What if your AI assistant suddenly starts acting strangely? How to keep 'Agentic AI' safe

Imagine this: On a busy morning, you casually say to your ‘AI assistant,’ “Organize today’s meeting materials and email them to the team,” and head to work. The AI assistant finds the necessary files on its own, summarizes them, checks the team members’ email addresses, and hits send. If AI of the past was simply a ‘dictionary that answers questions,’ we are now entering the era of ‘agents’ (acting as proxies that judge and act for themselves) that directly use tools to complete goals.

However, this convenience brings new concerns. What if your AI assistant is tricked by a malicious attacker and leaks secret information instead of meeting materials? Or what if it makes unauthorized payments on its own? We have reached a point where we must consider ‘security’ as much as we consider the ‘performance’ of the technology.

Why is this important?

Autonomous agentic AI is deeply connected to the apps, web services, and even critical corporate systems we use. While previous AI was limited to simple information provision, agentic AI interacts directly with external tools, so the ripple effect of a security incident is much greater. According to the OWASP Top 10 for Agentic Applications 2026, these systems can be attacked in ways we cannot predict.

Simply put, if previous AI was a ‘talking dictionary,’ current agentic AI is a ‘driver behind the wheel.’ If a dictionary is hacked, it just gives wrong information, but if a driver is hacked, they can steer the car into the wrong place or cause an accident.

For developers and companies, these threats are not just problems caused by ‘bad luck.’ An AI agent without safety measures can halt business operations or put valuable customer data at risk. That is why security experts around the world have gathered to create ‘safety guidelines’ we must follow.

Easy to Understand: AI’s Seatbelt, OWASP Guidelines

Metaphorically, the recently announced OWASP Agentic Security Initiative (ASI) Top 10 is like a “traffic law book that AI agents must obey when driving.”

Even an AI with powerful intelligence based on Transformers (an AI architecture that understands the relationship between words in a sentence) can fall into traps or go down the wrong path while finding its way and driving on its own. This framework, created through peer review by over 100 experts, presents countermeasures for each threat situation from ASI01 to ASI10.

For example, when developing a ‘Model Context Protocol (MCP, a passageway connecting an AI assistant to external tools)’ that connects AI to external systems, it provides practical countermeasures on how to prevent external attackers from sneaking in through this passageway. Think of it as a detailed security blueprint that tells you not just to put a door on your house, but which locks to use and which CCTV to install to make it safe.

Current Situation: How far have we come?

The OWASP Top 10 for Agentic Applications, officially released in December 2025, is currently establishing itself as a strong benchmark in the field. Leading organizations and companies such as NIST (National Institute of Standards and Technology), Microsoft, and NVIDIA agree on the need for this guide and are participating. Source 14

There are already increasing cases of security teams and development teams collaborating using this guide. It is not just a theoretical list, but also provides extended code samples and hackathons that developers can immediately apply in the field, clearly guiding not only ‘what to be careful of’ but also ‘how to implement it.’ Source 6

What happens next?

In the future, AI agents will permeate deeper into our lives. It won’t be long before we say to our AI agent, “Go ahead and buy me a cost-effective vacuum cleaner,” instead of hitting the checkout button on a shopping app tonight. Source 10 When such an era arrives, our financial information or personal schedules will be entrusted to the hands of AI agents.

Therefore, developers will come to accept these OWASP guidelines not as an ‘option’ but as an ‘essential design directive.’ This is because security guides are evolving beyond just listing risks into strategies that defend with actual code and tools. The security of the AI services you use will also gradually be managed more tightly based on this framework. This is not just a technological advancement, but a basic etiquette and responsibility that we must acquire to coexist with AI.

MindTickleBytes’ AI Reporter’s Perspective

The speed at which AI agents are becoming smarter is amazing, but our responsibilities have grown just as much. Security is like a ‘rite of passage’ that AI must overcome to fully permeate into our society. The reason developers are paying attention to these safety guidelines now is that, in the end, only by being safe can we go further. If technology provides the gift of convenience, security is the essential wrapping paper that allows us to use that gift with peace of mind for a long time.
