US, UK, and Australia Warning About APT Activity

The advanced persistent threat (APT) group is exploiting vulnerabilities in Microsoft Exchange ProxyShell and Fortinet.
Editor's Note
Review the mitigations in the bulletin irrespective of whether you see yourself as a target. Make sure that you’re keeping systems patched and updated. Take another look at allow/deny lists, particularly on servers which are purpose built to block the execution of unknown software. Make sure that you are always using MFA on privileged accounts and on any remotely accessible services.
