Description

Adversaries may attempt to upload a program from a PLC to gather information about an industrial process. Uploading a program may allow them to acquire and study the underlying logic. Methods of program upload include vendor software, which enables the user to upload and read a program running on a PLC. This software can be used to upload the target program to a workstation, jump box, or an interfacing device.


Procedure Examples

  • Stuxnet replaces the DLL responsible for reading projects from a PLC to the step7 software. This allows Stuxnet the ability to upload a program from the PLC.1
