World leaders must wise up to threat of cyber-attacks or rogue fridges will be least of their worries | Heather Stewart

Rogue French fridges were an unlikely talking point for the world’s leading economists, central bankers and finance chiefs meeting in a sultry Bangkok last week – helping to underline the spiralling cost of cyber-attacks. Kristalina Georgieva, the managing director of the International Monetary Fund, seized on news that supermarket chains across France had to chuck out piles of spoiled food after hackers accessed their fridge controls and turned up the temperature to 50C. Speaking at the fund’s annual meetings i…

World leaders must wise up to threat of cyber-attacks or rogue fridges will be least of their worries | Heather Stewart

In brief

At the IMF annual meetings in Bangkok in October 2026, Kristalina Georgieva used a hack of French supermarket fridge controls to illustrate the rising cost of cyber-attacks. She said AI is intensifying digital fraud and could erode trust in the financial system. JP Morgan's Jamie Dimon said the bank would not let digital agents act for customers.

The concern matters because trust in money underpins economic activity, and financial rules are being outpaced by AI tools that can move deposits instantly or act on a user's behalf. How much harm will occur is uncertain. Regulators' responses so far, such as incident reporting and G7 resilience simulations, are early steps, and the article says the prospects for international cooperation look bleak.

Main points

  1. Hackers reportedly set French supermarket fridge controls to 50C, forcing stores to discard spoiled food.
  2. Georgieva fears AI-driven cybercrime could push people to hoard cash, as in her Bulgarian childhood.
  3. Dimon said JP Morgan would not allow AI agents to operate on customers' behalf, warning there could be thousands of rogue agents.
  4. Regulators worry that AI agents moving deposits could cause herding and speed up bank runs.
  5. G7 finance ministers said they will simulate the financial system's resilience to cyber-attacks.

The problem

AI is amplifying digital fraud and enabling autonomous financial agents, which senior policymakers fear could erode public trust in banks, accelerate bank runs and leave liability unclear when agents act badly.

The rundown

The article opens with the French fridge hack as a tangible example of cyber-attack costs. It then moves to Georgieva's warning that AI-generated scams, including celebrity deepfake adverts for cryptocurrencies or gold and more prolific email scams, could shake consumer confidence in mainstream banks.

It describes AI agents, including Meta's Muse, that can take users' financial details and move money to the highest savings rates. Regulators fear herding effects and unclear liability, and the author compares the legal ambiguity to the 2008 crisis, when complex liability structures made products impossible to value.

Andrew Bailey, who chairs the Financial Stability Board, cited an Anthropic warning that AI models might soon self-replicate in domestic devices. On policy, the article notes a US taskforce setting up reporting of breaches and jailbreaks but not pre-launch testing, a UK pledge to raise AI safety in its G20 presidency, and the planned G7 simulations.
