G7 Plans Simulated AI Cyber Attacks on Banks to Test Defences
The G7 countries will run exercises simulating AI-powered cyber attacks on banks, aiming to strengthen financial sector defences as concerns about new threats grow.

The short version
The G7 group of major economies plans to run practice drills that simulate cyber attacks on banks using artificial intelligence. These exercises are meant to help banks and governments get ready for new types of threats that use AI. The plan has only been reported by one news outlet so far, and no official details have been released.
What happened?
The Financial Times reports that G7 countries have agreed to run tabletop exercises simulating AI-powered cyber attacks on banks. The goal is to prepare for future threats as AI becomes more common in cyber crime. No official statements have been made yet.
What is being planned?
According to the Financial Times, the G7 group of major economies has agreed to run tabletop exercises simulating artificial intelligence (AI) powered cyber attacks on banks. These drills are intended to help countries prepare for possible future threats as AI becomes more widely used in both legitimate and criminal activity. The report says finance ministers have agreed on this plan, but there are no details yet from official government sources or the banks themselves. [Financial Times (opens in a new tab)]
Why are AI attacks a concern for banks?
Banks have long been targets for cyber criminals because of the money and sensitive data they hold. The rise of AI tools has made it easier for attackers to automate tasks, create convincing phishing emails, and find weaknesses in systems. Financial institutions are worried that AI could be used to launch more sophisticated attacks, including those that adapt in real time or bypass traditional security controls.
What are tabletop exercises?
A tabletop exercise is a discussion-based session where key staff walk through a simulated incident scenario. The aim is to test how well an organisation would respond to a crisis, identify gaps in plans, and improve coordination between different teams. In this case, the G7 countries will use the exercises to see how banks and governments would handle a cyber attack that uses AI techniques.
What could these exercises look like?
While the details are not public, exercises could include scenarios such as AI-generated phishing campaigns, attacks that use large language models to mimic staff or customers, or attempts to manipulate financial data. The focus would be on how quickly banks can detect and respond to these new types of threats, and whether current defences are enough.
What happens next?
The Financial Times is the only outlet to report this plan so far, and there is no official statement from the G7 or affected banks. If confirmed, these exercises could lead to new guidance for the financial sector and help shape how banks invest in AI defences. For now, the story highlights growing concern about AI risks in critical infrastructure, and the need for ongoing training and preparation.
What should banks and security teams do?
Security professionals in banking should stay informed about AI-driven threats and ensure their incident response plans are up to date. Regular exercises, whether tabletop or technical, help teams prepare for emerging risks. Monitoring for unusual activity, training staff to spot AI-generated phishing, and reviewing access controls are all important steps.
Claimed vs confirmed
- Unconfirmed
G7 countries have agreed to run simulated AI cyber attacks on banks.
Reported by the Financial Times; no official confirmation from governments or banks.
The impact
- Money
- If a real AI-powered attack succeeded, banks could face financial losses and possible regulatory fines. Under UK GDPR, fines can reach up to £17.5m or 4% of global turnover.
- Reputation
- Running these exercises shows banks and governments are taking AI threats seriously, which may reassure customers and investors. However, any real incident could still damage trust.
- Customers
- Customers' money and personal data are at stake if banks are not prepared for new AI-driven threats. These exercises aim to improve protection for ordinary people.
Why it matters
Banks are critical to the economy and are frequent targets for cyber attacks. As AI tools become more advanced, attackers could use them to launch more effective and harder-to-detect attacks. Preparing for these threats helps protect people's money and the stability of the financial system.
How does it work?
Tabletop exercises are discussion-based simulations where teams walk through a hypothetical incident. In this case, the scenario would involve AI-powered cyber attacks, such as automated phishing or AI-generated social engineering, to test how banks and governments would respond.
Key points
- G7 countries plan to run simulated AI cyber attacks on banks.
- The goal is to improve readiness for new types of threats.
- Tabletop exercises help test and improve incident response plans.
- AI can make cyber attacks more convincing and harder to detect.
- The plan is reported by one outlet and not yet confirmed by officials.
