NOTES:
This trojan arrives on the system as an AutoLISP script bundled with a drawing (.DWG) file. Once the drawing file is opened, AutoCAD then loads and executes this malware.
It first searches for the file BASE.DCL and looks for ACADDOC.LSP in the same folder where BASE.DCL is located. It also searches for the file ACADDOC.LSP from where the current drawing file is saved. If found, it copies the content of the file to the folder where BASE.DCL is located.
