Once installed, the malicious application operates as a stager responsible for acquiring permissions from the user, downloading, and installing a second-stage malware with the capability to take control of the device. It can perform fraudulent actions, such as clicking on ads and installing apps without user consent.
The malware has a self-update function that enables a wide range of threats, including serving as an access broker for the deployment of additional malware, information stealing, and banking trojan-like activities. However, the main malicious activity observed so far appears to be operating as a bot to perform revenue-generating clicks without any actual user interaction.
Reports suggest over 300 thousand devices have been affected globally.
