I was reading the research I shared with you several times and I got few conclusions
- the reported issues would be very difficult to fix and Siemens would not be able to release a "quick and dirty" patch.
- all of the attacks were conducted through the network.
as a result the only immediate mitigation method would be a proper network visibility/detection and prevention solution exactly like we offer. Our Asset and Anomaly Detection solution would alert about any rouge configuration changes, while our strong prevention techniques would immediately stop it.
