Internet is an amazing virtual world where you can "virtually" do anything: gambling, playing, watching movies,
shopping, working, “VoIPying”, spying other people and for sure auditing remote systems.
The security testers’ community has a large panel of security tools, methodologies and much more to perform
their pentests and audit assessments. But what happens if you find yourself weaponless.
No more Top 100 security tools, no more LiveCDs and no more exploitation frameworks. A security auditor
without toolbox is like a cop without gun.
Nevertheless, there is maybe a way to rescue yourself from this nightmare situation.
The magical solution could be Firefox and its extensions developed by ethical hackers and coders.
This article comes as an update for what we posted previously about how to switch your Firefox to more than an
usual simple browser. It was about application auditing
Here is an updated list of useful security auditing extensions:
Information gathering
● Whois and geo-location
o ShowIP : Show the IP address of the current page in the status bar. It also allows querying
custom services by IP (right mouse button) and Hostname (left mouse button), like whois,
netcraft.

enables the user with one-click to map and geo-locate any website they are currently
viewing.

data. Works with all versions of Firefox.
o Active Whois : Starting Active Whois to get details about any Web site owner and its host
server.
o Bibirmer Toolbar : An all-in-one extension. But auditors need to play with the toolbox. It
includes (WhoIs, DNS Report, Geolocation, Traceroute, Ping). Very useful for information
gathering phase
● Enumeration / fingerprinting

investigators, reporters, legal professionals, real estate agents, online researchers and
anyone interested in doing their own basic people searches and public record lookups as
well as background research.
● Googling and spidering
o Advanced dork : Gives quick access to Google’s Advanced Operators directly from the
context menu. This could be used to spider a site or scan for hidden files (this spider
technique is used via scroogle.org)
o SpiderZilla : Spiderzilla is an easy-to-use website mirror utility, based on Httrack from
www.httrack.com.
o View Dependencies : View Dependencies adds a tab to the "page info" window, in which it
lists all the files which were loaded to show the current page. (useful for a spidering
technique)
Security Assessment / Code auditing
● Editors
o JSView : The ’view page source’ menu item now opens files based on the behaviour you
choose in the jsview options. This allows you to open the source code of any web page in
a new tab or in an external editor.
o Cert Viewer Plus : Adds two options to the certificate viewer in Firefox or Thunderbird: an
X.509 certificate can either be displayed in PEM format (Base64/RFC 1421, opens in a new
window) or saved to a file (in PEM or DER format - and PKCS#7 provided that the
respective patch has been applied - cf.

live in any web page

httpOnly on the browser side
o Allcookies : Dumps ALL cookies (including session cookies) to Firefox standard cookies.txt
file
● Security auditing
o HackBar : This toolbar will help you in testing SQL injections, XSS holes and site security. It
is NOT a tool for executing standard exploits and it will NOT teach you how to hack a site.
Its main purpose is to help a developer do security audits on his code.
o Tamper Data : Use “tamper data” to view and modify HTTP/HTTPS headers and post
parameters.
o Chickenfoot : Chickenfoot is a Firefox extension that puts a programming environment in
the browser’s sidebar so you can write scripts to manipulate web pages and automate web

Proxy/web utilities

proxy configuration. It offers more features than SwitchProxy, ProxyButton, QuickProxy, xyzproxy,
ProxyTex, etc

server inside your browser. Use it to distribute files from your browser. It supports Server-side JS,
GET, POST, uploads, Cookies, SQLite and AJAX. It has security features to password-protect your

Malware scanner
● QArchive.org web files checker : Allowing people to check web files for any malware (viruses,
trojans, worms, adware, spyware and other unwanted things) inclusions.
● Dr.Web anti-virus link checker : This plugin allows you to check any file you are about to download,
any page you are about to visit
● ClamWin Antivirus Glue for Firefox : This extension scans every downloaded file automatically with
ClamWin.
Anti Spoof
● refspoof : Easy to pretend to origin from a site by overriding the URL referrer (in a http request). —
It incorporates this feature by using the pseudo-protocol spoof:// .. Thus it’s possible to store the
information in a "hyperlink" - that can be used in any context... like html pages or bookmarks
Besides, we keep watching new extensions and we are on the way to develop a new extension for Nmap and Nessus.
