Arrival Details
This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.
NOTES:
This malware arrives in the system as an AutoLISP script bundled with a drawing file (DWG).
It searches for the file base.dcl and acad.lsp in the AutoCAD search path to locate AutoCAD's current working folder.
It drops a copy of itself in AutoCAD's current working folder as acad.LSP. Once a new drawing file is opened, the dropped copy is automatically loaded and executed.
