MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample contains a VBA macro that executes upon opening the document. This macro constructs the URL "http://frolol0.ru/" and then attempts to open a password-protected document named "help.doc" from this domain. The macro's intent is to download and potentially execute a malicious payload disguised as a document. The password "donttouchme" is also embedded within the script.
