Ethical Hacking for Beginners (Chapter-7)

Networking Protocols and Models

Networking Protocols:- 

A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure, or design. 

List of network protocols:-

Transmission Control Protocol (TCP)

Internet Protocol (IP)

User Datagram Protocol (UDP)

Post office Protocol (POP)

Simple mail transport Protocol (SMTP)

File Transfer Protocol (FTP)

HyperText Transfer Protocol (HTTP)

HyperText Transfer Protocol Secure (HTTPS)

Telnet

Gopher

Some other non-popular protocols:-

ARP (Address Resolution Protocol)

DHCP (Dynamic Host Configuration Protocol)

IMAP4 (Internet Message Access Protocol)

SIP (Session Initiation Protocol)

RTP (Real-Time Transport Protocol)

RLP (Resource Location Protocol)

RAP (Route Access Protocol)

L2TP (Layer Two Tunnelling Protocol)

PPTP (Point To Point Tunnelling Protocol)

SNMP (Simple Network Management Protocol)

TFTP (Trivial File Transfer Protocol)

NAT:- Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.

The  NAT device accepts requests to traverse the internet from an internal machine. It then records that machine's IP address in a table and converts the IP address to the external IP address of the router. When the packet returns from its destination, the NAT device looks into its saved table of the original request and forwards the packet to the internal IP address of the system that made the original request within the LAN. And this process is so fast that one can’t even realize this whole conversion is happening on the back end.

OSI Model:-

The OSI Model consists of 7 layers. They are:-

Application Layer (Application Connected to the internet)

Presentation Layer (Standard data representation for application)

Session Layer (Manage session among applications)

Transport Layer (End to end error detection and correction)

Network Layer (Handle connection to the network by a higher layer)

Data Link Layer (provide safe communication of data over the physical network)

Physical layer (Define the physical characteristics of the network)

*Where First 3 are Software Layer and Last 3 are Hardware layer and the Middle one Transport Layer is the heart of OSI Model

We will dive deep into all of these layers in another chapter.

TCP/IP Model:-

TCP/IP model consists of 4 layers only. 

Application Layer (In this layer App and processes running on the network.)

Transport layer (Provides end to end data delivery service)

Internet Layer (Make datagram and handles data routines)

Network Layer (Provides routines allowing access to the physical network)

Will discuss all of these layers in detail in the future.

In the next chapter, we will discuss IP Addresses in detail.

Till then Happy Learning!

Networking Basics

What is Networking?

A network refers to two or more connected computers that can share resources such as data, a printer, an Internet connection, applications, or a combination of these resources.

Types of Network:- 

1. LAN (Local Area Network):- Mostly covers buildings or a set of closely related buildings

2. MAN (Metropolitan Area Network):- Covers a metropolitan area or a small geographic area such as a small town.

3. WAN (Wide Area Network):- Covers countries, or a large geographic area.

Open System:- A system that is connected to internet and ready to communicate is called open system

Closed System:- A system is not connected to the internet and can’t be communicated with.

Network topologies:- The arrangement of devices connected to a network. 

Some examples are:- Star, bus, Delta, ring, mesh, point to point, daisy chain, tree, hybrid etc.

image source:- Wikimedia commons

Network Components:- A network connection may have multiple other devices by which communication also occurs. Eg:- Router, switch, hub, bridge, wireless router, etc.

Unique identifiers of a network:-

Each device in a network is associated with some unique identifiers by using which a device can be identified.

1. Host Name:- Each device in the network is associated with a unique device name known as Hostname which you can get t know by typing “hostname” in the command prompt (without quotation) 

2. IP Address:- It is the logical address of a device connected to a network. It is a unique number assigned to every device connected to the internet. It has 2 versions IPv4 (32 bit long) and IPv6 (128 bit long). You can see it by typing “iconfig” in the command prompt for windows and “ifconfig” in Linux (without quote)

3. MAC Address:- This is the physical address. It is the unique identifier attached with each device NIC card (network interface card). It is 48 bit long. You can check it by using the same command “ipconfig/all”

4. Port:- Can be referred to as a logical channel using which data packets are transferred to any applications. It is a 16-bit long integer number and we have 216  ports available. Start from 0-65535 total 65536 ports. You can check by typing “netstat -a” by typing in the command prompt which ports are currently being used.

