Defender correlates an app's opaque media ingress (download/IPC) with high-entropy or anomalous edits to image/audio/video files in app-writable storage (e.g., bursts of bitmap/codec operations, EXIF/IPTC/XMP mutation, suspicious container growth), followed by decoding/extraction behavior (new non-media artifact derived from the edited media) and optional exfiltration/sharing of the stego media. Focus is on: (1) opaque media arrival → (2) rapid metadata or pixel-domain mutations with atypical size/entropy deltas → (3a) decoded payload creation or dynamic load from decoded path, and/or (3b) upload/share of the modified media within a tight window.
