For what it's worth, I downloaded this file and scanned it with Windows Defender and it came back clean. I also uploaded it to a (free) 3rd party malware detection site which reported "No security vendors and no sandboxes flagged this file as malicious". So it appears it is just a normal phishing attack and not a malware attack. That being said, since it is so obviously a phish, there is no reason to actually open it which puts you at risk of some zero-day attack.

I'm actually amazed the original post didn't get caught in spam filters.

You are correct, although getting your payload to be executed or even opened could be difficult, since AFAIK none of the apps that can read .docx (et al.) files will blindly read everything inside the ZIP container.
Every anti-malware engine I know of also knows how to detect zip files and scan inside them.
So it's still useful vector in certain ways, but it's not the open door it once was.

Aren't most Word/PDF files just straight up a ZIP file? So you could easily unzip a word file. Upload your malware or whatever you have. Rezip the file and send it to your target or am I not remembering it correctly?

Hi,

This is likely phishing spam and passing around for further information.

Just opening an email without clicking on anything I understand can be
safe.

I would rather ask than be sorry.    Is this also true of pdf files?

If someone can open safely I would like to have a sense who is behind
this one.

Thanks,

Eduard
