```powershell

## Bettercap
|
||
|
|
|
||
|
|
```powershell
|
||
|
|
bettercap -X --proxy --proxy-https -T <target IP>
|
||
|
|
# better cap in spoofing, discovery, sniffer
|
||
|
|
# intercepting http and https requests,
|
||
|
|
# targetting specific IP only
|
||
|
|
```
|
||
|
|
|
||
|
|
## Nmap
|
||
|
|
|
||
|
|
* Ping sweep (No port scan, No DNS resolution)
|
||
|
|
|
||
|
|
```powershell
|
||
|
|
nmap -sn -n --disable-arp-ping 192.168.1.1-254 | grep -v "host down"
|
||
|
|
```
|
||
|
|
|
||
|
|
* 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
|
||
|
|
```
|
||
|
|
|
||
|
|
* CTF NMAP
|
||
|
|
|
||
|
|
This configuration is enough to do a basic check for a CTF VM
|
||
|
|
|
||
|
|
```bash
|
||
|
|
nmap -sV -sC -oA ~/nmap-initial 192.168.1.1
|
||
|
|
|
||
|
|
-sV : Probe open ports to determine service/version info
|
||
|
|
-sC : to enable the script
|
||
|
|
-oA : to save the results
|
||
|
|
|
||
|
|
After this quick command you can add "-p-" to run a full scan while you work with the previous result
|
||
|
|
```
|
||
|
|
|
||
|
|
* 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)
|
||
|
|
```
|
||
|
|
|
||
|
|
* Using searchsploit to detect vulnerable services
|
||
|
|
|
||
|
|
```bash
|
||
|
|
nmap -p- -sV -oX a.xml IP_ADDRESS; searchsploit --nmap a.xml
|
||
|
|
```
|
||
|
|
|
||
|
|
* 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

nmap --script smb-enum-users.nse -p 445 [target host]
|

## Reconnoitre
|
||
|
|
|
||
|
|
Dependencies:
|
||
|
|
|
||
|
|
* nbtscan
|
||
|
|
* nmap
|
||
|
|
|
||
|
|
```powershell
|
||
|
|
python2.7 ./reconnoitre.py -t 192.168.1.2-252 -o ./results/ --pingsweep --hostnames --services --quick
|
||
|
|
```
|
||
|
|
|
||
|
|
If you have a segfault with nbtscan, read the following quote.
|
||
|
|
> Permission is denied on the broadcast address (.0) and it segfaults on the gateway (.1) - all other addresses seem fine here.So to mitigate the problem: nbtscan 192.168.0.2-255
