T1204 Malicious File
T1059 Command and Scripting Interpreter
The file is an OLE document with a significant amount of slack space, indicating potential obfuscation or embedded malicious content. The PEB access heuristic suggests the sample attempts to interact with the process environment, often a precursor to exploitation or payload execution. While no specific script was extracted, the heuristics and file type strongly suggest an attempt to exploit a vulnerability to download and execute a secondary payload. The SHA256 hash is included as a primary IOC.

-
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 94,424 bytes but its declared streams total only 16,486 bytes — 77,938 bytes (83%) 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).
