UK Banks Face Growing Threat of Cyber-Attacks

Strategic Insights -

A cyber-attack on a major UK bank could unleash widespread chaos, with millions of direct debits failing, online banking blocked, and cash machines denied. This situation is not far-fetched, as it is considered a "reasonable worst-case scenario" by the government. The financial industry is a prime target, with billions of pounds being spent on cybersecurity measures. Banks are expected to allocate 11% of their IT budgets to cybersecurity by 2025, with forecasted IT budgets of $290bn (£214bn) this year.
