Android spyware targeting Signal and ToTok users in UAE
🔒 ESET researchers uncovered two previously undocumented Android spyware families—Android/Spy.ProSpy and Android/Spy.ToSpy—distributed via deceptive websites that impersonate Signal, ToTok and even app stores. Both families require manual APK installation from third‑party sites and maintain persistence while exfiltrating contacts, media, documents and chat backups. ToSpy notably seeks .ttkmbackup files and uses AES‑CBC encryption with a hardcoded key; several C&C servers remained active. Google Play Protect already blocks known variants, and ESET shared findings with Google.
