Orphaned VBA Projects Inside DWG Files, (Wed, Oct 14th)
Years ago I wrote diary entries about VBA code stored inside AutoCAD drawing files (.dwg). In a nutshell: the VBA code is stored inside an OLE file, that is embedded inside the DWG file. You can do a brute-force search for the embedded OLE file, or you can follow a pointer inside the header of the DWG file. I wrote a small Python script (autocad.py) for this second case. It looks at a 32-bit pointer at position 0x24 inside the DWG file. This points to a 16-byte long header, followed by the…
