National Security Council deputy national security adviser Anne Neuberger says White House will soon release details about Exchange attacks. Attacks targeted vulnerable on-premises Microsoft Exchange email servers at government agencies and other organizations. Microsoft issued patches for four vulnerabilities in certain versions of its Exchange email server that the company says were exploited by a China-based group its researchers called Hafnium. The Biden administration created a Unified Coordination Group to investigate the attacks shortly after they were identified, but the White House did not confirm that a Chinese group first exploited the vulnerabilities.”]
