4. MITIGATIONS
Vecna has released a recommended update to mitigate the
vulnerabilities. Vecna recommends the following update process:
By default, VGo has automatic updates enabled so all updates are
performed automatically when Internet access is available. If the VGo
is powered off or in use, a message will appear on the screen asking
if it can be updated when the VGo is next used.
If a VGo unit has automatic updates turned off, the update will not
be downloaded (however, a notice about the update will be displayed
on the VGo's screen). Vecna recommends that automatic updates be
turned on. Select "settings" from the main menu then "advanced
settings" then "automatic updates."
NCCIC 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.
NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
NCCIC 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 ICS-CERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies, that is available for download from the ICS-CERT website.
Organizations observing any suspected malicious activity should follow
their established internal procedures and report their findings to NCCIC
for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities.
