Analyst notes

Metasploit. Android payloads generated by Metasploit / msfvenom (meterpreter and command stages), running under the package com.metasploit.stage. The payload dials back to LHOST:LPORT, which is the C2. Two config formats appear in the wild. In the older/plain format the transport URL (tcp://, ssl:// or https://LHOST:LPORT) is a const-string in the DEX. In the newer format the stage carries a protobuf TransportConfig in the static byte array Payload.a, parsed by an embedded protobuf-lite runtime (com.metasploit.a); that array is XOR-masked with a per-build 4-byte key, and because the buffer is zero-padded the leading bytes leak the key, so XORing the array by key[i mod 4] recovers the protobuf and its transport URL. Many samples are red-team or test builds pointing at LAN, loopback or 0.0.0.0 addresses (recorded verbatim); live ones use public IPs or tunnel fronts such as *.lhr.life (localhost.run) and *.loca.lt (localtunnel). Indicators: https://a01fb7af0461b1.lhr.life:443.

Recovered configuration

cluster_note

Same tunnel host reused across 4 samples (0e374119,a32c17e3,a7f01fc2,ba9df4f7) -> one operator/build run (reserved tunnel).

indicator_note

Ephemeral reverse-tunnel rendezvous on shared SaaS (localhost.run/localtunnel); the full per-session hostname is the beacon target but rotates and the bare apex must never be blocked.
