MITRE ATT&CK

T1059.005 Visual Basic T1059 Command and Scripting Interpreter T1204.002 Malicious File

The sample contains VBA macros, including an AutoOpen function, which is a common technique for executing malicious code upon opening a document. The script attempts to use LoadLibraryA and CreateObject, indicating it's designed to execute further stages or download additional payloads. The presence of these elements strongly suggests a macro-based malware delivery mechanism.

Heuristics 6

Reference to LoadLibrary API high SC_STR_LOADLIBRARY

Reference to LoadLibrary API
AutoOpen macro high OLE_VBA_AUTOOPEN

AutoOpen 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.
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.
