Top Cyber Security Threats [Updated 2023]

Much dedicated cybersecurity landscape concludes several things, which possess numerous cyber security threats that are pretty harmful to the sure-short growth of an organization.  Moreover, this vital cybersecurity landscape has several things, such as fast-changing, stressful, and sometimes downright scary.  But it’s never dull.

In addition to this, many distinguished cyberattacks are enhancing and evolving as various adversaries are working so hard to stay one step ahead of cybersecurity experts.  However, the law enforcement team in the cyber security domain needs to understand the level of work and need to respond as first responders during the time of a cyberattack.

What is Cyber Security Threats?

Cyber security threats can be defined as a type of threat that targets computer systems, networks, and devices or the data that they store or transmit.  In addition, these threats can take many forms and can be carried out by a variety of actors, including nation-states, criminal organizations, and individuals.

Moreover, these cyber security threats play the main rival roles in a business’s growth, and no organization can outrun these cyber security threats without mitigating them properly, as we are already watching a number of cyber attacks on diverse organizations’ IT infrastructures hailing from varied niches and genres.

Sources of Cyber Security Threats

In today’s era, where black hat hackers have a maximum approach to the vulnerable IoT devices all over the world, it seems that security threats can come from a variety of sources, including:

  • Nation States: Nation-states may use cyber attacks as a means of espionage or sabotage against other countries.
  • Criminal Organizations: Criminals may use cyber attacks to steal sensitive information, such as financial data or intellectual property, for financial gain.
  • Hacktivists: Hacktivists are individuals or groups who use cyber attacks as a means of promoting a political or social cause.
  • Insiders: Insiders, such as employees or contractors, may pose a threat to an organization’s cyber security if they have access to sensitive information and intentionally or unintentionally misuse it.
  • Individual Hackers: Individual hackers may carry out cyber attacks for a variety of reasons, such as personal gain, competition, or simply for the challenge.

It’s important to note that the source of a cyber security threat may not always be immediately clear, and it can be difficult to attribute attacks to specific individuals or groups.

Let us understand this with an example, last year David Colombo, founder of a cyber security company as well as a spokesperson for World Gov Summit, tweeted that he had successfully taken control of 10 Tesla driverless cars globally.

David Colombo tweeted that he had successfully taken control of 10 Tesla driverless cars globally.

This incident shows how easy it is for professional hackers to find vulnerabilities and compromise them in even the highest security commodities across the globe.

Types of Cyber Security Threats

There can be several types of cyber security threats that black hat hacking professionals can undoubtedly employ to compromise the datasets of a target organization.  Some of those types of cyber security threats are mentioned below with the top 10 descriptions:

Top 10 Cyber Security Threats

  • Malware Attacks
  • Social Engineering Attacks
  • Supply Chain Attacks
  • Man-in-the-Middle Attack
  • Denial-of-Service Attack
  • Injection Attacks
  • Password Attacks
  • Advanced Persistent Threats (APT)
  • Ransomware
  • Cloud Vulnerabilities

Now, we will describe the above-mentioned types of cyber security threats one by one in the following paragraphs:

Malware Attacks

This can be described as the abbreviation for “malicious software,” and it refers to any software that is specifically designed to harm or exploit vulnerabilities in computer systems.  Examples of malware include viruses, worms, and ransomware.

Social Engineering Attacks

Social engineering attacks are a type of security attack that relies on human interaction in order to gain access to confidential data or systems.  They are typically carried out by manipulating people into giving out sensitive information or by exploiting their trusting nature.  Common social engineering techniques include phishing, baiting, tailgating, pretexting, quid pro quo, and dumpster diving.

Supply Chain Attacks

Supply chain attacks are cyberattacks that target a company or organization’s supply chain.  These attacks utilize vulnerable points in the supply chain to gain access to a target organization’s networks, data, or systems.  In addition, supply chain attacks can occur at any point in the supply chain and can take many forms.

Moreover, they can involve malicious actors infiltrating a company’s networks and systems through third-party vendors, malware inserted into a product’s software, or counterfeit components being used in a product’s manufacturing process.  In this regard, supply chain attacks can have devastating consequences for organizations and can lead to data breaches, financial losses, and reputational damage.

To evade supply chain attacks, the target enterprises should confirm that their third-party vendors and suppliers are adequately vetted and monitored and that their products and services are secure.

Man-in-the-Middle Attack

A man-in-the-middle attack is a type of cyber attack where a malicious actor inserts themselves into a communication between two parties, either to eavesdrop on the conversation or to impersonate one of the parties and gain access to information.  In a man-in-the-middle attack, the attacker is able to intercept, send, and receive data from both parties, making it difficult to detect.

Denial-of-Service Attack

A denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting the services of a host connected to the Internet.  Denial-of-service attacks are considered violations of the Internet Architecture Board’s Internet proper use policy.

Injection Attacks

The injection attacks can best be described as a type of attack where malicious code is injected into an application or system.  In addition, these attacks can be used to gain access to sensitive data, modify or delete data, or even take control of the system.  Additionally, injection attacks can occur through a variety of methods, including SQL injection, command injection, and cross-site scripting (XSS).

As a result, this can be stated that these attacks are a common form of attack and can have devastating consequences if not prevented.

Password Attacks

Password attacks are a type of cyberattack that attempts to gain access to a system or service by guessing or cracking passwords.  In addition, these attacks can be made manually or with automated tools that use methods such as brute force, dictionary, and hybrid attacks.

Moreover, password attacks can be used to gain access to sensitive data, disrupt services, or launch other attacks.  In addition to this, to reduce the risk of a password attack, businesses should employ strong password policies and use two-factor authentication.

Advanced Persistent Threats (APT)

As the word describes, APT or Advanced Persistent Threats are highly sophisticated, targeted attacks that are used to infiltrate computer networks and systems to gain access to sensitive information or disrupt operations.  In addition, APTs are typically carried out by highly skilled, well-funded threat actors who use multiple methods to gain access, maintain persistence, and remain undetected for long periods of time.

Moreover, APTs are often used for espionage or sabotage and can have devastating consequences for organizations, governments, and individuals.


Ransomware is a type of malicious software that is used to extort money from victims by encrypting their data or locking their computer systems.  In addition, ransomware is typically spread through phishing emails or malicious websites, and once it is installed, it will encrypt the user’s data or lock the user out of their computer or device.

As a result, In order to regain access to their data or system, the victim must pay a ransom to the attacker.  Moreover, ransomware is a form of cybercrime and is becoming increasingly common, so it is important for users to be aware of the risks and take steps to protect themselves.

Cloud Vulnerabilities

The corresponding vulnerabilities possessed in a cloud server security are highly known as cloud vulnerabilities.  In addition, many organizations neglect this security plan who are working on cloud servers as they think that their cloud service provider should do these kinds of activities to secure their clients’ datasets from any illicit hacking attempt.

However, to prevent cloud vulnerabilities, this could be understood that we should always keep ourselves one step ahead of any adversary thinking capability and regularly check our plans related to securing our cloud security systems.  Moreover, there are several cloud vulnerabilities that one should check at frequent intervals, such as the following:

  • Unpatched Software,
  • Unsecured APIs,
  • Weak Authentication,
  • Inadequate Access Controls,
  • Privilege Escalation,
  • Lack of Encryption, etc.
