T1204.002 Malicious File
The sample is a malicious OLE document with a significant amount of slack space, indicating potential obfuscation or embedded malicious content. The presence of an x86 GetPC stub suggests the execution of shellcode. While no specific exploit or payload is directly identifiable from the provided heuristics and document body, the overall structure and heuristic firings point towards a classic exploit document designed to execute arbitrary code upon opening.
Heuristics 2
-
x86 GetPC stub (CALL $+5; POP EAX) high SC_GETPC_CALLx86 GetPC stub (CALL $+5; POP EAX)
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 188,929 bytes but its declared streams total only 16,536 bytes — 172,393 bytes (91%) 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).
