SyamRAT (provisional)

Commodity Indonesian Android RAT distributed under utility/“booster” lures (e.g. package com.pt.sejahtera, label “pelancar hp” — Indonesian for “phone booster”). The build ships a plaintext assets/config.json naming the operator backend, and abuses AccessibilityService + MediaProjection for remote control, overlay injection and live screen capture. A bundled native module (libnuker.so / assets/nuker, an ELF) provides the screen-stream/VNC component. Live control runs over Socket.IO to the base_url in the config.

How the C2 is recovered: config.json is cleartext, so the decoder reads base_url directly (binary-verified). The webview_url (commonly https://www.google.com) and logo_url (image CDNs such as catbox.moe) are victim-facing decoys and are not recorded as C2. The operator username, session_id and per-build uid (from assets/uid.json) are captured as attribution. Family label is provisional — this is a builder kit, not a single actor.
