Police in the U.K. have arrested a man in connection with the theft of source code from networking equipment maker Cisco Systems Inc. in May, a Scotland Yard spokeswoman confirmed Friday.
The Metropolitan Police Computer Crime Unit searched residences in Manchester, U.K. and Darbyshire, U.K. on Sept. 3., confiscated computer equipment and arrested a 20 year-old man suspected of committing "hacking offenses" under that country's Computer Misuse Act of 1990. While authorities could not discuss the specifics of the case, the arrest was linked to the Cisco source code, according to Julie Prinsep, a Yard spokeswoman.
The suspect has since been released on bail and is scheduled to appear before authorities at a London police station again in November, Prinsep said. Computer equipment seized in the searches is being forensically examined, she said.
Cisco did not immediately respond to requests for comment.
The arrest marks a major breakthrough in the case, which involves the posting of more than 800M bytes of source code from Cisco's Internetwork Operating System (IOS) to a Russian Web site in May.
IOS is a proprietary operating system that runs on much of the networking hardware that Cisco makes.
Malicious hackers made off with code for versions 12.3 of IOS after the thief compromised a Sun Microsystems Inc. server on Cisco's network, then briefly posted a link to the source code files on a file server belonging to the University of Utrecht in the Netherlands, according to Alexander Antipov, a security expert at Positive Technologies, a security consulting company in Moscow.
Antipov said he downloaded more than 15M bytes of the stolen code after an individual using the online name "Franz" briefly posted a link to a 3M-byte compressed version of the files in a private Internet Relay Chat forum on in May.
The link provided was only available for approximately ten minutes and pointed to a file on an FTP (File Transfer Protocol) server, ftp://ftp.phys.uu.nl, which belongs to the University of Utrecht in the Netherlands. That server is open to the public for hosting files of files smaller than 5M bytes, according to the University's Web page.
Antipov subsequently posted some of that code on a Russian security Web site, www.securitylab.ru, to call attention to the reported theft, but denied knowing Franz.
At the time, Cisco said it was working with the U.S. Federal Bureau of Investigation (FBI) to pursue the hackers. The FBI was not able to comment on the arrest Friday.
The arrest in the Cisco theft follows other recent successes in cybercrime cases. In June, the FBI announced arrests in the source code theft for a much-anticipated version of the popular computer game Half-Life from the network of game maker Valve Corp.
In May, German police arrested men in connection with creating the Sasser Internet worm and a Trojan horse program called Agobot. On Sept. 9, prosecutors in Verden, Germany, indicted an 18-year-old student in the Sasser worm case.
