What is a Penetration Testing?

Penetration Testing

“The process of evaluating systems, applications, and protocols with the intent of identifying vulnerabilities usually from the perspective of an unprivileged or anonymous user to determine potential real world impacts…”

In short ...

Penetration Testing

…trying to break into stuffbefore the bad guys do

PenTest Methodologies

PenTest Methodologies

Reconnaissance

Purpose:Narrow down to Specific Target

and Technique

Visiting Organisation Website Consulting Public Internet Registry Google Hacking Using Tools: Nikto ,Nessus,dig, nslookup and lot more ..

Scanning

Purpose:Look for Live Host , Firewall

Service Running ,Version running

Types of Scan: TCP connect Scan SYN Scan UDP Scan

Tools: Nmap,Nessus ,tracert and lot more

Exploitation

Purpose:To exploit the vulnerability and to deploy payload on the remote

system

Tools: Metasploit,Wireshark,Cain,Aircrack-ng, Etherape,

Maintaining Access

Network Mapping

Why to Map network??• Mapping Networks gives a better

understanding of underlying Internet and network infrastructure.

• Network mapping makes testing ,evaluating security of network easy and efficient.

• File Size : 2.94 GB

• Blue print of entire site

• Has credentials of phpMyAdmin,Joomla CMS

• It is the server end code of the site

UoA Hacking Incident




Right Now !! The Site is hosted on my machine



Login into The Admin Pannel



Log in Successful!! – Can create and delete post



Total No of Admin the Site has



Logging Into phpMyAdmin: SQL Server



Logged in successfully



Can view and manipulate the Professors Records



Records of All student studing at UoA

Live Demonstration

Man in the Middle Attack:Such type of attack are very easy to launch.

In this type of attack the ,the attacker poisons the ARP Table(Address Resolution Protocol)

Hence, can divert all the traffic through its System and can also alter the packets ,if he wishes..

Tools:Etherape,Driftnet

Live Demonstration Man in the Middle Attack

***Caution****

1.The attack may or may not be successful

2.It may show some objectionable content

Simple Network Scanner in C#

This simple network scanner scans the given work group/domain for computers in Directory Services

The Developed Network Scanner take the limit of I P addresses as Input and scans the entire domain and outputs the Computer Name.

It uses the following Namespaces:

using System.Net;using System.Net.Dns;

Methods: Dns.GetHostByAddress();


Algorithm:

private void button1_Click(object sender, EventArgs e) { String ipAdress = textBox1.Text; string machineName = string.Empty; try { IPHostEntry hostEntry=Dns.GetHostEntry(ipAdress);

machineName=hostEntry.HostName; } catch (Exception ex) { textBox2.Text = "Machine Not Found"; } textBox2.Text= machineName;
