Arrival Details

This malware arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

It may be manually installed by a user.

NOTES:

This malware is an AutoCAD LISP script that spreads by copying itself as ACAD.LSP to AutoCAD's working folder.

Using AutoCADs search path, it first reads the file BASE.DCL. It then uses the said file to search for another file named ACAD.LSP in the AutoCad support folder.

It opens Drawing1.dwg upon running AutoCad.
