T1204.002 Malicious File
T1566.001 Spearphishing Attachment
The file is an Excel spreadsheet containing a Workbook_Open VBA macro. This macro utilizes the Shell() function, indicating an intent to execute arbitrary commands. The macro also contains obfuscated string concatenations that likely form a URL or command to download and execute a secondary payload. The presence of the Workbook_Open event and Shell() call strongly suggests a malicious document designed to deliver further malware.
Heuristics 6
-
Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
Workbook_Open macro high OLE_VBA_WBOPENWorkbook_Open macro
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject call
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Environ() call (env variable access) low OLE_VBA_ENVIRONEnviron() call (env variable access)
-
Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATEDThe document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
