AI Coding Agents Exploited via Hallucinated Package Names

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.5 BleepingComputer

Researchers from Tel Aviv University, Technion, and Intuit have demonstrated that AI coding agents across tools like Cursor, Copilot, and Gemini CLI predictably hallucinate package, domain, and repository names that attackers can pre-register to deliver malicious code. The attack—variously branded slopsquatting, phantom squatting, and HalluSquatting—requires no phishing, no stolen credentials, and no direct user interaction, only an automated agent with permission to fetch external resources. Because agents handle delivery autonomously and hallucinations are reproducible at up to 100% consistency, the technique scales to botnet-level compromise without traditional malware infrastructure.

HalluSquatting Exploits AI Hallucinations for Botnet RCE

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.5 SecurityWeek

Researchers have demonstrated a novel attack technique called 'HalluSquatting', which weaponises AI hallucinations by registering fake package names that LLMs fabricate, turning them into malware delivery vectors. When developers trust AI-recommended dependencies and install the squatted packages, attackers can achieve remote code execution and potentially recruit victim machines into botnets. The technique represents a significant escalation in the practical exploitation of LLM hallucinations beyond misinformation into active infrastructure compromise.
