What is a Cyber Attack?

A cyber attack is an assault launched by cybercriminals using one or more computers against a single or multiple computers or networks. A cyber attack can maliciously disable computers, steal data, or use a breached computer as a launch point for other attacks. Cybercriminals use a variety of methods to launch a cyber attack, including malware, phishing, ransomware, denial of service, among other methods.

  • Global cyber attacks grew significantly in 2024, with the average number of attacks per week per organization increasing by 44%.
  • Education is the most affected industry, with a 75% year-over-over increase. Government and healthcare were the 2nd and 3rd most targeted industries, respectively.
  • Supply chains (including software, hardware, and semiconductor businesses) saw a dramatic increase. In particular, weekly cyber attacks on the hardware and semiconductor industry grew by 179%. This trend is driven by the integration of AI technologies and the demand for hardware.

Email remains the dominant attack vector, making up 68% of attacks. However, there was a significant increase in web-delivered attacks (32%)

Types of Cyber Attacks

While cyber attack types are typically defined by the method used to gain unauthorized access or disrupt systems, they also vary based on:

  • Motive: Financial gain, political reasons, personal motivation, etc.
  • Threat Actor: Insider or an outsider threat, individual attacker, cyber crime groups, state-sponsored actors, etc.
  • System Targeted: Customer data, payment systems, financial data, intellectual property, account credentials, etc.

The specific attack vectors or methods threat actors utilize are evolving in response to new cybersecurity strategies. Plus, new multi-vector attacks offer advanced entry points by combining different methods. The most common attack vectors you need to know are discussed below.

#1: Malware

Malware, or malicious software, is a broad term for programs that are intentionally designed to damage computer, network, or server operations. This could be through:

  • Taking control of system functionality
  • Preventing operations
  • Gaining unauthorized access to steal or remove data

Malware threats typically reproduce to spread across connected systems, giving the attacker further access to do more damage. It can be delivered in multiple ways, including phishing and software vulnerabilities. It can also facilitate many other attacks such as ransomware and Distributed Denial of Service (DDoS).

Common malware threats include:

  • Trojan Horse: Tricking users into installing malware disguised as a legitimate program.
  • Spyware: Malware that covertly runs on the user’s system to obtain sensitive data such as login credentials or financial information.
  • Scareware: Scaring victims into downloading malware using fake messages about the risks they face. This includes false cyber attack messaging that convinces a user to download malware disguised as antivirus software.
  • Worms: Replicating code with the primary purpose of spreading between systems to increase the attacker’s access and control within a network.
  • Infostealer: Infiltrates systems to steal sensitive data, primarily targeting login credentials and financial information.

#2: Ransomware

Ransomware attacks are a form of malware that infiltrates corporate networks or personal computers to encrypt data or lock users out of their own systems. The attacker withholds the data or system access, asking the victim to pay a ransom in exchange for regaining access.

This fee is commonly demanded in cryptocurrency to disguise the attacker’s identity while they receive funds.

#3: Phishing

A phishing attack is a type of social engineering attack that tricks the victim into downloading malware or revealing sensitive information like login credentials or credit card information. Social engineering attacks target users by actively deceiving them to induce a specific action rather than utilizing any form of technical “hacking” knowledge.

Phishing attacks send victims fake communications that appear to be real and from a reputable source.

These communications are commonly sent via email but can leverage other channels like text messages or social media. The fake messages will trick the victim into downloading malware through an attachment or visiting a malicious site masquerading as a legitimate site where they enter sensitive data.

Typical phishing attacks use a blanket message sent to a large number of people, hoping to trick someone into the desired action. But, other forms of phishing attacks take a much more targeted approach.

  • Spear phishing researches potential victims to produce more convincing fake messages.
  • Whale phishing is a form of spear phishing that focuses on high-value targets such as business executives.

#4: Denial of Service (DoS)

A Denial of Service (DoS) attack, also called a brute-force attack, floods a website or server with huge amounts of traffic to take it offline.

By overwhelming systems, DoS attacks prevent legitimate users from accessing services.

