MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample is identified as malicious by ClamAV with a specific detection name (Ppt.Exploit.Apptom-10029459-0). High-severity heuristics indicate the presence of VBA macros, specifically an AutoOpen macro and CreateObject calls, which are commonly used to execute malicious code. References to VirtualProtect, LoadLibrary, and GetProcAddress APIs suggest dynamic code execution or unpacking. The extracted artifact 'macros.bas' is a VBA macro, likely responsible for the malicious behavior. The document body contains garbled text, offering no clear lure.
