MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample is a malicious OLE document containing VBA macros. The 'AutoOpen' macro is present and uses 'CreateObject' to execute code, indicating it's designed to run automatically when the document is opened after macros are enabled. The document body explicitly asks the user to activate macros. The presence of an unknown URL suggests a potential download or command-and-control channel.

Heuristics 6

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.
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.
