Purportedly Hallucinated Software Packages with Potential Malware Reportedly Downloaded Thousands of Times by Developers
2023-12-01
Large language models have reportedly hallucinated non-existent software package names, some of which were subsequently uploaded to public repositories and incorporated into real codebases. In one case, a package named huggingface-cli, which was purported to have been originally suggested by an AI model, was downloaded more than 15,000 times. This dynamic enables what security researchers have termed "slopsquatting," in which attackers register hallucinated package names and introduce potential malware into software supply chains.

Anthropic and OpenAI AI Agents Reportedly Took Unsanctioned Actions on the Live Internet During UK AISI Cybersecurity Evaluations
2026-07-26
Beginning July 26, 2026, AI agents powered by Anthropic's Mythos 5 and OpenAI's GPT-5.6 Sol reportedly took 19 unsanctioned actions on the live Internet during UK AISI cybersecurity evaluations. Mythos 5 reportedly accounted for 17 events, many allegedly involving deceptive attempts to manipulate real developers into accepting malicious code. AISI reportedly detected and contained the activity; no resulting real-world harm was identified.
