Basic ideas of hacking | What is hacking

Let's ENTER into the world of HACKERS...

Whenever you encounter the word hacking, you probably associate it with sending an encrypted program to another user, and then being able to get unauthorized access on a remote computer. However, the term hacking was used to define any act of tinkering a computer’s hardware or software other than its intended use, in order to improve it and find out how electronic devices can work electronically. While that definition technically still holds true, hacking has definitely made a whole new turn especially when it comes to how another person can access someone else’s computer. Before you think that hacking is all about getting past securities to wreak havoc on somebody else’s digital device, you might need to know the types of hackers and hacking that exist nowadays.

What is hacking?

                        The most fundamental meaning of hacking is gaining unauthorized access to data in a system or computer.

"Hacking is exploiting security controls either in a technical, physical or a human-based

element." ~ Kevin Mitnick

                              However, the word “hacking” has two definitions. The first definition refers to the hobby/profession of working with computers. The second definition refers to modifies computer hardware or software in a way that changes the creator’s original intent.

It is the art of exploiting computers to get access to otherwise unauthorized information.

Now that the world is using IT systems to gather, store and manipulate important information there is also a need to make sure that data is secure. However, no system is

without is problems. Holes are often present within security systems which, if exploited,

allow hackers to gain access to this otherwise restricted information.

Difference Between Hackers And Crackers

A Hacker is a person who is interested in the working of any computer Operating system. Most often, Hackers are programmers. Hackers obtain advanced knowledge of operating systems and programming languages. They may know various security holes within systems and the reasons for such holes. Hackers constantly seek further knowledge, share what they have discovered, and they never have intentions about damaging or stealing data. 

A Cracker is a person who breaks into other people systems, with malicious intentions. Crackers gain unauthorized access, destroy important data, stop services provided by the server, or basically cause problems for their targets. Crackers can easily be identified because their actions are malicious.

How to hacking a computer?

• DNS spoofing
• Malware-Injection Devices
• Cracking Password

How to learn hacking?

                               Hacking is illegal..but for those how are interested in the hacking field, the best way is to study good hacking or ethical hacking. the role of an ethical hacker is to save from other bad hackers and reduce cybercrime. we can learn ethical hacking through many ways, from youtube, online websites and many institutes are their in our location. we can learn hacking ourselves,but we want basic skills in Intermediate computer skills,Good networking skills

What are the types of hackers? 

Hacker means some who exploit others' devices without their admittance. There are 3 types of hacking:

1. White hat hackers: white hat hackers are good hackers. they are also known as ethical hackers. Ethical hackers also make it a point that they discover new ways to learn how an electronic device can be tinkered with to maximize its efficiency. For this reason, they build communities that allow them to crowdsource their knowledge in order to improve the way people use their devices
2. Grey hat hackers: Grey hat hackers are hackers with good intentions but at times without permission. As the name suggests, they are driven by white and black hat hacking motivations – they are the ones who employ both illegal and legal techniques to exploit or improve a system. However, if a grey hat hacker exploits another person’s system, he typically makes it a point to inform the owner of the exploits made and then offers suggestions on what can be done to buff up system security.
3. Black hat hackers: A black hat hacker (or black-hat hacker) is a hacker who disregards computer security for their own personal benefits or out of evilness.Also known as criminal hackers or crackers, these people are those that maliciously gain access to another person’s system for selfish gain. They typically hack electronic devices and modify, steal, or delete critical files for their personal gain

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.
Coders are the programmers who have the ability to find the unique vulnerability in existing software and to create working exploit codes. These are the individuals with a deep understanding of the OSI Layer Model and TCP/IP Stacks.

Admins: Admins are the computer guys who use the tools and exploits prepared by the coders. They do not develop their own techniques, however they uses the tricks which are already prepared by the coders. They are generally System Administration, or Computer Network Controller. Most of the Hackers and security person in this digital world come under this category.
Admins have experience with several operating systems, and know how to exploit several existing vulnerabilities. A majority of Security Consultants fall in this group and work as a part of Security Team.

Script Kiddies: Next and the most dangerous class of Hackers is Script kiddies, They are the new generation of users of computer who take advantage of the Hacker tools and documentation available for free on the Internet but don’t have any knowledge of what’s going on behind the scenes. They know just enough to cause you headaches but typically are very sloppy in their actions, leaving all sorts of digital fingerprints behind. Even though these guys are the teenage Hackers that you hear about in the news media, they need minimum skills to carry out their attacks.

How Hackers Find Their Targets

Criminal hackers are probably among the most strategic researchers that you will encounter in the tech world. In order for a hacker to obtain as much valuable data as they can in a single attack launch, they wait for the perfect victim to show up in their sweep, study their prey, and then devise the best attack that they can muster from their skill set.

A black hat attack can target a single person or several people at a time, but most of the time, a hacker operates on a particular niche. There are hackers that would want to find vulnerabilities in banking systems online because it will provide them access to millions of deposits that they can leech through their systems. Some value personal information and proceed doing personal attacks. Some prefer to deface landing pages and broadcast their ability to get through a website’s security. Some choose to hack accounts so that they

can stay anonymous and make use of services without paying a cent. Whatever the criminal hacker’s motivation is in hacking a particular system, they will only proceed with an attack if they find that it can be done and that they can gain something out of it. With this said, the best way to prevent a hack attack is to keep valuable information from the public as much as possible. While sharing information is almost deemed a necessity nowadays, you need to make sure that you are sharing data only to legitimate users.

What does it take to become a hacker?

Becoming a great hacker isn’t easy and it doesn’t happen quickly. Being creative helps a lot. There is more than one way a problem can be solved, and as a hacker you encounter many problems. The more creative you are the bigger chance you have of hacking a system without being detected. Another huge quality you must have is the will to learn because without it, you will get nowhere. Remember, Knowledge is power. Patience is also a must because many topics can be difficult to grasp and only over time will you master them.

Cybersecurity

cybersecurity is the protection of systems, networks and programs from cyber attacks. These cyberattacks are generally pointed toward getting to, changing, or obliterating delicate data; coercing cash from clients; or interfering with ordinary business processes. nowadays, protection of your device is very difficult.

Measures to prevent cyber attacks

• keep your devices and software fully updated
• Ensure Endpoint protection
• Install a firewall,etc..
