SMB session using srvsvc NetShareEnumAll followed by repeated connection and directory listing of the DATA share.
FTP session where an empty control-channel command is observed in conjunction with non-printable binary data on the control channel.

FTP session where the client issues AUTH TLS to upgrade the connection to Transport Layer Security. This reflects protocol-level encryption negotiation prior to further interaction.
