“OS Agents can complete tasks autonomously and have the potential to significantly enhance the lives of billions of users worldwide,” the researchers note. “Imagine a world where tasks such as online shopping, travel arrangements booking, and other daily activities could be seamlessly performed by these agents.”

The most sophisticated systems can handle complex multi-step workflows that span different applications — booking a restaurant reservation, then automatically adding it to your calendar, then setting a reminder to leave early for traffic. What took humans minutes of clicking and typing can now happen in seconds, without human intervention.

Why security experts are sounding alarms about AI-controlled corporate systems

For enterprise technology leaders, the promise of productivity gains comes with a sobering reality: these systems represent an entirely new attack surface that most organizations aren’t prepared to defend.

The researchers dedicate substantial attention to what they diplomatically term “safety and privacy” concerns, but the implications are more alarming than their academic language suggests. “OS Agents are confronted with these risks, especially considering its wide applications on personal devices with user data,” they write.

The attack methods they document read like a cybersecurity nightmare. “Web Indirect Prompt Injection” allows malicious actors to embed hidden instructions in web pages that can hijack an AI agent’s behavior. Even more concerning are “environmental injection attacks” where seemingly innocuous web content can trick agents into stealing user data or performing unauthorized actions.

Consider the implications: an AI agent with access to your corporate email, financial systems, and customer databases could be manipulated by a carefully crafted web page to exfiltrate sensitive information. Traditional security models, built around human users who can spot obvious phishing attempts, break down when the “user” is an AI system that processes information differently.

The survey reveals a concerning gap in preparedness. While general security frameworks exist for AI agents, “studies on defenses specific to OS Agents remain limited.” This isn’t just an academic concern — it’s an immediate challenge for any organization considering deployment of these systems.

The reality check: Current AI agents still struggle with complex digital tasks

Despite the hype surrounding these systems, the survey’s analysis of performance benchmarks reveals significant limitations that temper expectations for immediate widespread adoption.

Success rates vary dramatically across different tasks and platforms. Some commercial systems achieve success rates above 50% on certain benchmarks — impressive for a nascent technology — but struggle with others. The researchers categorize evaluation tasks into three types: basic “GUI grounding” (understanding interface elements), “information retrieval” (finding and extracting data), and complex “agentic tasks” (multi-step autonomous operations).

The pattern is telling: current systems excel at simple, well-defined tasks but falter when faced with the kind of complex, context-dependent workflows that define much of modern knowledge work. They can reliably click a specific button or fill out a standard form, but struggle with tasks that require sustained reasoning or adaptation to unexpected interface changes.

This performance gap explains why early deployments focus on narrow, high-volume tasks rather than general-purpose automation. The technology isn’t yet ready to replace human judgment in complex scenarios, but it’s increasingly capable of handling routine digital busywork.

What happens when AI agents learn to customize themselves for every user

Perhaps the most intriguing — and potentially transformative — challenge identified in the survey involves what researchers call “personalization and self-evolution.” Unlike today’s stateless AI assistants that treat every interaction as independent, future OS agents will need to learn from user interactions and adapt to individual preferences over time.

“Developing personalized OS Agents has been a long-standing goal in AI research,” the authors write. “A personal assistant is expected to continuously adapt and provide enhanced experiences based on individual user preferences.”

This capability could fundamentally change how we interact with technology. Imagine an AI agent that learns your email writing style, understands your calendar preferences, knows which restaurants you prefer, and can make increasingly sophisticated decisions on your behalf. The potential productivity gains are enormous, but so are the privacy implications.

The technical challenges are substantial. The survey points to the need for better multimodal memory systems that can handle not just text but images and voice, presenting “significant challenges” for current technology. How do you build a system that remembers your preferences without creating a comprehensive surveillance record of your digital life?

For technology executives evaluating these systems, this personalization challenge represents both the greatest opportunity and the largest risk. The organizations that solve it first will gain significant competitive advantages, but the privacy and security implications could be severe if handled poorly.

The race to build AI assistants that can truly operate like human users is intensifying rapidly. While fundamental challenges around security, reliability, and personalization remain unsolved, the trajectory is clear. The researchers maintain an open-source repository tracking developments, acknowledging that “OS Agents are still in their early stages of development” with “rapid advancements that continue to introduce novel methodologies and applications.”

The question isn’t whether AI agents will transform how we interact with computers — it’s whether we’ll be ready for the consequences when they do. The window for getting the security and privacy frameworks right is narrowing as quickly as the technology is advancing.
