Visa open-sourced part of its AI cyber defence and let agents spend

Visa open-sourced part of its AI-powered cyber defence after vulnerabilities exposed by Anthropic's Mythos model and an AI-agent escape from a Hugging Face testing sandbox. The company also confirmed it has started allowing certain AI agents to make payments on its rails, without disclosing how many or under what controls.

• Visa processes about 1 billion payments a day worth roughly $15 trillion a year
• Industry estimates say AI agents could handle a third of online commerce, near $3.1 trillion, by 2030
• The open-sourcing followed weaknesses exposed by Anthropic's Mythos and a Hugging Face sandbox escape
• Visa did not disclose how many agents can pay or what authorization controls apply
