T1027 Obfuscated Files or Information
The file exhibits characteristics of a malicious document, including a significant amount of slack space within the OLE structure and the presence of XOR-encoded strings. These techniques are commonly used to hide malicious code or payloads. While no specific exploit or payload is directly identified, the obfuscation methods strongly indicate a malicious intent.
Heuristics 3
-
XOR-encoded strings (key 0x95) critical SC_XOR_ENCODEDFound 2 Windows library/API name(s) XOR-encoded with single-byte key 0x95: 'LoadLibraryA', 'GetProcAddress'
-
NOP sled detected high SC_NOP_SLEDFound 20+ consecutive 0x90 bytes
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 385,630 bytes but its declared streams total only 16,486 bytes — 369,144 bytes (96%) 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).
