The Moscow bureau of The New York Times was the target of a cyberattack, though there are no indications yet that the hackers were successful, according to the newspaper.
The hackers are believed to be Russian, the newspaper said Tuesday evening. It quoted a spokeswoman for the newspaper as saying that it had not hired outside firms to investigate the attempted breach.
Earlier in the day, CNN reported that the FBI and other U.S. security agencies were investigating attacks by hackers, thought to be working for Russian intelligence, that targeted reporters at the New York Times and other U.S. news organizations. CNN quoted unnamed U.S. officials briefed on the matter.
