  2. 2. Overview ● ● ● ● ● ● ● ● Nikto - short introduction, Burp Suite, Wikto, Nmap, Metasploit, Nessus, OpenVAS, Useful links.
  3. 3. Nikto - short introduction ● You manage several Web servers/applications ● Need to find potential problems and security vulnerabilities, including: - Server and software misconfigurations - Default files and programs - Insecure files and programs - Outdated servers and programs
  4. 4. Nikto - short introduction ● ● ● ● ● ● ● ● Web server scanner, Created by : David Lodge and Chris Sullo, Version 1.00 Beta released on: December 27, 2001 Current version: 2.1.5, Written in: Perl, The name is taken from the movie: The Day The Earth Stood Still, Sponsored by: Sunera LLC, Official page :
  5. 5. Nikto - short introduction ● ● Open source, Performs test against web servers for multiple items: - Looks for over 6500 potentially dangerous files/CGIs, - Checks for outdated versions of over 1250 servers, - Looks for version specific problems on over 270 servers, - Attempts to identify installed web servers and software, - Checks for the presence of multiple index files and HTTP server options, ● Output can be saved in a variety of formats: text, XML, HTML.

  7. 7. Burp Suite ● ● ● Integrated platform for performing security testing of web applications, Its tools work great togheter to support the entire testing process, from initial mapping and analysis of an application’s attack surface, through to finding and exploiting security vulnerabilities, Gives full control , meaning combine advanced manual techniques with state-of-the-art automation for fast, effective results.
  8. 8. Burp Suite - key components ● ● ● ● ● ● ● Proxy - an intercepting proxy , which lets you inspect and modify traffic between your browser and the target application, Spider - an application aware spider, for crawling content and functionality, Scanner - an advanced web application scanner, for automating the detection of numerous types of vulnerabilities, Intruder - an intruder tool, for performing powerful customized attacks to find and exploit unusual vulnerabilities, Repeater - a repeater tool, for manipulating and resending individual requests, Sequencer - a sequencer tool, for testing the randomness of session tokens, Ability to: save your work and resume your work later, write plugins.
  9. 9. Burp Suite - Nikto Proxy - can intercept the http requests and show them in proper format so it can be used to analyse the queries made by Nikto and discover vulnerabilities.

  11. 11. Wikto ● ● ● ● ● ● ● ● Roles: checks for vulnerabilities in webservers,also in the implementation, it tries to find interesting directories and files on the web site and it looks for simple scripts that can be abused, Written in: .NET C#, Version: Release date: 2008-12-14, Created by: sensepost, Cost: free, License:GPL, Nikto for Windows with extra features: fuzzy logic eror code checking, a back-end miner, Google assisted directory mining, real time HTTP request/response monitoring.
  12. 12. Wikto - Nikto Wikto uses Nikto’s database to perform different checks against web server. Nikto DB
  13. 13. Nmap ● ● ● ● ● ● ● ● ● ● Network Mapper, Roles: network discovery and security analysis, Technique: uses IP raw packets , Determine: what host are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running and other, Free and Open Source, Available with: command line and GUI viewer( Zenmap), Well documented and supported, Portable: runs on al major operating systems, Won numerous awards and was featured in twelve movies , Official site:
  14. 14. Nmap -Nikto Scenario: Nikto supports scanning multiple hosts via text file of host names or IPs. A host file may also be a Nmap output in “greppable” format. Operating system Windows 7, 64 bit Steps ● ● ● ● Nikto Version 2.1.5 Download and install Nikto and Nmap, Put in the Environment Variables, Path for the two folders of the programs mentioned above, In Start search for cmd, wait to open Command Prompt, Type the following for localhost, port 80: nmap -p80 localhost/24 -sT -Pn -oG - | -h - Nmap -oG - greppable format, name of the file - , to be passed through stdin/stdout to Nikto, command-line zip file: -sT - TCP connect scan, -Pn - no ping , disable host discovery.

  19. 19. Nessus -Nikto ● ● ● ● ● ● ● ● ● ● ● Started: as a project in 1998, by: Renaud Deraison, to: provide a free remote security scanner, but: in 2005 Tenable Network Security take it and: make it closed source. Can perform scans on: networks, operating systems, web applications,mobile devices, Most popular and capable scanner, for UNIX systems particularly, Support for different operating systems, Has an extensive plugin database, updated daily, (plugin = vulnerability test written in NASL(Nessus Attack Scripting Language) ) Various formats of the scan results : plain text, XML, HTML and Latex, Last stable release: 5.2.1/May 7, 2013.
  20. 20. Nessus -Nikto Nikto can be integrated in Nessus Settings: How: when Nessus finds a web server,automatically launch Nikto. 1. 2. 3. 4. 5. Nikto installation, Put in PATH, Ensure that nikto.nasl is present in the Nessus install(Nasl Wrapper), Run “nessusd -R”, Finally restart nessusd.
  21. 21. OpenVAS -Nikto ● ● ● ● ● ● ● Open Vulnerability Assessment System, Began under the name GNessUs, as a fork of the Nessus open source tool, Framework of several services and tools, Roles: vulnerability scanning and vulnerability management solution, Cost: free, Developed by: Greenbone Networks , Last stable release: 6.0/April 17, 2013. Nikto ● ● ● is integrated, as a tool, into OpenVAS, the OpenVAS plugin for Nikto integration(nikto.nasl) needs to be present and enabled, the results of a Nikto scan are included in OpenVAS final scan.
