Cloud threats in 2026: how AI will reshape cybersecurity

AI is having a huge impact on every industry, and cybersecurity is no exception. Yandex Cloud experts analyzed the trends of 2025 and tried to predict what the cloud security landscape will look like in 2026. The central question: how will threats to cloud environments change, and how should organizations prepare?

In recent years, cloud technology has become an integral part of doing business. It delivers flexibility, scalability, and cost savings. But alongside those benefits, the cloud also brings new risks. Attackers constantly look for ways into cloud infrastructure to reach sensitive data or disrupt services. AI only complicates the picture, handing new tools to defenders and attackers alike.

One of the key trends is AI-driven attack automation. Attackers can use machine learning to find vulnerabilities, build phishing campaigns, and evade security systems. AI can also be used to create more sophisticated malware that is harder to detect. On the other hand, AI can also help defend cloud environments. Machine learning-based intrusion detection systems can automatically spot anomalies and suspicious activity and stop attacks before they land.

Data protection in the cloud is another important area. Organizations need to encrypt data, control access, and prevent leaks. It's important to understand that responsibility for data security is shared between the cloud provider and the organization itself. Companies should choose reliable providers that offer a high level of security and roll out their own protective measures as well.

Which specific threats will matter most in 2026? We will likely see more supply chain attacks aimed at compromising cloud services. We can also expect a rise in social engineering attacks designed to steal the credentials of cloud service users. And traditional threats such as software vulnerabilities and security misconfigurations shouldn't be forgotten.

In short, 2026 will bring new challenges for cloud security. AI creates both new threats and new opportunities for defense. Organizations need to be ready for these changes and take steps to strengthen their cloud security. That means deploying modern security systems, training staff, and running regular security audits. Only then can they reliably protect their data and keep their business running in the cloud.
