MITIGATIONS\n\nEaton ceased manufacturing the HMiVU on December 31, 2018, and marked the HMiVU software as end of life. As a result, Eaton no longer provides technical support, security fixes, or other fixes for the HMiVU software. To better serve users and provide ongoing replacement solutions, HMiVU was replaced with the XV100 and XV300 lines of operator interface products. It is strongly recommended HMiVU users contact Eaton for technical support and migration assistance to the XV solution.\n\n**NOTE:** Eaton has discontinued the HMiVU product and has asked users to upgrade.\n\nFor assistance with transitioning to XV, please work directly with the following contacts:\n\n * An Eaton sales contact\n * Eaton\u2019s Technical Resource Center at 1-877-ETN-CARE (386-2273), Option 2, then Option 5\n\nInformation regarding the XV Product offering can be found via the following:\n\n * [www.eaton.com/OI](<https://www.eaton.com/OI>)\n * Eaton Catalog\u2014Volume 7, Tab 05\n\nCISA recommends users take the following measures to protect themselves from social engineering attacks:\n\n * Do not open untrusted files with industrial control systems devices.\n * Do not click web links or open unsolicited attachments in email messages. \n * Refer to [Recognizing and Avoiding Email Scams](<https://www.us-cert.gov/sites/default/files/publications/emailscams_0905.pdf>) for more information on avoiding email scams. \n * Refer to [Avoiding Social Engineering and Phishing Attacks](<https://www.us-cert.gov/ncas/tips/ST04-014>) for more information on social engineering attacks.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. \n \nCISA also provides a section for [control systems security recommended practices](<https://www.us-cert.gov/ics/recommended-practices>) on the ICS webpage on [us-cert.gov](<https://www.us-cert.gov/ics>). Several recommended practices are available for reading and download, including [Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies](<https://www.us-cert.gov/sites/default/files/recommended_practices/NCCIC_ICS-CERT_Defense_in_Depth_2016_S508C.pdf>).\n\nAdditional mitigation guidance and recommended practices are publicly available on the [ICS webpage on us-cert.gov](<https://www.us-cert.gov/ics>) in the Technical Information Paper, [ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies](<https://www.us-cert.gov/ics/tips/ICS-TIP-12-146-01B>). \n \nOrganizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.\n\nNo known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.\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.
