SpinOk software attacks users through mini-games and daily rewards. Users who think they can earn money by spinning a wheel or claiming daily rewards fall victim to this malicious software. Operating as an advertising kit in the background, SpinOk also utilizes the device’s sensor data.
The Trojan horse establishes a connection with a remote server to download the mini-games. Despite offering these games to users, it also carries out a range of malicious activities, including searching for specific files, listing directory contents, copying clipboard data, and even uploading files to the device.
