Two teenagers hacked T-Online, the online service run by Germany's national telephone company, and stole information about hundreds of bank accounts.
The two 16-year-old hackers bragged about their exploits to the German magazine CT, calling Deutsche Telekom's security for the online service "absolutely primitive," according to a report by Agence France-Presse.
The attack comes on the heels of the Justice Department's arrest of three Israeli teenagers in connection with a string of break-ins of computer networks belonging to U.S. and Israeli governments, as well as those of businesses and educational institutions in the United States and abroad.
Hacking has become an international concern as more and more information is placed on the Internet and other computer networks. The fact that teenagers are the suspects in these latest attacks raises fears even more, underscoring the vulnerability of extremely sensitive information to clever youngsters looking for a thrill.
The German teens played online games for free upon breaking into the system, and later stole the financial data, which they said they destroyed without using.
Eric Danke, director of T-Online, told Agence France-Presse the incident was "very serious," and that the service is planning to beef up security.
