Foreign government hackers caught secretly breaking into a U.S. national security network waged a 24-hour battle with cyber security officials trying to counter the cyber attack, the deputy director of the National Security Agency said Tuesday.
Richard Ledgett, a veteran cyber spy who will retire soon as NSA’s No. 2 official, said the virtual battle inside a U.S. government computer network in late 2015 represented a new phase in the ongoing covert cyber wars.
“It was a nation state actor who had gotten in and what we saw for the very first time, the adversary, once we detected them, instead of disappearing they fought back,” Ledgett said during a conference on cyber threats.
