T1059.005 Visual Basic
T1204.002 Malicious File
T1059 Command and Scripting Interpreter
The sample is a malicious Office document containing VBA macros. The 'autoopen' macro and critical heuristics indicate the use of GetObject and CreateObject to launch 'winmgmts' for process creation, a common technique for downloading and executing further stages. ClamAV also identified it as a downloader.
Heuristics 8
-
ClamAV: Doc.Downloader.Powload-6956387-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Doc.Downloader.Powload-6956387-0
-
VBA macros detected medium 4 related findings OLE_VBA_MACROSDocument contains VBA macro code
-
VBA WMI Win32_Process launcher critical OLE_VBA_WMI_PROCESS_CREATEVBA macro builds or references a WMI moniker for Win32_Process and invokes .Create to start a command. This is a high-confidence macro execution chain that often hides the WMI class name through string concatenation or helper functions.
-
Dangerous API name reassembled from split string literals critical OLE_VBA_SPLIT_KEYWORD_OBFUSCATIONVBA concatenates short string literals that reassemble a dangerous API/ProgID/LOLBin name (e.g. Scripting.FileSystemObject, WScript.Shell, powershell, URLDownloadToFile) which appears in no single literal. Splitting an API name across string concatenation is done only to evade keyword scanning.
-
AutoOpen macro high OLE_VBA_AUTOOPENAutoOpen macro
-
GetObject call high OLE_VBA_GETOBJGetObject call
-
Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXECOLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
-
Embedded URL info EMBEDDED_URLOne 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.URL http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
