The presence of VBA macros and a high-severity heuristic firing for 'SC_STR_CERTUTIL' indicates the sample attempts to use the certutil utility. This is commonly used to download and decode malicious payloads. The 'OLE_VBA_CREATEOBJ' heuristic further suggests dynamic execution capabilities within the macro. While no specific URLs were extracted, the use of certutil points to a downloader or dropper functionality.
Heuristics 5
-
Reference to certutil (download/decode) high SC_STR_CERTUTILReference to certutil (download/decode)
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject call
-
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGEOne 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_MACROSDocument contains VBA macro code
-
Embedded URL info EMBEDDED_URLOne 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.URL http://schemas.openxmlformats.org/drawingml/2006/main
