AI code generators hallucinate non-existent packages, study finds · 4 sources tracked

By PulseAugur Editorial · [4 sources] ·

A recent study published at the USENIX Security Symposium revealed that AI code-generating models hallucinate non-existent package names at a significant rate, with 19.7% of recommended packages being fabricated. This issue is particularly prevalent in open-source models, which showed a 21.7% hallucination rate compared to 5.2% for commercial models. The research also highlighted that a substantial portion of these hallucinations are deterministic, meaning attackers can register these invented package names and exploit the vulnerability before security measures catch up. AI

IMPACT AI-generated code could introduce significant security risks by recommending non-existent or malicious packages.
