The Cybersecurity and Infrastructure Security Agency (CISA) has published an alert to provide information on attacks delivering the KONNI remote access Trojan (RAT).

In an alert published on Friday, CISA warns of emails delivering Microsoft Word documents that contain malicious Visual Basic Application (VBA) macro code designed to fetch and install the KONNI malware.
The macro code, CISA explains, was designed to change the font color to trick the victim into enabling content, check whether the system architecture is 32-bit or 64-bit, and construct and run a command line to download additional files. Certificate database tool CertUtil is employed for the download of remote files. [...]

To stay protected from this threat, users and administrators should ensure their systems are up to date, should have an updated anti-virus solution running on their devices, should avoid opening email attachments from unknown sources, and should implement policies related to user permissions, passwords, allowed services, software downloads, and the monitoring of user behavior.
