MITRE ATT&CK
T1059.001 PowerShell
The sample is a malicious PowerPoint file exhibiting characteristics of obfuscated content, including a NOP sled and XOR-encoded strings with a key of 0xCC. The large slack space in the OLE structure further suggests malicious intent. While no specific document body text or scripts were clearly extracted, the heuristics strongly indicate the presence of malicious code designed to evade detection and potentially download a secondary payload.
Heuristics 3
-
XOR-encoded strings (key 0xCC) critical SC_XOR_ENCODEDFound 6 Windows library/API name(s) XOR-encoded with single-byte key 0xCC: 'LoadLibraryA', 'LoadLibraryA', 'GetProcAddress', 'GetProcAddress', 'VirtualAlloc', '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 167,988 bytes but its declared streams total only 18,081 bytes — 149,907 bytes (89%) 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).
