Amazon’s AI Coding Tool, known as Amazon Q, recently faced a serious security breach that exposed nearly 1 million developers to the risk of a full system wipe. The issue stemmed from a prompt injection vulnerability in the VS Code plugin, allowing hackers to silently insert data-wiping commands. This incident highlights growing concerns around the trust and safety of AI developer tools. As more teams adopt AI to boost productivity, it’s critical to understand how these tools can also introduce new cybersecurity threats if not properly secured.
What Is Amazon Q AI Coding Assistant?
Amazon’s AI Coding Tool is a tool designed to help developers write code faster using artificial intelligence. Integrated with the popular Visual Studio Code (VS Code) editor, it can suggest code, answer questions, and automate tasks. It connects with AWS services, making it easier for teams to build and deploy applications. While it boosts productivity, it also has deep access to your developer environment, which means any vulnerability, like the recent prompt injection attack, could put your entire system at risk. Understanding how Amazon Q works is key to seeing why this security flaw was so dangerous.
The Vulnerability: How the Breach Happened
The breach happened through a prompt injection attack, where a hacker submitted a malicious pull request to Amazon’s Q AI tool. This pull request included hidden data-wiping commands that the AI assistant later interpreted and executed. Because the assistant had access to terminal commands via the Amazon Q VS Code plugin, the injected instructions had the power to delete developer files or wipe entire systems. What made this worse is that it looked like a normal request, so it bypassed detection. This kind of AI exploit shows just how fragile automated coding tools can be when not properly secured.
Why the Flaw Went Undetected for Days

One of the most alarming parts of this incident is how long it went unnoticed. For nearly five days, the malicious prompt injection remained active in the system without raising any red flags. Because Amazon Q AI generates code automatically and interacts silently with tools like AWS CLI and VS Code, many developers didn’t realize anything was wrong. This highlights a bigger problem: AI coding tools can act without obvious warning signs. Without proper monitoring or validation, dangerous actions like system wipes can slip through unnoticed, putting thousands of developer environments at serious risk.
Who Was Affected & What Could Have Happened
Nearly 1 million developers who installed the Amazon Q coding assistant through Visual Studio Code were potentially exposed. Anyone using version 1.84 of the extension could have unknowingly triggered a destructive command, leading to loss of files, corrupted systems, or even full dev environment wipeouts. While there’s no confirmed report of actual damage, the risk level was dangerously high. This incident proves that even trusted tools like Amazon’s AI-powered extensions can open the door to serious threats if vulnerabilities like prompt injection aren’t caught early.

Amazon’s Response: Fixes, Statements & Controversies
After the vulnerability was discovered, Amazon quickly patched the issue in the affected Q AI extension. However, many in the developer community raised concerns about Amazon’s delayed disclosure and the lack of clear communication. For several days, users were unaware that their VS Code environments were at risk. While Amazon eventually acknowledged the problem, some experts believe the response lacked transparency. This situation has sparked debates about how tech giants handle AI-related security incidents and whether users should be notified sooner when AI coding tools are compromised.
AI & Security: A Growing Supply Chain Threat
This incident is a warning sign about the hidden risks of AI in the software supply chain. As more developers rely on AI-powered tools like Amazon’s AI Coding Tool, the potential for unseen vulnerabilities increases. A single compromised plugin or prompt can impact thousands. The problem isn’t just the AI, it’s how deeply these tools integrate into coding environments. Developers must now consider AI security as seriously as they do traditional software dependencies.
How to Protect Your Developer Environment from AI Vulnerabilities
To stay safe while using tools like Amazon Q AI, developers should take a few simple but important steps. First, regularly audit your plugins and extensions, especially those with terminal access like VS Code tools. Always check for security updates or patches. Use prompt filtering to prevent unexpected commands. Consider sandboxing your development environment to limit damage if something goes wrong. Most importantly, stay informed. AI coding assistants are powerful, but they still need oversight and caution to remain secure.
What This Incident Teaches Us About Trust in AI
Amazon’s AI Coding Tool shows that trust in AI tools shouldn’t be automatic. While these assistants can speed up coding, they also introduce new security risks, especially when they can run powerful commands. Developers must treat AI suggestions with caution, review outputs carefully, and demand better transparency from providers. As AI becomes more integrated into daily workflows, it’s essential to balance convenience with responsibility and control.
