MITRE ATT&CK

T1059.005 Visual Basic T1547.001 Registry Run Keys / Startup Folder

The sample is a malicious Word document containing VBA macros, specifically a Document_Open macro. This macro attempts to copy itself to the Normal template and any other open documents, indicating an attempt to establish persistence. The script also includes logic that appears to be date-dependent, suggesting it may execute further malicious actions on specific dates, such as December 13th. The ClamAV detection 'Doc.Trojan.Thus-8' further confirms its malicious nature.
