T1204 Malicious File
T1204.002 Malicious File: User Execution: Malicious Attachment
The file is a Microsoft Word document exhibiting a large amount of slack space, a common indicator of packed or obfuscated content. The heuristic 'SC_PEB_ACCESS' suggests the document attempts to access process information, likely to facilitate exploitation. While no specific exploit or payload is directly identified, the combination of these factors strongly indicates an attempt to leverage a vulnerability for remote 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 62,172 bytes but its declared streams total only 16,486 bytes — 45,686 bytes (73%) 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).
