The automated teller machine, or ATM, represents a meeting point between tradition and innovation, a symbol of our daily economic life. In a context like Italy and the Mediterranean, where cash retains a cultural and practical value, the ATM is more than just a banknote dispenser: it’s an essential service that combines digital convenience with the tangibility of money. However, this familiarity hides real risks. ATM fraud is constantly evolving, using increasingly deceptive technologies. Knowing the threats, such as skimming and phishing, and adopting simple yet effective preventive measures is crucial to protecting your savings and using these tools with peace of mind.
Although fraud cases have a limited incidence compared to the total volume of transactions, the phenomenon remains insidious. According to data from the Bank of Italy, the fraud rate for ATM withdrawals is relatively low, but the very nature of the attacks makes them a danger that should not be underestimated. Statistics show that cyber and online fraud are on the rise, with a significant economic impact on citizens. Understanding criminals’ strategies is the first line of defense for every user, regardless of age or technological proficiency.

The Most Common ATM Threats
ATM security is threatened by a range of fraudulent techniques, from physical tampering to sophisticated cyberattacks. The best-known threat is probably skimming, which involves cloning the card using illegal devices installed on the ATM. Alongside this are cash trapping, a physical trap to block banknotes, and phishing (or vishing when done by phone), which aims to steal credentials through deception. There are also more complex attacks, such as those based on malware, known as “jackpotting,” which order the machine to dispense cash illegally. Recognizing the signs of these threats is the first step to a safe withdrawal.
Skimming in Detail: How It Works and How to Spot It
Skimming is one of the most common scams and involves stealing your card’s data. Criminals install a device, called a skimmer, over the card slot. This device, often identical in appearance to the original, reads and stores the information on the magnetic stripe. To steal the PIN, scammers pair the skimmer with a micro-camera, hidden in a fake panel above the keypad, or a false keypad placed over the real one. With these two pieces of information, criminals can clone the card and use it for fraudulent withdrawals or purchases. The key to protecting yourself is careful observation before every transaction.
Recognizing a tampered ATM takes just a few seconds of attention. Before inserting your card, check the slot: if it looks bulky, loose, or has signs of glue, it could be a skimmer. Try to wiggle it slightly; the original component is always fixed. Next, examine the keypad: if the keys feel “spongy,” raised, or if the entire plate moves, it might be hiding a device to record your PIN. Finally, look for small, suspicious holes above or next to the screen, which could hide a micro-camera. And a golden rule: always cover the keypad with your hand while entering your secret code. If in doubt, don’t use the machine and notify the bank.
Phishing and Vishing: Remote Scams
Not all threats require physical tampering with the ATM. Phishing and vishing are social engineering techniques that use deception to extort sensitive information. In phishing, scammers send emails or text messages (in this case, it’s called smishing) that appear to be from your bank, inviting you to click a link or provide data. Vishing, or voice phishing, is even more insidious: a fake bank representative contacts you by phone, often with the excuse of a security problem with your account or card. They might even use “spoofing” to make the bank’s real number appear on your phone.
The goal of these attacks is always the same: to convince you to reveal personal data such as your card number, online banking passwords, or, most importantly, security codes (PIN and OTP). The call often has an alarmist tone to push you to act impulsively without thinking. The State Police and banking institutions are clear: no bank will ever ask you to provide your secret codes by phone or email. If you receive such a communication, end the contact immediately and, if in doubt, call your bank yourself using the official numbers.
Other Fraud Techniques: From “Cash Trapping” to Malware
Besides skimming, there are other physical fraud techniques. One of these is cash trapping. Criminals attach a fake dispenser cover or insert a metal fork into the slot where the banknotes come out. When you make a withdrawal, the money is dispensed by the machine but gets trapped in the device. Convinced it’s a malfunction, you walk away to seek help, at which point the scammer approaches to retrieve the trapped money. If an ATM doesn’t dispense cash, never walk away and immediately contact your bank and law enforcement.
The most sophisticated attacks are logical ones, which target the ATM’s software. Jackpotting is a technique that, through the installation of malware, forces the machine to dispense all the cash it contains, like a slot machine that has hit the “jackpot.” The infection often occurs with physical access, via a USB port. Another method is the “black box” attack, where criminals disconnect the ATM’s computer and connect their own device directly to the cash dispenser to send the command to eject the banknotes. These attacks are complex, but they show how crime adapts to overcome physical defenses.
Prevention: Your First Line of Defense
The best defense against fraud is careful and conscious behavior. Adopting a few simple habits can drastically reduce the risk of falling into a trap. Before each transaction, take a few seconds to inspect the machine, as described earlier, looking for anomalies. Prefer ATMs located inside bank branches or in well-lit, supervised areas, as they are less easy targets for criminals. When entering your PIN, always shield the keypad with your free hand or your body to block the view of any hidden cameras.
Another good practice is to activate the SMS or app notification services offered by your bank. Receiving a real-time alert for every transaction allows you to immediately spot any unauthorized withdrawals. Regularly check your bank account statements to quickly notice any suspicious charges. If your card is retained by the machine, don’t immediately assume it’s a malfunction. It could be a fraud attempt. Do not walk away and immediately contact the toll-free number to block your card. Adopting these precautions is essential, especially when you’re faced with a blocked or cloned card at the ATM and need to know what to do right away.
The Evolution of Security: Banks and Technology
As criminals refine their techniques, the banking sector is also constantly investing in innovation to protect customers. European regulations, such as the Payment Services Directive (PSD2 and the future PSD3), have introduced higher security standards, like Strong Customer Authentication (SCA), which requires two or more verification factors (e.g., a PIN and a code via an app) to authorize transactions. Modern ATMs are also equipped with anti-skimming devices, which make it harder to install fraudulent card readers, and security software that protects against malware attacks.
Innovation is also changing how we interact with these machines. Technologies like cardless and NFC (Near Field Communication) withdrawals are becoming increasingly popular. These methods allow you to withdraw cash using your smartphone, without having to physically insert the card, thus eliminating the risk of skimming at its source. At the same time, smart ATMs are becoming more widespread—advanced machines that offer an ever-expanding range of services beyond simple withdrawals, transforming the ATM into a true digital access point to the bank, with increasingly robust integrated security standards.
Conclusion

