The Biden administration is working to formally attribute the exploitation of vulnerabilities in Microsoft\u2019s Exchange Server application, which left thousands of organizations vulnerable to attack, \u201cin the coming weeks,\u201d a top official said Tuesday.<\/p>\n
\u201cI think you saw the national security adviser\u00a0Jake Sullivan<\/a>\u00a0say that we will attribute that activity, and along with that of course determine what needs to do as a follow up from that and I think you\u2019ll be seeing further on that in the coming weeks,\u201d Anne Neuberger, the deputy national security advisor for cyber and emerging technology, said during a virtual event hosted by the Silverado Policy Accelerator.<\/p>\n Neuberger\u2019s comments came months after Microsoft\u00a0announced the discovery<\/a>\u00a0of new vulnerabilities in its Exchange Server program, and assessed with \u201chigh confidence\u201d that a hacking group known as \u201cHAFNIUM,\u201d a Chinese state-sponsored group, was exploiting these vulnerabilities.<\/p>\n According to Neuberger, around 140,000 organizations were left vulnerable to attack by HAFNIUM or other hacking groups. Tuesday, the official praised Microsoft for quickly releasing a patch that reduced this number to less than 10 vulnerable groups in a week.<\/p>\n
