What is penetration testing ?

It’s the process to identify security vulnerabilities in an application by evaluating the system or network with various malicious techniques.

A penetration testing is a method of evaluating the security of a computer system.

Purpose of this test is to secure important data from outsiders like hackers who can have unauthorized access to system.

What is penetration testing ?

Once vulnerability is identified it is used to exploit system in order to gain access to sensitive information.

Causes of vulnerabilities:- Design and development errors- Poor system configuration- Human errors

Why conduct a penetration testing?

Financial data must be secured while transferring between different systems.

Many clients are asking for pen testing as part of the software release cycle.

Protecting your brand by avoiding loss of consumer confidence and business reputation.

To secure user data. To find security vulnerabilities in an

application.

What can be tested ?

Operating system, applications, database, networking equipments etc.

Dynamic websites, in-house applications etc.

Telephony (war-dialing, remote access etc.) Personnel (screening process, social

engineering etc.) Physical (access controls, dumpster diving

etc.) Wireless (wifi, Bluetooth, IR, GSM, RFID etc.)

What is metasploit ?

The Metasploit project is an open-source, computer security project which provides information about security vulnerabilities and aids in penetration testing and IDS signature development.

Metasploit is an framework which is used for the hacking of different kinds of applications,operating systems,web applications etc.

What is metasploit ?

Metasploit contain various exploits, payloads, modules etc.

Metasploit Framework is especially used by many of the hackers to generate payloads and attack the systems.

As Metasploit is an open source where any one can use it. This framework supports different operating systems like windows, linux ,mac os x etc.

Metasploit terms

Exploit used to take advantage of a security flaw within a system, network, or application.

Payload is code that our victim computer to execute by the Metasploit framework.

Module a small piece of code that can be added to the Metasploit framework to execute an attack.

Shell-code a small piece of code used as a payload.

What is a vulnerability?

A vulnerability is a security hole in a piece of software, hardware or operating system that provides a potential angle to attack the system.

A vulnerability can be as simple as weak passwords or as complex as buffer overflows or SQL injection vulnerabilities.

What is an exploit?

To take advantage of a vulnerability, you often need an exploit, a small and highly specialized computer program whose only reason of being is to take advantage of a specific vulnerability and to provide access to a computer system.

Exploits often deliver a payload to the target system to grant the attacker access to the system.

What is a payload?

A payload is the piece of software that lets you control a computer system after it’s been exploited.

The payload is typically attached to and delivered by the exploit.

Metasploit most popular payload is called Meterpreter, which enables you to do all sorts of funky stuff on the target system. For example, you can upload and download files from the system, take screenshots, and collect password hashes etc.

What is msfconsole ?

MSFconsole is an all-in-one interface to most of the features in Metasploit.

MSFconsole can be used to launch attacks, creating listeners, and much, much more.

Commands : Show exploits Show payloads Show options Use exploit

Commands

set payload Set LHOST Set RHOST Back Info Session▪ Session –l▪ Session –i 1

Meterpreter commands

Getuid -> show uid Ps -> show active process Migrate -> command used when hacker

want to migrate his process to any administrative privileges process.

Hashdump -> to dump password hash. Screenshot -> to take screenshot of victim. Shell -> to enter into the victim shell. download C:\\<file name> upload C:\\<file name>

More Meterpreter commands

keyscan_start -> start sniffing key strokes.

keyscan_dump keyscan_stop uictl disable keyboard uictl enable keyboard
