MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File T1059.001 PowerShell

The critical ClamAV detection and high-severity heuristics for Workbook_Open macros and CreateObject calls indicate malicious intent. The embedded VBA script, specifically the `FHsdrghkldsSeErhoihsw` subroutine, attempts to download and execute a second-stage payload. It reconstructs the following URLs for this purpose: "http://sumedahonline.com/wp-content/HyzNXJ30XQVBSRH/", "http://divachintextiles.com/wp-incudades/WHwWRKs8KvzNFm6/", "http://hotelanmalabol.com/1520/bUdhEpdf/", and "http://shwenantawin.com/copma/XTnZii02vfgV". Additionally, it writes a batch file to `c:\programdata\jledshf.bat` and a VBScript to `c:\programdata\tghklsd.vbs`.
