T1203 Exploitation for Client Execution
The sample is a malicious OLE document exhibiting a large amount of slack space, indicative of potential obfuscation or embedded malicious content. Heuristics indicate PEB access, suggesting attempts to evade detection or manipulate process information. The document body contains VBA-like constructs that appear to attempt to write to the registry key HKCU\Software\Microsoft\Office\11.0\Word\Resiliency\DisabledItems\DisabledItems, likely to establish persistence or disable security features, and potentially execute further code.
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 79,360 bytes but its declared streams total only 16,486 bytes — 62,874 bytes (79%) 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).
