DET0720 Detection of Obfuscated Files or Information
AN1851 Analytic 1851
Defender correlates a sandboxed app writing high-entropy or encoded artifacts (often in app-private or shared storage), performing decode/decompress/reassembly, then dynamically loading/execing the resulting code (DexClassLoader/JNI dlopen) or spawning a helper process. Sequence: high-entropy file writes → decode/unpack bursts → new .dex/.so/.jar creation in temp/obfuscated paths → dynamic load or shell spawn within a tight window.
AN1852 Analytic 1852
Defender correlates a sandboxed app downloading or receiving opaque/encoded blobs, writing high-entropy content into container/tmp, performing decode/decompress/reassembly, and then executing/loaded as Mach-O or bundle (dlopen) or leveraging JIT/RWX pages to run the decoded payload. Sequence: opaque download or IPC → high-entropy writes/split-file bursts → decode/unarchive → new Mach-O/bundle in tmp → dlopen/posix_spawn or RWX region activity.
