What to do
Solution: Omron recommends updating to the latest version: Omron CX-Programmer: Update to v9.78 Should assistance be needed for the update process, users should contact Omron. Omron provides additional mitigations to reduce the risk: Use antivirus protection by protecting any PC with access to the control system against malware and ensure installation and maintenance of up-to-date commercial grade antivirus software protection. Use strong passwords and change them frequently. Install physical controls, allowing only authorized personnel access to control systems and equipment. Perform virus scans to ensure safety of any USB drives or similar devices before connecting to systems and devices. Enforce multifactor authentication on all devices with remote access to control systems and equipment whenever possible. Perform validation processing, such as backup and range checks, to cope with unintentional modification of input/output data to control systems and devices. Perform periodic data backup and maintenance to prepare for data loss.
