Your AI Tool is Already Leaking Information. Redesigning AI Governance Based on 8 Real-World Incidents
MONO BRAIN Inc. will hold a webinar on May 13, 2026, analyzing 8 real-world AI incidents involving information leakage and uncontrollable automated execution by AI tools. The webinar will explain design flaws and countermeasures, proposing a governance design that controls risks without halting AI utilization.

The widespread adoption of AI tools has dramatically improved corporate productivity.
However, behind the scenes, incidents not anticipated by traditional security, such as "information leakage occurring unnoticed" and "uncontrollable automated execution," are actually happening.
MONO BRAIN Inc. will host a webinar that analyzes 8 real-world AI incidents, explaining their underlying structures and "design flaws that could have been prevented."
■ Background: The incidents are not "special cases"
Incidents involving M365 Copilot and AI agents are not limited to specific companies or environments.
Cases analyzed in this report clearly show that "design and operational level problems" such as:
・Excessive privilege grants through OAuth / API integration
・Designs that over-rely on external input
・Insufficient control over automated execution by agents
have directly led to serious accidents.
In other words, the essence of the problem is not that AI is dangerous, but that it is being used defenselessly with "excessive privileges."
■ What will be explained in this webinar
・Why do AI incidents happen even though they could have been prevented?
・How does zero-click confidential information leakage occur?
・Why couldn't database deletion by AI agents be stopped?
・The structure where OAuth and API integration become "full authorization"
・The impact of prompt injection on practical operations
・Basic patterns for governance design based on AI utilization
■ Practical Edition: Governance Design to Not Stop AI Utilization
This webinar will not merely prevent risks, but will explain approaches to control risks while maintaining on-site productivity.
・Proactive control of information leakage through pre-transmission masking
・Guiding "shadow AI" from "prohibition" to "safe options"
・Browser-based introduction design that does not change on-site workflows
We will introduce methods to resolve the dilemma of "security strengthening leading to non-use" and achieve realistic governance based on AI utilization.
