Notes on /dev/kmem and /dev/mem


In the good old days, hackers were able to modify the kernel using the /dev/kmem device file. This file, which gave programmers a raw portal to the kernel memory, was eventually subject to various security patches and removed from many distributions. However, some distros still have it available to read from, which can be a powerful tool for detecting kernel malware, but it is not necessary as long as /proc/kcore is available. Some of the best work ever written on patching the Linux kernel was conceived by Silvio Cesare, which can be seen in his early writings from 1998 and can be found on vxheaven or on this link:
