MITRE ATT&CK
T1204.002 Malicious File

The file is identified by ClamAV as Xls.Dropper.Agent-7084038-0, indicating it functions as a dropper. The OLE slack anomaly suggests the presence of hidden or packed data, typical of malware. While no scripts were extracted, the embedded URLs, despite some being benign, point towards a potential download or redirection mechanism. The primary purpose appears to be the delivery of a secondary payload.

Heuristics 3

  • ClamAV: Xls.Dropper.Agent-7084038-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Xls.Dropper.Agent-7084038-0
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 113,726 bytes but its declared streams total only 24,565 bytes — 89,161 bytes (78%) 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_URL
    One 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.
