Digital technology is at the center of everything we do, from online shopping to managing sensitive data at work. While technology makes life more convenient, it also opens doors for cybercriminals to exploit vulnerabilities.
First written as a 2025 outlook and refreshed in October 2026: those threats did not stay hypothetical. In 2025 ransomware attacks rose roughly 50% year over year (Chainalysis; NCC Group), and the FBI recorded 22,364 AI-related crime complaints with $893 million in reported losses. 2026 industry threat reports — Health-ISAC, ISACA, Samsung SDS — still rank the same categories below as the top concerns. Staying informed about these threats is crucial for individuals and organizations alike to stay one step ahead.
Update (October 2026): This guide was originally published as a 2025 threat outlook. The predictions below have been checked against what actually happened in 2025 — and what 2026 threat reports are still flagging as top concerns.
This article walks you through the top emerging cyber threats of 2025 and into 2026, and what they mean for you. Let’s take a look.
AI-Powered Cyberattacks
Artificial intelligence (AI) has been a game changer in cybersecurity—for both defense and attack. In 2025, those predictions proved correct. BlackFog’s 2025 State of Ransomware report documented the first large-scale AI-enabled attacks — attackers hijacked an AI model to autonomously perform reconnaissance, exploitation, and data theft. Meanwhile ISACA research finds AI-driven social engineering is the cyber threat tech professionals most expect to face in 2026 (63% of respondents). AI-driven attacks are becoming more sophisticated year over year. These attacks are faster and more targeted than ever, leveraging AI to study vulnerabilities, mimic human behavior, and deploy attacks automatically. Phishing emails, for example, are now generated by AI to appear incredibly convincing, making it harder to detect fraud.
AI-powered malware is another rising concern. Attackers can program malware to evolve based on the environment it infiltrates, bypassing traditional security systems with ease. This poses a significant threat to businesses and individuals who rely on conventional antivirus software.
With these advanced attacks on the rise, cybersecurity professionals are in high demand. For those looking to play a proactive role in defending against such threats, an online masters in intelligence and security studies offers a pathway to gain the skills and expertise needed to analyze, mitigate, and prevent AI-powered cyberattacks. Programs like these focus on understanding the latest in cybersecurity threats while preparing professionals to address them effectively.
Deepfake Technology in Cybercrime
Deepfake technology is no longer just a gimmick for creating entertaining videos—it’s becoming a weapon for cybercriminals. By manipulating images, audio, or video, deepfakes can create convincing yet entirely false representations of people. By 2025–2026, cybercriminals were exploiting this technology at scale — for financial fraud, executive impersonation, and misinformation. The FBI’s 2025 Internet Crime Report logged 22,364 AI-related complaints and $893 million in reported losses, and industry analysis put deepfake-driven fraud losses at more than $1.5 billion in the first nine months of 2025 alone.
Imagine receiving a video call from a trusted colleague asking for sensitive information, only to discover later it was a deepfake. Scenarios like these are not science fiction; they’re becoming a reality. Fraudulent deepfakes have already caused harm in financial and political contexts, and the potential for misuse is only growing.
Organizations need to invest in technologies that detect and counter deepfakes. At the same time, individuals must remain vigilant, double-checking any requests that seem unusual, even if they appear to come from a trusted source.
The Expansion of Ransomware-as-a-Service (RaaS)
Ransomware is one of the most notorious cyber threats, and it’s evolving into a service model. In 2025, RaaS grew into the dominant extortion model. Chainalysis tracked nearly 8,000 ransomware leak events in 2025 — up 50% from 2024 — while identifying 57 new ransomware groups and 27 new extortion groups. NCC Group counted 7,874 ransomware incidents in 2025 (up 50%), with industrial and manufacturing firms the hardest-hit sector and the U.S. accounting for more than half of all attacks. The silver lining: on-chain ransom payments fell 8% to $820 million as fewer victims paid. RaaS operates much like a subscription service: for a fee, attackers gain access to ready-made ransomware kits they can use to target victims.
