T1204 Malicious File Execution
T1059 Command and Scripting Interpreter
The sample is a malicious OLE document exhibiting a large slack space anomaly, indicative of embedded malicious content. A high-severity heuristic firing for PEB access via FS segment suggests an attempt to bypass security mechanisms or gain low-level system access. While no specific document body content or scripts were clearly extracted, the combination of these indicators points towards an exploit attempting to execute arbitrary code.
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 90,624 bytes but its declared streams total only 16,486 bytes — 74,138 bytes (82%) 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).
