Android Phone Users, beware of ‘System Update’ Malware That Can Steal Your Photos and Messages

Researchers at mobile security firm Zimperiumz Labs have reportedly found that Android-powered smartphones face threats from new malware disguised as critical system updates. New “advanced” malware can steal personal data such as text messages, images and contacts.

You can also take full control of your Android smartphone, according to research firms. In a blog post, Zimperium explains that hackers can remotely execute commands (remote access Trojans) and bugs control the system to perform a variety of malicious actions. This bug is bundled with an Android app called “System Update” that needs to be installed outside of Google Play.

Speaking more over the development, Zimperium CEO Shridhar Mittal told TechCrunch that the malware was likely part of a targeted attack. “It is easily the most sophisticated we’ve seen. I think a lot of time and effort was spent on creating this app. We believe that there are other apps out there like this, and we are trying our very best to find them as soon as possible,” he added. The security firm notes that upon installation (from a third party store), the malware communicates with the operator’s Firebase server – used to control the smartphone remotely.

The collected data is then organised into several folders inside the spyware’s private storage. The “System Update” can even create a malicious notification that might appear to be a legitimate software update alert. “Apart from the various types of personal data stolen from the victim, the spyware wants more private data such as the victim’s bookmarks and search history from popular browsers like Google Chrome, Mozilla Firefox, and the Samsung Internet Browser,” the blog post highlights.

One of the easiest ways to avoid such malicious apps is not to download files outside Google Play Store. Mittal also confirmed to the publication that the malicious “System Update” app has never appeared on Google Play. On the other hand, Google is yet to address the issue publicly.