List of some important ports:-

20 FTP

21 FTP

22 SSH

23 Telnet

25 SMTP

53 DNS

69 TFTP

80 HTTP

88 Kerberos

110 POP3

123 NTP

135 Microsoft's RPC

137-139 Microsoft's NetBIOS

143 IMAP

161 SNMP

389 LDAP

443 HTTPS or HTTP over SSL

445 SMB

500 IKE

514 syslog

3389 RDP

 

5. Socket:- Combination of port and IP address is called socket.

In the next chapter, we will discuss some networking protocols.

In the upcoming chapters, we will discuss some basic networking 

concepts. Till then Happy Learning!.

Ethical Hacking For Beginners (Chapter-4)

 

Linux Commands(Part-1)

In Ethical Hacking Linux (Kali Linux) is being considered as the most used OS by attackers and cyber security professionals. And The biggest reason is:-

1. It is Open source (In most of the cases you don't have to spend money to buy this OS and most of its applications also you can get free updates as this is open-source. Bugs are being patched as soon as they are spotted because there is not a specific group of developers who work as Linux developers, everyone who has knowledge of Linux development can be developer and as soon as they find any bug they report it and fix it asap. So a wide range of people work here so finding an unpatched bug here is not easy here, and that's why it's considered the most secure/ safest OS as well.

2. Reason 2 is highly customizable, as it is open source it allows the user to see its source code and let them change as per their requirement. Also, most of its applications don’t want root-level permission. So, there is no such security concern here to install any unknown application. And most importantly it’s most of the applications are CLI-based, meaning it shows its user what's going on behind the screen. So the user can see it and if they find anything unusual they can act accordingly.

3. Another reason is its virus-proof. Now, virus-proof doesn't mean that it's not affected virus or Linux virus does not exist. It means It’s not affected by viruses, not as much as windows get. Because executable files do not exist for Linux(.exe) they treat exe as a text file(until you don’t use wine). So if someone tries to hide a payload in an exe and wait for the victim to double click it, in a Linux environment it will not gonna work out. In simple terms most of its application comes as package installer(.tar.gz) or Debian package(.deb). And user can easily check its permission and in most of the cases its install through the terminal(Similar to command prompt) so the user can track each and every step that what's going on behind the screen and if it needs root permission it also inform the user that it needs root permission, by default it does not takes root always We will deep dive into this later on the Linux chapter.

4. And the reason behind Linux virus-proof is Most of the Linux users are computer experts, so they never randomly double click on any unknown file to blow up their pc without knowing what's gonna happen with that file!

So, Linux is not such a complicated OS or you shouldn't have to be a computer expert to use Linux. Anyone can use Linux these days. Because most of its applications are getting user-friendly day by day and getting GUI-based. But you need to know some basic or essential Linux commands to operate it smoothly.

In Ethical hacking, we use Kali Linux which is also a Linux Distribution. But its made for security professionals because it comes with in-built so many useful penetration testing tool and some more modification which comes handy while penetration testing.

Here are some Useful Linux Keyboard shortcuts:-

Basic editing

Ctrl+X -Cut line (empty selection)

Ctrl+C -Copy line (empty selection) Alt+ ↓ / ↑ Move line down/up

Ctrl+Shift+K -Delete line

Ctrl+Enter / Ctrl+Shift+Enter -Insert line below/ above

Ctrl+K Ctrl+I -Show hover

In the next chapter, we will discuss more mostly used Linux commands. 

Till then keep exploring and Happy Learning.

Ethical Hacking For Beginners (Chapter-3)

Steps used in Ethical Hacking:-

There are mainly 5 steps in ethical hacking/ cyber security.

