Banking Cybersecurity Challenges: Safeguarding Financial Institutions in 2025

By 2025, the banking industry will continue its rapid progression into the digital era, leaving behind the days when physical visits to a local branch were the norm for tasks like cashing or depositing checks. Today, nearly all transactions can be conducted online via a bank’s mobile application or website, making data security in the banking industry a critical concern.

A recent survey by the Financial Services Information Sharing and Analysis Center (FS-ISAC) reveals that 89% of financial institutions increased their cybersecurity budgets in 2024 and beyond, underscoring the urgent need to address ever-evolving cyber threats. Despite the implementation of advanced security measures, cybercriminals’ growing sophistication demands constant investment and innovation in cybersecurity.

In this post, we’ll explore the state of cybersecurity in banking in 2025. Topics include:

• The importance of adhering to cybersecurity trends;
• Current cybersecurity challenges in banking;
• Emerging cybersecurity trends in financial institutions;
• High-profile cases of banking cyberattacks;
• Practical steps to secure banking institutions.

What is Cybersecurity in Banking Sector?

Cybersecurity in the banking sector refers to the measures and technologies employed by financial institutions to protect against unauthorized access, cyber threats, and data breaches.

The “cybersecurity” system, guidelines, and techniques are designed to protect against threats, potential harm, computer viruses, malware, hacking, information theft, and unauthorized access to networks, computers, applications, and documentation.

The main objective and importance of cybersecurity in banking are to protect the user’s assets. Additional activities or money transfers are moving online as more people abandon cash. Customers process transactions utilizing digital methods of payment, such as bank cards and online applications, which must be secure.

Pro note: Security compliance is obligatory for financial institutions, fintech firms having digital products that deal with customers’ sensitive personal or financial data, and other similar businesses. Failure to comply with, for example, PCI regulation can result in fines for being non-compliant, ranging from $500,000 per case.

The Importance of Being Aware of Cybersecurity Trends

Cybersecurity is not just important for IT organizations; it is essential for all companies. On a daily basis, banks process billions of money transfers. As a result, it is critical to implement bank data security and control measures to protect their data from cyberattacks. Here are some of the effects of security issues in the banking industry and how cybersecurity may help.

1. Customer detriment. When a customer suffers a loss due to credit card theft, it is usually possible to recover it from the bank. However, it takes time to recover the finances in cases such as data violations, which is very concerning for customers. Every bank must implement cybersecurity methods to protect their customers’ data to keep their data safe.
2. The bank’s reputation may be undermined. Data infringement is a critical issue for banks because it results in the loss of user data. Customers will lose trust in a bank if their personal information is compromised. Data breaches are typically the result of inadequate cybersecurity measures.
3. Quick advancement of fraud means. Banks must advance their customer-facing banking activities, as in today’s world, hackers can quickly gain access to financial applications if good cyber security measures are not implemented.

Cybersecurity Challenges Banks Face

It can be difficult to implement prevention methods for cybersecurity banking. Among the major challenges that banks must overcome are:

1. Expertise shortfall: There is a notable gap in cybersecurity expertise within the banking industry, where the demand for properly qualified professionals greatly exceeds the available supply.
2. Inadequate training: Many bank employees are insufficiently educated on the importance of cybersecurity. Training is often outdated, failing to cover new threats and cyberattack tactics that target the financial sector.
3. Budget constraints: Banks often face limited budgets to dedicate to cybersecurity measures, complicating efforts to sufficiently protect against evolving threats.
4. Weak credentials: The use of weak passwords by bank employees simplifies the process for cybercriminals attempting to breach bank security systems.
5. Mobile vulnerabilities: Cybercriminals increasingly target mobile banking apps and devices, exploiting their vulnerabilities to conduct unauthorized transactions and data breaches.

The Top Cybersecurity Threats in 2025 for Banks

Listed below are the top cyber threats to a financial sector that are expected to keep wreaking havoc on financial organizations and banks in 2025.

#1 Ransomware

Over the past few years, ransomware has become a significant challenge for businesses globally, with no signs of abating anytime soon. This is a cybercrime technique in which documents are encrypted, and clients are locked out, with the fraudsters demanding money to re-enter the system.

