Recent reports have highlighted a concerning trend where cyber attackers are increasingly exploiting Microsoft Graph API as a tool for stealthy operations. Notably, threat groups like APT28, REF2924, and Red Stinger have been using this API to bypass detection mechanisms and facilitate communication with their command-and-control centers, which are hosted on Microsoft's cloud services. This exploitation allows for covert data theft and malware communications, posing significant challenges to cybersecurity defenses.
