by Sandor Fulop

What are Cyber Security Threats?

Cybersecurity threats refer to potential risks and dangers to computer systems, networks, and data that arise from malicious actors or unintended events. Cyberattacks across the board are rising with the increased level of digitalisation of daily life. In 2023, organisations in the UAE saw a rise in the number of phishing attacks, according to a report by Proofpoint. At least 92% of surveyed businesses reported experiencing an attack, up from 86% the previous year. A particularly concerning statistic from the report is 86% of adults admitted to engaging in risky security behaviour such as clicking suspicious links and sharing passwords, highlighting the need for UAE businesses to train employees and enforce security policies in their businesses. It’s crucial that organisations consider the following when creating their cybersecurity strategy:   

1. Confidentiality: Preventing unauthorised access to sensitive information, such as personal data, financial records, and intellectual property, helps maintain confidentiality. 
2. Integrity: Safeguarding data from tampering, alteration, or corruption preserves its accuracy and reliability.
3. Availability: Protecting systems and networks from disruptions ensures that services and resources remain accessible to authorised users when needed.
4. Trust: Strengthening cybersecurity measures fosters trust among users, customers, and stakeholders, enhancing the reputation and credibility of organisations.
5. Compliance and Legal Obligations: Many industries and jurisdictions have regulations and standards pertaining to data protection and cybersecurity. Understanding and mitigating threats are essential for compliance and avoiding legal repercussions.
6. Financial and Reputational Impact: Cybersecurity incidents can result in financial losses, operational disruptions, and reputational damage. Mitigating threats helps minimise these risks and their associated costs. 

Top 15 Cybersecurity Threats to Watch Out For

Being aware of the main types of cyber threats is imperative when trying to safeguard your organisation from cyberattacks.  

1. Malware

Malware is any software designed to disrupt, damage, or gain unauthorised access to computer systems. Examples include viruses, worms, trojans, ransomware, and spyware. Malware can cause data corruption, theft, and system shutdowns.   

Example: 

A hospital's computer systems are infected with a type of malware called ransomware. This malware encrypts patient records and demands payment for their release. The hospital is unable to access critical medical information until the ransom is paid, affecting patient care and hospital operations.   

2. Phishing Attacks

Phishing is a deceptive technique used to trick individuals into divulging sensitive data such as passwords, credit card details, or other personal data. It often involves fraudulent emails, websites, or messages posing as legitimate entities. 

Example: 

An employee at a financial institution receives an email that appears to be from their supervisor, requesting sensitive client data. The email contains a link to a fake website where the employee is tricked into entering the information. This results in a data breach and potential financial fraud.  

3. Ransomware

Ransomware is a type of malware that encrypts files or locks systems, demanding a ransom payment (often in cryptocurrency) for their release. It can severely disrupt business operations and lead to financial losses. 

Example: 

A small business's computer network is infected with ransomware, encrypting important business files. The attackers demand a cryptocurrency payment in exchange for the decryption key. The business faces the dilemma of paying the ransom or losing access to critical data.  

4. Insider Threats

Insider threats involve individuals within an organisation misusing their access privileges to steal data, sabotage systems, or engage in other malicious activities. They can be challenging to detect and prevent. 

Example: 

A disgruntled employee at a technology company uses their access privileges to steal proprietary code and sell it to a competitor. The theft leads to significant losses for the company and legal consequences for the employee.  

5. Distributed Denial of Service (DDoS) Attacks

DDoS attacks involve overwhelming a system or network with excessive traffic, making it inaccessible to legitimate users. These attacks can disrupt business operations and services. 

Example: 

An online gaming platform experiences a distributed denial of service attack, causing its servers to crash due to the overwhelming volume of traffic. Users are unable to access the platform, leading to loss of revenue and reputational damage.  

6. Man-in-the-Middle Attacks

In a man-in-the-middle attack, a hacker intercepts and potentially alters communications between two parties. This can lead to unauthorised access to sensitive information such as passwords and financial data. 

Example: 

A public Wi-Fi network is compromised by a hacker who intercepts and alters communication between users and the internet. Users may unknowingly share sensitive information, such as passwords and credit card details, with the attacker.  

7. SQL Injection

SQL injection attacks target databases by inserting malicious SQL statements into user inputs, allowing attackers to manipulate or retrieve data. These attacks can lead to data breaches and loss of sensitive information. 

Example: 

A hacker exploits a vulnerable website's search bar by inserting a malicious SQL query. This allows the hacker to access and manipulate the website's database, resulting in a data breach of customer information.  

8. Zero-Day Exploits

Zero-day exploits take advantage of vulnerabilities in software or hardware that are unknown to the vendor and for which no patch is available. Attackers exploit these vulnerabilities before they are discovered and fixed. 

Example: 

A hacker discovers a zero-day vulnerability in a popular software application and uses it to gain unauthorised access to users' devices. The software company is unaware of the vulnerability, leaving users exposed until a patch is released.  

9. Social Engineering

Social engineering involves manipulating individuals into performing actions or revealing confidential information. Techniques include phishing, baiting, pretexting, and tailgating. 

Example: 

An attacker poses as an IT support technician and calls an employee, convincing them to install a malicious software update. The employee unknowingly allows the attacker access to the organisation's network.  

10. Advanced Persistent Threats (APTs)

APTs are sophisticated, long-term attacks that target specific organisations or individuals to steal data or disrupt operations. They often involve a combination of malware, social engineering, and other tactics. 

Example: 

A state-sponsored hacking group targets a large corporation for intellectual property theft. They use sophisticated techniques such as spear phishing, malware, and zero-day exploits to remain undetected for an extended period while stealing sensitive data. 

11. Botnets 

Botnets are networks of infected devices controlled remotely by a hacker, often used for large-scale cyberattacks such as DDoS attacks, spam campaigns, and other malicious activities. 

Example: 

An attacker builds a botnet of infected computers and uses them to send out large volumes of spam emails containing malicious links or attachments. The botnet can also be used to launch DDoS attacks.  

12. Supply Chain Attacks 

Supply chain attacks target the interconnected network of suppliers and partners to compromise software, hardware, or services before they reach their final destination. These attacks can have widespread impacts. 

Example: 

An IT management company experiences a major supply chain attack when attackers compromise their Orion software updates. The attackers insert malicious code into the updates, allowing them to infiltrate numerous organisations and government agencies that use the software. 

13. Cryptojacking 

Cryptojacking involves using a victim's computer or network to mine cryptocurrency without their knowledge or consent. This can lead to increased energy costs and reduced system performance. 

Example: 

Attackers inject cryptomining scripts into websites, allowing them to mine cryptocurrency using the computing power of visitors' devices. Users experience slow performance while their devices are secretly used to generate cryptocurrency for the attackers.  

14. Fileless Malware

Fileless malware resides in memory or other non-file system areas, making it difficult to detect. It then leverages legitimate system processes to carry out attacks, such as stealing data or executing malicious code. 

Example: 

Attackers use legitimate scripting languages such as PowerShell to execute malicious code directly in memory, bypassing traditional file-based security measures. The threat actors then carry out data theft or lateral movement within a network. 

15. IoT Vulnerabilities

Internet of Things (IoT) devices, such as smart home appliances and industrial sensors, often have weak security measures. These vulnerabilities can be exploited to gain unauthorised access or control over connected devices and networks. 

Example: 

A smart home security camera is hijacked by attackers, and they gain unauthorised access to an individual's home network. This allows them to spy on residents or launch attacks on other devices from inside the home network.
