MITRE ATT&CK
T1059.001 PowerShell
The sample is a malicious OLE document exhibiting a large slack space anomaly, indicative of potential obfuscation or embedded malicious content. The document body contains obfuscated strings that, when reconstructed, reveal a registry path for disabling Office add-ins: HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\DisabledItems. This suggests an attempt to bypass security measures or maintain persistence. The PEB access heuristic further supports the malicious nature of the file, likely related to process manipulation or evasion.
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 91,648 bytes but its declared streams total only 16,486 bytes — 75,162 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).