1. Reconnaissance

2. Scanning

3. Gaining Access

4. Maintaining Access

5. Clearing Track

1. Reconnaissance:- 

The process of collecting information about your defined target in depth is known as reconnaissance. Attackers perform this step before diving into any hacking attack. It’s basically a data collection procedure for the targeted victim. It contains several smaller steps also that are:-

• Footprint:- Gathering data about the target system. It mostly scans the OS, firewall, IP address, Server details, ISP/ VPN details of the target system.

• Enumeration:- This is the substep of reconnaissance where the attacker tries to find out the victim’s Name, System’s name( for future attack mostly social engineering attacks.

• Scanning:- The most important step is to find all the machines/ servers in a network/ framework (mostly in LAN mode) associated with a networking device (router) and scan it's an open port for performing an attack to compromise a group of systems or an organization.

2. Scanning:- 

The second step after defining and doing background research about the target victim/ system/ organization.

There are a few types of scanning attempts attackers do they are mostly:-

• Network Scan:- Scanning of victim’s computer’s Open ports, IP address, the running process in that system, OS details, system configuration etc.

• Port Scan:- It’s similar to finding the backdoor of the victim’s system by using which attacker will gain access later. It include TCP/UDP port scans also

• Vulnerability Scan:- FInding the weakness of the victim's system. Now weakness depends upon various factors. The most common weakness(Vulnerability) is OS vulnerability(outdated OS) and Network vulnerability(Unencrypted network/ using public network/Wifi). And some others are not using firewalls, using unauthenticated software/ keygen which mostly contains malware.

3. Gaining Access:- 

Now comes the actual step. Gaining access to the victim's system. There are several methods available for gaining access. Most common are:-

• Password cracking:- most common password cracking methods are brute force, dictionary attack, rainbow table attack, phishing, social engineering, malware attack.

• Unsecured Network:- If the victim using a network which don’t have any encryption, or using any public network,

• Spyware:- Most common method, sending spyware through email, any software or through any communication medium to the victim's system and gaining access to that system through that spyware. (mostly trojan)

• Session Hijacking/ Man in the middle:- This attack is performed using session cookie hijacking from the victim’s browser or through getting access to the victim's unprotected network. And in this case, the attacker silently captures the in/outbound data transmitting from the victim's system.

• Phishing attack:- In this case victim is being tricked by the attacker to enter his/her credentials to a fake website/ system without identifying that fake system. Most attackers send a fake link through mail/ other communication medium pretending to be a legitimate authority.

• Data Breach:- Nowadays it is the most common way of getting the victim of cyber fraud. And it’s out of the end user’s control. Most attackers target the big companies’ user database and find out user information, id card, email id, location, and in fact credit card details too.

To avoid this type of attack users are always warned to change their credentials at least once in a month(basically password/ security pin). And never share any sensitive information through phone or mail without being sure that the person on the other side of the phone/ mail is 100% legitimate.

4. Maintaining access:-

The step is when an attacker tries to maintain the access/ ownership which he gained over the victim’s machine. For this step, they use the backdoor, rootkit, rat, trojans, etc. And they try to upload sensitive data from the victim’s pc to their server or system. (which they use at a later point of time for blackmailing/ threatening the victim) And after that in some cases, they lock(Encrypt) the victim’s PC and ask for ransom (bribe) to unlock the PC(Ransomware attack). And mostly they just take the ransom and fly away.

5. Clearing Track:- 

After performing a successful attack the attacker clears all the evidence of that attack so that cyber forensic experts can’t trace back them or can’t take any legal action. In this step attackers mostly clear all the log files from the victim's PC as well as their own PC too, Clears up all connections which they established, destroy all the payloads, rootkits, rats, trojans, etc. And in some cases, they also destroy their systems too after backing up all the data from it so that nobody can’t trace it back them.

In the next chapter, we will discuss Linux. So stay tuned and Happy Learning!.

Ethical Hacking For Beginners (Chapter-2)

In this Chapter of the Ethical Hacking for Beginners series, we are going

to learn some of the most used Ethical Hacking Terminologies.

