It is critical to be informed of potential vulnerabilities and strengthen your defenses against unnecessary risk.



Here's a breakdown of the 10 most common attacks:


Physical Attacks & Theft Devices:


1. Tow & Hook: A truck aligns to the ATM in a “T” formation. The thief attaches a chain and hook to the ATM and uses the truck’s strength to rip off the front and steal interior currency.


2. Cash-Out Attack: Criminals remove the ATM outer shell, hand off the hard drive to a waiting coder who installs an executable code, and sets a command for the ATM to dispense all internal currency as soon as it is replaced.


3. Jack Potting: Similar to Cash-Out, the criminal uses other types of physical access to an ATM and installs malware on the machine via an open port (USB or Ethernet). The sophisticated malware scans and then takes advantage of the ATM’s software vulnerabilities and commands it to dispense all the cash in the internal cassettes. This type of theft is not tied to a card or any specific account but to all the cash within the ATM and can be devastating to a financial institution.


Other Forms of Jack Potting:


4. Man-in-the-Middle (MITM): Attackers place a device between the ATM and the host computer to intercept, eavesdrop, modify, or impersonate communication for fraudulent purposes without need to access the ATM casing. Often accessed via the cables that are connected to the bank and larger services this is a significant risk.


5. Black Box Attack: Black Box devices are small, portable electronic devices often built around a single-board computer that exploit security weaknesses. The black box either connects directly to the cash dispenser, bypassing controls and stealing money, or takes advantage of software flaws to gain control of the entire ATM. These devices are becoming readily available on the black market, and rising in use by organized crime rings which is raising concerns that these attacks could become more widespread. Their stealthy nature makes them difficult to detect in real-time, allowing criminals to steal very large sums quickly.

Card & Data Stealing Threats:


6. Skimming/Shimming (also known as a Deep Insert Skimming): Criminals install a fake card reader or wafer-thin device onto or within the ATM. Difficult to detect, the device steals your card's data directly from the magnetic stripe. However, although it steals card data it cannot access the PIN. Criminals often use hidden cameras on the ATM fascia to capture the PIN as users enter it.


Preplanned Street Theft:


7. Shoulder Surfing: Nefarious actors use stealthy methods to steal PIN data from unsuspecting ATM users. They may follow the user and steal the card at another location (assault, purse snatching, pickpocketing or even home invasion), and then return to the ATM to empty the user’s accounts. Then there is a rise in ATM muggings. Rather than follow the user to steal the card at another location, the bad actor threatens the user while using the ATM and forces them to access and drain accounts.


8. Glue and Tap Scam: This involves criminals tampering with the card reader by placing something inside it that blocks card insertion. The criminal then acts as a helpful bystander who suggests using the tap-to-pay option. Since tapping often bypasses the log-out function, fraudsters can steal money from the active session once the customer leaves the vicinity.


9. Service Call Exploitation: In some cases, thieves might create fake service requests to lure technicians to a specific ATM. This could be a way to distract them or create an opportunity for a robbery.


Network and Cyber Attacks:


10. Phishing and Vishing: Fraudsters might contact an email list of victims and pretend to be a legitimate vendor. They request sensitive information under the guise of a security check. Sometimes, the more sophisticated thieves will employ an email phishing scheme targeted to a specific user they have researched. Referred to as “Spear Phishing”, the perpetrator curates a custom and very realistic “corporate” email that encourages the user to enter personal data in response to a recent transaction or activity. He or she then withdraws from the user accounts before the theft is recognized as illegitimate.
