Swedish teen arrested for hacking internet code

WASHINGTON - Cisco Systems in the US said authorities in Sweden had detained a person for stealing its source code, the basic instructions for the machines that direct internet traffic around the globe.

"We are aware that a person has been detained in Sweden related to the IOS source code theft and are encouraged by this action," the San Jose, California, company said in a statement.

Swedish police have declined to say whether their investigation of a 16-year-old boy is related to a May 2004 incident that exposed the inner workings of Cisco's internetworking Operating System, or IOS.

The FBI said in a statement it had been working with authorities in Sweden and Britain to track down the culprit. "As a result of recent actions, the criminal activity appears to have stopped," it said.

The New York Times reported that the Cisco theft was part of a broader hacking campaign that targeted computer systems run by US universities and government agencies.

Several supercomputer labs in April 2004 reported that computers connected to the high-speed TeraGrid network had been breached.

A spokeswoman for the White Sands Missile Range in New Mexico confirmed that the facility had experienced an intrusion around the time that Cisco reported its breach, but said no sensitive information was obtained.

"Basically, they got into some local weather forecasts," spokeswoman Monte Marlin said.

Source code, the underlying blueprint of computer software, determines how programmes work. Companies like Microsoft Corp zealously guard their source code because they consider it the lifeblood of their business.

Cisco said last May that portions of its IOS source code had been copied from its internal systems and posted on a foreign website for several days, where presumably other hackers could examine it closely for security flaws.

The company said at the time that the breach would not put customers' equipment at risk.

Swedish police have told local media that a suspect has been under investigation since last year for hacking into computers at Uppsala University, but have declined to say whether he participated in the US attacks.

Authorities in Britain arrested a 20-year-old man last September in connection with the Cisco hacking, but no charges have been filed.
