President Barack Obama has said the US is considering putting North Korea back on its list of terrorism sponsors after the hacking of Sony Pictures.
A decision would be taken after a review, he said, calling the attack an act of cyber-vandalism, not of war.
North Korea denies the attack over The Interview, which depicts the fictional killing of its leader Kim Jong-Un.
Sony cancelled the Christmas Day release after threats to cinemas. It is considering “a different platform”.
In a CNN interview, President Obama described the hacking as a “very costly, very expensive” example of cyber-vandalism.
He said US officials would examine all the evidence to determine whether North Korea should be put back on the list of state sponsors of terrorism.
“I’ll wait to review what the finding are,” Mr Obama said, adding that he did not think the attack “was an act of war”.
