T1059.001 PowerShell
T1059.003 Windows Command Shell
T1566.001 Spearphishing Attachment
The document contains a heavily obfuscated PowerShell command embedded within the document body. This command is designed to decompress and execute a Base64 encoded payload, likely a second-stage downloader. The presence of cmd.exe and PowerShell execution heuristics strongly suggests an attempt to download and run additional malicious content, characteristic of a macro-based downloader.
Heuristics 5
-
Suspicious cmd.exe invocation with execution flag high SC_STR_CMDSuspicious cmd.exe invocation with execution flag
-
Reference to PowerShell high SC_STR_POWERSHELLReference to PowerShell
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 77,442 bytes but its declared streams total only 0 bytes — 77,442 bytes (100%) 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).
-
LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMANDExtracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
-
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)
