I received a strange letter in the mail with unreadable and Japanese characters. What is it, a bug or a hack attempt?

Question

Email

Interesting to know what it is:

Message .eml file

Answer 1

Nothing surprising. If you shine your email on the entire Internet, then all sorts of rubbish will fall on it.

Answer 2

Have you tried using google translator?

Answer 3

Check the file on the www.virustotal.com resource, maybe it will give you something.
If there are hyperlinks, move the mouse cursor and see where they lead (links can also be checked on an already indicated resource).
