Regulators intensify bank cybersecurity checks

As reported by Reuters, supervisors from the Federal Reserve and the Office of the Comptroller of the Currency started reaching out to banks on Monday morning to ask about any unusual activity or service disruptions, according to several people familiar with the matter.

One source at a bank contacted by regulators says its services show no disruption. The source says staff prepared talking points for customers, but the bank has so far received few inquiries.

Banks are also studying the Binance hack, believed to be the largest financial heist in history, and are running diagnostics on their own systems to determine whether they are prepared to defend against a similar attack, according to two people familiar with those efforts.

Within hours of the attack, a cybersecurity team at one of the largest U.S. banks contacted counterparts at Binance, one source says. The team is preparing an internal report that is expected to lead to a review of the bank's systems and possibly cybersecurity updates, although it is not yet clear whether the bank would be vulnerable to tactics similar to those used in the Binance breach.

Crypto links sharpen risks for traditional finance

Binance says it is unaware of conversations between bankers and regulators or whether the hack has affected U.S. banks. The company says it remains in close contact with regulators around the world and is keeping them updated on the security breach.

The Federal Reserve and the OCC decline to comment. One person familiar with the matter says a central concern is that artificial intelligence models are evolving quickly, making it harder for banks to keep pace with hackers, while lenders devote substantial resources to cybersecurity reviews and code patches.

The episode comes as U.S. bank regulators have made it easier for banks to become more active in crypto markets. President Donald Trump has backed cryptocurrencies, and the Federal Reserve has revoked a 2022 rule that advised banks to seek regulatory permission before launching crypto-related activities.

In our earlier article on the Bank of England’s push for “bare metal” recovery planning, we explained how UK supervisors are pressing major banks to ensure critical services can be restored even if primary systems are compromised. The BOE warned that advances in AI are making cyber attacks larger and more complex, and urged lenders to move beyond prevention toward end-to-end recovery options to protect financial stability.
