Top 6 takeaways:
🌍 The game has gained significant traction among cryptocurrency enthusiasts, with claims of 150 million active users and plans to launch a new crypto coin token.
😈 Cybercriminals are exploiting the game’s popularity by distributing malware through unofficial Telegram channels, fake app stores, GitHub repositories, and fake websites mimicking the game.
🎮 Even the genuine game, only available on Telegram, hasn’t been scrutinized for security, and clone apps on Google Play are reported to scam users.
📱 Android users are targeted by spyware disguised as the game, which can steal notifications, send SMS messages, and hide its actions.

Top 5 takeaways:

🌐 The network uses distinct roles for accounts to maintain operations even when some accounts are banned, ensuring continuous malware distribution.
🥸 The network uses multiple GitHub accounts to star, fork, and subscribe to repositories, making them appear legitimate. This method has evolved from traditional email-based malware distribution.
😈 The Stargazer Goblin group behind this network has earned approximately $100,000 through their operations.
🛡️ Users are advised to be cautious with file downloads from GitHub and to scan password-protected archives using virtual machines or services like VirusTotal.
