T1204.002 Malicious File
T1027 Obfuscated Files or Information
The sample is a PowerPoint file exhibiting characteristics of malicious intent, including a large slack space anomaly and the presence of a NOP sled. Crucially, XOR-encoded strings were detected, indicating obfuscation techniques are in use. The lack of readable document body text or extracted scripts prevents a more detailed analysis of the specific lure or payload, but the heuristics strongly suggest an embedded exploit.
Heuristics 3
-
XOR-encoded strings (key 0x89) critical SC_XOR_ENCODEDFound 4 Windows library/API name(s) XOR-encoded with single-byte key 0x89: 'LoadLibraryA', 'LoadLibraryW', 'GetProcAddress', 'RegOpenKeyExA'
-
NOP sled detected high SC_NOP_SLEDFound 20+ consecutive 0x90 bytes
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 155,140 bytes but its declared streams total only 18,081 bytes — 137,059 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).
