We’re not pointing fingers at anyone but we believe it was a nation-state,” Dmitri Alperovitch, McAfee’s vice president of threat research and the lead author of the report, said in a telephone interview on Wednesday. China has repeatedly been the focus of suspicion in such cases.
The report comes after high-profile cyberattacks aimed at the International Monetary Fund, Sony and the Lockheed Martin Corporation, America’s largest military contractor.
McAfee, which was recently acquired by Intel, said it released the report to coincide with the start of the annual Black Hat technical security conference in Las Vegas. Briefings at the conference are scheduled to be delivered Wednesday and Thursday. Details of the study were first published on the Web site of Vanity Fair.
