Hi, Today I cleaned up a freshly rooted (old and unmaintained) RedHat box. Found a "posiden rootkit" with the usual stuff inside (modified ps, top, find, netstat, ifconfig, syslogd, sshd; plus linsniffer, z2, wted, ..) Rootkit config files were named /dev/ptyp, /dev/ptyr etc. Nothing fancy.. Now the fun part: Imagine my surprise finding /sbin/ifconfig being a text file that said: "This file was infected with a virus. The file was quarantined by Norton AntiVirus. Fri Oct 26 15:53:10 2001" Sure enough, this ifconfig "binary" was already included in the rootkit tar file. As we have never heard of Norton AntiVirus for Linux, we tend to believe that poor kiddie downloaded the rootkit to his Windows box, where his own Antivirus software shot himself in the foot. Stupid, eh? ciao, chakl -- I don't know why more people don't use tcpdump to debug these sorts of situations...does it need to be called something else? ipdebug? -- Darren Reed ---------------------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
