Remarks

This packet is received after successfully logging onto Battle.net and usually after receiving the first initial chat events. If the client does not respond to this packet, the client gets dropped two minutes later (give or take about 10 seconds).

The packet is encrypted via standard RC4 hashing, using one key for outbound data and another for inbound. Its purpose is to download and execute Warden modules. Full information on how to handle this packet may be found at the Rudimentary Warden information topic.

0x00 - Warden Module (QWORD) Name of current module (MD5 Hash) a quadword?? Wow, i never knew md5 hashes could be 8 bytes.

should be: (DWORD[4]) Name of current module (DWORD[4]) Decryption seed
