MITRE ATT&CK

T1059.005 Visual Basic for Applications T1204.002 Malicious File

The file is an OLE document containing VBA macros, specifically a Document_Open macro, which is a common technique for initiating malicious actions upon opening. The document body presents a plausible lure of an internship evaluation form, designed to trick the user into enabling macros. The presence of VBA macros and the Document_Open heuristic strongly suggest that the macro is intended to download and execute a second-stage payload. The ClamAV detection as 'Doc.Trojan.Thus-5' further confirms its malicious nature.
