4. MITIGATIONS

ABB reports PGIM will transition to a limited support phase in January, 2020, and Plant Connect is already obsolete.

Users are advised to upgrade to Symphony Plus Historian, which is not affected by this vulnerability. Symphony Plus Historian is the successor to the PGIM and Plant Connect products and features improved cybersecurity.

ABB further recommends users of PGIM not use the same credentials for Windows login as used to log into the PGIM and Plant Connect applications. Additionally, end users who cannot immediately upgrade should consider protecting network communication by use of IPSec or other means. Users should contact ABB for additional support details.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:

• Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
• Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
• When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.gov in the Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
