OpenAI, Tech Giants Warn of AI Cyber Threats

OpenAI has published an open letter on global cyber defense, co-signed by more than 100 companies including Microsoft, Google, AWS, Anthropic, Cisco, CrowdStrike, Deutsche Telekom, SAP, and Mastercard, according to a report by The Decoder. The letter warns that artificial intelligence enabled cyberattacks will become far more widespread and sophisticated, placing hospitals, water utilities, and other vital infrastructure at the highest risk.

According to the text, the signatories argue that current artificial intelligence advances are already giving defenders new ways to fix long-standing weaknesses. They urge organizations to deploy these security tools while defenders still maintain an edge. The coalition calls on corporate leadership to make cybersecurity a top priority, asks governments to increase funding and coordination, and requests that artificial intelligence companies provide affordable security tools for underfunded organizations. The letter also highlights the urgent need to address long-standing vulnerabilities such as unpatched software and weak authentication.

The Decoder notes that these concerns are reinforced by a joint warning issued in mid-August by the National Security Agency, the Cybersecurity and Infrastructure Security Agency, and the Federal Bureau of Investigation. That warning revealed that attackers are already utilizing artificial intelligence to write exploit scripts targeting industrial control systems across energy, water, chemicals, and manufacturing sectors.