Companies hit by ransomware cyber attacks on banks may find their services paralyzed for prolonged periods, especially if they lack backups. Paying a ransom to these criminals does not ensure that your system access will be restored.

#2 Unencrypted Data

It is one of the most common banking security threats faced by financial institutions. When data is left unencrypted, computer hackers use it immediately, causing serious problems for the banks. All data stored on PCs in banking institutions or digitally should be entirely encrypted. This will ensure that hackers cannot use it, whether or not the data is stolen.

#3 Common Cloud-Based Cyber Attacks

Since more statistics and crucial information are kept in the cloud, cybercriminals have taken advantage of this. As a consequence, cloud-based threats are now one of the most prevalent cybersecurity threats in the the banking industry. Banks should ensure that their cloud infrastructure is safely arranged to prevent harmful infringements.

#4 Social Engineering

Social engineering is one of the most serious threats to finance and banking. People are frequently the weakest component of the security chain, as they can be duped into disclosing sensitive information and credentials. This can affect both bank employees and customers.

Social engineering can take many forms, including phishing and whaling attacks and mailing false invoices that appear to have been sent from a reliable source. It is critical to keep your employees updated on social engineering methods and how such attacks emerge.

#5 Supply Chain Attacks

Cybercriminals are increasingly targeting software companies and delivering malicious files to users and other supply network members in the form of services or updates that seem credible on the surface. These banks cyber attacks compromise the supply chain, allowing cyberattackers to access the networks of the vendor’s clients.

Examples of Cybersecurity Attacks in Banks

Over the last few years, banks have had numerous data breaches. Here are a few examples of cyber attacks on banks:

• Ransomware attack on ICBC: In November 2023, ICBC USA was hit by a ransomware attack. Attackers encrypted files and demanded a ransom, threatening to release sensitive customer data if not paid​.
• DDoS attacks on US financial services: The US financial services faced numerous DDoS attacks in 2023. These attacks disrupted services by overwhelming systems with traffic, highlighting the sector’s vulnerability.
• Data breaches exploiting MOVEit vulnerabilities: In 2024, breaches via MOVEit vulnerabilities impacted millions. Incidents included a massive breach of Ontario’s birth registry and a significant data leak at IBM, affecting millions of healthcare records​.
• Royal mail ransomware attack: Royal Mail in the UK suffered a ransomware attack in January 2023 by LockBit, which disrupted international shipments and started with an Emotet malware infection.

As can be observed, despite the advancement of security tech, there are still many successful fraud attack cases. So, keeping cybersecurity measures relevant is key.

How to Make Banking Institutions Cyber Secure?

Securing banking institutions against cybersecurity threats requires a proactive and multi-layered approach. As Artur Nesterenko explains:

The financial sector must adapt to the evolving threat landscape by investing in technology, education, and partnerships to stay resilient.

Here are key strategies banks can adopt to enhance cybersecurity:

1. Overcoming the labor shortage through collaboration Banks often face a shortage of skilled cybersecurity professionals. Collaborating with managed service providers and security associates can bridge this gap. These partnerships offer access to specialized expertise and advanced technologies, ensuring consistent monitoring and swift responses to threats.
2. Incorporating ongoing training for cybersecurity awareness Regular employee training is essential to address human error, a leading cause of breaches. Training initiatives must be continually updated to stay relevant to emerging threats. Employees equipped with current knowledge can effectively identify and mitigate phishing attempts and social engineering tactics.
3. Investing in advanced detection and protection tools Detection tools powered by artificial intelligence and machine learning help banks monitor and respond to potential threats in real-time. These tools strengthen defenses by identifying unusual behavior patterns and mitigating risks before they escalate.
4. Customer education programs Customers are often targeted by cybercriminals, making their education critical. Financial institutions should provide guidance on recognizing phishing scams, protecting login credentials, and verifying communication sources. Nesterenko highlights:

Empowering customers with knowledge transforms them from a vulnerability into an active line of defense.

By integrating these strategies, banking institutions can address the cybersecurity challenges in banking, reduce vulnerabilities, and foster trust within the financial ecosystem.
