T1204 Malicious File
T1059 Command and Scripting Interpreter
The sample is a malicious OLE document exhibiting a large slack space anomaly, indicating potential obfuscation or embedded malicious content. A PEB access heuristic firing suggests the document may attempt to interact with the process environment to facilitate exploitation. While no specific script or VBA was extracted, the heuristics and file type strongly suggest an attempt to exploit a vulnerability to download and execute a secondary payload.
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 232,448 bytes but its declared streams total only 16,486 bytes — 215,962 bytes (93%) 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).
