Weird Spam Emails Consist of Random Numbers and Letters as the Email Subject

Several days ago, I received a weird spam email. The email subject is so weird because the subject consists of random letters and numbers arrangement. Because it was so suspicious, I immediately deleted it.

However, the next day when I woke up, I received the same email in my inbox and there are 10 more emails of the same format except it all came from a different domain names and email address. I deleted all of it again.

But this does stop the spammer from sending more spam. The same type of email came to my inbox on the next day and it keeps coming until today. It's already been five days now and even though I already created a numerous email rules on PopTray, but PopTray cannot detect it as spam because the email subjects is contstantly changing but still in the same random numbers and letters format.

The subject is something like '?xbFhkd=?kdjuh' but longer. I'm not clear about this threat yet. But, it best for us to be careful to prevent something bad from happening. So, I'm posting this here to warn you about this email.

If you received this type of email in your inbox, delete it immediately. I'm going to try a different approach in dealing with this type of spam and if it works, I'll tell you.
