T1204.002 Malicious File
The sample is a malicious OLE document exhibiting a large slack space anomaly, indicative of embedded malicious content. Heuristics indicate PEB access, suggesting an attempt to bypass security mechanisms. The embedded VBA code, when reconstructed, reveals attempts to write to the registry key HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\3 and potentially execute a file named '1.doc', likely to establish persistence or load 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 139,504 bytes but its declared streams total only 16,486 bytes — 123,018 bytes (88%) 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).
