MITRE ATT&CK

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

The sample is a Microsoft Word document containing VBA macros. High-severity heuristics indicate the presence of CreateObject and CallByName calls, commonly used for malicious purposes. The macros appear to be obfuscated, but the intent is to download and execute a second-stage payload. The embedded URL is benign, but the macro's functionality suggests a downloader or droppper.

Heuristics 4

CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
CallByName call high OLE_VBA_CALLBYNAME

CallByName call
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.
