How to Hack a Web Server - Shikshaglobe

Clients typically go to the web to get data and purchase items and administrations. Towards that end, most associations have websites. Most sites store significant data, for example, charge card numbers, email addresses and passwords, and so on. This has made them focus on aggressors. Destroyed sites can likewise be utilized to impart strict or political philosophies and so forth.


In this instructional exercise, we will present to you to web server hacking procedures and how you can safeguard servers from such assaults.


In this instructional exercise, you will learn:


Web server weaknesses

A web server is a program that stores records (generally pages) and makes them open by means of the organization or the web. A web server requires both equipment and programming. Aggressors as a rule focus on the endeavors in the product to acquire approved passage to the server. We should take a gander at a portion of the normal weaknesses that aggressors exploit.


Default settings-These settings, for example, default client id and passwords can be effectively speculated by the aggressors. Default settings could likewise permit playing out specific errands, for example, running orders on the server which can be taken advantage of.

Misconfiguration of working frameworks and organizations - certain designs, for example, permitting clients to execute orders on the server can be perilous in the event that the client doesn't have a decent secret key.

Bugs in the working framework and web servers-found bugs in the working framework or web server programming can likewise be taken advantage of to acquire unapproved admittance to the framework.

In extra to the previously mentioned web server weaknesses, the accompanying can likewise prompt unapproved access


Absence of safety strategy and methods absence of a security strategy and methodology, for example, refreshing antivirus programming, fixing the working framework, and web server programming can make security provisos for assailants.

Sorts of Web Servers

Coming up next is a rundown of the normal web servers


Apache-This is the regularly utilized web server on the web. It is cross-stage yet it's normally introduced on Linux. Most PHP sites are facilitated on Apache servers.

Web Information Services (IIS)- It is created by Microsoft. It runs on Windows and is the second most utilized web server on the web. Most asp and aspx sites are facilitated on IIS servers.

Apache Tomcat - Most Java server pages (JSP) sites are facilitated on this kind of web server.

Other web servers - These incorporate Novell's Web Server and IBM's Lotus Domino servers.

Sorts of Attacks against Web Servers

Catalog crossing assaults This kind of assault takes advantage of bugs in the webserver to acquire unapproved admittance to documents and organizers that are not in the public space. When the aggressor has gotten entrance, they can download touchy data, execute orders on the server or introduce noxious programming.


Forswearing of Service Attacks-With this kind of assault, the web server might crash or become inaccessible to the authentic clients.

Space Name System Hijacking - With this sort of assailant, the DNS setting is changed to highlight the aggressor's web server. All traffic that should be shipped off the web server is diverted to some unacceptable one.

Sniffing-Unencrypted information sent over the organization might be blocked and used to acquire unapproved admittance to the web server.

Phishing-With this kind of assault, the assault mimics the sites and guides traffic to the phony site. Clueless clients might be fooled into submitting touchy information, for example, login subtleties, Mastercard numbers, and so on.

Destruction With this sort of assault, the aggressor replaces the association's site with an alternate page that contains the programmer's name, and pictures and may incorporate ambient sound and messages.

Impacts of effective assaults

An association's standing can be demolished on the off chance that the assailant alters the site content and incorporates vindictive data or connections to a pornography site

Compromised client information might be utilized for fake exercises which might prompt business misfortune or claims from the clients who depended their subtleties with the association

Web server assault devices

A portion of the normal web server assault instruments incorporate;


Metasploit-this is an open-source apparatus for creating, testing, and utilizing exploit code. It tends to be utilized to find weaknesses in web servers and compose takes advantage of that can be utilized to think twice about the server.

MPack-this is a web double-dealing instrument. It was written in PHP and is supported by MySQL as the data set motor. When a web server has been compromised utilizing MPack, everything traffic to it is diverted to malignant download sites.

Zeus-this instrument can be utilized to transform a compromised PC into a bot or zombie. A bot is a compromised PC which is utilized to perform web-based assaults. A botnet is an assortment of compromised PCs. The botnet can then be utilized in a forswearing of administration assault or sending spam sends.

Weakness filtering frameworks incorporate devices, for example, Snort, NMap, Scanner Access Now Easy (SANE)

Firewalls can be utilized to stop basic DoS assaults by hindering all traffic coming from the distinguish source IP locations of the assailant.

Antivirus programming can be utilized to eliminate malevolent programming on the server

Handicapping Remote Administration

Hacking Activity: Hack a WebServer

In this pragmatic situation, we will take a gander at the life systems of a web server assault. We will accept we are focusing on www.techpanda.org. We are not really going to hack into it as this is unlawful. We will just involve the area for instructive purposes.


What we will require

An objective www.techpanda.org

Bing web search tool

SQL Injection Tools

PHP Shell, we will utilize dk shell http://sourceforge.net/projects/icfdkshell/

Data gathering

We should get the IP address of our objective and find different sites that share a similar IP address.


We will utilize an internet-based apparatus to find the objective's IP address and different sites sharing the IP address


Enter the URL https://www.yougetsignal.com/devices/sites on-web-server/in your internet browser

Enter www.techpanda.org as the objective
