1. Tracking Phone Motion: Criminals use a device called an accelerometer to track the motion of your phone when you enter your PIN. This device is usually hidden in close proximity to an ATM machine, such as in the keyboard cover or behind a nearby object.
2. Identifying PIN Entry: The accelerometer tracks the unique motion created by the physical contact of your finger with the phone screen. Each person's finger movement pattern is distinctive and creates a characteristic pattern when entering their PIN.
3. Data Recording and Analysis: The accelerometer records the motion data during PIN entry and stores it for analysis. Forensic software is then used to analyze this data and extract details about your PIN. The patterns generated when pressing the screen at specific locations with different levels of pressure help the criminals narrow down the possible combinations until they crack your PIN.
4. Stealing Your PIN: Once the PIN is identified, criminals can use it to make unauthorized transactions or gain access to your bank account. They can also use it to create a fake copy of your ATM card and use it for fraudulent activities.
To protect yourself from this type of PIN theft, be mindful of your surroundings and avoid using public ATMs with suspicious attachments. If you notice anything unusual, it's best to choose a different ATM or seek assistance from a bank representative. Additionally, you should change your PIN regularly and avoid simple or predictable combinations.
