Cyberattacks on dozens of U.S. firms have been traced back to a small, nondescript Chinese military unit quietly working in a similarly unimpressive setting — a dull office building just outside Shanghai.
"It is time to acknowledge the [cybersecurity] threat is originating from China," Mr. McWhorter said. "The issue of attribution has always been a missing link in the public's understanding of the landscape of cyber espionage. Without establishing a solid connection to China, there will always be room for observers to dismiss [hackers'] actions as uncoordinated, solely criminal in nature, or peripheral to larger national security and global economic concerns."
"The decision to publish a significant part of our intelligence about Unit 61398 was a painstaking one," said Dan McWhorter, Mandiant's managing director for threat intelligence, referring to a special unit of China's People's Liberation Army (PLA) that has carried out the cyberattacks.
