On October 28, 2020, the Cyber Threat Alert Level was evaluated and is being raised to Yellow (Elevated) due to vulnerabilities in Mozilla and Cisco products and for heightened awareness of cyber activity in advance of the upcoming General Election. On October 21, the MS-ISAC released an advisory for a vulnerability in Mozilla Firefox which could allow for arbitrary code execution. On October 23, the MS-ISAC released an updated advisory for multiple vulnerabilities in Cisco Adaptive Security Appliance and Firepower Threat Defense, the most severe of which could allow for denial of service. On October 22, CISA and the FBI released joint advisories calling for heightened awareness regarding Russian and Iranian Advanced Persistent Threat (APT) actors attempting to compromise election-related systems. The advisories detailed vulnerabilities being used by the APT actors, as well as how to prevent and mitigate the effects of these compromise attempts. Organizations and users are advised to update and apply all appropriate vendor security patches to vulnerable systems and to continue to update their antivirus signatures daily. Another line of defense includes user awareness training regarding the threats posed by attachments and hypertext links contained in emails especially from un-trusted sources.
