AI Systems Under Siege: Every Organization Targeted in Past Year, Unit 42 Finds A new report from Palo Alto Networks’ Unit 42 reveals a stark reality: every organization surveyed has faced at least one attack on its AI systems in the past year. The findings, derived from a survey of over 2,800 participants across 10 countries—including the U.S., UK, Germany, Japan, and India—highlight a growing and systemic vulnerability in AI security, with cloud infrastructure at the heart of the problem. Conducted between September 29 and October 17, 2025, the research underscores that AI security cannot rely on reactive measures. Instead, organizations must adopt a proactive, scientific approach to safeguarding AI systems, given their complexity and critical applications. The report emphasizes that AI security is inherently tied to cloud infrastructure, where most AI workloads—data storage, model training, and application deployment—reside. Cloud platforms like AWS, Microsoft Azure, and Google Cloud, while enabling AI scalability, also present prime targets for cyberattacks. Exploitable weaknesses in cloud security can lead to unauthorized access, data theft, or operational disruptions. Traditional security measures often fall short in addressing the unique challenges of AI, such as securing data pipelines, managing identities, and protecting cloud-hosted workloads. The State of Cloud Security Report 2025 argues that the only effective defense is a holistic approach to cloud security, treating it as foundational to AI protection. This includes enforcing strong policies, encryption standards, regular audits, and isolating AI workloads from cloud vulnerabilities. As AI integrates deeper into sectors like healthcare, finance, and autonomous systems, the stakes rise—breaches could compromise sensitive data, disrupt services, or even endanger lives. Emerging threats, such as adversarial attacks designed to manipulate AI models, further complicate the landscape. The report calls for collaboration between cloud providers, AI developers, and security teams to build robust frameworks and real-time threat detection tools. The future of AI security hinges on securing the cloud infrastructure that powers it, ensuring resilience against an evolving threat landscape.
