T1059.005 Visual Basic
T1204.002 Malicious File
T1566.001 Spearphishing Attachment
The sample is an OOXML document containing VBA macros, specifically an AutoOpen macro that utilizes CreateObject to execute code. ClamAV identifies this as a dropper. The VBA script, though truncated, indicates an attempt to download and execute a second-stage payload, which is a common technique for malware distribution.

-
VBA project inside OOXML medium 3 related findings OOXML_VBADocument contains a VBA project — VBA macros present
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject callMatched line in script
Set oScript = CreateObject(ocwat1 & gbohi2 & iqywsyh9 & wdite & cgyzmycyz & ypyh9 & xgozsajzi & loqtu & ppunus3 & akbahpucq3) -
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled 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.

AutoOpen macro low OLE_VBA_AUTOOPENAutoOpen macroMatched line in script
Sub AutoOpen() -
