All of you is probably familiar with Stuxnet and what it did.
If you need a refresh, here is a presentation from Stanford:
https://www.youtube.com/watch?v=DDH4m6M-ZIU
What i would like to know/discuss is how the PLC-code would have looked like and how it got injected.
Did it tamper with existing FC´s/FB´s? Or added new ones?
Some of the functions (like the emergency stops that got disabled) might have been written on Failsafe-CPU. Changing safetyprograms changes checksums, needs passwords etc..
Does anyone of you know more about this?
