LLM package security: Timing of registration beats existence checks

A security researcher discovered that relying solely on package existence checks for LLM-generated names is insufficient, leading to false positives. By analyzing the timing of package registration against the first time an LLM hallucinated a name, the researcher developed a more accurate method. This new approach correctly identifies packages registered *before* an LLM suggested the name as trustworthy, distinguishing them from those potentially registered *in response* to a hallucination.
