Razvan Manole Cernaianu, perhaps better known as Tinkode, was recently arrested in Romania. He gained notoriety after allegedly compromising a number of websites, including those of NASA, the European Space Agency, and Sun Microsystems. The 20 year-old from Timisoara, Romania hacked into servers belonging to the U.S Army and stole confidential information. He later posted video demonstrations of the hack on his blog, where visitors could also buy a computer program that could hack sites in a similar fashion.
