Rockwell Automation recommends, where feasible, the precautions and risk
mitigation strategies to this type of attack, like those listed below.
Follow industry best-practices to harden PCs and servers, including
antivirus/anti-malware and application whitelisting solutions. These
recommendations are published in Knowledgebase Article KB546987, which is
available at the following location:
https://rockwellautomation.custhelp.com/app/answers/detail/a_id/546987 (link
is external)
Use trusted software, software patches, antivirus/anti-malware programs,
and interact only with trusted web sites and attachments.
Employ training and awareness programs to educate users on the warning
signs of a phishing or social engineering attack.
NCCIC/ICS-CERT recommends that 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.
ICS-CERT reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended
practices on the ICS-CERT web page. 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 in the ICSCERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies, that is available for download from the ICS-CERT web site.
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to ICS-CERT for
tracking and correlation against other incidents.
In addition, ICS-CERT recommends that users take the following measures to
protect themselves from social engineering attacks:
Do not click web links or open unsolicited attachments in email messages.
Refer to Recognizing and Avoiding Email Scams for more information on
avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacks for more
information on social engineering attacks.
No known public exploits specifically target this vulnerability. This
vulnerability is not remotely exploitable.
