Hackers Seize UK Military Satellite - Report February 28, 1999 6:42am Reuters LONDON (Reuters) - Hackers have seized control of one of Britain's military communication satellites and issued blackmail threats, The Sunday Business newspaper reported. The paper, quoting security sources, said the intruders altered the course of one of Britain's four satellites which are used by defense planners and military forces around the world. The sources said the satellite's course was changed just over two weeks ago. The hackers then issued a blackmail threat, demanding money to stop interfering with the satellite. ``This is a nightmare scenario,'' said one intelligence source. Military strategists said that if Britain were to come under nuclear attack, an aggressor would first interfere with military communications systems. ``This is not just a case of computer nerds mucking about. This is very, very serious and the blackmail threat has made it even more serious,'' one security source said. Police said they would not comment as the investigation was at too sensitive a stage. The Ministry of Defense made no comment.
