Proof of Concept
Android system logs where Norton Mobile Security Beta sensitive information is stored. Some applications downloaded to an Android Smartphone may be able to gain unnecessary and/or unauthorized read/write access permission to device logs without the consent or knowledge of the device owner.
An individual could potentially create a malicious application that can gain unauthorized access to sensitive Norton Mobile Security Beta information stored on device system logs. An attacker would have to effectively entice the user to download the hostile app by visiting a malicious web site or by clicking on a malicious URL. The user would need to authorize the permissions required and requested by the app in most instances though the app may be able to circumvent actual user authorization is some instances.
Such an attack could potentially expose application setup information to possibly include the wipe/lock credentials the user established for the Norton Mobile Security Beta application. This could possibly result in a malicious user being able to be able to deny the user access to the phone or potentially manipulate personal data stored on the phone via specifically formatted messages.
Symantec product engineers have developed and released a solution. Symantec Mobile Security Beta for Android users should updated to the latest release available through normal update procedures.
Symantec knows of no exploitation of or adverse customer impact from this issue.
As part of normal best practices, Symantec strongly recommends:
Keep Smartphone operating systems and applications updated with the latest vendor patches
Run an anti-malware application to provide detection and protection to both inbound and outbound threats
Users should be cautious of unknown applications or applications from sites they are not familiar with or of questionable reputation
Be wary of attachments and executables delivered via email or IM and be cautious of browsing unknown/untrusted websites or clicking on unknown/untrusted URL links
Be aware of and understand the impact of permissions being requested by the app being download before granting access
