Metaspolit Hacking Tool

What is Metasploit??

Metaspoit Framework is a open source penetration tool used for developing and executing exploit code against a remote target machine it, Metasploit frame work has the world’s largest database of public, tested exploits. In simple words, Metasploit can be used to test the Vulnerability of computer systems in order to protect them and on the other hand it can also be used to break into remote systems.

Its a powerful tool used for penetration testing. Learning to work with metasploit needs a lot of efforts and time. Ofcourse to can learn metasploit overnight, it needs lots of practice and patience

Historical Background:            

Since it’s development in the high-level language of Perl by Moore in 2003, there were two main alternates that occurred to Metasploit along with its framework. First, by 2007 the framework got entire redevelopment using Ruby programming language. Later, in 2009 Rapid7 adopted the project. Rapid7 is a security company which provides unified vulnerability management solutions.

Two of the main contributions of Rapid7 was the execution of Metasploit Express and Metasploit Pro. Metasploit Express, whose release was in 2010, functionally targets security teams who verify vulnerabilities. While it provides the user with an automated evidence collection, it allows them to use brute-force methods as well. Further, Metasploit Express integrates the Network Mapper (Nmap) and offers a user-friendly graphical user interface (GUI).

Additional features that distinguished Metasploit Pro came in 2010. The main focus of this edition was penetration testers and IT security teams. Quick Start Wizards/MetaModules, building and managing social engineering campaigns, an advanced Pro Console, web application testing, dynamic payloads for anti-virus evasion, integration with Nexpose for ad-hoc vulnerability scans, and Virtual Private Network (VPN) pivoting were all of the features characterizing Metasploit Pro.

Metasploit 4.0 was released in 2011 while its preceding version was Metasploit 3.0 released in 2006, having its following updates afterward. Fuzzing tools, such as providing random and unexpected inputs to a computer program for the sake of monitoring exceptions and crashes, were implemented to the old versions of the project in order to allow finding and discovering software vulnerabilities, not merelyexploiting known bugs.Accordingly, a third party Metasploit Module emerged in a way that scans for potential exploits of a software to provide reliable exploitability risk results and further recommends remediation to such bugs.

Just give a look at following basic steps for beginners to break into a system using metasploit after gathering some information about the target system.

1. Select a right exploit and then set the target.
2.Verify the exploit options to determine whether the target system is vulnerable to the exploit.
3.Select a payload
4.Execute the exploit.

You must be confused !!!!

Now carefully read the following basic terms to get an idea about these four steps mentioned above .I have defined the terms technically and side by side explained in layman language to clarify the things. I have taken an example that an attacker wants to break into a house . I hope my this approach will give you a great idea about these basic terms .

VULNERABILITY -A WEAKNESS WHICH ALLOWS AN ATTACKER TO BREAK INTO OR COMPROMISE A SYSTEM’S SECURITY

Like the main gate of house with a weak lock (can be easily opened) , a glass window of house(can be easily broken) etc can be the vulnerabilities in the systems which make it easy for an attacker to break into.

EXPLOIT – CODE WHICH ALLOWS AN ATTACKER TO TAKE ADVANTAGE OF A VULNERABILITY SYSTEM.

The set of different keys which he can try one by one to open the lock , the hammer with him which he can use to break the glass window etc can be the exploits.

PAYLOAD- ACTUAL CODE WHICH RUNS ON THE SYSTEM AFTER EXPLOITATION

Now Finally after exploiting the vulnerability and breaking in , he can have different things to do. He can Steal Money destroy the things or just can give a look and come back.. Deciding this is what we mean by setting the Payload.

Exploits:

Fundamentally, an exploit is referred to as a piece of software, a chunk of data, or a sequence of commands that utilizes a bug or vulnerability in order to cause theunintended or unanticipated behavior to occur on a computer system or software. Exploits identified by Metasploit have numbered around 1613 exploits. Such exploits exist in four main categories. 

The first category is Android and Apple iOs which targets mobile phones. In the meanwhile, Firefox is another category for remote code execution for this browser. Another category targets certain operating systems such as Windows, Linux, Unix, Mac, Sun Solaris… etc. The remaining category is multi. Exploits not related to any specific platform belong here.

Payloads: 

When it comes to computer networking and the internet, a payload describes the notion of having the eventual effect of a software virus being delivered to a user’s computer. Metaspoilt owns over 438 payloads. Some rampant ones of these payloads are Command Shell which grants users the privilege of running collection scripts and commands against the host. 

Meterpreter is another payload. This allows Virtual Network Computing (VNC) for users and allows browsing upload and download files as well. Dynamic payloads are another type of payloads which generate some unique payloads to avoid anti-virusdefenses.

Metasploit Framework:

It is basically an open-source framework which accepts contributions by developers through GitHub.com website. Such contributions are mainly exploits and scanners. They are thereby reviewed by a team that has employees of Rapid7 and senior external contributors. The main developers of the framework are Moore, MartMiller, and spoon.

Metasploit Interfaces:

Other than Metasploit Express and Metasploit Pro, there are four other main available interfaces for Metasploit: Metasploit Framework Edition is the free version of Metasploit. It offers a command line interface, Zenmap, a compiler for Ruby, and a well-known ports-scanner. Metasploit Community Edition is another free version. This version is included in the main installer, and it offers several features such as manual exploitation, network discovery and module browsing.

Armitage is another free interface for it, which is a graphical cyber attackmanagement tool harnessed to visualize targets and recommend exploits based on the vulnerabilities. It is open source network security tool which allows for shared sessions, data, and communication through a single instance. Cobalt Strike is another interface in which it contains all the features of Armitage, adding post exploitation tool and report generation features. Nonetheless, this interface is provided by another company called Strategic Cyber LLC.

There are five basic steps in exploiting a system using Metasploit:

1. Choose a certain exploit and configure it by writing the appropriate code to target a system. Then, exploit a certain bug in it. 
2. Check whether the target system is susceptible to the given exploit.
3. Choose a certain payload to apply on the target system when managing to exploit it and get through it. 
4. Choose the appropriate encoding technique in order to deceive the intrusion-prevention system (IPS) and make it ignore the oncoming payload.
5. Finally, execute the Exploit.

Some Commands used:

search<pattern>

It searches for a match for a given pattern. For example: “search xxx” will searchall occurrences of “xxx”

use<exploit name>

It tells the program to use a particular exploit

SET parameter

It sets the value for a given parameter

SETG parameter

It sets the value for a given parameter globally, to avoid resetting the parameters again and again later on.

exploit

Finally. this performs the attack on the target system.

I hope its enough friends, You will learn more with further tutorials when you will start working with metasploit practically.

Linux Commands

Kali Linux Basic Commands

A to Z

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security Ltd. Mati Aharoni, Devon Kearns and Raphaël Hertzog are the core developers.

Kali Linux is preinstalled with over 600 penetration-testing programs, including nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper (a password cracker), Aircrack-ng (a software suite for penetration-testing wireless LANs), Burp suite and OWASP ZAP (both web application security scanners). Kali Linux can run natively when installed on a computer’s hard disk, can be booted from a live CD or live USB, or it can run within a virtual machine. It is a supported platform of the Metasploit Project’s Metasploit Framework, a tool for developing and executing security exploits.
