From monitoring router logs, I have found that sometimes a machine is rooted more than once. The first kiddie roots the machine, installs a rootkit, but doesn't fix the vulnerability. A subsequent cracker roots it again, installing a different rootkit. It is not a feint, just the fact the rooting a box doesn't necessarily fix the vulnerability. Oh yes, it was an IRIX box rooted with telnet vulnerability.

Has anybody on this list detected such > kind of "feints"? I posted to usenet last year with the same question, because one of the machines I tend got rooted. In response, some guy claimed he found a rootkit that had at least two layers: http://groups.google.com/groups?hl=en&selm=9h6gsa%2414r%241%40bob.news.rcn.net I'm not at all sure I believe this story: IRIX is pretty obscure, and not very widely used. Why would anyone go to the effort of doing a "feint" rootkit to mask a "real" rootkit for so few targets? ---------------------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
