What Is Hacking? How To Prevent Ourselves From Hackers

WHAT IS HACKING?

Hacking is identifying  weakness in computer systems or networks and to exploit their weaknesses to gain access. And while hacking might not always be for malicious purposes, nowadays most references to hacking, and hackers, characterize it/them as unlawful activity by cybercriminals—motivated by different factors like financial gain, protest, spying, and even just for the fun of the challenge.

Computers have become important to run  successful businesses. It is not sufficient to have isolated computers systems; they need to be networked to enhance communication with external businesses. This leads to their exposure in the outside world and hacking.

Hacking is typically technical in nature, but hackers can also use psychology to trick the user into clicking on a malicious attachment or providing personal data. These tactics are referred as “social engineering.”

WHO IS A HACKER?

A Hacker is a person who detects and exploits the weakness in computer systems and/or networks to gain access. Hackers are usually skilled computer programmers with great knowledge of computer security. Hacker is usually referred as to some self-taught or rogue programmer who is skilled at modifying computer hardware or software so it can be used in ways outside the original developers' intent.

TYPES OF HACKERS

  • Ethical Hacker: A hacker who gains access to systems with a view to fix the identified weaknesses if present in the system.

  • Phreaker: A hacker who identifies and exploits the different weaknesses in telephones instead of computers. 

  • Grey hat: A hacker who breaks into computer systems without authority with a view to identify weaknesses and reveal them to the system owner. 

  • Hacktivist: A hacker who use hacking to send different social, religious, and political, etc. messages. This is generally done by hijacking websites and leaving the message on the hijacked website. 

HOW HACKERS WORK?

The main resource on which the  hackers rely upon, apart from their own ingenuity, is computer code. While there is a large community of hackers on the internet, only a relatively small number of hackers actually program code by own. Most of the  hackers seek out and download code written by the other people.

  • Log keystrokes: Some programs allow hackers to review every keystroke a computer user makes on his/her computer. Once the program is installed on the user’s computer, the programs record each and every keystroke, giving the hacker everything he requires to infiltrate a system or even steal someone's identity.

  • Create zombie computers: A zombie computer, or bot, is a computer which is used by hacker to send spam or commit Distributed Denial of Service (DDoS) attacks.

  • Gaining backdoor access: It is similar to hacking passwords.In this, some hackers create programs that search for unprotected pathways into different  network systems and computers.

  • Infect a computer or system with a virus: Computer viruses are programs designed to duplicate themselves and cause problems to the user ranging from crashing a computer to wiping out everything on a system's hard drive.

THINGS HACKERS CAN DO TO US

HOW TO PREVENT OURSELVES FROM HACKERS

  • By destroying all traces of your personal info on hardware you plan on selling, this makes information difficult to recover. 

  • By creating difficult passwords, and never using the same ones across multiple services For extra hacker protection,you can ask about two-step authentication.

  • By updating  your OS and other software frequently, if not automatically. This prevents users from  hackers who are willing to accessing their computers through vulnerabilities in outdated programs (which can be exploited by malware.

  • Some websites will ask you to sign in with a specific service to access features. Ensure the login option isn’t a sneaky phish, and if you’re giving permission to an app to perform a task, ensure you know how to abolish access once you no longer need it.

  •  By downloading software from sites you trust and by properly  and carefully evaluating free software and file-sharing applications before downloading them for use.

CONCLUSION

To take it a step further, you can protect your computer from hackers by using a spam filter or gateway to scan inbound email or instant messages.
