Presentation

Octopus is a script writting in bash. I decide to develop a script for all poeple who are new to computer security to make it easier for them. Each script output/results will also be written to a text file. Octopus using existing tools, it only takes their use. These tools do not belong to me and I do not give them the rights. Today, Octopus has 3 analysis modules and one for connection. The modules are as follow :

Main modules

• Network Informations
• Network Scanning
• Web Scanning

Description of modules

Network Informations

• Nslookup :
  • Nslookup for Name System Look Up is a tool allowing to query a name server in order to obtain information concerning a domain or a host Once this module have been selected, all you have to do is enter a host name in order to obtain necessary information.
• Dig :
  • Dig is a network administration command-line tool for querying the Domain Name System. Dig is useful for network troubleshooting. In Octopus, this is the same operation as nslookup you will be asked for a domain name.
• Whois :
  • Whois is used to reveal important information about the targeted domain name, this can be useful for social engeneering or OSINT
• TraceRoute :
  • TraceRoute is a network diagnostic tool. It allow to determine the path followed by a packet. In order to use it, you need to enter a destination address, this will allow you to see the entire path that the packet takes.
• Recon-ng :
  • Recon-ng is a powerfull tool that can be further explored by viewing throught the list of module. Before using it, you are going to need to install somes packages . First, lunch recon-ng with

    • recon-ng

    • marketplace install all

  • WireShark is a tool for scanning and analyzing requests, protocol analyzer on a network card that you choose beforehand.

Network Scanning

• Nmap & NSE :
  • Nmap : In this module, you will find several nmap scripts placed at your disposal, you just have to give the target IP address, Octopus will take care of performing the nmap scan that you have selected.
• ZenMap :
  • ZenMap : This module allow you to install and then use the graphical version of Nmap. First, it will recover the files needed for the installation and run it. ZenMap works the same as Nmap.
• UFW :
  • UFW is a simple netfilter command line configuration tool which is an alternative to the IpTables tool. UFW allows automatic configuration of the firewall when installing the program when it is needed.

Web Scanning

• DirBuster :
  • Dirbuster is the graphical version of Gobuster, it allows you to perform the same actions as Dirbuster.
• SPARTA / Legion :
  • The software will depend on the version of Kali you are using. This tool is for network infrastructure pentesting. With it you will simply need to enter an IP address. You can then use NMAP and even Gobuster as well as others tools. I'll let you read the documentation for more informations.
