    Crackers can cause their software to be run by adding entries to /etc/inittab, a file frequently missed by administrators. I told folks to discount any change which required kernel modifications. A change to the MBR probably doesn't qualify in that . . . Crackers can cause their software to be run by adding entries to /etc/inittab, a file frequently missed by administrators. I told folks to discount any change which required kernel modifications. A change to the MBR probably doesn't qualify in that regard, but it would certainly seem out of scope nonetheless.[3] Similarly, a change to the bootloader or initrd ram disk[4] fall under kernel changes to some degree, and thus weren't the correct answer, based on my phrasing.

    Many folks suggested that it was root's .bashrc, or global /etc/profile and similar files that was the culprit. By logging in, root's shell would execute commands that were hidden in those files. That's definately a possibility, but the fact that moniker had PID 15 meant that it had to have started before root logged in, so that's not the culprit.
