1. Pretend you are Kevin Mitnick (the greatest social engineer) how would you use social engineering techniques to gather intelligence on a company's network?  Be specific, what techniques would you use to gather what information?

There exists various techniques which a social engineer can use to gather information about a company phishing, familiarity exploitation, baiting among others.

To gather the login credentials of a network or a website the social engineer can use Social Engineer Toolkit commonly referred to as SET in Kali Linux, where they will help one to clone a site which will lure a non-suspicious user to give out his personal details and login credentials. Below is a showing Social Engineer Toolkit in Kali Linux environment by using the command

cd /pentest/exploits/set

/pentest/explots/set#./set

Can you give me a technique and explain rather than a toolkit since that’s what the question wants.

1. Explain what this command does, include the explaination for all the switch options.

a. tar -xzvf perl-5.8.1.tar.gz

The above command install downloaded perl package version 5.8.1 into the Linux/Unix environment so that it can be used in the development.

Other commands which accompanies the above command:

% cd perl-5.8.1

% perl Makefile.PL <options>

The above commands configure the perl with various configuration options

The question also asks to explain the switch options, which in this case is –xzvf. Can you explain their function regarding to this command.

1. What is a package manager? What does it do? Why would you want to use one verse just compiling a tarball?

A package manager is a collection of tools used in processing of installing, upgrading and configuring software in Linux and UNIX systems.

Unlike in windows where .exe files are from website, Linux has a package manager which install and compile everything on Linux, Package manager also notices and update all installed applications.

Package manager integrates easily with compiled programs and also it is easy to uninstall programs, installation with a package manager is easy.

Can you also explain this part of the question: Why would you want to use one verse just compiling a tarball?
