MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The file is identified as malicious by ClamAV with the signature 'Img.Dropper.PhishingLure-6443153-0'. Static analysis revealed a VBA macro with an AutoOpen function, indicating it will execute automatically when the document is opened. The macro contains obfuscated code and calls 'Application.Run', suggesting it attempts to execute further malicious actions, likely downloading a payload. The large slack space in the OLE structure is also anomalous.

ClamAV: Img.Dropper.PhishingLure-6443153-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Img.Dropper.PhishingLure-6443153-0
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 76,053 bytes but its declared streams total only 24,563 bytes — 51,490 bytes (68%) 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).
