Malware Insights
The presence of a NOP sled and XOR-encoded strings are strong indicators of malicious intent, commonly found in exploit-laden documents. The OLE slack anomaly further suggests obfuscation or padding typical of malware. While no specific VBA or script content was provided, the heuristics point towards a malicious PowerPoint file, likely attempting to execute code or exploit a vulnerability.
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 225,844 bytes but its declared streams total only 18,081 bytes — 207,763 bytes (92%) 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).