Which you'll need to understand how ethical hacking works.

Some Ethical Hacking Terminologies:-

• Adware:- A piece of code/ Software/ script used to show forcefully ads by getting into your system/ browser without your permission.

• Attack:- An action performed to get into your system forcefully without your permission.

• Backdoor:- Basically a method of bypassing authentication in a computer/ system/network. Used by Trojan mainly for obtaining remote access to your system. And spying upon you.

• Breach:- When a hacker successfully exploits a system and gains access to that system or its files or network and most of the cases leak sensitive data or sells them.

• Bugs:- A vulnerability/ weakness in a system/ software/ network/ device. Which was made by developers unintentionally or by mistake.

• Bot:- Short form of robot. Basically, an automated program is used to perform the same task repeatedly for a huge number of time. Like trying different passwords in a login form to get access, where there is no human interaction. The whole script is being run by that bot.

• Buffer Overflow:- A flaw in a program that leads to overflow in a memory block (called buffer memory) by entering data more than the capacity of that memory block and making other data overwritten by that newly entered data and in most of the cases gaining access to that system.

• Deep Fake:- And edited audio or video clip manipulated to seem real or believable. Mostly created/ edited using softwares.

• Encryption:- Process of encoding data to prevent data theft. Only decoded by a virtual key(secret set of data(string))

• Exploit:- A piece of code/ script/ software used to take advantage of a bug or may be to compromise the security of a computer system.

• Pentesting:- Short of Penetration Testing. means of evaluating security using hacker tools and techniques with the aim of discovering vulnerabilities and evaluating security flaws.

• Quarantine:- The process of isolating a file suspected of being infected with a virus in a storage device in order to prevent it from contaminating other files or other drives. Antivirus uses this feature to prevent virus infection in a system.

• Spam:- An unsolicited email/ junk email sent to a group of recipients without their consent. Mostly for advertising or hacking(phishing) purposes.

• Threat:- Possible danger which can compromise a system/ network using a vulnerability/ exploit.

• Vulnerability:- A weakness in a system/ program/ network by using which a hacker can gain access in that system and compromise that system.

These are some of the most important terminologies for ethical hacking.

There are so many others also. Will discuss and introduce those later

during the tutorial.

Ethical Hacking for Beginners (Chapter -1)

 

What is Ethical Hacking?

Hacking is basically the activity of identifying a vulnerable (Weak) computer system or a computer network and gaining access(penetrate through) to that system to get personal data or compromise that system or take over that system. Ethical hacking is that same thing but doing it legally or ethically (you can say ‘safe practice’) by taking permission(Mostly written) from that authority on which you are going to penetrate through their system so that if anything happens (damage) by your side unintentionally to that authority or to someone who is connected with that authority, they can’t sue you up.

Types of Hackers:-

These are Major types of hackers you can see through the globe:-

1. Blackhat Hackers(Crackers):- These are the bad guys. Who gains unauthorized access to a system. And steal personal data/ money, misuse them or may compromise or damage your system, violate policy regulations, or may blackmail you for anything(mostly money or sensitive data).
2. Whitehat Hackers(Ethical Hackers):- These are the good guys or you can say Cyber Security tester. Who can hack into your system with your permission and let you know about your system's vulnerability or let you know about new security threats and vulnerabilities to make you safe from the latest security threat or data breach.
3. Greyhat Hackers(Mixed of two):- These are the mixed kind of guys who may be doing hacking for fun or may be trying to be cool by doing hacking activity. They might hack into your system without your permission or may contact you to let you know your system’s vulnerability. Or may sell your personal data, that totally depends upon them.

Apart from these are the 3 types you can see some other non-popular types of hackers:-

1. Hacktivists:- These are mostly a group of hackers or maybe an individual whose motive is to hack a system for social or political or religious reasons and after that, they just leave their message on that compromised system. In most of the cases, they don’t damage/harm the system. Eg:- Anonymous group
2. Script Kiddies:- These are the newbies who have almost 0 knowledge about computer systems(Mostly Programming Language or networking) but passionate about hacking. So they copy other hackers' tools or scripts or methods to hack.

