SHANGHAI — A massive cyberattack that lasted up to five years infiltrated computers and stole data from the United Nations and a wide range of governments and American corporations, according to a report released Wednesday by security experts in the United States.
The American security company McAfee called it a highly sophisticated cyberattack that appeared to have been operated by a government body. But McAfee, which was recently acquired by Intel, declined to say which country it believed was behind the attack.
“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 Wednesday.
