The McAfee Mobile Research Team is warning Android users about a big security risk. They’ve found 25 apps that are infected with Xamalicious malware, and a bunch of them were on the Google Play Store. These apps cover different types – like games, health stuff, horoscopes, and tools to get stuff done. Google quickly took them down from their Play Store, but you can still find them in other Android app shops out there.
Apple’s Stance on Sideloading
Apple’s opposition to sideloading, often attributed to their desire to collect a 30% commission, is also a stance for security. Apple maintains that sideloading takes apps out of its oversight, increasing the risk of infected apps reaching users’ devices.
Understanding Xamalicious Malware
Xamalicious malware is particularly insidious. It uses social engineering to gain accessibility privileges, allowing infected devices to communicate with a command-and-control server without the owner’s knowledge. A second payload can then be downloaded, taking full control of the device for fraudulent activities like ad clicking and unauthorized app installations, all financially motivated and without user consent.
List of Infected Apps
The infected apps, now removed from the Google Play Store but potentially still present on users’ devices, include:
- Essential Horoscope for Android – 100,000 downloads
- 3D Skin Editor for PE Minecraft – 100,000 downloads
- Logo Maker Pro – 100,000 downloads
- Auto Click Repeater – 10,000 downloads

These apps range widely in popularity, with some having been installed over 100,000 times.
Preventive Measures and User Advisory
Users are advised to check their devices for these apps and uninstall them if found. Symptoms of malware infection include overheating of the phone and rapid battery drainage. The primary goal of the Xamalicious malware is to turn infected phones into revenue-generating tools for cybercriminals.
Technical Insights into Xamalicious
The Xamalicious malware leverages the Xamarin open-source mobile app platform. Its sophisticated approach includes the use of obfuscation techniques and custom encryption to exfiltrate data and communicate stealthily with its command-and-control server.
Action Steps for Android Users
Despite the removal of these apps from Google Play, Google cannot remotely uninstall them from user devices. Users must proactively check their installed apps against the list provided and remove any matches.

Recognizing and Responding to Malware Symptoms
It’s important for users to recognize when their computer might have a malware problem. Look out for stuff like pop-up ads that come out of nowhere, strange charges on your bill, your data vanishing quicker than usual, and your device acting up — slowing down or freezing. If you think your device is infected, don’t wait around. You should quickly run a secure antivirus program, reset your gadget back to how it was when you first got it, or get some help from tech experts.
Safe App Practices
Exercise caution when downloading apps. Always check the developer’s credentials, read user reviews, and scrutinize app permissions. Apps requesting unnecessary permissions for their functionality should raise a red flag. For instance, a simple calculator app should not need access to your contacts or location.
The Role of Tech Companies in Ensuring App Security
Big tech firms such as Google are key players in keeping their app stores safe. They should constantly check the apps they offer, quickly deal with security problems that get reported, and talk openly with their users. These actions are critical in creating a secure online space.
Collaboration with Security Researchers
Tech companies need to work closely with security experts. Groups such as the McAfee Mobile Research Team are integral in finding and sharing information about security dangers. They use their knowledge and alertness to protect the online world for everyone.
To sum it up, finding Xamalicious malware in well-known Android applications is a clear wake-up call in our continuous fight against online dangers. It’s vital for users to stay alert, keep an eye on the apps they have, and follow top-notch guidelines for staying safe online. Click here to know more.
