ATMs are critical infrastructure for banks

Despite all the digital money trends and cashless transactions, ATMs (Automated Teller Machines) play a vital role in modern banking. Especially on the markets, where traditionally end-clients prefer extracting money when the salary hits the salary account.

ATMs allow customers to access cash and perform basic banking transactions 24 hours a day, 7 days a week, without needing to visit a physical bank branch. This convenience has made ATMs an essential service for millions of people worldwide.

For banks, ATMs are not only a key customer service point but also a significant revenue generator. Every time a customer uses an ATM, the bank typically charges a transaction fee.

According to Statista, the average ATM fees charged by banks in the United States rose significantly between 1998 and 2023. In 1998, ATM fees were less than two U.S. dollars. After that, fees increased almost annually, reaching a record high of 4.73 U.S. dollars in 2023.

So, as you see, these fees can add up to substantial amounts, especially for banks with large ATM networks. ATMs also help banks reduce costs by automating many teller tasks, allowing them to serve customers with fewer staff and smaller branch footprints.

Vast majority of ATMs have tremendous security vulnerabilities

Despite their importance, a staggering 85% of ATMs are vulnerable to attacks. This is primarily due to outdated software and hardware that can be easily exploited by criminals.

Many ATMs still run on old, unsupported versions of Windows like XP or Windows 7. These operating systems no longer receive security updates from Microsoft, leaving them exposed to known vulnerabilities. Hackers can use these flaws to break into ATMs and install malware that steals customer data or dispenses cash.

“We are often asked, if NetXMS ATM monitoring works on ATMs with Windows XP or Windows 7. And for us it is important to note that yes, it does! Vast ATM fleets usually have machines of different age and caliber, and we try to always accommodate our clients’ requests.”

Victor Kirhenshtein, the CEO of NetXMS

ATM hardware vulnerabilities

ATM hardware is also a weak point. Criminals physically tamper with ATMs to install card skimmers that steal customer card data and PINs.

They can also exploit USB ports or network interfaces to access the ATM's internal systems.

ATMs are prime targets for criminals

According to the CFCA’s Global Fraud Loss Survey 2023, in 2023, there were over 18,000 physical attacks on ATMs globally. In a criminal’s eye ATM attacks can be highly lucrative.

In just a matter of minutes, a successful attack can net thieves thousands of dollars in cash. And the combination of lax security and the promise of quick cash makes ATMs a very appealing target.

Beyond simple theft, compromised ATMs can also be used for more sophisticated crimes like money laundering or identity theft.

Criminals can use stolen card data to create cloned cards and drain accounts. They can also sell this data on the dark web to other fraudsters.

Why are ATMs important?

So why are ATMs still so important in the digital age? Despite the rise of online and mobile banking, many people still rely on ATMs for their daily cash needs.

This is especially true in developing countries where access to traditional banking services may be limited.

The attackers used malware to bypass the ATM withdrawal limits and move money to foreign accounts. This sophisticated attack highlights the importance of robust monitoring to detect and block suspicious activity in real-time.

2. Identify and Patch ATM Network Vulnerabilities

ATMs rely on complex network infrastructure to communicate with banks' core systems. However, these networks often have inherent vulnerabilities that criminals can exploit to gain unauthorized access.

Common weaknesses include unsecured wireless connections, outdated software, and unpatched operating systems.

Regular vulnerability scanning is crucial for identifying and remediating these weaknesses before they can be exploited.

Automated tools can continuously monitor ATM networks for known vulnerabilities, configuration errors, and compliance gaps.

Patch management processes ensure that software updates and security patches are promptly applied to all ATMs to close any potential entry points for attackers.

3. Ensure Regulatory Compliance

Banks face an ever-growing list of regulations and industry standards designed to protect consumer data and prevent financial crimes. Failure to comply can result in hefty fines, reputational damage, and even criminal charges.

For example, the Payment Card Industry Data Security Standard (PCI DSS) requires banks to implement strict security controls for ATMs that process card payments.

These include encrypting cardholder data, restricting physical access to ATMs, and regularly testing security systems.

“NetXMS system works only with encrypted data — cardholders’ data is not received by the system. Our clients successfully certified their NetXMS ATM monitoring on-premise installations, receiving PCI DSS certifications.”

Comprehensive ATM monitoring helps banks demonstrate compliance by providing detailed audit trails and real-time alerts for any deviations from established policies.

4. Protect Sensitive Customer Data

ATMs handle some of customers' most sensitive personal and financial data, including card numbers, PINs, and account balances. A single data breach can expose this information to criminals, leading to identity theft, fraudulent transactions, and long-term damage to customer trust.

End-to-end encryption is essential for protecting data as it travels between ATMs and bank systems. Monitoring solutions should track encryption status and alert on any lapses or anomalies.

Access controls, both physical and logical, ensure that only authorized personnel can interact with ATM components and data.
