AI leaders Anthropic and OpenAI are notable signatories to the letter.
Around 120 companies and entities from the world of tech, finance, telecoms and related industries have signed an open letter calling for greater collective action on cyber defence by society and business in the face of growing AI-enabled security threats.
AI leaders Anthropic and OpenAI are notable signatories to the letter – alongside companies such as Google, AWS, Visa, ServiceNow, PwC, Oracle, Microsoft, MasterCard, IBM, Hugging Face, Deutsche Telekom, Cloudflare and Accenture – warning of “a limited window to strengthen cyber defences”.
“In the coming months, AI-enabled cyberattacks will become far more widespread and sophisticated as models around the world become increasingly capable,” the letter – published yesterday (27 August) – said, warning that vital infrastructure underpinning hospitals, water treatment plants and internet access could be at risk.
The counter-measure to this, according to the letter, is to use advancing AI tech “to fix weaknesses that have accumulated for years” in order to “make our digital world much more secure”.
