In a study conducted by security research firm Zscaler, 28% of Android apps request permission to read old SMS logs, while a whopping 68% request permission to send SMS messages from your phone. They also found that 36% of apps request GPS permissions, while over 46% request access to the “phone’s state”, allowing the app to gather information related to the SIM card, IMEI number, serial number and more. For the study, Zscaler analyzed over 75,000 apps from the Google Play store and logged the requested permissions from each app. Being a security firm, Zscaler considers SMS and GPS related permissions to be the two most “high risk” permissions to grant access to, with “device information related permissions” landing sixth on the list.
