Security Experts Reveal that Smartphone sensors can be spying your mobile phone and steal the PINS and password by cyber criminals.This Technique mostly Target by the Malicious apps installations which can possibly capture the user movements by motion sensors.

Security Experts from Newcastle University Explained, Analysing the movement of the device as we type in information, they have shown it is possible to crack four-digit PINs with a 70% accuracy on the first guess – 100% by the fifth guess – using just the data collected via the phone’s numerous internal sensors.t the additional risks posed by personal fitness trackers which are linked up to our online profiles

The additional risks posed by personal fitness trackers which are linked up to our online profile and potentially spying the credentials by using the physical activities such as sitting, walking, running.

Dr Maryam Mehrnezhad  explained,

“Most smartphones, tablets, and other wearables are now equipped with a multitude of sensors, from the well-known GPS, camera, and microphone to instruments such as the gyroscope, proximity, NFC, and rotation sensors and accelerometer.

“But because mobile apps and websites don’t need to ask permission to access most of them, malicious programs can covertly ‘listen in’ on your sensor data and use it to discover a wide range  of sensitive information about you such as phone call timing, physical activities and even your touch actions, PINs and passwords.”

Access without permission:

There are 25 different sensors which now come as standard on most smart devices and are used to give different information about the device and its user.

The study found that each user touch action – clicking, scrolling, holding and tapping – induces a unique orientation and motion trace.  So on a known web page, the team were able to determine what part of the page the user was clicking on and what they were typing.

Researchers Said ,“Depending on how we type – whether you hold your phone in one hand and use your thumb, or perhaps hold with one hand and type with the other, whether you touch or swipe – the device will tilt in a certain way and it’s quite easy to start to recognise tilt patterns associated with ‘Touch Signatures’ that we use regularly.”

So How to Protect From this Type of Attacks

According to the Newcastle University’s Researchers,

  • Make sure you change PINs and passwords regularly so malicious websites can’t start to recognize a pattern.
  • Close background apps when you are not using them and uninstall apps you no longer need
  • Keep your phone operating system and apps up to date
  • Only install applications from approved app stores
  • Audit the permissions that apps have on your phone
  • Scrutinize the permission requested by apps before you install them and choose alternatives with more sensible permissions if needed.
