MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.005 Visual Basic
The sample is a malicious OOXML document containing an embedded OLE object that carries a VBA macro. This macro is configured to download a payload from the URL https://www.mediafire.com/file/frjrn9astpfr2ua/1.htm/file. The presence of the embedded macro and the external download URL strongly indicate a spearphishing attachment attack pattern.
Heuristics 3
-
Embedded Office object carries macros critical OFFICE_EMBEDDED_MACRO_OBJECTThis document embeds a second Office file that itself contains a VBA macro project or an Excel 4.0 (XLM) macro sheet. Hiding a macro-bearing workbook or document inside another document — frequently under an obfuscated, non-standard part name — is a macro-smuggling technique that defeats scanners which only inspect the outer document's macro storage. No benign authoring workflow stages a hidden macro project this way.
