3.4 RESEARCHER

Dan Regalado from Zingbox reported this vulnerability to NCCIC.

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:

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.
