MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature Doc.Downloader.SVCReady-c5c43a913b3eccc9-9953477-0. A critical heuristic indicates it's a downloader, and a medium heuristic confirms a macro-enable lure is present, instructing the user to enable macros to view content. This suggests the document's primary purpose is to download and execute a secondary payload.
