This phish is for the curious mind, there is no context as to why it is sent as the email body is empty. Subject of the email has no meaning on its own just a vague combination of words. There is no reason for anyone to open the attachment, except if you are curious. When we couple curiosity with ignorance, it can lead to negative results, as would be in this case.
Hence, always look for warning signs in an email before taking any action and, think whether you were expecting such email. Never reply back to the scammers asking for more information as they intentionally give vague or no information. Never open attachments in an email, unless you are sure it is not a phish, as it can lead to malware on your device.
