MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with the signature Doc.Trojan.Xaler-1. It contains VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The document body presents itself as a statistical report from the North Kazakhstan Oblast Statistics Department, a common lure to trick users into enabling macros. The presence of VBA macros and the Document_Open trigger strongly suggest the intent is to execute malicious code, likely to download and run a secondary payload.

Heuristics 5

  • ClamAV: Doc.Trojan.Xaler-1 critical CLAMAV_DETECTION
