The North Korea-funded hackers, who recently targeted the Sony Pictures Entertainment movie studio, reportedly have leaked the phones numbers of Brad Pitt, Julia Roberts, Tom Hanks and several other Hollywood stars.
The hacking group also have released the details of the aliases used by the Hollywood actors. Besides Brad Pitt, Julia Roberts and Tom Hanks, the group also have leaked the information of Daniel Craig, Natalie Portman, Tobey Maguire, Jonah Hill and Sarah Michelle Gellar.
The hacking group, the Guardians of Peace, has targeted the Sony Pictures Entertainment movie studio for the last two weeks. In the latest information leak, they have also released confidential "popularity polls" detailing approval ratings and awareness ratings for hundreds of A-list celebrities in different markets around the world, Fusion reported.
North Korean officials have denied accusations that they launched the massive hacking operation in retaliation for the studio making, "The Interview", which stars James Franco and Seth Rogen as TV journalists recruited by the CIA to assassinate Kim Jong-un. The comedy is due to be released in cinemas in the US on Christmas Day.
A message attributed to the hackers was released on Monday demanding Sony not to show "the movie of terrorism which can break the regional peace and cause the war!" The message added: "You, Sony and FBI, cannot find us."
Pyongyang has previously referref to "The Interview" as "an undisguised sponsoring of terrorism" and "an act of war".
Despite denying its involvement, KCNA, which is North Korea's state-run propaganda arm called the hacking into the SONY Pictures "a righteous deed of the supporters and sympathisers with the DPRK."
A CNN Money report citing experts stated that the North Korean involvement was clear from the fact that the malware used in this attack and a different cyber blitz against South Korea both were written in Korean, an unusual language in the world of cyber crime.
In June, North Korea said it would view the Seth Rogen and James Franco movie as an "act of war." Reports in the state-sponsored North Korean media said the movie depicts "a terrorist act while hurting the dignity of the supreme leadership of the DPRK."
