A British hacker has pleaded guilty to accessing systems related to a U.S. Defense Department satellite, which the Pentagon claims cost $628,000 to mitigate.

Sean Caffrey, a 25-year-old resident of Sutton Coldfield, England, admitted that he stole data concerning 800 users of a satellite communications system and 30,000 satellite phones in 2014, the United Kingdom's National Crime Agency said Thursday.

British authorities traced the attack to Caffrey's internet address and found that an online messaging account linked to the attack was operated from his computers, officials said.

“No one should think that cyber crime is victimless or that they can get away with it," Janey Young, investigations manager at the National Crime Agency, said in a statement.

Officials said the systems attack took place in June 2014. Caffrey was arrested the following March.

“We’re working to keep the internet a safe space for people who use it legitimately,” Young said.
