The mysterious hacker is not yet tired of releasing latest Sony email leaked as new document revealed the entire email account of Sony Pictures Entertainment chairman and CEO Michael Lynton, said by Hollywood Reporter.

The people behind this Sony email hack attack call themselves Guardians of Peace. The previous email leaked is about the conversations of studio co-chairman Amy Pascal and producer Scott Rudin, dising some celebrities (except Channing Tatum email conversation). Most of the leaked conversations is about dealing with the talent and filmmaking process. However, the latest Sony email leaked revealed Lynton's private documents including key financial strategy and details about SPE as well as perhaps parent company Sony Corp.

THR reported that CEO's email account contains 12,466 messages, including deleted messages, dating from Nov. 12, 2008, to Nov. 21, 2014, three days before the hack was first noticed by the studio.

Last Tuesday, there was an email message sent to reporters with links to peer-to-peer sites that contained part one of GOP's "Christmas gift." The message reads:

"We have already promised a Christmas gift to you. This is the beginning of the gift. ... Soon all the world will see what an awful movie Sony Pictures Entertainment has made. The world will be full of fear. Remember the 11th of September 2001. We recommend you to keep yourself distant from the places at that time. (If your house is nearby, you'd better leave.) Whatever comes in the coming days is called by the greed of Sony Pictures Entertainment. All the world will denounce the SONY."
