T1203 Exploitation for Client Execution
The sample is a Microsoft Word document exhibiting a critical heuristic for XOR-encoded strings and a high heuristic for an anomalous OLE structure, indicating potential obfuscation and malicious intent. The presence of an embedded URL, though marked as benign, suggests an attempt to interact with external resources. The document body is heavily corrupted, but the presence of '2.doc' and references to 'MS07-014' hint at a potential exploit targeting a Microsoft Office vulnerability.
Heuristics 3
-
XOR-encoded strings (key 0x95) critical SC_XOR_ENCODEDFound 8 Windows library/API name(s) XOR-encoded with single-byte key 0x95: 'GetProcAddress', 'VirtualAlloc', 'VirtualAlloc', 'VirtualAllocEx', 'VirtualProtect', 'VirtualProtect', 'VirtualProtectEx', 'CreateProcessA'
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 202,240 bytes but its declared streams total only 16,486 bytes — 185,754 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).
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://www.seoul.intercontinental.com/intro.htm
