MITRE ATT&CK
T1059.001 PowerShell
The sample is a malicious OLE document exhibiting a large slack space anomaly and references to LoadLibrary and GetProcAddress APIs, suggesting shellcode execution. While the document body is nonsensical, the presence of these indicators points towards a downloader or exploit. No scripts were extracted, and the embedded URL is benign, limiting further analysis.
Heuristics 5
-
NOP sled detected high SC_NOP_SLEDFound 20+ consecutive 0x90 bytes
-
Reference to LoadLibrary API high SC_STR_LOADLIBRARYReference to LoadLibrary API
-
Reference to GetProcAddress API high SC_STR_GETPROCADDRESSReference to GetProcAddress API
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 132,347 bytes but its declared streams total only 31,351 bytes — 100,996 bytes (76%) 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).
-
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
