T1203 Exploitation for Client Execution
The sample is a malicious OLE document exhibiting a high degree of slack space, indicative of potential obfuscation or embedded exploit code. The PEB access heuristic further suggests an attempt to manipulate process execution. While no specific document body content or scripts were extracted, these indicators strongly point towards an exploitation attempt to achieve arbitrary code execution.
Heuristics 2
-
PEB access via FS segment (x86) high SC_PEB_ACCESSPEB access via FS segment (x86)
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 75,264 bytes but its declared streams total only 16,486 bytes — 58,778 bytes (78%) 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).
