Slopsquatting/Package Hallucination Research

System Description

LLM code generation across major models (GPT-4, Claude, Gemini, Llama, etc.)

Authoritative Output Type

Code recommendations including package/library import statements

Missing Required State

Package existence verification, supply chain security validation, hallucinated dependency detection

Why This Is SAF

Research testing 16 LLMs generating 576K code samples found ~20% of recommended packages didn't exist; 43% of hallucinated package names repeated consistently across prompts, making them exploitable attack vectors

Completeness Gate Question

Do all recommended packages exist in official registries and have verified provenance?

Documented Consequence

Security vulnerability class established; researchers registered 'slopsquatted' packages that were downloaded thousands of times; fake 'huggingface-cli' downloaded 30K+ times

Notes

- **Verified**: 2025-12-19 - **Research Date**: 2024 - **Notes**: Multiple independent research teams confirmed hallucinated package vulnerability; term 'slopsquatting' coined for this attack class

Prevent this in your system.

The completeness gate question above is exactly what Ontic checks before any claim gets out. No evidence, no emission.
