Penetration Testing Framework for System/Network Administrators – Pythem

Introduction

Pythem is a penetration testing tool to find out the vulnerabilities. In this tool, we have different types of tools and modules in one place (packet investigation, reverse engineering, network analytics, forensics application). Most of the system/network administrators can use this tool for testing their own devices to ensure their environment is safe. Pythem tool is completely built on python language.

  • Now, use this command to launch the tool  pythem
Pythem – Tool Launch
  • Now, type command help to find all the options.

  • In pythem tool, we have four different sections. In each section we have different tools
  • Section 1
    • Network, Man in the middle attack and Dos
  • Section 2
    • Exploit Developments and Reverse Engineering
  • Section 3
    • Brute-Force
  • Section 4
    • Utils

ARPSpoofing

What is ARP Spoofing Attack?

ARP is called as (Address Resolution Protocol). The main aim of using an arp spoofing attack by simply flooding an arp request to LAN (Local Area Network). So every victim request to the server, will travel from hacker’s machine.

  • Use this command arpspoof help to find the options.
  • Now, set the interface, target IP, Gateway and start scanning to initialize ARP spoofing
Pythem – ARP Spoofing
  • Here, we successfully initialized ARP Spoofing
  • Now, use this command sniff to capture the packets or monitor the network traffic.
Pythem – ARP Traffic
  • Yes, we are successfully able to monitor victim’s activities.

Shellcode Encoding and Decoding

Shellcode is used to compromise the victim’s machine based on a vulnerability in the local network, intranet on a remote network, a hacker can take control of the victim’s machine, if the shellcode is executed.

Pythem – Shellcode En/Decoder
  • Successfully encoded and decoded the shellcode

Brute Force Attack

What is Brute Force Attack?

Brute Force Attack is a password cracking technique using a wordlist. This tool will enter many passwords like numerical, alphabets and special characters. It takes much to crack the password.

  • Use this command brute help to find the options.
  • In the brute force, the attack has a different type of technique
    • ssh
    • form
    • url
    • hash
  • Choose any technique from above four
  • Next, use this command to find the help options
    • Brute <enter the technique > help
  • Before starting the attack we have to generate a wordlist with the name of wordlist.txt. You can generate your own wordlist with crunch, as detailed in this link.
  • Here, we have used DVWA as a target, then set the wordlist file and start the attack.
  • The type the input name, password and enter the username to brute-force.
  • It will start entering the passwords, which are mentioned in the wordlist.
Pythem – Brute Force Attack
  • Successfully we found the password using the brute force attack. We can see in the above picture.

Cookiedecode

  • In this section we have an option cookiedecode. This will decode to base64 format
pythem>  cookiedecode
[+] Enter the cookie value:  d3d3LmlpY3liZXJzZWN1cml0eS5jb20=

Conclusion

As we saw different type of attacks at one framework. This tool is easy to use and understand, in less time with better results.
