According to Sandra Joyce, Mandiant’s head of global intelligence, the adversaries responsible for the most zero-day exploits this year are Chinese advanced persistent threat (APT) groups. “Some of them have reached a level of sophistication that allows them to exploit a zero-day vulnerability in a few hours without getting detected – and sometimes it takes us, defenders, a long time to figure out how they did it,” she said during the Google Cloud’s Mandiant mWISE conference, held in Washington, DC from September 18 to 20, 2023.
