T1027 Obfuscated Files or Information
The sample exhibits critical heuristic firings for XOR-encoded strings and high OLE slack anomalies, indicating a deliberate attempt to obfuscate its contents. The XOR key 0x92 was identified. The document body is heavily corrupted and does not provide further context on the intended lure or payload.
Heuristics 2
-
XOR-encoded strings (key 0x92) critical SC_XOR_ENCODEDFound 2 Windows library/API name(s) XOR-encoded with single-byte key 0x92: 'advapi32.dll', 'shell32.dll'
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 58,944 bytes but its declared streams total only 23,704 bytes — 35,240 bytes (60%) 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).
