MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1140 Deobfuscate or Obfuscate Malicious Code

The file is identified as malicious by ClamAV with the signature 'Doc.Dropper.EmotetWinMob0920-9636503-0', indicating it's a dropper for the Emotet family. The presence of a Document_Open macro and CreateObject calls strongly suggests that the VBA code is designed to execute automatically when the document is opened. The macro code appears to be obfuscated, likely to hide its true functionality, which is common for Emotet droppers to download and execute further stages.

ClamAV: Doc.Dropper.EmotetWinMob0920-9636503-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Dropper.EmotetWinMob0920-9636503-0
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled 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.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One 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.
