Title: State-sponsored groups exploit bug in Microsoft Exchange servers
Description: The U.S. Department of Defense warned that multiple state-sponsored actors are exploiting a vulnerability in Microsoft Exchange servers. The bug was disclosed and patched in February, but many users out there have not updated their software. Attackers can send malicious, specially crafted requests to the Exchange control panel. The vulnerability allows adversaries to change serialized data to be unserialized, which allows them to run malicious code on the server’s backend at the system level.
