( CNN ) British law enforcement officers have arrested a 23-year-old man suspected of hacking the U.S. Department of Defense and swiping data from a satellite-based system used by the military to communicate with people worldwide , UK authorities said Friday . This arrest was one of 56 made this week in 20 separate operations conducted by regional organized crime units , Metropolitan Police officers and others . The others caught range from a family of suspected fraudsters and a 16-year-old believed to be behind hundreds of cyberattacks , according to Britain 's National Crime Agency . Yet the arrest that the agency highlighted most was the one that targeted the world 's most powerful last June 15 . On that date , someone hacked into the U.S. Department of Defense 's servers and got data related to its `` Enhanced Mobile Satellite Services '' system . This included contact information -- including their names , emails and phone numbers -- of about 800 people and info on approximately 34,400 devices , the National Crime Agency reports . None of the hacked material was considered confidential , nor did it apparently include `` sensitive data '' or anything that `` compromises U.S. national security interests , '' the British agency said . Still , the person responsible for the hack cryptically played it up big in a post to Pastebin , a website that allows for anonymous posts . Alongside screenshots of the dashboard used to control the Defense Department database , the hacker wrote , `` We smite the Lizards , LizardSquad your time is near '' in apparent reference to a notorious band of black-hat hackers . `` We 're in your bases , we control your satellites , '' the hacker adds . `` The missiles shall rein ( sic ) upon they who claim alliance , watch your heads ... We 're one , we 're many , we lurk in the dark , we 're everywhere and anywhere . '' The 23-year-old suspected hacker was not identified by name , with the UK National Crime Agency saying only that he was arrested Wednesday morning in Sutton Coldfield , a Birmingham suburb in the West Midlands region . The U.S. military has been targeted by hackers before . Some of those actions have been blamed on ISIS sympathizers , like the January temporary takeover of the U.S. Central Command 's Twitter account and YouTube page . And last year , U.S. federal officials accused four men of hacking into computer networks of the U.S. military and Microsoft and stealing more than $ 100 million worth of software , some it related to the video game `` Call of Duty : Modern Warfare 3 . '' There 's no indication that the June hack had anything to do with ISIS or involved the theft of anything of much monetary value . Still , hacks from groups such as Lizard Squad and Anonymous can have a significant impact . Jeffrey Thorpe , special agent in charge with the U.S. Department of Defense Criminal Investigative Service ( DCIS ) , said in the UK government statement that `` this arrest underscores DCIS commitment and the joint ongoing efforts among international law enforcement to stop cyber criminals in their tracks . '' `` DCIS special agents will use every tool at their disposal to pursue and bring to justice those who attack the Department of Defense , '' Thorpe said . CNN 's Ed Payne and Claudia Rebaza contributed to this report .
The 23-year-old man was one of dozens arrested in similar operations around Britain . Police said the operation had been launched after a tip-off from an anonymous caller who claimed to have information about a planned attack on London Underground trains.
