For users who are using a product that has not released a fixed version or who
cannot immediately update the product, Mitsubishi Electric recommends taking
the following mitigation measures to minimize risk:

  o Install the fixed version GX Works2, GX Works3, or MELSOFT Navigator on the
    PC on which the product is installed. This is because these three products
    provide comprehensive countermeasures that give the same countermeasure
    effect to other products installed in the same folder (e.g. C:\Program
    files\MELSOFT).
  o Operate the products under an account that does not have administrator's
    privileges.
  o Install an antivirus software in computers using the products.
  o Restrict network exposure for all control system devices or systems to the
    minimum necessary and ensure they are not accessible from untrusted
    networks and hosts.
  o Locate control system networks and remote devices behind firewalls and
    isolate them from the network.
  o Use virtual private network (VPN) when remote access is required.

Additional information about the vulnerability or the Mitsubishi Electric
compensating control is available by contacting a Mitsubishi Electric
representative .

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.

CISA also recommends users take the following measures to protect themselves
from social engineering attacks:

  o Do not click web links or open unsolicited attachments in email messages.
