Beijing-based Sunway ForceControl Technology Co. provides SCADA/HMI applications for industries including petroleum, petrochemical, defense, railways, coal, energy, pharmaceutical, telecommunications, water, and manufacturing. The company’s products see use mainly in China, but they are also in Europe, the Americas, Asia, and Africa.

ICS-CERT recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Users should:

  • Minimize network exposure for all control system devices. Control system devices should not directly face the Internet.
  • Locate control system networks and devices behind firewalls, and isolate them from the business network.
  • If remote access is required, employ secure methods such as Virtual Private Networks (VPNs), recognizing that VPN is only as secure as the connected devices.
