Malicious actors are targeting users of a mobile currency game by using fake Android and Windows software that installs spyware and other malware.

Hamster Kombat launched in March and already has more than 250 million users, likely due to the promises of winning TON-based cryptocurrency. The game is for Android users, who can earn in-game currency by completing certain tasks within the game.

To play, users must join the game’s Telegram channel, scan a QR code, and then launch a Web app on their device. When users first search for the game’s Telegram channel, they are likely to come across other Hamster-branded channels attempting to distribute Android malware. One channel, named “HAMSTER EASY,” even distributes Ratel Android spyware as an APK file.
