According to Reuters, following the $6.3 billion hack on Binance last week, the U.S. Federal Reserve and the Office of the Comptroller of the Currency (OCC) began contacting banks on Monday to inquire about any unusual activity or service disruptions in their systems, aiming to assess the risk of cryptocurrency market security incidents spreading to the traditional financial system. Sources indicate that several banks are conducting security diagnostics on their internal systems and evaluating potential vulnerabilities that could be exploited using similar attack methods. A cybersecurity team from a major U.S. bank has reached out to Binance and is preparing an internal report, which may lead to a review of systems and updates to cybersecurity measures. Binance stated that it is currently in close contact with global regulators to provide timely updates on the security incident. The Federal Reserve and OCC declined to comment. Sources also noted that the rapid evolution of AI models has increased the difficulty for banks in preventing hacking attacks, leading them to invest significant resources in reviewing and patching cybersecurity code.
