Evolving Cyber Threats in 2025: What Organizations Must Watch and Do Next

The Main Cyber Threats Facing Businesses in 2025

Generative AI: A Double-Edged Sword

While AI tools bring productivity gains, they also empower attackers. From undetectable phishing emails and voice cloning to deepfake videos and the rise of ransomware-as-a-service (RaaS), generative AI is fuelling new attack vectors.

In just three months, deepfake-related scams resulted in more than $200 million in losses, according to Resemble AI.

State-Sponsored Cyber Warfare on the Rise

Nation-state actors, such as those in North Korea and China, continue to target critical infrastructure and global supply chains. These attacks, often rooted in espionage or ransomware, are designed to serve geopolitical goals and create widespread disruption.

The Cost of Overlooking Zero-Trust Architecture

Zero-trust principles – "always verify, never trust" – can significantly reduce lateral movement by attackers. Yet many organizations still rely on outdated network models. Without continuous authentication and microsegmentation, critical gaps remain.

Implementation may be complex, but ignoring it leaves the door open to breaches.

The Disconnect in the Boardroom

Cybersecurity risks often fail to translate into business impact at the executive level. This communication gap affects budgeting, strategy, and buy-in, leading to insufficient controls and increased vulnerability.

Phishing Attacks Get Smarter

Phishing isn’t going away. It’s getting more sophisticated. Tactics like QR-code phishing (quishing), AI-generated spear phishing, business email compromise (BEC), vishing, and smishing are becoming more personalized and harder to detect.

Telecom and IoT: Expanding the Attack Surface

The rapid expansion of connected devices, especially in telecom and IoT, has outpaced many companies’ ability to secure them. The recent M&S attack, rooted in SIM swapping, highlights how unmanaged endpoints can become easy entry points.

Ransomware Grows More Sophisticated

Double-extortion ransomware, which combines data encryption with exfiltration, is on the rise. Ransomware-as-a-service (RaaS) is cheaper and more effective than ever, thanks to AI-enhanced tools that automate many attack functions.

Supply Chain Vulnerabilities

Third-party vendors are a common entry point for attackers. The polyfill.io incident, which compromised more than 100,000 websites, underscores the importance of vetting and monitoring digital supply chains.

The Remote Work Factor

Home networks and devices often lack enterprise-grade security. Remote workers are now a primary target, highlighting the need for endpoint detection and response (EDR) across distributed teams.

Mobile Devices: The Overlooked Threat

Smartphones and tablets frequently go unpatched or lack antivirus protection. Enforcing policies around patching, device management, VPN use, and secure Wi-Fi is essential for mobile workforce security.

Advanced Persistent Threats (APTs)

These long-term, stealthy attacks, often backed by nation-states or organized crime, are difficult to detect and mitigate. A layered defence strategy that includes endpoint protection, multi-factor authentication, and employee training is key.

Cybersecurity Skills Remain in Short Supply

Open cybersecurity roles continue to outnumber qualified professionals. Upskilling, investing in training, and strengthening the talent pipeline are strategic priorities, not optional improvements.
