  • ClamAV: Doc.Exploit.CVE_2012_0158-17 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Exploit.CVE_2012_0158-17
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 546,048 bytes but its declared streams total only 16,640 bytes — 529,408 bytes (97%) 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).
  • OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOAD
    OLE compound file contains a large high-entropy region beyond the declared major streams and that region includes shellcode, PE, or loader API markers. This is a payload-carrier signal, not a specific CVE attribution by itself.
