A 20-year-old hacker who goes by the Internet name TinKode was arrested recently by Romanian police after he bragged about hacking into Pentagon and NASA computer systems.

Razvan Manole Cernaianu is accused of revealing security holes and publishing information about SQL injection vulnerabilities in those agencies, SCO Online reported.

The Romanian Directorate for Investigating Organized Crime and Terrorism said Cernaianu also offered a computer program on his blog that could be used to hack into websites and published a video showing Internet attacks he had made against the U.S. government.

The FBI and NASA assisted in the investigation. The U.S. Embassy in Bucharest said Cernaianu used, "advanced hacking tools to gain unauthorized access to government and commercial systems."

Cernaianu allegedly hacked into a computer server at NASA's Goddard Space Flight Center last April, and posted a screen grab that showed files connected to confidential satellite data.
