What is a Cyberattack? Understanding Common Types and Prevention

What is a Cyberattack?

A cyberattack is a deliberate attempt designed to compromise data, applications, or other assets by gaining unauthorized access to computer systems, networks, or digital devices. Cyberattacks are often orchestrated by cybercriminals and target one or multiple computing devices or entire networks. Malevolent cyberattacks can render computers inoperative, pilfer sensitive information, and employ the compromised systems as gateways for subsequent breaches. Cybercriminals employ diverse techniques and types of cyberattacks . These include, but are not limited to, malware attacks, phishing schemes, ransomware threats, and denial-of-service maneuvers. A comprehensive cyberattack map would show the startling frequency and global range of these threats.

The financial ramifications of cyberattacks are deeply concerning. Cybercrime’s economic impact is continuing to soar, with estimations pointing to a staggering $10.5 trillion USD annually by 2025. For context, if cybercrime had its own economy, it would be the third-largest in the world, surpassed only by the economic powerhouses of the U.S. and China. The significant financial impact of cybercrime highlights the pressing need for stringent cybersecurity defenses for all governments, businesses, organizations and individuals.

What is a Cyberattack?

A cyberattack is an intricate, premeditated digital assault executed by individuals, collectives, or even nation-states. Recent cyberattacks have aimed to penetrate, manipulate, disrupt, or cripple digital systems, networks, and assets. The types of cyberattacks used are varied and include deploying malware, implementing phishing campaigns, instigating denial of service (DoS) campaigns, triggering ransomware episodes, and harnessing social engineering to manipulate individuals. These are just a few of the numerous tactics in the ever-expanding arsenal brought to bear by cyber criminals.

Cyberattacks can stem from a variety of motives. Many are driven by the allure of financial gains, while other cyberattacks, especially in recent years, are geared towards espionage, influencing political landscapes, or even spawning widespread mayhem. Cyberattacks typically target vulnerabilities or weaknesses present in software or hardware, or exploit inherent human susceptibilities. They aim to outmaneuver the security barriers that organizations leverage to prevent attacks so they can exfiltrate data, jeopardize data confidentiality, integrity, and availability to its owners and holders, and in the process, erode the trust placed in digital organizations and structures.

The aftermath of these types of cyberattacks can be severe. Targets might grapple with significant financial costs, damage to their public image, breaches of the personal privacy rights of customers, employees and users, and in the case of attacks on government, public sector and vital infrastructure, dangerous threats to national safety. As technological boundaries continually evolve to safeguard against known attack vectors and methods, attackers likewise vary and innovate their attack methodologies to increase their sophistication and capabilities.

How do Cyberattacks Happen?

At the core, a cyberattack is a deliberate exploitation of technology networks, systems, or data. The perpetrators, who range from individual hackers to sophisticated criminal organizations and even state-sponsored entities, exploit vulnerabilities in digital systems for various motives such as financial gain, espionage, or sabotage.

Myriad mechanisms are used in the execution of cyberattacks. Some attackers use sophisticated malware, while others might rely on simple yet effective phishing schemes to trick individuals into revealing sensitive information. In recent years, many cyberattacks have deployed ransomware to effectively block organizations from accessing their data unless a ransom is paid. Double ransomware attacks go a step further, threatening to expose confidential or embarrassing data unless the ransom is paid. In many cases, cybercriminals will sell data as well as demanding ransom to further increase profitability of the cyberattack. Denial of service attacks, another common type of attack, flood a network with traffic to disrupt service. These cyberattacks can be particularly harmful to businesses.

As a vast networks with extensive reach into almost every business and organization, the internet serves as a cyberattack launchpad for a multitude of threat actors that are driven by diverse motives. Cyberattacks are most often perpetrated by the following categories of individuals, who choose to conduct cyberattacks for a few primary reasons, using diverse attack strategies.

