Cybercriminals are finding different kinds of ways or creating their own method to do cyber attacks. Because of that, it is very difficult to stay safe on the internet these days.
In this article, we are going to discuss what is cyber-attack and a basic idea of how many ways a cyber attack can happen and how we can prevent this. So, let’s get started.
What is Cyber Attack?
A cyber attack is a criminal offense on the Internet that happened by cybercriminals, using one computer or network to another.
Cybercriminals are creating viruses; they spread those viruses to one or more computers or the network. And after that these viruses take one computer’s information, breach or cripple them.
Types of Common & Dangerous Cyber Attacks
There are many kinds of cyber attacks we can find nowadays. But there are four kinds of attacks that are very common and popular. Here we are going to discuss the attacks and giving you valuable information on these dangerous types of cyberattacks.
Basically, Malware is nothing but a virus made by hackers and they send that virus to the victim’s computer. Because of that virus, the computer can be breached, or disable.
Many times the attackers steal the data of that computer using that virus. It looks very cool but It is one of the most dangerous cyber attacks in the world. It can harm an organization very much.
So, for any company, cybersecurity is very important nowadays. This malware has also many types such as Ransomware, command and control, spyware, etc.
Phishing is a very common and dangerous cyberattack these days. Anyone can possibly get tricked by phishing. So, What is actually Phishing? How do Phishing attacks happen? How the hackers scam you? Let’s discuss it in detail.
Phishing is one cyberattack that can be conducted by email, telephone, fake website, social media networks, etc. The attackers can connect you through the above ways and then they may offer you good deals and can use a trustable party (organization) name and fool you and take your all credentials and private data.
Sometimes they send you some links and bribe you for shopping vouchers, coupons, deals, big lottery winning, etc, and then redirect you to their spoof website that can be looked at as exactly the same as the original website but the URL always be fake. If you are not aware of the URL and if you logged in as a user then you might become the victim of Phishing.
They will get your all information with your social media details, username, passwords, and other private details. If by any chance you have purchased anything from those sites, then first you may never get the product, and also they take your bank details, debit/credit credentials. So, If you are a citizen of the Internet then you should always aware of Phishing.
3. SQL Injection
By the name, you can have an idea that it is an attack that happens in the database area. Actually, in this attack, the hackers interfere with the queries of the application’s database.
The attacker can modify or delete the data of the application using SQL injection. Because of this, the application will disable or work differently. This can change the whole behavior of that application.
There are many types of SQL Injection attacks that happen on a regular basis. Here are few examples:
UNION Attacks: In this attack hackers, can retrieve data from the database tables.
Blind SQL Injection: Here the results of a query, attackers control is not returned to the application. and then the application failed to respond.
Retrieve Hidden Data: In this technique, cyberbullies can modify or delete your complete data from your database.
Subverting Application Logic: where hackers change the queries to interfere with the application’s logic.
Examining the Database: By this, the attackers pull the information structure of the application’s database.
There is a wide range of SQL injection attack examples available but these are the very common attacks you can possibly see.
A denial-of-service or DOS attack is an attack by which the hacker can shut down your computer or your internet network. It means they can completely cut you out from your computer or network and make it inaccessible to you.
This is a very dangerous cyberattack among all. How do they do that? Normally they flood you with traffic or they send you some information which causes the crash.
Then the computer or the application system or the network will be completely taken down. There are few kinds of dos attacks we can find these days. Such as Volume-based attacks, Protocol attacks, Application Layer attacks, etc.
