MITRE ATT&CK

T1059.005 Visual Basic T1059.003 Windows Command Shell T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature 'Xls.Downloader.EmotetRed02221-9938910-0', strongly suggesting the Emotet family. The presence of a Workbook_Open macro and CreateObject calls indicates that the VBA code is designed to execute automatically upon opening the document. The script attempts to download and execute a second-stage payload from multiple URLs, including reconstructed URLs like 'http://harperhouseprodcuts.com/Merch2/ARSf1LICoauH1rDi/A' and 'http://holubividoe.com/eln-images/zqqzg0YXPibF/A', and saves them as 'c:\programdata\yhjlswle.vbs' and 'c:\programdata\ughldskbhn.bat'.