Nation-State Actors

Operating at the behest of governments, politically motivated entities are among the most organized and potentially devastating perpetrators of cyberattacks. Their motivations may range from espionage and sabotage to exerting political influence on a global stage. Often equipped with state-of-the-art tools and a vast array of resources, nation-state actors are adept at launching cyberattacks that exploit software and hardware vulnerabilities. Recent attacks have also leveraged supply chains. Nation-state actors are often in for the long haul, establishing persistence and lurking within systems, undetected, in order to gather information before taking action that is likely to reveal their presence.


Financial gains are the predominant drivers of these actors. Through tactics like ransomware, phishing, or fraud schemes, cybercriminals seek to extract money or valuable data from their targets. Credential theft is likewise a common goal, since they can be used to gain further access and can also be profitably sold to other threat actors. While criminals’ methods might not always be as advanced as nation-state actors, recent cyberattacks indicate that their aggressive pursuit of financial rewards plays a large role in generating significant threats in the cyber landscape.


Whether motivated by vengeance, personal grievances, or financial gain, insiders present a unique challenge in the realm of cyberattack types. With intimate knowledge of an organization’s infrastructure and potential weaknesses, they can inflict significant damage, often capitalizing on privileged information to gain access to sensitive content and wreak havoc.

Cyberattack Targets: What’s at Risk?

The risk from cyberattacks, whether for individual users or multinational corporations, is vast. In this section, we examine cybercriminals’ targets and discuss the assets and data they’re hoping to find.


Every individual who is online is potentially at risk for cyberattacks. In attacks on individual users, cybercriminals target personal information, such as social security numbers, bank details, or even medical records. With the rise of social media, even personal preferences, behavioral patterns, and interpersonal relationships are lucrative targets, since such information can be used for identity theft, financial fraud, or to enhance the success of social engineering attacks.


Enterprises of all sizes represent a gold mine for cyber attackers. The data they hold may include sensitive financial records, proprietary intellectual property, and customer and employee data. Many businesses have extensive internet exposure, with VPNs, customer portals, websites and applications creating a vast and vulnerable attack surface. Yet often, they lack the comprehensive cybersecurity measures that are needed to secure their digital resources, or fail to follow best practices for maintaining the solutions they have. Breaches can result not only in financial losses but also downtime, reputational damage, legal and regulatory repercussions, and loss of customer trust.

Critical Infrastructure

Critical infrastructure like power grids, transportation networks, water supply systems, and healthcare facilities have become increasingly digitized. This increases their exposure to potential cyber threats that can have widespread and catastrophic consequences. Attacks on these systems have disrupted provision of essential goods and services, endangered lives, and created risks to national security.

Digital Assets

Assets such as cryptocurrencies or digital certificates are vulnerable to cyberattacks. If compromised, financial and reputational consequences can be substantial.

Cloud and SaaS Platforms

With increased business and government reliance on cloud computing and SaaS platforms, providers have become attractive targets for cyberattacks. Unauthorized access might expose vast quantities of data across numerous subscribers, enabling further attacks on organizations that depend on these services.

Types of Cyberattacks

As all aspects of modern life – education, government, business, healthcare, logistics, justice and more — become dependent on digital platforms and networks, understanding the many ways cyber threats manifest becomes essential. This section delves into the diverse types of cyberattacks, highlighting their nature, mechanisms, and potential repercussions. Knowledge of these threats serves as a foundation for enhancing defenses and ensuring digital safety.

Phishing Attacks

Phishing remains one of the most common types of cyberattacks, and one of the most effective. Using social engineering techniques, it involves tricking a recipient into revealing confidential information such as credentials or bank details, or downloading malware, typically through deceptive, high-pressure emails or messages that seem to be from a trusted source.

Malware Attacks

Malware represents a broad category of cyberattacks. Malware encompasses various types of malicious software, including viruses, worms, and spyware. These are designed to infiltrate, damage, or disable computers and computer systems. Some malware may establish persistence, opening and maintaining communications channels that enable external command and control (C2) of the host systems.

