An attack demonstrated by security company CrowdStrike at the RSA Conference today in San Francisco is one that brings to mind the self-destructing electronics typically found in spy movies. By introducing a bogus firmware update to the APC embedded controller of an Apple computer running OS X the firm was able to bump the CPU frequency and turn off the fans. The company stopped short of setting the machine on fire, which it claims is possible, due to the public setting and settled for merely "frying the machine." CrowdStrike sees this type of attack as a real possibility going forward as data and hardware will be unrecoverable due to the physical destruction.
