Russian security Web site SecurityLab is reporting that the source code for Cisco Systems Inc.'s main networking device operating system was stolen on Thursday. According to the report, criminal hackers broke into Cisco's corporate network and stole 800MB of source code for IOS 12.3 and 12.3t (an early deployment version containing features not found in the vanilla 12.3 version). In addition, a 2.5MB sample of what is supposedly IOS code was released on an Internet Relay Chat channel as proof of the alleged theft.
IOS 12.3 is the newest main version of San Jose, Calif.-based Cisco's popular operating system. It's used across the company's networking line, including in home office routers (the 800 Series); those for branch offices (the 3700 Series); and those that comprise the Internet backbone (the 7000 Series). Other routers that use the operating system include the 1700, 2500, 2600 and 3600 Series.
