Malicious apps can exploit this functionality by setting the TaskAffinity for one or more of its activities to match a package name of a trusted third-party app. "An attacker can ask for access to any permission, including SMS, photos, microphone, and Global Positioning System, allowing them to read messages, view photos, eavesdrop, and track the victim's movements", researchers John Høegh-Omdal, Caner Kaya, and Markus Ottensmann at app security provider Promon say.
Promon further explains how the malicious app poses as a legitimate one and seeks permissions from the user which are usually accepted.
Promon said that all of the top 500 most popular apps on the Android Play Store are at risk, and all versions of Android are affected.More news: Prosecutors Say They'll Likely Let Parnas Hand Over Docs To Impeachment Inquiry
Promon published a detailed report which reveals that all versions of Android including the Android 10 have been affected and 36 malicious apps that exploit the vulnerability were identified. That omission makes it exhausting for folks to know if they're or have been contaminated. "From here, through its research, Promon was able to identify the malware was being used to exploit a risky Android vulnerability". There is no way to block such an attack, and there is no method for detecting the flaw. Some of those attacks rely on the target device being rooted, but the StrandHogg vulnerability does not.
However, Strandhogg-infected apps don't exist in the Android official App Store Google Play. Also, closing recently opened apps from time-to-time could also help keep you safe, says Promon. After permission is given, the app starts running normally.

Typos and errors within the person interface. So, when the user clicks a trusted app's icon on the screen, a malicious version instead starts.
- Back button does not work as expected. The security firm, in turn, heard about the vulnerability when a number of banks in the Czech Republic told it about incidents of money disappearing from customer accounts.
According to Techradar, Google is aware of the vulnerability, having suspended applications that were identified as malicious.

The malware sample Promon analyzed was installed through several droppers apps and downloaders distributed on Google Play. Various mobile app security technologies under the umbrella of in-app protection, including app shielding and runtime protection make it easier for app developers to mitigate these windows of exposure resulting from security issues in both Android and iOS.
