Identified - Summary
Microsoft has discovered limited, targeted abuse of a Microsoft Outlook vulnerability that allows for NTLM credential theft. The vulnerability can be exploited by sending a malicious email to a vulnerable version of Outlook, and Microsoft note that the exploitation can occur even before the message is viewed in the Preview Pane; so no user interaction is required.
All supported versions of Microsoft Outlook for Windows are affected. Microsoft Outlook on macOS, iOS, Android and Outlook on the web are not known to be affected at this time.
