Protected User Data: Contact List

Adversaries may utilize standard operating system APIs to gather contact list data. On Android, this can be accomplished using the Contacts Content Provider. On iOS, this can be accomplished using the Contacts framework.

If the device has been jailbroken or rooted, an adversary may be able to access the Contact List without the user’s knowledge or approval.

Mitigations

ID Mitigation Description
M1011 User Guidance

Contact list access is an uncommonly needed permission, so users should be instructed to use extra scrutiny when granting access to their contact list.

Detection

ID Data Source Data Component Detects
DS0041 Application Vetting Permissions Requests

Application vetting services could look for android.permission.READ_CONTACTS in an Android application’s manifest, or NSContactsUsageDescription in an iOS application’s Info.plist file. Most applications do not need contact list access, so extra scrutiny could be applied to those that request it.

DS0042 User Interface System Settings

On both Android and iOS, the user can manage which applications have permission to access the contact list through the device settings screen, revoking the permission if necessary.
