Explanation of the Current Alert Level of GUARDED

The alert level is the overall current threat level.

On November 23, the Cyber Threat Alert Level was evaluated and is remaining at Blue (Guarded) due to open source reports of sophisticated threat actors compromising networks to deploy malware. On November 16, the Cybersecurity and Infrastructure Security Agency (CISA) published a joint Cybersecurity Advisory (CSA) regarding Iranian Government-sponsored APT Actors having compromised a Federal Civilian Executive Branch (FCEB) entity using a Log4shell vulnerability in an unpatched VMWare Horizon server and deployed XMRig coinminer and keylogger malware. 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.
