In early April 2010, for the first time in history, an American geostationary satellite has gone “rogue.” The satellite, known as the Galaxy 15, is no longer responding to command and control communications from its legitimate owner, the Intelsat corporation. Moreover, the satellite has left its assigned duty location and is now drifting uncontrolled through space. While mis-orbiting and crashed satellites are not a new phenomenon, they usually cease functioning and stop transmitting when leaving orbit and hurtling towards earth. What makes the Galaxy 15 case so unique, is that the satellite’s systems are fully functioning, with its telecommunications payload (the equipment that relays customer’s transmissions around the globe) fully “powered-on.” Despite 150,000-200,000 attempts to reboot system’s software, the satellite is refusing to accept commands from Earth. The primary threat in this case is not from the satellite crashing directly into another satellite, but instead interfering with other global satellite [...]

For some time now, experts in the information security community have been concerned about the possibility of mobile phone botnets: now it appears these fears may have been well-grounded, as suggested in the article below. While there are billions of desktop and portable computers in the world, there are billions more mobile phones. As the computing power of mobile smartphones increases, they have been transformed from simple hand-held devices used solely for placing voice calls into highly capable full-fledged portable computers. In fact today’s iPhone likely has more processing power than most desktop machines had just a few short years ago. These developments, driven by Moore’s law, have created a fundamental shift in the nature of computing and how people access the global power of the Internet. As portable computing devices become more powerful, end-users are storing serious amounts of information on them. While one was unlikely to “lose” [...]
