Tech Emotions

Interesting take on hacking hardware to control the Linux based machined. But I think that the same technology can also be used by organizations or governments to safe guard the machines, by hot patching the Linux Kernel with immediate fixes to major security breaches.

Our goal is to produce a PCI card which, when present in a machine running Linux, modifies the kernel so that we can control the machine remotely over the Internet. We’re going to make the simplifying assumption that we have a virtual machine which is a replica of the actual target machine. In particular, we know the architecture and exact kernel version of the target machine. Our proof-of-concept code will be written to only work on this specific kernel version, but it’s mainly just a matter of engineering effort to support a wide range of kernels.
