Top 10: Biggest Cyber Threats
Cybersecurity has evolved dramatically since the 1970s, when the first antivirus software emerged to combat early computer worms.
Today, the industry faces unprecedented challenges as cyber threats grow in sophistication and scale.
Recent incidents, such as the ransomware attack on NHS Scotland and the SolarWinds supply chain breach, highlight the vulnerability of critical infrastructure and corporate networks.
Now, the industry's focus has shifted towards developing AI-driven solutions, implementing zero-trust architectures and addressing the cybersecurity skills gap
As nation-state actors increasingly engage in cyber espionage and attacks, international cooperation has become crucial in combating these threats.
Here at Cyber Magazine, we highlight some of the Top 10 biggest global security threats to date.
10. Supply Chain Attacks
Supply chain attacks compromise software or hardware before they reach the consumer.
These attacks target vulnerabilities in an organisation's network of suppliers and partners to compromise the primary target, aiming to infiltrate secure systems by exploiting trust relationships between businesses, meaning that supply chain attack threats extend to organisations of all sizes, potentially impacting entire industries.
Companies that specialise in supply chain attacks, are cybersecurity companies like Palo Alto Networks that focus on defending against these threats.
Notable incidents include the SolarWinds attack, which affected numerous government agencies and corporations.
Gartner, a research and advisory company focusing on technology and business insights, predicts that by 2025, 45% of organisations worldwide will have experienced attacks on their software supply chains.
The complexity of modern supply chains makes these attacks particularly challenging to detect and mitigate.
9. Man-in-the-Middle (MitM) Attacks
MitM attacks in cybersecurity involve intercepting communications between two parties to steal or manipulate information to eavesdrop or manipulate data.
This threat aims to compromise data integrity and confidentiality, affecting individuals and organisations across sectors.
Companies like Cisco, a technology company and Symantec, who focus on cybersecurity software, offer solutions to detect and prevent MitM attacks.
While ethical hacking firms may use MitM techniques for security testing, malicious actors exploit these methods for financial gain or espionage.
A study by IBM, a multinational technology company, found that MitM attacks accounted for 35% of exploits observed in cloud environments.
The emergence of quantum computing also poses new challenges for encryption methods traditionally used to thwart MitM attacks.
8. Distributed Denial of Service (DDoS) Attacks
DDoS attacks overwhelm target systems with traffic from multiple sources, aiming to disrupt services and cause downtime.
These attacks threaten organisations across sectors, potentially leading to financial losses and reputational damage.
However, cloud security companies like Cloudflare and Akamai specialise in DDoS mitigation.
Additionally, Google's Project Shield is a free service that offers free DDoS protection to news sites and human rights organisations, highlighting the broader societal impact of these attacks.
While typically used maliciously, some cybersecurity firms also employ controlled DDoS techniques for stress testing.
The rise of IoT botnets has amplified DDoS threats, with Cisco reporting a 776% increase in DDoS attacks exceeding 100 Gbps from 2019 to 2020.
DDoS attacks continue to disrupt services and can serve as a smokescreen for more invasive attacks.
7. Malware
Various forms of malware, including viruses, spyware and trojans, remain a persistent threat to cybersecurity.
Malware, short for malicious software, encompasses various types of harmful programmes designed to infiltrate and damage computer systems.
While primarily used by cybercriminals, some nation-states have deployed sophisticated malware for espionage.
It aims to steal data, disrupt operations or gain unauthorised access, posing threats to individuals, businesses and governments.
Trend Micro's research reveals a 55% increase in fileless malware detections in 2023, highlighting the evolving nature of these threats.
Microsoft's Digital Defense Report importantly notes that ransomware remains the most prevalent type of malware, with attacks becoming increasingly targeted.
Cybersecurity companies like McAfee and Kaspersky specialise in malware detection and prevention.
6. Insider Threats
Insider threats from within an organisation, whether accidental or malicious, continue to be a significant concern.
These type of threats in cybersecurity involve risks posed by individuals within an organisation who have access to sensitive information, aiming to exploit internal knowledge for personal gain, sabotage or unintentional data breaches.
Companies of all sizes face this risk, with potential for severe financial and reputational damage.
Yet firms like CyberArk and Proofpoint specialise in insider threat detection and prevention.
