AI coding assistants like GitHub Copilot, Aider, and Tabby are no longer optional productivity tools—they’ve become core components of modern development pipelines. But with this shift comes new risk. These assistants don’t just suggest syntax—they can access internal repositories, surface sensitive code, commit changes, and even expose infrastructure to the internet, all with a single prompt.
Consider this: what happens when an assistant uploads your code to a public server for processing? Or hallucinates a secure configuration that accidentally exposes a production database? Or suggests insecure code that a junior developer unknowingly commits to main? These risks aren’t theoretical—they’re already here.
Assistant Integrations: Power and Exposure
Let’s look at how today’s tools operate:
GitHub Copilot is deeply embedded in IDEs like VS Code and JetBrains, pulling context from repositories, summarizing pull requests, and committing code. It integrates with Codespaces and git tools to infer tasks from natural language prompts. Aider supports LLMs like GPT-4o and Claude, mapping codebases, committing automatically, and even responding to voice and image input. Tabby, the self-hosted alternative, integrates with GitHub and GitLab and allows full customization of completions, commit generation, and OpenAPI-based integration into cloud IDEs.
Enterprise-focused tools like CodeGPT, GitLoop, Amazon Q Developer, and Gemini Code Assist go even further, combining code assistance with CI/CD awareness, test coverage, documentation generation, and even CLI completion. But with each integration, these assistants gain deeper access—and introduce new blind spots that traditional compliance frameworks simply don’t cover.
Threat Model for AI Coding Assistants
Attack Surface: IDEs, Repositories, CI/CD, Cloud Services
Risks: Prompt Injection, Secret Exposure, Vulnerable Code Suggestions, External Uploads, Infrastructure Misconfiguration

How We Attack: Real World, Not Simulated
ZioSec conducts adversarial testing against assistants in sandbox and production mirrors. We start with a framework like the MITRE ATLAS, then create realistic scenarios that test for:
Vulnerable code, infastructure exposure, prompt injections, contextual abuse in the code base, and so on.
We’ve exploited all of these—often with tools like Copilot, Aider, and Tabby. Their functionality is powerful—but unchecked, it becomes dangerous. And unlike traditional pentests, our approach validates whether safeguards like repo access controls, audit trails, or human-in-the-loop reviews can actually prevent a catastrophic mistake.
Compliance vs. Offensive Testing

The Outcome: Exposure Reduced. Trust Earned.
Our testing uncovers vulnerabilities invisible to traditional audits. Tools like Copilot and GitLoop had been generating code snippets that bypassed secure coding guidelines, while others introduce risks through insecure default settings in self-hosted deployments. We work closely with the clients to harden IDE plugins, retrain developers, and create automated monitors for assistant-generated commits.
What started as a fear of AI complexity became a foundation of trust. Clients can now prove—internally and externally—that their AI tooling is secure, explainable, and aligned to frameworks like NIST AI RMF and ISO/IEC 42001.
