Conduct dual-use bio research
Verified
Researchers in unsupported regions used proxy networks to route dual-use scientific queries through other systems, including research involving pathogens, immune evasion and other high-risk biological topics.
Run propaganda at scale
Verified
Over just two weeks in April 2026, Anthropic found more than 4,700 different Claude-powered AI characters chatting with at least 25,000 real users, sending about 2.36 million messages in total, which represents large-scale automated propaganda/fraud operations.
Fully automate hacking/phishing/malware iteration
Verified
Chinese-speaking operators used Claude for offensive cyber work, including vulnerability research, with one continuously running workflow generating more than a dozen possible zero-day findings in a single month, while parallel systems handled reconnaissance, malware development and intelligence collection. Additionally, research evaluated large language models' capability to conduct fully automated spear phishing campaigns, with researchers developing and testing an AI-powered tool to automate spear phishing using AI agents based on GPT-4o and Claude 3.5 Sonnet.
