Hackers, who're reportedly linked to Russian intelligence, have been targeting reporters at the New York Times and other US news organizations, according to US officials.
The intrusions are being investigated by theFBI and other agencies.
Investigators say that Russian intelligence is likely behind the cyber breaches over recent months.
They alsolike them as the culprits behind hacks that have focused on Democratic Party organizations.
The FBI did not comment on the situation and the New York Times spokeswoman would not confirm the attacks or investigation.
Attention has grown on the hacks thought to be carried out by Russians since Wikileaks released a trove of emails stolen from the DNC in the weekend before theDemocratic Party's convention to nominate Hillary Clinton for president.
