MITRE ATT&CK
T1129 Execution through API execution

The file is identified as malicious by ClamAV with the signature Win.Trojan.Exploit-110. The OLE document exhibits a significant amount of slack space, which is a common characteristic of packed or obfuscated malicious files. The document body consists of jokes, suggesting a social engineering tactic to mask the malicious payload. No scripts were extracted from this sample.

Heuristics 2

  • ClamAV: Win.Trojan.Exploit-110 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Exploit-110
  • OLE document has large unaccounted-for region high OLE_SLACK_ANOMALY
    OLE file is 633,344 bytes but its declared streams total only 32,705 bytes — 600,639 bytes (95%) 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).
