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

The sample is a macro-enabled Word document that utilizes a Document_Open macro to initiate malicious activity. The VBA script attempts to download and execute a second-stage payload by constructing the URL "dodro7.ru/" and concatenating it with "http" and "t". The script also attempts to open a document with the password "44", suggesting a multi-stage infection process.
