MITRE ATT&CK
T1059.001 PowerShell
The sample is a malicious OLE document with a large amount of slack space, indicating potential obfuscation or embedded malicious content. Heuristics indicate PEB access, often used by malware to evade detection. The document body contains VBA code that attempts to write to the registry key HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\h, likely to disable security features or establish persistence. The VBA code also appears to contain functions for file operations and process execution, suggesting it's a downloader or initial execution stage.
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 135,216 bytes but its declared streams total only 16,486 bytes — 118,730 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).
