MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File: User Execution T1105 Ingress Tool Transfer

The sample contains VBA macros that utilize WScript.Shell to create a second-stage payload. The macro attempts to download a file using Microsoft.XMLHTTP and save it to the user's templates directory, indicating a downloader functionality. The embedded lure 'Enable content above to display Receipt.' further supports the malicious intent.

Heuristics 8

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
WScript.Shell usage critical OLE_VBA_WSCRIPT

WScript.Shell usage
VBA downloads and writes a file to disk critical OLE_VBA_HTTP_DROP_EXEC

VBA reads an HTTP response body and writes it to disk (ADODB.Stream SaveToFile). Combined with the auto-exec/Shell paths this is a download-drop dropper even when the COM ProgIDs are built dynamically to evade keyword scanning.

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
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.
