The warning comes roughly one week after the United States revealed that the same adversary targeted Democratic voters in multiple states with emails seeking to intimidate them into voting for President Donald Trump.
In the previous alert, CISA and the FBI noted that the Iranian hackers targeted known vulnerabilities in virtual private network (VPN) products and content management systems (CMSs), including CVE-2020-5902 (code execution in F5 BIG-IP) and CVE-2017-9248 (XSS in Telerik UI).