An extension of DoS is DDoS, utilizing many compromised devices to increase the traffic it is possible to send. This is often performed through a botnet, a large number of malware-infected devices the attacker controls. Cybercriminals may have various reasons for launching DoS attacks, including:

  • Demanding a ransom to stop the attack.
  • Political activism targeting government agencies or corporations.
  • An unethical form of competition between businesses in the same industry.
  • Cyber warfare sponsored by states to weaken their adversaries.
  • Causing chaos and disrupting services.

#5: Man-in-the-Middle (MITM)

A Man-in-the-Middle (MITM) attack is when the threat actor positions themselves between two parties (e.g., two people, a person and a server, etc.) to eavesdrop and intercept communications. The attacker can then steal sensitive data, such as login credentials.

MITM attacks often take advantage of unsecured public WiFi networks, where it is easy to intercept user data.

#6: Injection

Injection attacks exploit software vulnerabilities to input malicious code into a system. This is often injected into the system through public-facing inputs like:

  • Search bars
  • Login fields
  • API requests

Injection attacks enable the attacker to execute unauthorized commands, access data without authorization, or take over system capabilities. Common forms of injection attacks include Structured Query Language (SQL) injection and Cross-Site Scripting (XSS).

During SQL injection, an attacker inserts malicious code that enables them to reveal information from an SQL database. XSS injects malicious code into a legitimate web page so that it runs on subsequent visitors’ browsers.

#7: Zero Day Exploits

Many cyber attacks exploit vulnerabilities in software, inherent weaknesses in the code that allow threat actors to manipulate applications for their own gain.

Often, these are known vulnerabilities that have not been properly patched or protected against.

But, new vulnerabilities are also being discovered, known as zero day exploits. These have the potential to cause major cyber attacks as they offer a new way of compromising business networks before they can implement a cybersecurity response.

There is a window of time before security teams find a way to fix the issue, and organizations update their software to patch the vulnerability.

#8: Supply Chain Attacks

Modern applications utilize pre-existing code, either proprietary or open source.

This is known as the software supply chain. Hackers can infiltrate systems by exploiting vulnerabilities in the software supply chain. This includes targeting unmaintained libraries or component code that is no longer updated for the latest vulnerabilities.

#9: Cryptojacking

A form of malware that takes control of a victim’s computer resources to mine cryptocurrency.

The attacker remains hidden while hijacking system resources for their own financial gain. Cryptojacking can also infiltrate the user’s browser by running code in JavaScript.

 

5 Best Practices for Cyber Attack Prevention

Given the risk posed by these threats, organizations need a robust and structured cybersecurity response to ensure they remain protected. Best practices for cyber attack protection include:

  1. Implementing a multi-layered security strategy: You cannot rely on a single strategy with a range of cyber attack types to protect against. Security is derived from implementing a series of approaches that complement one another. Consider rigorous employee training, advanced email filtering, regular data backups, regular software updates, strict access controls based on zero trust, incident response planning, and more.
  2. Utilizing AI for cybersecurity: While AI is fueling more sophisticated cyber attacks, it also enhances prevention and detection strategies. Leveraging AI technology helps improve the quality of threat detection systems, spotting signs of attack earlier before they escalate. AI can even alert you to zero day exploits based on behavioral analysis rather than waiting for attacks to be studied and signatures to be found. Next, AI can streamline incident response and remediation to act more efficiently and effectively.
  3. Focusing on cloud security: As businesses transfer more workloads to the cloud, they must consider the new security threats they open themselves up to. With data distributed and managed across different environments, you need to implement zero trust architecture and enhanced identity management to verify users and devices. Additionally, prioritize API security and implement cloud security tools to spot misconfigurations and manage your infrastructure.
  4. Integrating security tools for visibility: With increasingly complex corporate networks being targeted by increasingly sophisticated cyber attacks, you need to understand your systems in order to protect them fully. While expanding security tool portfolios brings additional protections and capabilities, it also increases the chances of data silos and visibility gaps. Ensure you have a unified platform with comprehensive visibility into your network.
  5. Ensuring compliance for customer trust: Regulations are rapidly changing, and businesses operating across different jurisdictions must find ways to comply with complex and sometimes contradictory rules. Focus on data sovereignty and controlling your most sensitive information. Also, consider automation tools. You can streamline audits and reporting to simplify compliance and eliminate human errors.
