MITRE ATT&CK
T1059.005 Visual Basic
T1059.003 Windows Command Shell
T1204.002 Malicious File
The file contains a Workbook_Open VBA macro that utilizes WScript.Shell to execute commands. This macro is designed to download and execute a second-stage payload from one of the numerous embedded URLs. The presence of an appended payload and the nature of the macro strongly indicate a downloader or droppper functionality.
Heuristics 11
-
WScript.Shell usage critical OLE_VBA_WSCRIPTWScript.Shell usage
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 227,840 bytes but its declared streams total only 111,991 bytes — 115,849 bytes (51%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
-
OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOADOLE compound file contains a large high-entropy region beyond the declared major streams and that region includes shellcode, PE, or loader API markers. This is a payload-carrier signal, not a specific CVE attribution by itself.
-
Workbook_Open macro high OLE_VBA_WBOPENWorkbook_Open macro
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject call
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled 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_TRIAGEOne 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_MACROSDocument contains VBA macro code
-
Environ() call (env variable access) low OLE_VBA_ENVIRONEnviron() call (env variable access)
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
Embedded URL info EMBEDDED_URLOne 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 https://monarchmedical.co.uk/ven�Vt���
