MITRE ATT&CK
T1059.005 Visual Basic
T1059.003 Windows Command Shell
The file is identified as malicious by ClamAV with multiple critical heuristic firings indicating the presence of VBA macros and the execution of shell commands. The extracted artifact 'macros.bas' is a VBA macro. The shell command execution suggests the macro is designed to download and execute a secondary payload, a common technique for malware delivery. The document body content appears to be unrelated academic material, suggesting it's a lure.
