Romanian authorities are investigating a 20-year-old who is suspected of hacking into several Pentagon and NASA servers and posting confidential data he retrieved from those servers on his blog, officials said Tuesday.

The suspect was identified as Razvan Manole Cernaianu, reportedly an information technology student known online as TinKode. Organized crime prosecutors allege Cernaianu also offered to sell an application that showed how he accessed the servers.

Prosecutors said in a statement that they are cooperating with FBI and NASA representatives.

The U.S. Embassy in Bucharest said Cernaianu "used sophisticated hacking tools to gain unauthorized access to government and commercial systems." The case demonstrates that "countries and agencies around the globe" could cooperate "to counter these types of threats," it said.
