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

The sample is a malicious Microsoft Word document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The document body presents itself as a job application or profile, using embedded URLs and an email address as lures. The presence of a Document_Open macro strongly suggests the intent to automatically execute malicious code upon opening, likely to download and execute a secondary payload. The ClamAV detection as 'Doc.Trojan.Thus-16' further supports its malicious nature.
