Earlier this week, Microsoft accused a Chinese hacking group known as “Hafnium” of breaching its Exchange Server email application. Microsoft had previously accused the company of attempting to steal information from infectious disease researchers, defense contractors, policy think tanks and non-governmental organizations.
Pentagon spokesperson John Kirby on Friday revealed the US Department of Defense was assessing its networks for possible damage after the Microsoft breach.
“We are also … taking all necessary steps to identify and remedy any possible issues related to the situation,” he added.
The latest statement by the Pentagon comes after White House press secretary Jen Psaki said that the Biden administration is monitoring the Microsoft breach, which had a “large number of victims,” the Hill reported.
“Everyone running these servers — government, private sector, academia — needs to act now to patch them. We are concerned there are a large number of victims and we are working with our partners to understand the scope of this. So it’s an ongoing process,” Psaki said, the Hill reported.
The Czech Republic’s National Office for Cyber and Information Security also released a statement Friday stating it would assisting organizations impacted by the hack, suggesting that the hack has had international ramifications.
Since the breach, Microsoft has updated its software.
