Google, Microsoft and OpenAI among 100 firms calling for better cyber defences

A group of 100 firms, including Google, Microsoft, Anthropic and OpenAI, have signed an open letter calling on countries and organisations around the world to beef up their cyber defences before AI grows powerful enough to override them. The letter warns, external cyber-attacks which use AI will become both more widespread and more sophisticated in a matter of months as the technology rapidly improves. The group says current status quo security measures won't be enough and criticises the historic under-resourcing of security around critical infrastructure. We have a limited window to improve cyber defences, the letter begins. Other firms to have signed the letter include banks such as Capital One, payment processors MasterCard and Visa, and other major tech firms including Adobe, Oracle and IBM.
