MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The file is a malicious Microsoft Word document containing VBA macros, specifically a Document_Open macro. The ClamAV heuristic also flags it as Doc.Trojan.Thus-10. The document body presents what appears to be a resume, a common lure for social engineering attacks. The presence of a Document_Open macro strongly suggests an intent to execute malicious code upon opening the document, likely to download and execute a secondary payload.
