MITRE ATT&CK
T1059.003 Windows Command Shell
The sample exhibits a large amount of slack space within its OLE structure, which is often used to hide malicious content. Furthermore, heuristics indicate suspicious access to the PEB and a direct invocation of cmd.exe, suggesting an attempt to run a command-line payload. No document body text was available for further analysis.
Heuristics 3
-
PEB access via FS segment (x86) high SC_PEB_ACCESSPEB access via FS segment (x86)
-
Suspicious cmd.exe invocation with execution flag high SC_STR_CMDSuspicious cmd.exe invocation with execution flag
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 173,834 bytes but its declared streams total only 94,801 bytes — 79,033 bytes (45%) 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).
