About Dendroid

One of the earliest commercial Android RATs, sold openly around 2014. Identified by the com.connect.MyService service; the config (panel URL, backup URL, password) lives base64-encoded as const-strings stored into the encodedURL / backupURL / encodedPassword fields of MyService.<init>.

About 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).

Other samples signed with this certificate? That's a lead worth checking - but not proof of a shared operator, since signing keys (and the Android debug certificate in particular) are widely reused. See the certificate page for every sample signed with it.
