Types of cyber threats

The threats that cybersecurity faces are three:

  • The Cybercrime includes individuals or groups who attack systems for financial gain or causing disruptions.
  • The cyber attacks often involve collecting information for political purposes.
  • The cyberterrorism aims to weaken the electronic systems for panic or fear cause.

But how do malicious actors get control of computer systems? Here are some of the common methods used to threaten cybersecurity:

Malware
"Malware" refers to malicious software. As one of the most common cyber threats, malware is software that a cybercriminal or hacker has created to disrupt or damage a legitimate user's computer. Often spread via an unsolicited email attachment or legitimate-looking download, malware can be used by cybercriminals to make money or to carry out political cyberattacks.

There are different types of malware, including the following:

Viruses - A program capable of replicating itself, which embeds itself in a clean file and spreads throughout the computer system and infects files with malicious code.
Trojans - A type of malware that masquerades as legitimate software. Cybercriminals trick users into uploading Trojans to their computers, where they cause damage or collect data.
Spyware: a program that secretly records what a user does so that cybercriminals can make use of this information. For example, spyware could capture credit card details.
Ransomware - Malware that locks a user's files and data, threatening to delete them, unless a ransom is paid.
Adware - Advertising software that can be used to spread malware.
Botnets - Malware-infected computer networks that cybercriminals use to perform online tasks without user permission.
SQL code injection
An injection of SQL (Structured Query Language) code is a type of cyber attack used to take control and steal data from a database. Cybercriminals exploit vulnerabilities in data-driven applications to insert malicious code into a database using a malicious SQL statement. This gives them access to the confidential information contained in the database.

A data center technician should answer questions and take queries from various sources and provide them with the right information.

Phishing
The Phishing is when cyber criminals attack their victims with emails that appear to be from a legitimate company requesting confidential information. Phishing attacks are often used to induce people to hand over their credit card details and other personal information.

Man-in-the-middle attack
A “Man-in-the-middle” attack is a type of cyber threat in which a cybercriminal intercepts the communication between two individuals to steal data. For example, on an insecure Wi-Fi network, an attacker could intercept data that is transmitted from the victim's device and the network.
