For the past two weeks or so, I haven't found any malspam using password-protected zip archives with Word documents having macros for Ursnif.  However, on Tuesday 2020-02-11, malspam from this campaign has resumed.  This time, it used Italian language Word documents with macros for Ursnif.  @reecdeep started a Twitter thread with some of the details (link).

Shown above:  An infection chain from this campaign seen on Tuesday 2020-02-11.

Today's diary has a quick review of an infection from this campaign from Tuesday 2020-02-11.

Finding the associated Word documents

I searched VirusTotal Enterprise using the following criteria and found at least 66 password-protected zip archives containing the file info_02_11.doc from Tuesday 2020-02-11:

info_02_10.doc tag:zip fs:2020-02-10+

None of the associated emails had been submitted to VirusTotal, so I had to guess at the password.  Several of these zip archives used 111 as the password.  One of them used 222 as the password.  The example I used for an infection had 333 as the password.

Shown above:  Searching VirusTotal Enterprise for zip archives containing info_02_11.doc.

Shown above:  After a couple of guesses, I found the proper password for one of the zip archives from my VirusTotal search.
