Android App Symoo Exfiltrates SMS Data for Fake Account Creation
Evina researcher Maxime Ingrao uncovered Symoo, a fake Android SMS app with 100,000 downloads. It acts as an SMS relay service for account creation for the likes of Google, Instagram, Microsoft, Telegram, and Facebook. It was observed that Symoo exfiltrates SMS data to a domain in use by another application on Google Play, Virtual Number (not available anymore).
