Cyberattacks and the Peril of Bank Failures

Cyberattacks and the Peril of Bank Failures

4 Min.

The likelihood of significant cyberattacks targeting banks is increasing. Banks are highly interconnected, which means that if one bank falls victim to a cyberattack, it could spread to other banks and pose a significant risk to their financial stability. State-sponsored cyberattacks pose a high risk to U.S. banks.


With the relentless surge of cyber threats, the specter of a catastrophic bank collapse looms ominously. Virtually all financial institutions have fallen prey to insidious cyberattacks, their frequency spiraling upwards. Alarming statistics reveal that financial firms are subjected to such assaults a staggering 300 times more frequently than their non-financial counterparts, as per the authoritative findings of the Boston Consulting Group.

In this exposé, we delve into the escalating perils confronting banks and explore the profound repercussions that ensue in the wake of a relentless cyber onslaught.

The Rising Risk of Cyberattacks

The haunting specter of a devastating cyber assault targeting banks intensified following the audacious heist of $81 million from Bangladesh's central bank in February 2016. Subsequently, Russian central bank authorities disclosed a staggering theft of over $31 million (equivalent to 2 billion rubles at that time) from the nation's central bank and commercial banks.

During testimony before the House Financial Services Committee in February 2020, Federal Reserve Chair Jerome Powell unequivocally pointed to cybersecurity when asked to identify the most pressing threat to the financial system. Powell emphatically voiced his concerns: "The peril that preoccupies us greatly is cyberattacks. While we possess a robust strategy to combat conventional issues like nonperforming loans, the escalating frontier of cyberattacks is the cause for profound apprehension."

Alarming volumes of attempted attacks already besiege numerous banks annually, leading to moderate losses. However, the disturbing reality is that hackers rapidly evolve, deploying increasingly sophisticated tactics that render banks perilously susceptible to large-scale assaults.

The Vulnerability of Banks: An Unveiling of Risks

Amidst a landscape of intricate interconnections within the banking system, the Federal Reserve Bank of New York, in a report initially issued in January 2020 and subsequently revised in 2021, underscores the substantial peril of spillover effects arising from cyberattacks. Startlingly, the report posits that an assault on any of the five most prominent U.S. banks could impact a staggering 38% of the network.

Security experts issue a dire warning, emphasizing the heightened susceptibility of U.S. banks to state-sponsored cyberattacks orchestrated by formidable adversaries such as Russia, China, and North Korea. "The most significant threat to our financial sector resides in state-sponsored hacking due to the immense capabilities they wield," articulated Jamil Jaffer, founder and executive director of George Mason University's National Security Institute, while testifying before the House Financial Services subcommittee on national security, international development, and monetary policy in June 2020.

A noteworthy statistic reveals that an alarming 63% of financial institutions experienced a surge in destructive cyberattacks from 2021 to 2022, as highlighted in VMWare's comprehensive study titled "Modern Bank Heists 5.0: The Escalation from Dwell to Destruction."

The Impact of Cyberattacks on Customers

Safeguarded by prudent information protection practices and prompt communication with their respective banks, ordinary consumers face minimal jeopardy in the face of customary cyberattacks on financial institutions. U.S. regulations dictate that if customers promptly notify their banks within 60 days of unauthorized transactions appearing on their statements, they must reimburse any funds unlawfully withdrawn. Nonetheless, it is important to note that business accounts lacking similar safeguards are susceptible to heightened losses.

While the Federal Deposit Insurance Corporation (FDIC) extends insurance coverage up to $250,000 for bank deposits in participating institutions, it is crucial to recognize that banks themselves bear no federal guarantee of solvency in the event of a significant cyberattack. These attacks, targeting the core of bank processing systems, can potentially disrupt important financial transactions, precipitating significant repercussions.

The Impact of Cyberattacks on Banks

The ramifications of cyberattacks on banks manifest in diverse ways. Apart from the direct financial losses incurred through the illicit extraction of funds by hackers, banks bear the additional burden of implementing robust cybersecurity measures to safeguard their assets. Moreover, these cyber incursions erode customers' trust in financial institutions, as the fear of monetary theft undermines their confidence in banks' ability to protect their assets. Consequently, the disruptive nature of cyberattacks reverberates throughout the banks' operations, causing profound upheaval and fundamentally altering their operational landscape.

As per the comprehensive 2022 IBM Cost of a Data Breach Report, financial organizations suffer an average loss of $5.97 million per breach, underscoring the staggering financial impact of cyberattacks on banks.

Ransomware, phishing, trojans, and spoofing are primary threats and tactics deployed against banks during cyberattacks. These sophisticated methods pose formidable challenges to the security infrastructure of financial institutions.


The banking sector places great emphasis on cybersecurity. While federal law offers customers protection to recover their funds, there is worry among experts that the increasing frequency of cyberattacks could potentially endanger a large bank's financial stability.
