Old Intel chips are vulnerable to a fresh security exploit
If you have an old, Intel-based computer hanging around, you might want to get rid of it post-haste. Security researcher Chris Domas has discovered a vulnerability in the x86 architecture of Intel processors made between 1997 and 2010 (pre-Sandy Bridge) that lets an attacker install software in a chip's protected System Management Mode space, which governs firmware-level security. Yes, that's as bad as it sounds: an intruder could not only take more control than you typically see in attacks (including wiping firmware), but infect your PC even if you wipe your hard drive and reinstall your operating system. Domas has only tested against Intel-made CPUs so far, but AMD processors could be vulnerable as well.