Ransomware Attacks

In recent years, ransomware has exploded as a one of the most prevalent types of cyberattack. In such an attack, the perpetrator encrypts the victim’s data and demands payment to unlock it. In newer, more pernicious types of ransomware attacks cybercriminals maintain leverage over organizations that have current backups by threatening to expose stolen data to pressure them to pay up and/or sell data they’ve stolen to increase financial gains. Often, the threat actors will expose or sell data despite ransom payment to increase their gains. Ransomware cyberattacks can cripple businesses with long-term shut-downs, costly remediation and restoration, loss of crucial data and revenue, and exposure to legal and regulatory penalties.

Distributed Denial of Service (DDoS) Attacks

In DDoS attacks, normal, desired web traffic is disrupted when multiple compromised systems flood the target system with internet requests, and thereby block access for legitimate users and customers.

Man-in-the-Middle (MitM) Attacks

MitM attacks occur when attackers interrupt or intercept communication between two parties to steal or manipulate the data being exchanged. This can occur during the sign-in process, with threat actors intercepting credentials or during transactions, when a cybercriminal who has penetrated a user device uses a keylogger to record credit card, account or other sensitive details; or during any communication between users and other users, or users and applications, or even between devices participating in digital processes.

The Effect of Cyberattacks on Businesses

Cyberattacks pose a significant threat to businesses, potentially leading to financial losses, reputation damage, and operational disruptions. However, organizations can significantly mitigate these risks with effective prevention, detection and response strategies.

Implementing protective technology, robust monitoring systems, training staff to recognize signs of cyber threats, and establishing clear incident response protocols are just a few ways businesses can swiftly identify and address vulnerabilities. More importantly, organizations should seek solutions that can keep cyberthreats away from vulnerable attack surfaces and block common attack vectors.

A proactive approach safeguards critical data and assets and reinforces trust among customers and stakeholders, ensuring business continuity.

Responding to recent cyberattacks is essential, but proactive defense mechanisms and best practices play an even more critical role in safeguarding an organization’s digital assets. This section provides recommendations and industry-standard approaches to prevent cyberattacks, ensuring a robust defense for systems and data.

1. Adopt the Zero Trust Model:

The Zero Trust philosophy operates on the premise of “never trust, always verify.” Instead of relying on traditional perimeter defenses, the Zero Trust approach ensures every access request, whether from inside or outside the organization, is robustly authenticated, authorized, and encrypted before granting access.

2. Implement Secure Access Service Edge (SASE):

SASE is a security framework that integrates network security and wide area networking capabilities into a single cloud-based service. By providing secure and streamlined access to cloud services, applications, and resources, SASE ensures consistent security policies, especially in the face of varied types of cyberattacks, irrespective of the user’s location

3. Leverage Network Segmentation:

Network segmentation involves dividing a network into smaller segments or subnetworks. This not only enhances performance but, more crucially, restricts potential breaches to a specific segment, preventing the spread of threats across the entire network.

4. Regular Security Training:

Educating employees about the latest threats, phishing tactics, and safe online habits can significantly reduce the risk of human-induced breaches from different types of cyberattacks. Regular training sessions can empower the workforce to become the first line of defense against potential cyber threats.

5. Regularly Update Software and Systems:

Cybercriminals often exploit vulnerabilities in outdated software. Ensuring that all systems, applications, and software are updated with the latest patches, is a straightforward yet effective way to bolster security against the various types of cyberattacks.

6. Employ Multi-Factor Authentication (MFA):

MFA requires users to provide two or more verification factors to gain access to a resource. By adding an additional layer of authentication, it becomes significantly harder for attackers to breach accounts, even if they obtain passwords.

7. Backup Data Regularly:

Regular backups ensure that, in the event of a ransomware attack or data breach, critical information can be restored. Backups should be stored both on-premises and in a secure cloud environment, ensuring data integrity and availability.

Cyberattack Maps

When cyberattacks are a persistent threat, having an instantaneous and comprehensive understanding of these attacks through a cyberattack map becomes paramount.
