  "account": "AI leaders Anthropic and OpenAI, along with 120 companies from technology, finance, telecommunications, and related sectors, have signed an open letter urging greater collective action to address cyber threats arising from AI advancements. The letter, published on 27 August, warns that AI-enabled cyberattacks are set to become more widespread and sophisticated, posing a risk to vital infrastructure like hospitals, water treatment plants, and internet access. To combat this, the signatories propose leveraging AI technology to strengthen existing cyberdefences and make digital environments more secure. The letter outlines three key principles for a collective response: acknowledging the inadequacy of current security measures, empowering defenders with cyber-capable AI, and mobilising a collective response. It calls for organisations, particularly those managing critical infrastructure, to receive a surge in tools and resources, and for sharing of tools, knowledge, and verified fixes to bolster overall security. Additionally, the letter urges governments to coordinate cyber defence efforts locally, nationally, and internationally, while imposing costs on attackers, particularly through frontier AI companies like Anthropic and OpenAI. These companies are encouraged to provide responsible model access, build observability and security tools, ensure accountable and traceable AI identities, and share best practices in continuous monitoring.",
