MITIGATIONS\n\nLCDS recommends users update to Version 4.1.0.4150 which can be found at the following location:\n\n[https://laquisscada.com](<https://laquisscada.com/>)\n\nNCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:\n\n * Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.\n * Locate control system networks and remote devices behind firewalls, and isolate them from the business network.\n * 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.\n\nNCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. \n \nNCCIC 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.\n\nAdditional mitigation guidance and recommended practices are publicly available on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. \n \nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.\n\nNCCIC also recommends that users take the following measures to protect themselves from social engineering attacks: \n\n * Do not click web links or open unsolicited attachments in email messages. \n * Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. \n * Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.\n\nNo known public exploits specifically target these vulnerabilities.\n\n## \nContact Information\n\nFor any questions related to this report, please contact the CISA at: \n \nEmail: [CISAservicedesk@cisa.dhs.gov](<mailto:cisaservicedesk@cisa.dhs.gov>) \nToll Free: 1-888-282-0870\n\nFor industrial control systems cybersecurity information: https://us-cert.cisa.gov/ics \nor incident reporting: https://us-cert.cisa.gov/report\n\nCISA continuously strives to improve its products and services.
