Top 5 Cyber Threats Likely to Evolve Worldwide in 2025

Integrating AI into business operations will likely surge in 2025. AI systems often process massive troves of sensitive data, bringing significant opportunities and technical, legal, and privacy challenges for organizations.      

Cybercriminals will also leverage AI for their own purposes. Criminals increasingly use AI to automate and scale attacks, develop adaptive malware, and conduct sophisticated social engineering schemes, such as deepfake-based phishing. These attacks will become harder to detect and defend against and require advanced threat intelligence and AI-based defenses.    

Quantum technology is a type of data processing that analyzes information and performs calculations much faster and more efficiently than traditional computers. While conventional systems could take decades to solve complex optimization problems, quantum computing can potentially solve such issues in seconds.    

Although still in its early stages, as quantum computing advances, the risk to traditional encryption methods will grow in 2025. Quantum computing will eventually break existing encryption methods and render them obsolete by exposing sensitive data to decryption by adversaries. This poses a formidable challenge to organizational data security and confidentiality, potentially exposing sensitive information and intellectual property – with significant implications for logistics, finance, drug discovery, encryption protocols, and other applications.    

The growing sophistication of diverse threat actors (TAs) and interdependence of third-party vendors will likely expose additional vulnerabilities in critical supply chains and potentially lead to more significant disruptions. The February 2024 ransomware attack on Change Healthcare, a major payment processing firm, interrupted most US pharmacy operations and reportedly exposed millions of people’s sensitive information. AI will likely escalate the frequency of supply chain attacks targeting critical infrastructure and software systems as a force multiplier. The emerging technology could enable cybercriminals to automate and scale their operations more successfully. Various physical challenges, ranging from political conflicts and economic instability to natural disasters, could exacerbate the fragility of interconnected supply chains. Such trends could make predicting and mitigating future risks even more difficult.   

Social engineering tactics will continue to grow in sophistication with the evolution of transformative technologies and data availability. Cybercriminals will likely increase their use of AI, machine learning, big data, and advanced psychological profiling techniques to create more personalized and convincing scams.    

Phishing campaigns are also more likely to become accurate, with hackers using advanced tools as catalysts for creating highly targeted and persuasive attacks. Users can also anticipate the increasing use of deepfake technology and voice synthesis, which could be used to deceive individuals more successfully. Such evolving tactics could result in greater financial losses and significant personal and organizational security challenges.    

Ransomware is malware designed to deny users or organizations access to devices, networks, or data - usually through encryption - until a ransom is paid. As digitalization increases, ransomware has and will continue to evolve through 2025 as a significant cybersecurity threat for organizations. Although any entity is a potential target, those that handle sensitive data or manage critical infrastructure are especially at risk, including financial services, healthcare providers, and government agencies, necessitating enhanced backup strategies and incident response plans.    

Cybercriminals have also modified their approach to ransomware. Triple-threat extortion has become more widespread. Criminals do not only encrypt victims' data but exfiltrate sensitive personal or commercial data and threaten to publish it online to put additional pressure on victims to pay ransom. TAs could use the exfiltrated data to conduct future social engineering tactics. Fueled by low prosecution rates and victims’ willingness to pay ransoms to recover data and salvage their organizations, ransomware incidents will almost certainly see further growth over the coming months.  

Amid evolving threats from multiple quarters, organizations need to adopt a multi-layered approach to cybersecurity, which includes administrative (policies and SOPs) and technical (firewalls, anti-virus, segmentation) controls. However, operational controls - in the form of awareness and training - continue to be the cornerstone of a robust defense strategy. Advanced technologies and stringent policies play important roles, but they are only as effective as the humans who implement and manage them. Continuous training empowers individuals to recognize, respond to, and mitigate threats, transforming employees from potential vulnerabilities into active defenders. By fostering a culture of cybersecurity awareness, a well-trained workforce, from entry-level staff to the C-suite, empowers organizations by reducing human error - the primary cause of breaches. Investing in training is the single most cost-effective way that an organization hardens its security posture against cyber threats.
