![]() ![]() ![]() Simply put, legitimate photo and wallpaper apps simply won’t ask for those because they’re not necessary for such apps to run. However, it’s important to pay attention to apps that request SMS-related permissions and Notification Listener permissions. Further, using McAfee Mobile Security can detect such threats and protect you from them via its regular updates. The McAfee Mobile Research team continues to monitor these threats and protect customers by analyzing potential malware and working with app stores to remove it. We expect that threats which take advantage of Notification Listener will continue to flourish. Leaked data Further threats like these to come? When the notification has arisen from the default SMS package, the message is finally sent out using WebView JavaScript Interface.Īs a result of our additional investigation on C2 servers, following information was found, including carrier, phone number, SMS message, IP address, country, network status, and so forth-along with auto-renewing subscriptions:įigure 7. Like a chain system, the malware then passes the notification object to the final stage. The malware hijacks the Notification Listener to steal incoming SMS messages like Android Joker malware does, without the SMS read permission. However, servers do not always respond to the request or return the secret key.Īs always, the most malicious functions reveal themselves in the final stage. When the server responds “URL” value, the content in the URL is used instead of “2.png”. Also, this malware has self-update function. ![]() And the server returns the key as the “s” value of JSON. It requests keys from the servers for the AES encrypted second payload, “2.png”. Interestingly, this malware uses key management servers. The first payload creates HTTP POST request to the C2 server. The “1.png” is encrypted using RC4 with the package name as the key. apk opens “1.png” file in the assets folder, decrypts it to “x,” and then loads the dropped. Firstly, the hidden malicious code in the main. The figure above shows the decryption flow. Encrypted resource sneaked into the assets folder Encrypted payloads of malware appear in the assets folder associated with the app, using names such as “cache.bin,” “settings.bin,” “data.droid,” or seemingly innocuous “.png” files, as illustrated below.įigure 3. In terms of details, the malware embedded in these apps takes advantage of dynamic code loading. The McAfee Mobile Research team continues to monitor this threat and is likewise continuing its co-operation with Google to remove these and other malicious applications on Google Play. McAfee Mobile Security detects this threat as Android/Etinu and alerts mobile users if they are present. While apps go through a review process to ensure that they are legitimate, these fraudulent apps made their way into the store by submitting a clean version of the app for review and then introducing the malicious code via updates to the app later.įigure 2.

USB Type-C is becoming increasingly common in new smartphones and tablets, but it’s always advisable to check your device’s specifications to determine its USB connectivity options.Authored by: Sang Ryol Ryu and Chanung PakĪ new wave of fraudulent apps has made its way to the Google Play store, targeting Android users in Southwest Asia and the Arabian Peninsula as well-to the tune of more than 700,000 downloads before detection by McAfee Mobile Research and co-operation with Google to remove the apps. You’ll also need a USB Type-C to HDMI adapter, a docking station like our MiraDock that supports video output, a lapdock such as the MiraBook or a USB Type-C-compatible monitor. This mode enables the USB Type-C port to carry a DisplayPort signal, which can then be used to connect to an external screen or monitor. If you want to connect your device to an external display and use Taskbar in Android desktop mode, you’ll need a smartphone that supports “DisplayPort Alternate Mode” or “DP Alt Mode”. However, it’s always advisable to check the application’s compatibility list on the Google Play Store or on the application’s official website to make sure it’s compatible with your mobile. As a general rule, if your device is running Android 7.0 or later, it should work with Taskbar. Taskbar is compatible with a wide range of Android smartphones and tablets. If your smartphone is not included in the aforementioned list, we recommend utilizing Taskbar as an alternative solution. ![]()
