MITRE ATT&CK
T1059.001 PowerShell
The sample is a malicious Microsoft Word document that exhibits a large slack space anomaly, suggesting hidden or malicious content. The PEB access heuristic indicates potential anti-analysis or code injection techniques. The document body contains obfuscated strings that reconstruct registry paths related to disabled Word items, likely to bypass security controls and ensure execution. The reconstructed paths are HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\3 and HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\1.doc.
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 92,160 bytes but its declared streams total only 16,486 bytes — 75,674 bytes (82%) 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).
