Access Sensitive Data in Device Logs
On versions of Android prior to 4.1, an adversary may use a malicious application that holds the READ_LOGS permission to obtain private keys, passwords, other credentials, or other sensitive data stored in the device's system log. On Android 4.1 and later, an adversary would need to attempt to perform an operating system privilege escalation attack to be able to access the log.

Starting in Android 4.1, this technique requires privilege escalation for malicious applications to perform, as apps can no longer access the system log (other than log entries added by a particular app itself). (Additionally, with physical access to the device, the system log could be accessed via USB through the Android Debug Bridge.)[1] |
