Computer hackers are a hot topic in the news lately. What used to be the domain of nerdy kids in their parents’ basements is now a full-blown criminal enterprise, costing businesses millions of dollars every year. But what exactly is a computer hacker, and why are they so dangerous? In this post, we’ll take a closer look at computer hacking and dispel some of the myths that have arisen around it. We’ll also offer some tips on how to protect yourself from hacker attacks. Stay safe out there!
What is hacking?
Hacking is the act of exploiting computer systems and networks. A hacker usually breaks into a system by identifying a flaw in its design, such as an unprotected or unpatched vulnerability. Once inside the system, hackers can steal data, change records (such as deleting bank account information), and cause other damage to the network. In some cases, hackers may even take control of the entire system.
Hackers have been around since the early days of computing. In the 1960s, computer hackers were known as “phone phreaks” because they would exploit the telephone system to make free phone calls. In the 1970s, hackers started exploiting computer systems, and the term “hacker” was born.
What are the different types of hackers?
Threat actors (previously known as black hat hackers) are computer hackers who use their skills for criminal purposes. They hack into computers to steal information or damage systems, spread malware or use ransomware for profit.
Gray hat hackers are those who hack into systems without permission, but generally do not do so for personal gain or to damage the system. They may be motivated by a challenge, or simply to see if they can do it. While their actions are technically illegal, they are usually not pursued by law enforcement.
Ethical hackers (previously known as white hat hackers) are those who hack into systems with permission and generally do so in order to improve security or uncover vulnerabilities. They are also known as ethical hackers, and their actions are usually legal.
Green hat hackers are computer hackers who are not out to cause harm, but instead are in it for the learning experience or to find security flaws. They are usually white hat hackers who have turned to hacking as a way to learn more about computing and security.
Blue hat hackers are a type of computer hacker who is out for revenge. They often hack into systems for the thrill of it, but they also do it to harm others. Blue hat hackers can be very dangerous, because they often have a personal grudge against someone or something. This makes them unpredictable and difficult to stop.
Red hat hackers are a specific type of computer hacker who uses their skills to find and exploit security vulnerabilities in systems running the red hat Linux operating system. They are often hired by companies or governments to test the security of their systems and find ways to improve it.
How to Prevent Hacking
There are many simple things that you can do to protect yourself from computer hackers.
Keep Software Updated
First, make sure that your computer’s software and malware is up-to-date and has the latest security patches. This will help to close any vulnerabilities that hackers could exploit.
Use Strong Passwords
One of the best ways to protect yourself from computer hackers is by using strong passwords. A strong password is one that is difficult to guess and includes a combination of letters, numbers, and symbols. You should also never use the same password for multiple accounts. If you’re having trouble coming up with a strong password, you can use a password generator service.
Another way to protect yourself from computer hackers is by enabling two-factor authentication (2FA). 2FA adds an extra layer of security to your accounts by requiring you to enter a code from your phone in addition to your password. This makes it much more difficult for hackers to gain access to your accounts.
Browse Carefully Online
One of the best ways to protect yourself from computer hackers is to be careful about the websites that you visit. Avoid websites that look suspicious or that don’t have a padlock icon in the URL bar. Also, make sure that you’re using a secure internet connection (https instead of http).

Watch for Email Scams
Email scams are a common way for computer hackers to try to steal your personal information. They often send an email that looks like it’s from a legitimate company, like your bank, and ask you to click on a link or reply with your personal information. Be very careful about any emails that ask for your personal information, and never click on links or open attachments from people you don’t know.

Beware of Text Scams
Text scams are when someone sends you a text message asking for personal information, like your credit card number or Social Security number. They might also ask you to wire them money.

Download Apps from Legitimate Sources
Download apps from legitimate marketplaces, like Google Play and Apple Store. Be sure to check the app’s reviews to see if other users have had issues with the app. Also, be sure to read the app’s permissions to see what it is allowed to access on your device. If an app looks like it might be a scam, or if it asks for too many permissions, it is probably best to avoid downloading it.
