Hackers breached OpenAI, Anthropic, and other AI labs

• Security breaches targeted multiple major AI companies including OpenAI, Anthropic, AISI, and Hugging Face.
• The incidents exposed gaps in safety measures like alignment training, which teaches models to refuse harmful requests, and security classifiers that filter dangerous outputs.
• Damage remained limited because current AI models have restricted capabilities, but protections may weaken as models become more powerful.
