MITRE ATT&CK

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

The sample is a malicious OLE document containing VBA macros. The 'Document_Open' macro is present and uses 'CreateObject' to likely execute Windows Script Host, indicating an attempt to download and run a second-stage payload. No document body text was available for further analysis of the lure, but the macro execution is a strong indicator of malicious intent.

Heuristics 7

Reference to Windows Script Host high SC_STR_WSCRIPT

Reference to Windows Script Host
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open 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 — context-specific rules above attribute URLs they actually evaluated; this rule lists URLs that were present in the bytes but were not otherwise tied to a specific finding.

URL http://schemas.openxmlformats.org/drawingml/2006/main

Extracted artifacts 1

Files carved from inside the sample during analysis.
