MITRE ATT&CK
T1059.005 Visual Basic for Applications T1204.002 Malicious File

The sample contains a VBA macro that executes upon opening the document. This macro constructs a URL, 'http://frolol0.ru/', and then attempts to open a password-protected document named 'help.doc' from that URL. The password 'donttouchme' is also specified. The macro's intent is to download and open a malicious second-stage document. The benign URLs extracted are part of the document's schema and not malicious.
