A Cyber-Attack On an American City 461

Posted by timothy from the if-by-one-day-you-mean-already dept.
Bruce Perens writes "Just after midnight on Thursday, April 9, unidentified attackers climbed down four manholes in the Northern California city of Morgan Hill and cut eight fiber cables in what appears to have been an organized attack on the electronic infrastructure of an American city. Its implications, though startling, have gone almost un-reported. So I decided to change that."

"Good Enough" Computers Are the Future 515

Posted by timothy from the adequate-for-light-word-processing-and-small-sums dept.
An anonymous reader writes "Over on the PC World blog, Keir Thomas engages in some speculative thinking. Pretending to be writing from the year 2025, he describes a world of 'Good Enough computing,' wherein ultra-cheap PCs and notebooks (created to help end-users weather the 'Great Recession' of the early 21st century) are coupled to open source operating systems. This is possible because even the cheapest chips have all the power most people need nowadays. In what is effectively the present situation with netbooks writ large, he sees a future where Microsoft is priced out of the entire desktop operating system market and can't compete. It's a fun read that raises some interesting points."

Intel Cache Poisoning Is Dangerously Easy On Linux 393

Posted by timothy from the anything-you-set-your-mind-to dept.
Julie188 writes "A researcher recently released proof-of-concept code for an exploit that allows a hacker to overrun an Intel CPU cache and plant a rootkit. A second, independent researcher has examined the exploit and noted that it is so simple and so stealthy that it is likely out in the wild now, unbeknownst to its victims. The attack works best on a Linux system with an Intel DQ35 motherboard with 2GB of memory. It turns out that Linux allows the root user to access MTR registers incredibly easily. With Windows this exploit can be used, but requires much more work and skill and so while the Linux exploit code is readily available now, no Windows exploit code has, so far, been released or seen. This attack is hardware specific, but unfortunately, it is specific to Intel's popular DQ35 motherboards."