While insider attacks are typically associated with disgruntled employees, Verizon's 2023 Data Breach Investigations Report found that 74% of insider incidents were due to human error rather than malicious intent.
IBM Security's Cost of Insider Threats Global Report 2023 revealed that the average cost of insider incidents rose to US$15.4m per organisation.
5. Advanced Persistent Threats (APTs)
APTs are sophisticated, long-term cyber campaigns targeting specific organisations or sectors, aiming to maintain covert access to systems, often for espionage or data theft.
These complex, stealthy attacks aimed at specific targets can remain undetected for long periods, making them particularly dangerous.
These threats primarily target government agencies, defence contractors and high-value industries.
Cybersecurity firm FireEye specialises in APT detection and response, alongside nation-states being known to deploy APTs for geopolitical advantage.
The Mandiant M-Trends 2023 report reveals that the median dwell time for APTs decreased to 21 days in 2022, indicating improved detection capabilities.
4. Internet of Things (IoT) Attacks
Security services companies like Palo Alto Networks and Fortinet focus on IoT security solutions.
While primarily used by cybercriminals, some security firms employ controlled IoT attacks for vulnerability testing.
With the proliferation of smart devices, IoT attacks are becoming increasingly common. Experts predict that over a quarter of all cyberattacks against businesses will be IoT-based by 2025.
IoT attacks target connected devices, exploiting vulnerabilities to gain unauthorised access, steal data or disrupt operations.
These threats impact industries adopting IoT technologies, from smart homes to industrial systems.
Gartner predicts that by 2025, 70% of IoT deployments will use edge computing for data collection and processing, expanding the attack surface.
3. Cloud Vulnerabilities
Cloud vulnerabilities have increased 150% in the last five years, posing significant risks as more businesses rely on cloud services.
Common vulnerabilities include misconfigurations, insecure APIs, and poor access controls.
Cloud vulnerabilities are weaknesses in cloud computing systems that cybercriminals can exploit to gain unauthorised access, steal data or disrupt services.
These threats pose risks to organisations of all sizes, potentially leading to data breaches and financial losses.
However, major cloud providers like Amazon Web Services, Microsoft Azure and Google Cloud Platform focus on mitigating these vulnerabilities.
Yet, IBM reports that cloud-based breaches cost companies an average of US$4.8m to recover.
Cloud vulnerabilities remain a significant concern as businesses increasingly rely on cloud services for their operations.
2. Ransomware Attacks
Ransomware attacks continue to be a major threat, with high-profile incidents like the Colonial Pipeline attack demonstrating their potential impact.
Ransomware attacks in the cyber industry are malicious software-based assaults that encrypt an organisation's data, demanding payment for its release.
These attacks aim to extort money from victims by disrupting operations and threatening data exposure.
The impact of Ransomware poses a significant threat to businesses of all sizes, with manufacturing and financial sectors particularly targeted.
For example, in Q2 2024, industrial organisations faced a surge in attacks, with ransomware-as-a-service cybercrime groups like LockBit, Cl0p and BlackBasta leading the charge.
Cybersecurity firms such as Sophos and Dragos report that two-thirds of manufacturing organisations experienced ransomware attacks in 2023, with average ransom payments reaching US$2.4m.
However major cloud providers like Amazon Web Services and Microsoft Azure focus on mitigating these threats, while companies like Check Point Software offer specialised prevention solutions.
1. Social Engineering and Phishing
Social engineering and phishing in cybersecurity exploit human psychology to gain unauthorised access to systems or data.
These techniques aim to manipulate individuals into divulging sensitive information or performing actions that compromise security.
The threat lies in their ability to bypass technical defences by targeting the human element. Organisations of all sizes face risks, with employees at every level vulnerable to sophisticated attacks.
Cybersecurity company Proofpoint and phishing detection company, Cofense, specialise in combating these threats, offering solutions to protect businesses and individuals.
Recent research by telecommunications and technology company, Verizon, found that 74% of breaches involved the human element, highlighting the persistent danger of social engineering tactics in the 2023 Data Breach Investigations Report.
However, social engineering remains one of the most dangerous hacking techniques, with phishing being a primary method.
Over 75% of targeted cyberattacks start with an email.
