North Korea-linked APT group ScarCruft has been using a new Android spyware called KoSpy to target Korean and English-speaking users.
KoSpy has been observed masquerading as utility apps like Phone Manager and File Manager, and has been distributed through the Google Play Store and Firebase Firestore.
The spyware collects SMS, calls, location, files, audio, and screenshots through plugins, and communicates with its C2 servers for further exploitation.
Researchers have found connections between KoSpy, APT37, and APT43, suggesting broader cyber-espionage operations targeting Korean users.
