ANDROID'S STAGEFRIGHT VULNERABILITY
- Android’s Stagefright Vulnerability
What is Stagefright?
Last month, a security bug was uncovered that affects smartphones using the Android mobile operating system. This vulnerability can be triggered without any user interaction or simply by opening a Multimedia Messaging Service (MMS) text which may lead to the device being compromised.
To check if your Android device is vulnerable to the bug, you can download Stagefright Detector App released by Zimperium, a mobile security company.
What happens to customers affected by Stagefright?
The bug affects the part of the Android operating system that lets a device display media content. A malicious media file potentially pushed to an affected Android device can compromise your device’s security by letting an attacker read or delete data and even activate a device’s camera and microphone without the user’s knowledge.
What is PC mobile doing to protect customers?
Protecting our customers’ information is our top priority. PC mobile has engaged Google and device manufacturers to ensure we are on top of any developments. Manufacturers are currently working on software updates to repair this vulnerability which will be pushed to customers as soon as it is available.
How to protect yourself in the interim:
At this time the extent of this vulnerability is unclear. As a precaution customers can be proactive in the interim and help reduce risk by following the suggestions below:
- Disable the automatic download of MMS messages on your Android device
- Avoid opening text or MMS messages from unknown individuals
- Update your operating system once a patch is available (we will update this page when we have more information)
You should note that by disabling "auto-retrieve MMS" you are not disabling the ability to receive mms messages. You can still download MMS on a per message basis from your most trusted contacts and sources.
