Different Types of Cyber Security Threats

A cybersecurity threat is a hostile and intentional attack by an individual or organization on another individual’s or organization’s network to steal or destroy IT assets, computer networks, or any other type of sensitive data.

While the variety of cyber crimes continues to expand, there are some of the most typical and widespread cyber threats that modern enterprises must be aware of.

The following are the top nine cyber security threats:

  1. Malware

The most prevalent cyber security hazards are malware assaults. Malware is described as harmful software, such as ransomware, spyware, viruses, and worms, that enters the system after the user clicks on a malicious link or email. Once within the system, it can, among other things, block access to essential network components, harm the system, and acquire private information.

  1. Phishing

Malicious emails are sent by cybercriminals that appear to come from genuine sources. The victim is then duped into clicking the malicious link in the email, which results in installing malware or revealing sensitive information such as credit card numbers and login passwords.

  1. Man in the Middle Attack

This attack happens when cybercriminals insert themselves between two parties in communication. Once the attacker has interpreted the message, they may extract and collect sensitive information and respond to the user in various ways.

  1. Denial of Service Attack (DoS)

Denial of Service attacks attempt to overwhelm systems, networks, or servers with traffic, rendering the system unable to fulfill valid requests. Infected devices can also be used to initiate an assault on the target system. This is known as Distributed Denial of Service (DDoS) assault, an advanced version of DoS.

  1. SQL Injection

A SQL injection attack happens when fraudsters attempt to access a database by sending harmful SQL scripts. Once successful, the malicious actor can access, modify, or remove data contained in the SQL database.

  1. Ransomware

Ransomware is a computer attack in which the attacker encrypts or locks the victim’s data and threatens to expose or prevent access to the data if a ransom is not paid. Learning more about these threats can help businesses avoid them.

  1. DNS Attack

A DNS assault is a type of cyberattack in which cybercriminals take advantage of the Domain Name System (DNS) flaws. The attackers use DNS vulnerabilities to redirect website users to malicious domains, also known as DNS Hijacking, and remove data from vulnerable computers.

  1. Zero-day attack

This attack occurs when a software or hardware vulnerability is revealed, but hackers have already exploited said vulnerability before a patch or remedy is released.

  1. Advanced Persistent Threats (APT)

When a hostile actor acquires unauthorized access to a system or network and remains undiscovered for a long time, this is considered an APT.


Cyber assaults have gotten much too advanced. As a result, firms that rely on antiquated cybersecurity measures leave themselves exposed to a cyberattack. Hence, organizations must improve their cybersecurity program to combat these attacks. An effective cybersecurity program may assist firms in preventing attacks, reducing recovery time, and containing future risks.
