MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a Microsoft Office document containing a VBA macro that is automatically executed when the document is opened (Document_Open macro). The macro utilizes CreateObject, a common technique for executing malicious code. ClamAV detection further confirms its malicious nature, identifying it as Doc.Malware.Emotet-9778566-0. The VBA macro is obfuscated but its presence and execution trigger indicate it's designed to download and execute a secondary payload.

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.

Document contains VBA macro code
Embedded URL info EMBEDDED_URL

One 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.
