   Anthropic Says Claude AI Used for Weapons, Spying and Cyber Attacks

   Artificial intelligence company Anthropic reports that global threat actors used its Claude AI model for malicious activities including weapons development, cyber operations, spying, political influence, and scams. Users in Houthi-held Yemen attempted to build advanced weapons and missiles using the software instead of traditional software engineers. Additionally, Iran utilized the American AI model to target United States Navy warships. Anthropic states that it blocked these efforts and banned the associated accounts after detecting the misuse.

   Why it matters

Threat actors are increasingly attempting to leverage generative systems for strategic operations, forcing tech companies to expand monitoring and enforcement. These incidents intensify the ongoing debate surrounding AI safety and the potential risks of dual-use technologies.
