External assessment of new AI models is essential to ensure they are unable to cause large-scale harm such as supporting WMD development, or automating cyberattacks.

However, industry norms around these external AI model evaluations are varied and inadequate which make them ripe for exploitation.

They therefore require urgent coordination and collaboration to ensure the security of the most sophisticated AI models currently available.

Our latest paper by @LouMarieHSD, Elijah Glantz and @dcuthbert delivers a critical framework for securely enabling third-party evaluation of frontier AI models, directly addressing the urgent need for robust safety and security in the defence and security sector as AI capabilities rapidly advance. 

The image is a visual representation from the paper of direct and indirect pathways of access exploitation that may lead to weaponisation of the model to cause real-world harm.

New research by @LouMarieHSD and Prerana Joshi shows cyber attribution in the Global South isn’t binary, but a spectrum shaped by politics, economics and risk, challenging Western assumptions about ‘naming and shaming’ as a universal tool of cyber statecraft.

States balance signalling capability with risks: escalation, economic fallout and exposing vulnerabilities. Many prefer partial or no attribution, especially where conflict, trade ties or ‘saving face’ shape decision-making.

Private sector threat intelligence plays a major role. Some states rely on firms as a proxy for attribution, signalling awareness without official statements, raising questions about sovereignty and dependency.

The paper calls on policymakers to move beyond Western models, engaging Global South partners on their own terms, with better understanding of local decision-making, technical cultures and regional dynamics.
