T1203 Exploitation for Client Execution
The sample is a malicious OLE document exhibiting a large slack space anomaly and a detected NOP sled, indicative of shellcode execution. The document body is heavily corrupted, preventing analysis of its specific lure. The presence of these indicators strongly suggests an exploit is embedded within the document, designed to execute arbitrary code upon opening.
Heuristics 2
-
NOP sled detected high SC_NOP_SLEDFound 20+ consecutive 0x90 bytes
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 116,080 bytes but its declared streams total only 16,486 bytes — 99,594 bytes (86%) 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).
