 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

The Register link This is a nasty one. Attacking internet-connected Modbus TCP systems on port 152 at the moment. Potentially that's a huge number of targets. Another reason why internet connections on industrial plant should be for read-only monitoring and never control!

I wonder if EtherCAT could be vulnerable...Yikes! Robots and CNC machines flying out of control.  |

Anything with write access that's connected to the internet is vulnerable to something. Essential or safety-related stuff should never be connected to the internet in any way whatsoever. It's not even safe to monitor it remotely unless it's on the end of its own piece of wire. This is a big advantage of local network chips like the nRF24L01, which although it's an RF system and potentially hackable it has no router access and it can use channel hopping to confuse MITM attacks.

Anyone who connects a modbus tcp system to the WWW is plain stupid. Darwin explains why some species have been unsuccesfull in surviving. Humans included.... Volhout P.S. EtherCat needs a bridge (convertor) to get to normal UTP networks. Ethercat as such is incompatible with ethernet. But it uses the same physical interface. All OSI layers above it are different. When you connect the bridge to the WWW then you are fall into the same Darwin category.... Edited 2024-07-24 19:48 by Volhout PicomiteVGA PETSCII ROBOTS |

Yeah, ESP-NOW has me intrigued. I have read reports of <2mS round-trip messaging.  |