What are the skills you require to be an Ethical Hacker?

1. You should have to familiar with Linux Environment
2. Basic and good understanding of Computer Networks (How network protocols work, what is ports etc.) & Familiar with Databases.
   
3. Good understanding of Computer hardware(Computer Architecture, Memory blocks, Buffer, Cache, virtualization, bios, firmware) & network security(eg.- firewall, IPS, IDS, Proxy, VPN)
4. Very good understanding of Various programming/ scripting languages ( Python, Bash, Java, HTML, PHP, C, etc.)
   

*If you don’t have any of these skills, don’t worry, I will teach you everything. You just have to know how to use a computer, That's it. Rest of all I will cover.

What are the basic types of cyber attacks?

• Malware Attack(Virus, worms, trojan, rootkit, spyware, adware, ransomware, 
• Phishing Attack
• Keylogging Attack
• Man in the Middle (MITM) attack
• SQL Injection
• Denial of service (DoS) attack
• Social Engineering attack
• Zero-day Exploit attack
• DNS Spoofing attack
• Cross-site scripting (XSS) attack
• Session Hijacking attack
• Insider Threat 
• Birthday Attack
• Brute Force Attack   Etc.

*(Will discuss these all methods later with examples.)

What are the Safe Practices in Ethical hacking?

• Stay Legal:- Get a proper approval before penetrating through someone’s system.
• Don’t Push Your Limit:- Work in between the safe zone. This means in which area only you got the approval to work on work only in that area. (Eg.:- You got an approval of vulnerability analysis of a website from a client so you will only penetrate through that website, not the other sites it’s backlinked(connected) to) 
• Respect Others Privacy:-  Don’t misuse others data while you get the approval to penetrate through one’s system. Maybe in some cases you have to sign an NDA(Non-disclosure agreement). If you are found to be disobeying that agreement they can sue you up.
• Report Vulnerability:- As you’re working as an Ethical Hacker your work is to notify the organization about the vulnerability not to misuse that vulnerability.
• NEVER WORK FOR ANY UNAUTHORISED PARTY:- Yes this is the most important point which you will face several times in your Cyber Security / Ethical Hacking career, when you will be treated as an Ethical Hacker. Maybe your friend will ask you to hack his girlfriend’s Facebook account or hack someone’s website to download some premium content for free. NEVER DO THAT. I repeat NEVER DO THAT. You will get sued legally for that, and maybe your Ethical Hacking career gets spoiled as well. Who’re they to order you to penetrate through facebook’s system? Do they have a written permission from Facebook? Or from the service provider? If they gave you one, verify that, I’m sure that will be fake. Facebook never gave permission to hack an individual's personal account. Yes, they have a bug bounty program but that is another thing (I will discuss that later.). I have already faced this same issue so many times in my career.

What are the Cyber Security certifications you can get and you will need:-

• CEH (Certified Ethical Hacking) certification from EC Council
• CHFI(Computer Hacking Forensic Investigation) Certification from EC Council
• CompTIA security+
• CCNA(Cisco Certified Network Associate)
• CCNP(Cisco Certified Network Professional)
• LPT (Licenced Penetration Tester) 
• NPT (Network Penetration Tester)
• WAPT(Web Application Penetration Tester)
• CND(Certified Network Defender) etc.

We will discuss some ethical hacking/ Cyber Security terminologies and their details in the next chapters. Till then Happy learning.✌

If you have any doubts or queries please comment down below I'll try to answer them all.

5 Tech Hacks that will make your life easier

 

1. Watch age restricted YouTube videos without logging in:-

Surfing internet into incognito mode or from an Internet Café(without logging into your google account) and found some interesting YouTube video? but it's age restricted? !. Aw snap!.... What to do now?

well, this is the simplest solution you should try...

Just simply add nsfw before the url youtube.com it will take you to a different site, but its ok.

You can watch the video without logging into your YouTube account there and its a safe site. but the only problem is you have to deal with some annoying ads here.

