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

The file is identified as malicious by ClamAV with the signature 'Doc.Dropper.Agent-7534412-0'. Static analysis detected the presence of VBA macros, a CreateObject call, and a CallByName call, indicating that the document is designed to execute code. The truncated document body suggests obfuscated JavaScript or VBA, likely intended to download and execute a second-stage payload. The embedded URL was confirmed as benign, so it is not included as an IOC.
