Following a $6.3 billion theft case, U.S. regulatory authorities have launched an investigation into the potential impact of the Binance hack on American banks. As concerns grow that the security vulnerabilities may extend beyond this cryptocurrency exchange itself, attention to the issue has further intensified. On Monday morning, officials from the Federal Reserve and the Office of the Comptroller of the Currency contacted banks to inquire about any unusual activities or service interruptions.

Key Points

• The Federal Reserve and OCC are examining the exposure of banks to similar attacks.
• Binance stated that this operation lasted for five months and involved recruitment fraud, malware, and internal AI tools.
• Binance stated that it has intercepted or frozen approximately $2.85 billion and made up for 98% of the affected tokens.

Regulators examine the impact of the Binance hack incident on U.S. banks

The Federal Reserve and OCC regard this, the largest crypto theft in history, as a potential risk to traditional finance. Their focus of collaboration is on examining the banking system, as the connections between lending institutions and the crypto industry are deepening day by day.

Banks are studying this attack, running diagnostic programs, and reviewing their own network security defenses to prepare for similar tactics. Hours after the theft occurred, the cybersecurity team of a major American bank contacted the corresponding team at Binance.

The team is currently drafting an internal report that will lead to a thorough review of the banking system and may result in stronger security measures. Banks are also investing resources to check and fix their network security code.

Binance stated that the company maintains close contact with global regulatory authorities and continues to inform them about this security vulnerability.

A five-month-long attack turned internal tools towards engineers

Binance stated that this theft case stemmed from a five-month-long operation, during which the attackers began their activities long before they actually transferred any tokens. It all started with a fake job interview. The operation involved a disguised recruitment process, poisoned software download packages, and malware designed to evade terminal detection.

Bank authorities are reviewing the defensive measures in place to counter the tactics used in this attack.

Funds began to flow out of Binance's hot wallets on October 29th and were transferred across multiple blockchains. Blockchain analysis companies Chainalysis and TRM Labs linked this attack to TraderTraitor, which is considered to be related to North Korea.

Asset recovery and the broader role of banks in the field of cryptography

Binance stated that the company has frozen or intercepted approximately $2.85 billion in stolen assets and used its own funds to replenish 98% of the affected tokens. The exchange began to restore withdrawals in phases four days after the funds started to flow out, starting with Bitcoin.

This regulatory inspection occurred after a policy change in the United States that made it easier for banks to conduct cryptocurrency business. In March 2025, OCC abolished the requirement that national banks must obtain no objections from regulators before engaging in cryptocurrency custody and stablecoin business.

Subsequently, in April 2025, the Federal Reserve retracted its guidance that state member banks were required to notify it before initiating crypto-related activities. Banks' expanding operations in areas such as Bitcoin custody, stablecoin issuance, and providing services to exchanges have provided the backdrop for regulators to pay attention to security vulnerabilities at a major crypto platform.

Another incident also affected a traditional lending institution. French bank Credit Mutuel Arkea confirmed on Wednesday that a cyberattack led to fraudulent transfers from its accounts. An investigator on the blockchain estimated the amount stolen to be over $133 million; however, the bank has not confirmed this figure. Credit Mutuel Arkea stated that customer assets were not affected.