And boom ! you bypassed the YouTube age restriction.

Happy surfing !!😁

Before putting nsfw

After putting nsfw

N.B.:- This trick is just for educational purpose. Please don't Misuse this trick. Misusing this trick may create legal issues.

2. How to check Windows Build version:-

If you are a windows user you may face this issue while installing any 3rd party software that build version not compatible with this software error. Until you find your PC's build version you can't find out the right software that is compatible with your PC. So how to find it ?

Just go to start-> then Run->and type winver  this command will show you your PC's build version.

Or you can just simply press windows+ r (shortcut of run) and type winver this will do the same.

The red blocked text is the Build version

3. Re-open an accidentally closed tab in browser:- 

Reading something interesting in a tab and suddenly while closing some other tabs, accidentally closed that current tab. Oh no !!. What to do now? 

Well, you can get it from your browser history but that might be time consuming. 

But here I'll show you how to get back that closed tab within a fraction of second.

Just press ctrl+shift+t and the last closed tab will open up again. This is applicable on Most of the popular browsers like Firefox, Chrome, Explorer, Edge etc.

4. Scroll up and down in a webpage without using the mouse:-

Too lazy to scrolling in a webpage using your mouse's scroll button? or surfing from a Laptop(not gesture supported) without using Mouse?

Well, this trick can save your time and energy as well.

Just press the space bar and you can notice it is scrolling down and for scrolling up press shift+spacebar.

But it has some exceptions. It won't work on YouTube's tab as well as if you are writing something then too. And supported by most of the popular browsers like Chrome, Firefox, EDGE, and Explorer etc.

5.Convert all letters from lower case to uppercase and vice versa:-

Writing something on MS Word and notice later that Caps-Lock was on!😕. What to do now?

Will you retype the whole document again? No, that is not worthy...

So here is a trick that will save your time. All you have to do just select the letter or word or sentence or paragraph which you want to capitalize and press shift+ F3

Now you can change  among Uppercase, Lowercase, and first letter Upper rest lower case.

Let me show you an example, that will clear everything:-

Original text -> LOREM IPSUM

shift+F3-> lorem ipsum

shift+F3-> Lorem Ipsum

shift+F3-> LOREM IPSUM    

Hopefully this trick is also applicable for All Microsoft Office applications and Wordpad as well. 

But you can't use this trick in Notepad or web browser.

Well, Its good to see that you read upto this!...so, here is a bonus tech hack tip for you:-

6*. Check your PC's system properties just in a second:- 

Everybody more or less can check their system property by right clicking on My computer-> Properties. But today I'll show you the shortcut to check it up in a second.

Just simply press Windows+ Pause/Break and the system properties window will open up.

It will show something like this

How To play YouTube videos in Background (PIP mode) on Android ?

 

How to play YouTube videos in background on your Android phone? received this question from many of my friends. So the answer is according to YouTube's term and condition PIP mode(Picture in Picture mode) is only available for the users who will purchase youtube premium (@129Rs/month) and who live in United States.

So Neither I'm gonna buy premium or nor I live in US, but I want to use PIP mode anyhow. So here I find-out one hack by using which you can use PIP mode without paying any money or without relocating to the US.

You can find other alternative too that installing any 3rd party app to enable PIP mode. But here I having my trust issues (Security issues) on that 3rd parties so I'm not gonna install any other apps. 

As I'm using Stock Android I only use my in-built apps to do this hack.

So here the hack begins. To do this hack you need 3 things:- An Android device(version 8.0 or more preferable), Google chrome android browser(I'm using 85.0 version), and a stable internet connection.

So follow these steps to begin:-

Step 1:- Open Google Chrome Browser on your Android phone.

Step 2:- Open YouTube from chrome, by typing the url:- https://www.youtube.com/

Step 3:- Go to Desktop site by pressing the 3 dots menu on the top right corner.

Step 4:- Now click on Desktop Site. And now you are into desktop mode.

