North Korean hackers targeted a British television company making a drama about the country, it has emerged.
The series - due to be written by an Oscar-nominated screenwriter - has been shelved.
In August 2014, Channel 4 announced what it said would be a new "bold and provocative" drama series.
Titled Opposite Number, the programme's plot involved a British nuclear scientist taken prisoner in North Korea.
The production firm involved - Mammoth Screen - subsequently had its computers attacked.
The project has not moved forward because of a failure to secure funding, the company says.
North Korean officials had responded in anger when details of the TV series were first revealed. Pyongyang described the plot as a "slanderous farce" as it called on the British government to pull the series in order to avoid damaging relations.
The North Koreans did more than protest though - they hacked into the computer networks of the company behind the show.
The incident was first reported by the New York Times, which cited Channel 4 as the main target. However, the BBC understands that it was actually Mammoth Screen that was hit by hackers.
