xHelper is a unique Android malware. The malware cannot be removed even after a factory reset. Developers are creating and exploiting existing software. But, it is said that xHelper is one of the most dangerous Android malware. xHelper appeared in October 2019 for the first time. Since then, it has confused researchers. It is claimed to be unkillable.
Why is xHelper unkillable? What is the secret behind it? We are here to answer your questions. So here’s what we know so far. Let’s dwell on it.
The secret behind ‘unkillable’ Android malware ‘xHelper’:
As said earlier, xHelper cannot be removed even after a factory reset. This is because it can hide and reinstall itself, whenever it is removed. Therefore, it is not affected by a factory reset.
Researchers published a detailed report on xHelper in February. However, they weren’t sure about the mystery behind it. But now the secret is out. We can throw light on the topic now.
Kaspersky researcher, Igor Golovin revealed something interesting about Trojan-Dropper.AndroidOS.Helper.h. This appears as a cleaner app for smartphones. Though, it disappears after installation. It is not seen on the main screen.
However, it appears in system settings along with all the installed apps. On installation, Android malware sends personal information to a third-party website. This includes the Android ID, manufacturer, model, etc. It does not stop there. Later, it proceeds to download Trojan modules. Modules are downloaded one after the other. This includes the notorious Triada. Triada roots the devices and allows it to install a series of malicious files directly into the Android read-only system partition.
Triada gives an immutable attribute. This prevents deletion. The android malware, xHelper, drastically affects Android 6 Marshmallow and Android 7 Nougat devices. Kaspersky’s official security blog displays more details about it.
Moreover, Igor Golovin reveals how you can protect your device. The best way is to reflash the phone with different firmware. However, according to Golovin, it is an unkillable infection. It has extraordinary control over a device.
So this was all about the Android malware, xHelper. For more such updates, stay tuned with us.
