MITRE ATT&CK

T1059.001 PowerShell T1059.003 Windows Command Shell T1059.005 Visual Basic T1204.002 Malicious File

The critical ClamAV detection and high-severity heuristics for VBA macros, Workbook_Open, CreateObject, and Wscript.Shell indicate a malicious downloader. The Workbook_Open macro uses Wscript.Shell to execute a batch file located at 'c:\programdata\jledshf.bat', which in turn appears to download and execute a DLL from a hardcoded URL. The reconstructed URL is 'http://moneypuote.ja.deals/assets/jcCwxbvuSREPS7VhWxj/, http://vestaseguridada.com.ar/wp-content/7JD9ugfnwG/, http://mail.rededucacionvirtual.com/wp-includes/BqJi1K/, http://veluxcucumberapi.orbitawaves.it/assets/W9KfK84'.

CreateObject call
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
