Chapter 3: Linux Basic Command

Hello and welcome back to the course. today we discuss some Linux command that helps us to make our task easy. I make this course for beginners so if you already know how to use Linux you can skip this part. 

Linux Terminal Command

In all the Linux based system you can do all the work from this powerful terminal.

pwd

pwd

pwd stands for the present working directory it shows which directory you work at the time. it prints the full path of your working directory.

ls

lsls -la # show all the informationls /path to show filesls /home # show home directory files

ls stands for a long list. ls command shows how many files are listed in the directory. ls -la is a command that shows all the basic information of files. you can show permission and show all the hidden file in the folder.

mkdir

In this section, we make a directory and change the directory with cd.

mkdir demo     # make directory cd demo        # change directory cd /path       # you go diectly with currect path cd ..          # for one step back to the file path nano demo.txt  # make file

You can make one file that name demo.txt with the nano command. 

Write as you wish and after you have to write with ctrl+o and enter. 

cat

cat demo.txt

We show what is in the file with the cat command. You can copy the file into your device home file system with this command.

mv

mv demo.txt /home/device/Download  # move to Downloadmv demo.txt /home/device/jay.txt   #rename 

You can rename with the mv command. you can also move file with the same command.

You can show the file permission

chmod

chmod +x jay.txt--- --- ---o   g   e     o= file owner              g= group member
              e= for all 

r (read) = 4 w (write) = 2 x (execute) = 1 no permissions = 0# you can write as chmod 777 [file name] #give all the permissionchmod 600       #give permissionn to owner read and write else give                  nothing

We change permission using chmod command with options.

rm

rm -r jay.txtYou can remove any file in on any pathrm -r [path]

We can remove the file with the rm command.

man

man cp

The man command is amazing in Linux. the man command helps to how to use all command basically that guide how to use command.

Ethical Hacking Terminology 1.2 | Ethical Hacking From Scratch

Chapter 1.2: Ethical Hacking Terminology

First of all, I will introduce 

Types Of A Hacker

• White hat hacker
• Grey hat hacker
• Black hat hacker

White hat hacker 

A white-hat hacker is a good guy who finds a vulnerability on the system and reports to that particular organization for fixing them. in this course, we learn a thing as a white-hat hacker. it a fully legally process of hacking.

Grey hat hacker

A grey hat hacker is a border between a white hat or a black hat. grey hat hacker is always bordering between legal or illegal. 

Black hat hacker

Black hat hacker is defined as people is doing a thing without respect any law and permission of the owner. usually when people listen, hacker, they think a little bit about the black hat hackers.

Footprinting

Footprinting is a process you gain information about the server, server IP, what service running on the server, which port is open as well closed. 

DOS

Denial Of Service

Denial of service attack is leading to track down the server and make server or service unavailable for the user. 

For example, you have one ubuntu server that handles 10000 requests at a time. in the DOS attack, the attacker makes 10000+ request on the server from the software or any method. it a casual thing that your server is not handling this request and the server is crash for the actual user.

DDOS

Distributed Denial Of Service

Distributed Denial of Service is similarly to DOS but here the attacker is attacking too many machines and control as remote then attack the server. DDOS is more effective than DOS. 

FUD

Fully Undetectable 

In this field, it more effective than you exploit can not detect to the victim machine or they antivirus. there was you need to make a fully undetectable exploit or payload for the access of the victim machine.

RAT

Remote Administration Tool

It piece of code that create backdoor on the victim machine and gain access to the victim system. you can send them to the victim and one time execute. that file makes a backdoor for you into the victim machine. you can send whatever method like e-mail, USB or anything.

Root-Kit

A rootkit is to hide information from a running process on the system. when the victim is compromised you need to install a root-kit tool for maintaining access to the victim.

For example, you have to install an exploit on the victim system when the victim running the system taskbar they show the services that not show before in past. in this way you need to install some other exploit you retired request of the victim to tool kit and they respond, they are noting to running.  

Phishing

Phishing is one type of social engineering attack on the victim. in this attack, the victim is shown an email in the inbox. they click on the email link and they redirect to banking or any attacker site but they do not recognise this site is trusted or not and give some confidential credential to the site. 

This is not happening today. Today the attacker changes the victim DNS server to redirect the unconfirmed host and gain credential about the victim.

SQL Injections

SQL Injections is one of the most effective vulnerabilities on sites. SQL injections is a process to make SQL query on the server and they respond to some data that store on the server.

VPN 

A virtual private network is a term to hide on the internet. if you are connecting to the VPN every request of your system going through VPNs. VPN is secure but rather the VPN provider is not compromised your data.   

Proxies

Proxies are similar to the VPN but less secure. in this your network is a route to the internet and after your request will process. There are many free proxies is available on the market but they are very slow to use. Even you use paid proxies it chance that you make a footprint on the network and catch.

Tor

It an open source way to hide on the internet. Tor is faster than proxies. you can surf more reliable way with tor.

Introduction To Ethical Hacking 1 | Ethical Hacking From Scratch

Chapter 1: Introduction To Ethical Hacking 

What is Ethical Hacking?

Is it a very interesting thing that hacking with ethics? Ethical hacking is the good side of hacking that provide protection against bad guys. An ethical hacker is trying to exploit the system in many ways and report the company to fix that vulnerability and secure his system. 

Why Company Hire A Hacker?

every company want that they do not compromise system security, therefore they hirer hacker to exploit the system and find bug and vulnerability they can damage system in future. if the hacker finds a bug and exploits the system they pay for this. This amount pay across your exploitation weight. weight means how they affect the system security and compromise the data.

Course Overview 

In this course, I will teach you how to penetrate the system, exploit the system, break the system, compromise routers, etc. after you finish the course, you will be able to make serious damage in the real world. so that time I will make some clearance about it, it not legally that you can damage system that is not yours and without written permission of the owner, it illegally activity. I am strongly against that thing and everything that lead to against law. 

I recommend using this information for educational purposes only if you do some activity I am not responsible for. I hope you understand well. 

Some Information 

if you see the movies hacking seen. they go to the terminal and type some code or attack the system and boom! they get system access. this is totally the reverse of the real world.in the real world, it not possible. people are passing much sleepless night to exploit the system and access the system.