ATM security is a shared responsibility. On one hand, banks and European institutions work to implement increasingly stringent technologies and regulations to combat fraud. On the other, every user has an active role to play. Awareness of the risks, combined with the adoption of simple but fundamental prevention practices, represents the most powerful defense against skimming, phishing, and other threats. Inspecting the machine, protecting your PIN, being wary of suspicious communications, and monitoring your account are actions that turn a daily habit into a safe one. In a world where finance is increasingly digital, staying informed and acting with caution allows you to fully leverage the benefits of innovation, while upholding the tradition of security and trust that connects citizens to their financial institutions.
Frequently Asked Questions

Before making a withdrawal, always inspect the ATM. Look for suspicious elements like bulky, loose, or unusual parts on the card slot and keypad. If the card slot wiggles or seems thicker than normal, it could be hiding a “skimmer” to clone your data. Similarly, if the keypad feels “spongy” or the keys are hard to press, it might be a cover to record your PIN. Another red flag is the presence of small holes or unusual objects near the screen, which could hide micro-cameras. Always cover the keypad with your hand while entering your PIN.
If the ATM doesn’t dispense the banknotes after the transaction, don’t walk away immediately. It could be a scam called “cash trapping,” where a device blocks the money from coming out. Check the cash dispenser slot to see if you notice any abnormalities or if the bills are visible but stuck. Immediately contact the bank’s customer service number, usually listed on the ATM itself, and report the problem. Note the ATM’s ID number, date, and time to file a report if necessary. Never accept help from strangers who offer to solve the problem.
Card cloning means that criminals have illegally copied the data from your magnetic stripe and your PIN to create a duplicate and use it for unauthorized withdrawals or purchases. You’ll notice it by checking your bank statement and seeing suspicious transactions. The first thing to do is to block the card immediately: call your bank’s 24/7 toll-free number. Next, file a report with law enforcement and send a copy of the report to your bank to start the reimbursement process for the stolen funds.
Yes, it is generally considered safer to use ATMs located inside bank branches or in well-lit, supervised areas. Outdoor and isolated ATMs are easier targets for scammers, who can install skimming or cash-trapping devices with less risk of being discovered. Bank branches often have more effective video surveillance systems, and staff can more easily notice any tampering.
Yes, they exist and fall into the category of “phishing” or “smishing.” Scammers send emails or text messages pretending to be your bank, warning you of alleged security issues with your account or card. These messages invite you to go to an ATM to perform “unlocking” or “verification” procedures, following instructions that are actually designed to transfer money to their account. Remember that your bank will never ask you to perform operations at an ATM via a link received by email or SMS, nor will it ever ask for your credentials or security codes.
