$4.7 Trillion in Assets in London's Financial District Rely on Outdated Encryption

en.Wedoany.com Reported - Nearly $4.7 trillion in assets held in the City of London currently depend on encryption standards established half a century ago, exposing critical global infrastructure to increasingly severe cyber threats. With the rapid deployment of artificial intelligence, while businesses and nations remain unprepared for modern cyberattacks and the future decryption capabilities of quantum supercomputers, this vulnerability gap is widening. The disconnect between technological progress and protection has sparked calls for systemic cyber resilience, including embedding quantum-safe encryption directly into network hardware.

The rapid advancement of AI and the potential threat of quantum computing breaking existing encryption have highlighted the reliance on aging infrastructure. The exposure extends beyond the financial sector, impacting energy, telecommunications, retail, healthcare, and industrial operations—industries all interconnected through systems technically inadequate to counter contemporary risks. A major financial institution reported thousands of unresolved security vulnerabilities despite years of efforts to control the situation. "Harvest now, decrypt later" attacks are already underway, with attackers collecting data in anticipation of future quantum computers being able to decrypt it. Google has set a deadline for post-quantum migration to secure future systems.

Research from cybersecurity firm Sitehop indicates that while regulators have issued guidance requiring the creation of encryption inventories, migration of critical assets, and full asset migration, there is currently a lack of enforcement power to compel necessary changes. Board-level discussions have shifted from preventing attacks to minimizing recovery time, signaling that breaches are now considered inevitable. Protecting the network layer—the infrastructure through which data flows—is crucial, especially vulnerable VPN connections. As one executive at a leading financial institution put it: "We used to lock the front door at night; now Tom Cruise is coming down the chimney, and we're still arguing about which lock to buy." Hardware-based encryption offers a more sustainable, efficient, and cost-effective approach than software alone, and regulators have clearly mandated encryption inventories by one date, critical asset migration by another, and full asset migration by a final deadline.
