Analyst notes

Premium Panel Fraud. Free Fire game top-up / “follower” panel fraud apps (pkg com.premiumPanel.follower), built with Sketchware. No custom C2 server: a Firebase Realtime Database project is the entire serverless backend. RTDB nodes: Price (product catalog shown in MainActivity), Normal (pending-order queue - each order stores the device id, price, time/date, buyer name and a ‘Tock’ token, status “Pending…..”), DONE (fulfilled orders), and Report (ReportActivity writes the device id via getDeviceId()/android_id plus a free-text complaint). PayActivity collects payment through a live Razorpay checkout key and a UPI QR (generated via quickchart.io), writes the order to Normal, then fires an FCM push to the operator. Promoted via Telegram/YouTube (Follower666FF). Not a RAT/spyware: requests only internet/storage/overlay/FCM, no SMS/contacts/location/accessibility, and performs no device control or bulk exfil. Notable: each APK hardcodes the project’s Firebase Admin SDK service-account PRIVATE KEY in PayActivity (to send FCM), which leaks full administrative control of the operator’s Firebase project. Observed backends: getaway-payment-2026final, september-premium-panel2026. Indicators: firebase://september-premium-panel2026.

features
Free Fire top-up/follower 'panel' app. Firebase RTDB = serverless order backend: nodes Price (catalog), Normal (pending orders: Device id, Price, Time, Date, Stu=Pending, name, Tock token), DONE (fulfilled), Report (device id + user complaint). PayActivity takes payment via live Razorpay checkout + UPI QR (quickchart) then writes the order to Normal and pushes an FCM notification to the operator. ReportActivity harvests device id (getDeviceId/android_id). No SMS/contacts/location/accessibility -> fraud infra, not spyware. CRITICAL: APK hardcodes the Firebase Admin SDK service-account PRIVATE KEY (full RSA) in PayActivity to send FCM — leaks full admin control of the operator's Firebase project.

⚠ Embedded admin credential

A Firebase Admin SDK service-account private key is hardcoded in this APK (used by the app to send FCM). It grants full administrative control of the operator's own Firebase project — a takedown / key-revocation lever. It is shown here exactly as it ships inside the distributed malware.
