Advanced language models increase the risk of cyberattacks

New advanced AI models, often referred to as Frontier AI Models (FAIMs), have a significant capacity to identify and exploit weaknesses in operating systems and software, which are central to the current ICT infrastructure and financial systems. 

In a press release, the ESRB states:

• Frontier AI models are changing the cyber threat landscape for the EU financial system.
• The models may increase speed, scale and sophistication of cyberattacks.
• Relevant authorities should reflect these risks in supervisory and oversight work.

The ESRB highlights that the frontier AI models are likely to strengthen cyber resilience in the long term. In the short term, however, they may provide an advantage to threat actors, enabling them to discover vulnerabilities with increased speed.

The threat landscape also affects the Norwegian financial system

Norges Bank and Finanstilsynet support the warning from the ESRB. New technology and artificial intelligence-based solutions can be used in institutions' defence against cyber threats but also in malicious attacks.

Rapid technological developments place high demands on institutions' digital defences, requiring them to maintain up-to-date systems and sufficient capacity to develop and implement a large number of patches and security updates. Norwegian financial institutions must closely monitor developments in the cyber threat landscape and ensure effective governance and control of both their own solutions and ICT operations that are fully or partly outsourced to third parties.

Norges Bank and Finanstilsynet follow up institutions' preparedness against malicious cyberattacks in their ongoing oversight and supervisory work within their respective areas of responsibility.
