WASHINGTON (Reuters) - The White House is closely tracking an emergency patch Microsoft Corp has released, U.S. national security adviser Jake Sullivan said on Thursday, after an unknown hacking group recently broke into organizations using a flaw in the company's mail server software.
"We are closely tracking Microsoft’s emergency patch for previously unknown vulnerabilities in Exchange Server software and reports of potential compromises of U.S. think tanks and defense industrial base entities," Jake Sullivan, President Joe Biden's national security adviser, said on Twitter.
