Sony's president and chief executive Kazuo Hirai has used CES 2015 in Las Vegas to discuss the impact of the Guardians of Peace hack on its servers and systems.
Hirai said that he is proud of Sony and its reaction to the hacking incident, and that the company will always strive to protect freedom of speech.
He did not dwell on the details, nor did he name any suspects, despite many suggestions that North Korea was behind the attack.
"Sony, former employees and current employees were the victims of one of the most vicious and malicious cyber attacks in recent history," Hirai said in a speech at CES (below).
"I have to say that freedom of speech, freedom of expression, freedom of association - these are very important lifelines for Sony and our entertainment business."
The hack late last year exposed personal details on celebrities, Sony's business partners and members of staff, current and old.
Sony has not made much comment on the attack so far, but Hirai said that a lot of effort is going into the recovery process.
He explained that, despite the threats against Sony and several cinemas, the company has been able to release the controversial film The Interview to some success.
"I have to say that I'm very proud of all the employees, and certainly the partners who stood up against the extortion efforts of criminals, and worked tirelessly, sometimes for days on end, to bring you The Interview," he said.
While the US has named North Korea as being behind the attack others in the security community have questioned just how certain it can be on this assumption, especially as some of the information used to arrive at this decision remains secret.
