    Added a few power meters to the equipment to monitor energy consumption. They communicate with the Intelligent Chart Recorder via Modbus 🫠

  2. It is appalling that PLC devices are connected to the Internet. I get why it happens, a former company I worked for had a vendor install an SCADA + HVAC system, networking provided a standard drop without configuring the specific restricted VLAN. That system was open to the internet with the default password as "password." No one checked the network other than active connectivity and the system was put on the internet.

    For water and power companies it is unbelievably negligent to connect SCADA to the Internet. There should be no reason why we need task force, after task force to solve this entirely self owned problem. This was a problem back in the early 2000s and systems are still placed on the Internet.

    What is a solution? How about a private network between utility companies with encrypted traffic, not connected to the open Internet. If Internet monitoring is required, configure a very secure VPN to a DMZ.

  3. @metacurity "An additional development could prove significant as investigators continue examining the attacks.

    "According to a source familiar with the federal investigation, authorities are examining whether vulnerable #RockwellAutomation #MicroLogix 1400 PLCs served as a common enabling factor in the campaign.

    "Fabela ran a targeted Shodan search on Plymouth’s public IP space and found the city using at least two #Rockwell Automation MicroLogix 1400 controllers.

    "The possibility aligns with both recent federal warnings and a July 30 Rockwell Automation security advisory addressing the MicroLogix 1400 family of controllers. Earlier federal guidance identified Rockwell Automation / #AllenBradley PLCs among the industrial controllers being actively targeted by Iranian-affiliated threat actors before expanding the warning to additional #PLC manufacturers."

  4. Compact control can still deliver complete machine functionality.