 

Step 5:- Now Just play any video that you like.(Preferably any playlist, else you have to change the video manually every time after it ends). And if you wish you can turn on auto play function, else you have to manually play the next video after the first one ends.

Step 6:- This is the most important step. Now as your video is playing on your screen you have to go to full screen mode. else this trick will not work. To go to full screen mode you have to click on the full screen icon which you can see the bottom right corner below the video progress bar. 

Step 7:- Now just simply click on the home button and chrome will go into background mode. But video will play into PIP mode.

How to Upload Photo/ Video to Instagram from PC ?

 

So the most important question I faced that is "HOW TO UPLOAD PHOTO/ VIDEO TO INSTAGRAM FROM PC ?"

Well the simple answer I got from from Instagram support is that:- Instagram is designed to work from its dedicated app (Android/ IOS/Windows) not from any web browser especially if its Desktop/Laptop. But it doesn't mean that you can't access instagram from PC. Yes, You can access Instagram from PC but you can't upload Photo/ Videos as well can't switch to dark mode, can't DM(Direct Message) someone, and can't upload story. So that is a huge drawback. The basic reason behind this is Instagram(Facebook Inc.) don't want that people can use their service from chrome or any other browser without downloading their app. 

But don't worry my dear friend, here I found a little instagram hack which can solve all your problem. Wanna see how ??

So let's follow my steps here.

So,the only thing you need is a PC(Desktop/Laptop) with a browser (Chrome/ Firefox) Preferable, with a stable internet connection.

So lets get started...

Step 1:- Goto https://www.instagram.com/ 

It would look something like this

Step 2:- Login to Instagram using your email and password and just hit the login button. 

Step 3:- After Login you can see the screen which is shown below. Here you can save save your Login credentials into your PC if you wish. I prefer not to save so here I select not now. You can choose save info as you wish.

Step 4:- The next thing will come that is notification preference. If you want to receive notification in your PC when the instagram tab is not opened. So here I prefer Yes, if you don't want you can choose no.

Step 5:- Now the main instagram page is opened in front of you. So here you have to right click on your mouse in the white space which you can see in the left side of your screen. after right click this menu will popup. You have to choose the last option INSPECT. 

Or you can just press ctrl+shift+I from your keyboard. This shortcut will do the same.

Step 6:- Now you can see a inspect tab has been opened at the right side of your screen. Don't be scared it looks complex but trust me its so easy. All you have to do just click on the tablet icon on the inspect tab which I marked as 1 in the below screenshot. Then you have to just reload the page using the reload button which I marked as 2.

Or you can just press F5 from your keyboard which is the shortcut for reload.

Step 7:- Now you can see One change have already happen to your screen. Look carefully at the bottom. Did you recognize the menu bar, which you can see from your instagram app in mobile?. So congratulation! you have successfully changed to mobile mode.

Step 8:- Now you have to do the same thing which you do from your mobile. Just click on the + button to add media file (image/video). Select your image(Marked as step 1), Click open(Marked as step 2)

Step 9:- Now time to adjust your media file using the button given left side(Marked step 1), and when you satisfied click next (Marked as step 2).

*One free tips you can note down here that is:- the optimum resolution for any media file for instagram is 1000*1000 pixel, which is square sized image/video. That's the best fit (you don't have to crop anything).

Step 10:- Now put your caption, Description and hashtag for your post. And just hit the POST button. And boom! you have successfully posted a media on instagram without touching your mobile! CONGRATS!. 

*One more free tips you can note down here that is instagram only support 30 hastag for a single post and 2200 character limit for caption and 150 character limit for bio. and please keep in mind that space is also counted as a character.

Step 11:- So,now I guess you don't like that complex mess kind of thing in your right side of the screen(The inspection window). So just carefully click on the cross button on that inspection window just above your scroll bar on the right side. And its gone!

Step 12:- So the last and final step is just reload your page using press F5 button from your keyboard. And you have returned to the instagram desktop mode finally.

 So now you are a pro.😎

Note:- I have done the whole process in incognito mode but don't worry, this process is applicable for normal as well as for incognito mode both.
