White House Is Concerned As Microsoft Email Breach Spreads

A hack of Microsoft’s email server is not just another data breach. It was apparently caused by China-based hackers and is being monitored by the White House even as it spreads to Europe. 

“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,” National Security Advisor Jake Sullivan tweeted, according to Reuters. 

In a blog post on Tuesday, Microsoft reported that a threat actor exploited three vulnerabilities to “access on-premises Exchange servers which enabled access to email accounts, and allowed installation of additional malware to facilitate long-term access to victim environments.”
