Types of Hacker

Let’s see the categories of Hackers on the basis on their knowledge. Coders **The Real Hackers are the Coders, the ones who revise the methods and create tools that are available in the market. Coders can find security holes and weaknesses in software to create their own exploits. These Hackers can use those exploits to develop fully patched and secure systems.

Concept of Ethical Hacking

hi guys this is my first post i hope to present hacking A to Z 101 lets begun :) Hacking The Art of exploring various security breaches is termed as Hacking. # Computer Hackers have been around for so many years. Since the Internet became widely used in the World, We have started to hear more and more about hacking

Why Hackers Hack?

The main reason why Hackers hack is because they can hack. Hacking is a casual hobby for some Hackers — they just hack to see what they can hack and what they can’t hack, usually by testing their own systems. Many Hackers are the guys who get kicked out of corporate and government IT and security organizations. They try to bring down the status of the organization by attacking or stealing information

Steps Performed By hackers

1) Reconnaissance 2) Scanning 3) Gaining Access 4) Maintaining Access 5) Clearing Tracks • Performing Reconnaissance • Scanning and Enumeration • Gaining access • Maintaining access and Placing Backdoors • Covering tracks or Clearing Log

Prevention from Hackers

What can be done to prevent Hackers from finding new holes in software and exploiting them? Information security research teams exist—to try to find these holes and notify vendors before they are exploited. There is a beneficial competition occurring between the Hackers securing systems and the Hackers breaking into those systems. This competition provides us with better and stronger security, as well as more complex and sophisticated attack techniques.

Email hacking

How Email Works? 

 Email sending and receiving is controlled by the Email servers. All Email service providers configure Email Server 
before anyone can Sign into his or her account and start communicating digitally.

 Once the servers are ready to go, users from across the world register in to these Email servers and setup an 
Email account. When they have a fully working Email account, they sign into their accounts and start connecting 
to other users using the Email services.

 Email Travelling Path

 Let’s say we have two Email providers, one is Server1.com and other is Server2.in, ABC is a registered user in 
Server1.com and XYZ is a registered user in Server2.in.

 ABC signs in to his Email account in Server1.com, he then writes a mail to the xyz@server2.in and click on Send 
and gets the message that the Email is sent successfully.

 But what happens behind the curtains, the Email from the computer of abc@server1.com is forwarded to the 
Email server of Server1.com. Server1 then looks for server2.in on the internet and forwards the Email of the 
server2.in for the account of XYZ. Server2.in receives the Email from server1.com and puts it in the account of 
XYZ.
 XYZ then sits on computer and signs in to her Email account. Now she has the message in her Email inbox.

Email Password Hacking

Email Password Hacking

There is no specified attack available just to hack the password of Email accounts. Also, it is not so easy to 
compromise the Email server like Yahoo, Gmail, etc.

Email Password Hacking can be accomplished via some of the Client Side Attacks. We try to compromise the user 
and get the password of the Email account before it reaches the desired Email server.

We will cover many attacks by the workshop flows, but at this time we will talk about the very famous 'Phishing 
attack'.

Phishing


The act of sending an Email to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.

The Email directs the user to visit a Web site where they are asked to update personal information, such as passwords and credit card, social security, and bank account numbers, that the legitimate organization already has. The Web site, however, is Bogus and set up only to steal the User’s information.

Phishing scams could be

Emails inviting you to join a Social Group, asking you to Login using your Username and Password.

 Email saying that Your Bank Account is locked and Sign in to Your Account to Unlock IT.

 Emails containing some Information of your Interest and asking you to Login to Your Account.

Any Email carrying a Link to Click and asking you to Login.

Prevention against Phishing

Read all the Email Carefully and Check if the Sender is Original

 Watch the Link Carefully before Clicking.
 Always check the URL in the Browser before Signing IN to your Account
Always Login to Your Accounts after opening the Trusted Websites, not by Clicking in any other Website or Email.

network resources. Multiple accounts at the target site may be abused, increasing the denial of service impact.







Email Spamming

 

  Email Spamming is a variant of Bombing; it refers to sending Email to hundreds or thousands of users (or to lists 
that expand to that many users). Email spamming can be made worse if recipients reply to the Email, causing all 
the original addressees to receive the reply. It may also occur innocently, as a result of sending a message to

Email Spoofing

Email Spoofing

 







Email spoofing is the forgery of an Email header so that the message appears to have originated from someone or
somewhere other than the actual source. Distributors of spam often use spoofing in an attempt to get recipients 
to open, and possibly even respond to, their solicitations. Spoofing can be used legitimately.

There are so many ways to send the Fake Emails even without knowing the password of the Email ID. The Internet 
is so vulnerable that you can use anybody's Email ID to send a threatening Email to any official personnel. 

Methods to send fake Emails 

1.Open Relay Server

2.Web Scripts

 Fake Emails: Open Relay Server

 An Open Mail Relay is an SMTP (Simple Mail Transfer Protocol) server configured in such a way that it allows 
anyone on the Internet to send Email through it, not just mail destined ‘To’ or  ‘Originating’ from known users.

An Attacker can connect the Open Relay Server via Telnet and instruct the server to send the Email.

Open Relay Email Server requires no password to send the Email

 Fake Emails: via web script

 Web Programming languages such as PHP and ASP contain the mail sending functions which can be used to send Emails by programming Fake headers i.e.” From: To: Subject:”

 There are so many websites available on the Internet which already contains these mail sending scripts. Most of 
them provide the free service.

Configuring an Email Server

Configuring an Email Server

 





 Email server software like Post cast Server, Hmailserver, Surge mail, etc can be used to convert your Desktop PC
into an Email sending server.

  HMailServer is an Email server for Microsoft Windows. It allows you to handle all your Email yourself without
having to rely on an Internet service provider (ISP) to manage it. Compared to letting your ISP host your Email,
HMailServer adds flexibility and security and gives you the full control over spam protection

Email Service Protocols

 

 SMTP

 SMTP stands for Simple Mail Transfer Protocol. SMTP is used when Email is delivered from an Email client, such as
Outlook Express, to an Email server or when Email is delivered from one Email server to another. SMTP uses port
25.

 POP3

POP3 stands for Post Office Protocol. POP3 allows an Email client to download an Email from an Email server. The
POP3 protocol is simple and does not offer many features except for download. Its design assumes that the Email
client downloads all available Email from the server, deletes them from the server and then disconnects. POP3
normally uses port 110.

IMAP


IMAP stands for Internet Message Access Protocol. IMAP shares many similar features with POP3. It, too, is a
protocol that an Email client can use to download Email from an Email  server. However, IMAP includes many
more features than POP3. The IMAP protocol is designed to let users keep their Email on the server. IMAP
requires more disk space on the server and more CPU resources than POP3, as all Emails are stored on the server.
IMAP normally uses port 143.
