)'
  |_  /image/: Potentially interesting directory w/ listing on 'apache/2.4.10 (debian)'

  nmap --script smb-enum-users.nse -p 445 [target host]
  Host script results:
  | smb-enum-users:
  |   METASPLOITABLE\backup (RID: 1068)
  |     Full name:   backup
  |     Flags:       Account disabled, Normal user account
  |   METASPLOITABLE\bin (RID: 1004)
  |     Full name:   bin
  |     Flags:       Account disabled, Normal user account
  |   METASPLOITABLE\msfadmin (RID: 3000)
  |     Full name:   msfadmin,,,
  |     Flags:       Normal user account

  List Nmap scripts : ls /usr/share/nmap/scripts/
  ```

* RPCClient
  ```bash
  ╰─$ rpcclient -U "" [target host]
  rpcclient $> querydominfo
  Domain:		WORKGROUP
  Server:		METASPLOITABLE
  Comment:	metasploitable server (Samba 3.0.20-Debian)
  Total Users:	35

  rpcclient $> enumdomusers
  user:[games] rid:[0x3f2]
  user:[nobody] rid:[0x1f5]
  user:[bind] rid:[0x4ba]
  ```
* Enum4all
  ```
  Usage: ./enum4linux.pl [options]ip
  -U        get userlist
  -M        get machine list*
  -S        get sharelist
  -P        get password policy information
  -G        get group and member list
  -d        be detailed, applies to -U and -S
  -u user   specify username to use (default “”)
  -p pass   specify password to use (default “”
  -a        Do all simple enumeration (-U -S -G -P -r -o -n -i).
  -o        Get OS information
  -i        Get printer information

  ```  

## List all the subdirectories and files

* Using BFAC (Backup File Artifacts Checker): An automated tool that checks for backup artifacts that may disclose the web-application's source code.
```bash
git clone https://github.com/mazen160/bfac

Check a single URL
bfac --url http://example.com/test.php --level 4

Check a list of URLs
bfac --list testing_list.txt
```

* Using DirBuster or GoBuster
```bash
./gobuster -u http://buffered.io/ -w words.txt -t 10
-u url
-w wordlist
-t threads

More subdomain :
./gobuster -m dns -w subdomains.txt -u google.com -i

gobuster -w wordlist -u URL -r -e
```

* 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 a script to detect all phpinfo.php files in a range of IPs (CIDR can be found with a whois)
```bash
#!/bin/bash
for ipa in 98.13{6..9}.{0..255}.{0..255}; do
wget -t 1 -T 3 http://${ipa}/phpinfo.php; done &
```

* Using a script to detect all .htpasswd files in a range of IPs
```bash
#!/bin/bash
for ipa in 98.13{6..9}.{0..255}.{0..255}; do
wget -t 1 -T 3 http://${ipa}/.htpasswd; done &
```

## Looking for Web vulnerabilities

* Look for private information in GitHub repos with GitRob
```
git clone https://github.com/michenriksen/gitrob.git
gitrob analyze johndoe --site=https://github.acme.com --endpoint=https://github.acme.com/api/v3 --access-tokens=token1,token2
```

* Explore the website with a proxy (ZAP/Burp Suite)
 1. Start proxy, visit the main target site and perform a Forced Browse to discover files and directories
 2. Map technologies used with Wappalyzer and Burp Suite (or ZAP) proxy
 3. Explore and understand available functionality, noting areas that correspond to vulnerability types
```bash
Burp Proxy configuration on port 8080 (in .bashrc):
alias set_proxy_burp='gsettings set org.gnome.system.proxy.http host "http://localhost";gsettings set org.gnome.system.proxy.http port 8080;gsettings set org.gnome.system.proxy mode "manual"'
alias set_proxy_normal='gsettings set org.gnome.system.proxy mode "none"'

then launch Burp with : java -jar burpsuite_free_v*.jar &
```
