Since the sensors inside the phone do not need user permissions for storing data and are always open for being accessed by apps, therefore, these can easily jeopardize phone’s security. The team opined that the discovery highlights a critical flaw in smartphone security that is posed by the built-in sensors. Redĭots signalize the time where the display was touched, while green dots signal theįinally, they managed to guess the PIN code with 100% accuracy, which is a ground-breaking discovery since previously in a similar research the Newcastle University, UK, researchers could guess PIN code of a smartphone with 70% accuracy. 10 records where the keys 0-8-5-2 were pressed for two different sensors.
The smartphone they tested had one of 50 most commonly used PIN codes. They noted that when combined with the accelerometer, the gyroscope gave much accurate information and the team hit 10,000 4-digit combos of codes every time. The team tested six sensors including the magnetometer, accelerometer, gyroscope, ambient light sensor, barometer and proximity sensor. Researchers tried to identify the PIN code through exploiting sensors installed inside Android smartphones by letting three people enter a varied range of 4-digit number sequences (about 70 times) randomly and then applied machine learning to the sequences in order to predict the pin code. They were able to correctly guess the 4-digit PIN code for the device. It is worth noting that the researchers tested the method thrice and monitored the data from six sensors installed on an Android smartphone. Researchers found that 99.5% of the time the method worked and their device got unlocked. Apparently, researchers at Singapore based Nanyang Technology University or NTU Singapore, have identified a brand new way with which cyber-crooks can compromise a smartphone, which involves the use of device’s sensors.īelieve it or not but the very own sensors of a smartphone could provide cyber-criminals the key to cracking your device.
Smartphones have remained the primary domain of experimentation for cybercriminals as they are always finding out ways to exploit and crack smartphones mainly Android devices.
