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

The sample contains VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The macro constructs the URL "http://frolol0.ru/" and then attempts to open a password-protected document named "help.doc" with the password "donttouchme". This indicates a likely attempt to lure the user into interacting with malicious content or to exfiltrate credentials.