The impact of ransomware attacks is staggering, especially on small businesses and critical services like hospitals. Imagine a healthcare provider unable to access patient records because of a ransomware attack. These disruptions can have life-threatening consequences.
To combat RaaS, organizations need to strengthen their defenses with regular data backups, employee training, and advanced threat detection tools. Governments also need to crack down on RaaS operators by collaborating across borders to dismantle these operations.
Threats to Critical Infrastructure
Critical infrastructure, such as power grids, transportation systems, and water supplies, is becoming a prime target for cybercriminals. A successful attack on these systems could disrupt entire cities or even countries. That rise materialized through 2025 and into 2026. In the summer of 2026, coordinated intrusions compromised water utility facilities across multiple U.S. states, attributed to Iranian-linked actors (Dark Reading, September 2026) — while ransomware crews kept hitting physical production lines, including an attack that froze U.S. production at a major dairy company for 11 days. Geopolitical tensions and the increasing interconnectedness of these systems remain the drivers.
Attacks on infrastructure are particularly alarming because they can endanger public safety. Imagine a city-wide blackout caused by hackers or a contaminated water supply due to a cyberattack on treatment facilities. These are not hypothetical scenarios—they have already happened in isolated cases.
Governments and private organizations need to collaborate on securing infrastructure, investing in advanced technologies, and conducting regular security audits to identify vulnerabilities. Public awareness and preparedness also play a critical role in minimizing the impact of such attacks.
Quantum Computing’s Role in Breaking Encryption
Quantum computing is a revolutionary technology with the potential to solve complex problems much faster than traditional computers. While this has many positive applications, it also poses a serious cybersecurity threat. Quantum computers can break current encryption methods, which form the backbone of online security.
If quantum computing falls into the wrong hands, encrypted data like financial transactions, government communications, and personal information could be compromised. As quantum technology becomes more accessible, the need for quantum-resistant encryption methods becomes urgent.
The transition is now officially underway: NIST finalized its first post-quantum encryption standards in August 2024, and migration has begun across industry and government. The urgent near-term danger is not a working cryptographically-relevant quantum computer but “harvest now, decrypt later” — adversaries stealing encrypted data today to unlock it once quantum hardware matures. Organizations must start (and in many cases accelerate) transitioning to encryption standards that are resistant to quantum attacks. Governments and industry leaders should prioritize research and development in this area to protect against future threats.
Supply Chain Attacks
Supply chain attacks are becoming one of the most effective methods for cybercriminals to infiltrate large organizations. In this type of attack, hackers target a smaller vendor or supplier to gain access to their larger partners. The infamous SolarWinds attack, for example, demonstrated how a single compromised software update could impact thousands of organizations worldwide.
That prediction held. Throughout 2025, supply-chain incidents repeatedly showed that a provider’s security is only as strong as its weakest vendor link — breaches via third parties affected millions of records and prompted an industry-wide reassessment of third-party risk. Health-ISAC’s 2026 threat landscape report now lists third-party breaches among the top five concerns for the year. To mitigate these risks, businesses need to vet their suppliers carefully and implement strict security protocols. Multi-layered defenses and frequent software audits are important in identifying and addressing vulnerabilities in the supply chain.
IoT and Smart Device Vulnerabilities
The Internet of Things (IoT) continues to expand, with more devices connected to the internet than ever before. Smart home devices, wearable tech, and connected appliances are incredibly convenient, but they also create new security risks. Many IoT devices have weak security protocols, making them easy targets for hackers.
For example, a poorly secured smart thermostat could serve as an entry point for attackers to access a homeowner’s network. On a larger scale, compromised IoT devices in businesses or factories could disrupt operations or leak sensitive data.
To secure IoT devices, users should update firmware regularly, use strong passwords, and limit the number of devices connected to critical networks.
Cyber threats are evolving at an unprecedented pace, and 2026 continues to bring new challenges. While these threats may seem challenging, they also present opportunities for innovation and collaboration. By staying informed and adopting proactive measures, individuals and organizations can mitigate the risks and build a more secure digital future. Together, we can rise to meet the challenges of a connected world.
