MITRE ATT&CK

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

The critical ClamAV heuristic and high-severity OLE_VBA_MACROS, OLE_VBA_DOCOPEN, OLE_VBA_CREATEOBJ, and OLE_VBA_PCODE_AUTOEXEC_EXEC firings indicate the presence of a malicious VBA macro designed to execute automatically upon opening the document. The macro likely uses CreateObject to download and execute a second-stage payload, consistent with Emotet downloader behavior.

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.

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.
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.
