About RatHat

AI-powered Android credential stealer / RAT (Zimperium, Sep 2026) posing as reward or finance apps (`Tether`, `ReelShort` lures). It serialises the live Accessibility tree to XML and queries Google **Gemini** to resolve on-screen targets and drive synthetic clicks - letting it read and operate banking and wallet apps on the victim's behalf without a human operator. Heavily hardened against analysis: a ~61 MB `AndroidManifest.xml` padded with `0x9999`-byte junk chunks, DEX poisoning (deliberately malformed bytecode that breaks naïve disassemblers), `StringFog`/`StringCrypto` string encryption and ZIP tampering. Configuration lives in a **ZM26 container** under `assets/` - RatHat's own encrypted-blob format: a 4-byte `ZM26` magic, an 8-byte salt, then the payload XOR'd with a repeating 24-byte key (the per-sample `xor_key` from `assets/zm26_meta.json`, concatenated with that salt). The C2 is the `serverUrl` field of `server_config.json` - recoverable in plaintext in some builds, `ZM26`-encrypted in others. The primary FRP tunnel C2 is not a static indicator: it is fetched at runtime by the bundled Go agent `liblocal-service.so`, while `libmedia_codec.so` masquerades as the `frpc` tunnel client.
