Slopsquatting, Phantom Domains, and HalluSquatting Are the Same AI Attack

AI coding agents sometimes generate fake names for software libraries, domains, or repositories that sound real but don't actually exist, a flaw called hallucination (when an AI generates plausible-sounding but incorrect information). Attackers can predict these fake names in advance, register them, and trap developers into using malicious code when their AI agents automatically fetch these nonexistent resources. This attack, known by three names—slopsquatting, phantom squatting, and hallusquatting—exploits the same core problem: systems trust outputs from AI models without verifying they actually exist.
