MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature 'Doc.Dropper.EmotetUpdate1020-9778523-0', strongly suggesting it's an Emotet variant. The presence of a Document_Open VBA macro that uses CreateObject and p-code auto-execution indicates the macro is designed to run code upon opening. This macro likely serves as a dropper, downloading and executing a second-stage payload, a common Emotet tactic.

Heuristics 7

ClamAV: Doc.Dropper.EmotetUpdate1020-9778523-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Dropper.EmotetUpdate1020-9778523-0
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.
Suspicious extracted artifact high 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.
VBA macros detected medium OLE_VBA_MACROS

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.
