Cybersafe Updated Microsoft 365 Hardening Guide Recommendation

Cybersafe is aware of an ongoing spear-phishing campaign using RDP files as email attachments. In this attack, the threat actor attaches a malicious RDP file to a phishing email that when executed, connects the victim to the threat actor's server, giving the threat actor access to sensitive data on the victim's computer like files, network resources, printers, credentials, etc. As this is a highly uncommon email attachment, Cybersafe recommends blocking such emails via your organizations SPAM gateway.

Cybersafe has updated its Microsoft 365 guide in response to this campaign, please contact your solutions advisor for updated instructions as required.

Recommendations

Please review your environment to ensure the above-mentioned issues are patched in a timely manner.  It is security best practice to regularly update and/or patch software to the latest versions.  The vulnerabilities above highlight the security benefits of limiting deployed software to "vendor-supported versions" only.  This dramatically increases the likelihood that new vulnerabilities have a patch issued for them.  Likewise, Cybersafe strongly encourages maintaining an inventory of current software in your environment, which helps ensure and inform your patch and vulnerability management program.
