- There are majorly 8 types of cyber-attacks namely, malware, phishing,

injection and zero-day exploits.
Types of Cyber Attack
-
Malware: It refers to any type of software that aims to damage a single computer,
server, or network of computers. Ransomware, spyware, worms, viruses, and
Trojans are all types of malwares.
-
Phishing:
It is the method used to attempt to gather personal information through
fraudulent emails and websites.
-
Denial of service attacks: A denial of service (DoS) attack is an attack that aims
to shut down a machine or network so that it becomes inaccessible to target
users. an accident.
-
Man-in-the-middle (MitM) attacks: These are also known as eavesdropping attacks,
occur when attackers participate in a reciprocal transaction. As soon as
attackers stop the traffic, they can filter and steal the data.
-
SQL Injection: SQL (pronounced тАЬSequelтАЭ) is the abbreviation for Structured Query
Language, a programming language for communication with databases. Many servers
that store critical data for websites and services use SQL to manage the data
in their databases. The SQL injection attack specifically targets this type of
server and uses malicious code to trick the server into divulging information
that it normally would not divulge.
-
Cross Site Scripting (XSS): Similar to an SQL injection attack, malicious code is
also smuggled into a website in this attack, but the website itself is not
attacked. In contrast, the malicious
code smuggled in by the attacker only runs in the user's browser when the
attacked website is visited and is sent directly to the visitor, not to the
website.
-
Social engineering: It is an attack that relies on human interaction to trick users into violating
security procedures in order to obtain confidential information that is
generally protected.
