In 2025, cyberattacks have continued to grow in both frequency and scale and 2026 is unlikely to bring reprieve. Emerging technologies like agentic AI and quantum computing create new opportunities for both good guys and bad guys. But as usual, we humans are likely to be the weakest link as well as the most potent defense.
Experts say that if cybercrime were a nation in 2026, it would be the world’s third-largest economy, behind the US and China, costing businesses an estimated $20 trillion. So here are what I believe will be the biggest trends driving this unprecedented global crime wave over the next 12 months.
1. Agentic Cyber Attack And Defense
AI agents are the new frontline of the cybercrime battlefield. Capable of acting autonomously and interfacing with third-party services, they will allow attackers to carry out more sophisticated attacks, probing defenses to find weaknesses and launching evolving social engineering attempts. But they also provide defenders with powerful new options for autonomous detection and response. In 2026, this means they are the latest escalation of the cybersecurity arms race, raising the stakes for both criminals and businesses.
2. Deepfake And Synthetic Cyber Attacks
Deepfaked audio and video create new possibilities for attackers to mimic trusted individuals and access secure systems. There have already been instances of employees being tricked into transferring vast amounts of money after receiving spoofed phone calls from their boss and as the technology becomes more sophisticated and difficult to differentiate from reality, this will become a more frequent occurrence.
3. The Evolving Ransomware Threat
Attacks involving locking away vital business data and extorting money in exchange for its return continue to increase and will become more advanced in 2026. The growing availability of ransomware-as-a-service tools means even non-tech-savvy criminals can launch these attacks, and deepfake technology makes it easier to get past human defenses. On top of this, new, more anonymous cryptocurrencies make it easier to transfer, launder and spend ill-gotten gains without fear of repercussion.
4. Strengthening The Weakest Link
The weakest link in security infrastructure is usually humans. Criminals often find it’s easier to trick, bribe or blackmail people into revealing access credentials than it is to break through sophisticated technological security barriers. In response, businesses will invest more heavily in training workers to be aware of threats, running simulated social engineering attacks and building cultures of security awareness across their organizations.
5. Quantum Security
Quantum computers will take seconds to solve problems that would take today’s most powerful computers centuries, transforming science, healthcare and finance. But they also pose a serious threat to encryption that secures sensitive data and communications. Criminals are already harvesting vast quantities of data, ready for the day that quantum technology makes it readable. In 2026, the focus will be on identifying vulnerabilities and migrating to quantum-safe encryption before it’s too late.
6. Regulatory And Legislative Overhaul
Regulators and lawmakers have so far struggled to keep pace with the rapid evolution of cybercrime. This isn’t about punishing criminals (who don’t tend to obey laws anyway) but putting pressure on companies to make sure valuable customer data is protected. Measures like the US SEC’s new rules on cyber disclosure will force companies to report and document breaches, while the EU NIS2 directive will expand the obligation of businesses to implement resilience measures. Whether this will help stem the tide of data theft and extortion in 2026 remains to be seen.
7. Cyber Warfare On The Global Stage
The war in Ukraine has demonstrated that cyber attacks targeting critical infrastructure, communications networks and supply chains, as well as disinformation campaigns, are now everyday weapons of war. State-sponsored and terrorist campaigns strike at energy and healthcare systems and sow economic chaos by disrupting business and commerce. Deepfakes are widely used to embarrass politicians and undermine confidence in democratic processes. In 2026, cybercrime isn’t just about threats to individual privacy and business finances; it’s a major national security crisis. We will see governments ramp up their spending on cyber defense and research and form new alliances to counter this threat.
The Time to Prepare is Now
The cybersecurity landscape of 2026 represents a critical inflection point where emerging technologies amplify both criminal capabilities and defensive opportunities. The scale of the threat can sometimes seem overwhelming, but organizations that proactively invest in quantum-safe encryption, AI-powered defenses and human training will be best positioned to survive and thrive. The key takeaway is that the time to act is now, before the criminals gain an even greater advantage.
