Types of Cyber Attacks
Hackers do many types of cyber attacks. They try every possible attack on a server or network to hack it. Below we are going to discuss some of the common cyber attacks.
#1. Malware Attacks
In this type of attack, the software developed with malicious code, usually installed on a network. Malware software includes spyware, ransomware, viruses, and worms. Can use them to get access to a computer network and run malicious commands in it.
#2. Phishing Attacks
Phishing attacks are made on the person for getting access to their online accounts. These accounts can be Gmail, Facebook, and other social media account. In this attack, a very similar-looking login page was developed on several social media websites. Then this login page is sent to the victim, and if the victim enters their login credentials, then it will automatically be sent to the hacker.
#3. Man, In the Middle
In man, a middle attack, the attacker inserts himself in the middle and executes the attack. Like a hacker can interrupt traffic from a network, he can filter or steal it. The most common example of a man-in-the-middle attack is hacking an unsecured Wi-Fi network. Unsecured public WiFi and hackers interrupt their traffic and steal important information from users connected to that Wi-Fi network.
#4. Denial of Services
In the Daniel of service attack, an attacker stands a very large amount of traffic to a system or server so that the server can crash. Once the server or network is crashing, the attacker can start hacking it. Attackers use a technique in which a tremendous amount of traffic is sent, to the network in significantly less time to exceed its bandwidth and server crash. When the server crashes, the network gets offline, and attackers can start searching for security holes.

SQL is a database used by many web applications and websites. In SQL attacks, a hacker gets access to the SQL database, and it is very dangerous. Suppose a hacker had gained access to the SQL database of a website, then he will be able to see the passwords of the admin as well as users. It means that we have complete access to that website or web app’s backend.
#6. Zero-Day Exploit
A website on the dark web, known as zero-day. Zero-day is a social network for hackers. Zero-day contains hacking instructions for several applications, hacked by other hackers, and posted on zero-day. They are freely available on the zero-day website, and anyone can see how to hack that specific application on zero-day. These types of attacks, known as zero-days, and developers have to fix them as soon as possible.

For example, if there is a website with a domain, www.mydomain.com and hackers hack this website’s DNS server and send traffic to www.hackersdomain.com. Whenever anyone visits www.mydomain.com, will redirect to www.hackersdomain.com without his permission.
