CLUJ, Romania, Nov. 16 (UPI) -- Romanian authorities say they've arrested a 26-year-old hacker accused of breaking into multiple NASA servers and causing $500,000 in damage.
Following an investigation by the Romanian Directorate for Investigating Organized Crime and Terrorism, Robert Butyka was arrested Tuesday in Cluj in western Romania, SecurityNewsDaily.com reported.
Butyka, who reportedly uses the online moniker "Iceman," is accused of hacking into several NASA servers beginning Dec. 12, 2010, allegedly destroying protected data and restricting access to it.
"Through criminal activity, the accused severely affected the operation of computer servers by introducing, modifying and damaging electronic data and restricting access to it," the directorate said in a statement.
Directorate agents said they seized several computers at his home during a raid.
Butyka is not the first Romanian hacker to break into computer systems belonging to NASA. The U.S. space agency is a common target for hackers looking to prove their skills, authorities said.
