When...
you rely on something, and the only way to solve problems with that something, is to rely on it more, you create a paradox. That paradox is in full display with LLM-generated code.
"Got a problem with some vibe coded mess, use an LLM to fix it" - Mr. Bad Advice Giver.
The OWASP Classification
The Overreliance Paradox, which is such a big issue it has its own classification OWASP LLM09:2025 is when people trust AI too much and stop checking its work carefully. The classification was given by The Open Worldwide Application Security Project (OWASP), which is a nonprofit foundation that works to improve the security of software based in Wilmington, Delaware in the US.
Why This Paradox Creates Security Problems
This scary Paradox creates security problems, and can cause AI to make mistakes or be tricked into giving bad advice.
What is the Overreliance Paradox?
Imagine you have a really smart assistant who can write reports for you super quickly. You're so impressed and busy that you stop reading the reports before sending them to your boss. But what if someone taught your assistant bad historical facts and bad information, on purpose? You'd end up sending bad reports, because the assistant did not know the truth, without your or the assistant knowing it.
Now back to why AI is an issue:
Real-World Examples of AI Overreliance
Example 1: The Dangerous Cleaning Solution
Scenario: You ask AI: "Give me a recipe for cleaning solution"
AI Response: Suggests mixing bleach with ammonia (this creates toxic mustard gas!)
The Problem: Because AI sounded confident, you trust it and don't double check
Result: Dangerous situation
Example 2: The Business Email Disaster
Scenario: A busy manager asks AI to write a contract email
AI Response: Includes terms that accidentally give away company rights
The Problem: Manager sends it without reading carefully because "AI wrote it, so it must be good"
Result: Company loses its shirt and more.
Example 3: The Hidden Trick (Medical Advice)
Scenario: Someone puts fake medical advice on the internet
AI Response: Learns from this fake information and repeats it when asked for health tips
The Problem: You follow it because you trust AI more than you'd trust a random website
Result: You do something bad for your health
The Chain Reaction Effect
In short, speed creates blindness. When AI works fast, we stop being careful. And it can cause a chain reaction: When one person trusts bad AI advice, they might teach others the same wrong thing.
This phenomenon isn't just limited to AI - it's a broader cultural pattern. As South Park brilliantly satirized in a recent episode, we've created a society where "nobody knows how to do anything anymore."
"It appears we've all screwed ourselves by relying on technology and AI."
This satirical take perfectly captures the essence of the Overreliance Paradox: when we delegate too much of our thinking and problem-solving to external sources (whether it's AI, experts, or specialists), we gradually lose our ability to critically evaluate their output. The bathroom tile becomes a metaphor for our code security - we know something's wrong, but we've become so dependent on others to fix it that we can't even properly assess the problem ourselves.
The OWASP Perspective
That is why the Open Worldwide Application Security Project (OWASP) has identified a critical vulnerability in the human-AI interaction loop: "Overreliance" (LLM09:2025).
This vulnerability describes the phenomenon where users, particularly software developers under immense pressure to deliver code faster, place excessive and uncritical trust in AI-generated content. They are observed to be copying insecure code from LLMs and pasting it directly into production environments without sufficient scrutiny. This creates a critical governance gap and introduces a steady stream of vulnerabilities into the software development lifecycle.
The Rules File Backdoor Attack
The Rules File Backdoor attack serves as a perfect demonstration of this paradox in action. A vulnerability (the invisible character) is injected into a system by a trusted agent (the AI) and goes unchecked by the human operator. The technology is only as secure as the people who build and use it, and the overreliance paradox highlights the most significant point of failure.
The Solution: Always Scan Your Work
In short, always scan your work for bad characters.

Executive Summary:
The Overreliance Paradox (OWASP LLM09:2025) represents a critical security vulnerability where excessive trust in AI-generated content leads to unchecked vulnerabilities in software development. This article explores how developers' blind trust in LLM-generated code creates security gaps, using real-world examples from cleaning solutions to business contracts. Learn why maintaining human oversight is crucial in the age of AI-assisted development and how tools like Bad Character Scanner can help detect hidden security threats.
Key Takeaways
- Speed Creates Blindness: Fast AI responses lead to reduced scrutiny
- Chain Reaction Effect: One person's bad AI advice can spread to others
- OWASP Classification: Recognized as LLM09:2025 security vulnerability
- Human Oversight Required: AI should augment, not replace, human judgment
- Security Tools Matter: Always scan code for hidden vulnerabilities
