MITRE ATT&CK
T1203 Exploitation for Client Execution
The sample is a malicious OLE document exhibiting a large slack space anomaly and containing embedded EMF objects. It references LoadLibrary and GetProcAddress APIs, indicating an attempt to dynamically load code. The document body contains references to embedded Excel and PowerPoint objects, further supporting the malicious nature.
Heuristics 5
-
Office EPRINT stream contains EMF object high OLE_EPRINT_EMF_OBJECTOLE ObjectPool contains an EPRINT stream with EMF data. This is rare in normal documents and is CVE-2007-3893/MS07-046-family evidence when paired with Office exploit payload anomalies, but the malformed EMF record is not proven by this rule alone.
-
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 125,440 bytes but its declared streams total only 31,351 bytes — 94,089 bytes (75%) 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
