- Awareness of common cyber security attacks is crucial for individuals and organisations to safeguard sensitive information and digital assets.
- By understanding how attacks operate in threatening cyber security, users can implement robust security measures, thus mitigating the risks posed by these attacks in today’s interconnected digital landscape.
In the realm of digital threats, understanding common cyber security attacks is essential for safeguarding sensitive information and digital assets. This article will explore 5 types of cyber attacks, how they occur, and their potential impacts on individuals and organisations.
1. Malware attacks
Malware, short for malicious software, refers to any software intentionally designed to cause damage to a computer, server, client, or computer network. It typically occurs through infected email attachments, malicious websites, or compromised software downloads. Common types of malware include viruses, worms, Trojans, ransomware, and spyware.
Take viruses and spyware as an example. Viruses replicate themselves by attaching to clean files and spreading across systems, often causing data loss or system damage. Spyware silently gathers sensitive information, such as passwords and financial data, and transmits it to attackers.

The major ways against malware involve using antivirus software, keeping software up to date, and exercising caution when browsing or downloading content online.
2. Phishing attacks
By masquerading as a trustworthy entity, phishing attacks involve tricking individuals into disclosing sensitive information, such as passwords or credit card numbers. Attackers often use spoofed emails, fake websites, or social engineering tactics to deceive victims, which then leads to identity theft, financial loss, or unauthorized access to sensitive information.
In a typical phishing scenario, an attacker sends an email posing as a legitimate organisation, such as a bank, requesting the recipient to click on a link and provide personal information. To mitigate phishing attacks, users should verify the authenticity of emails and websites, avoid clicking on suspicious links, and enable two-factor authentication.
3. Denial-of-Service (DoS) attacks
Denial-of-Service (DoS) attacks aim to disrupt normal traffic of a targeted server, service, or network, rendering it inaccessible to legitimate users. Attackers overwhelm the target with a flood of traffic or malicious requests, causing a slowdown or complete shutdown of services. DoS attacks can impact businesses by causing downtime, loss of revenue, and damage to reputation.
Mitigating DoS attacks involves implementing network security measures, such as firewalls and intrusion prevention systems (IPS), and using traffic filtering techniques to distinguish legitimate traffic from malicious requests.

4. Man-in-the-Middle (MitM) attacks
Man-in-the-Middle (MitM) attacks occur when an attacker intercepts communication between two parties, such as between devices on a network. The attacker can eavesdrop on the communication, manipulate data, or inject malicious content without either party’s knowledge. MitM attacks are often carried out on insecure public Wi-Fi networks or through compromised routers.
Through the use secure communication channels, such as encrypted protocols like HTTPS, and employ digital certificates to verify the authenticity of websites, this type of attack can be mitigated. Besides, implementing strong authentication mechanisms can also help detect and prevent MitM attacks.
5. Social engineering attacks
In social engineering attacks, attackers use deception, persuasion, or impersonation tactics to gain the trust of their victims, exploiting human psychology to manipulate individuals into divulging sensitive information. Common social engineering techniques include pretexting and baiting.
Pretexting involves creating a fabricated scenario to trick victims into disclosing information or performing actions. Baiting offers something enticing, such as a free download, to lure victims into clicking on malicious links or downloading malware.
Educating users about social engineering tactics and conducting regular security awareness training help defend against social engineering attacks. Additionally, implementing multi-factor authentication and maintaining a culture of security awareness can reduce the likelihood of falling victim to these tactics as well.
