T1204.002 Malicious File
T1059.001 PowerShell
The sample is a malicious OLE document exhibiting a large slack space anomaly, indicative of embedded malicious content. The PEB access heuristic suggests an attempt to evade detection or manipulate process information. While no explicit script was extracted, the Office facts reveal VBA code that likely attempts to write to the registry key HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\3 and HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\1.doc, potentially to establish persistence or disable security features, and then execute a 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 121,904 bytes but its declared streams total only 16,486 bytes — 105,418 bytes (86%) 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).
