MITRE ATT&CK

T1059.005 Visual Basic for Applications T1204.002 Malicious File

The sample is an Excel spreadsheet containing VBA macros, as indicated by the OLE_VBA_MACROS heuristic. The presence of CreateObject and CallByName calls, along with a lure to enable macros, suggests a malicious intent to execute code. The ClamAV detection further confirms its malicious nature. While no specific payload URL was extracted, the macros themselves are the primary artifact of interest.

ClamAV: Xls.Malware.Exvk-9785252-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Xls.Malware.Exvk-9785252-0
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
CallByName call high OLE_VBA_CALLBYNAME

CallByName call
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Macro/content-enable lure medium SE_ENABLE_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
