The hacker altered the DNS tables and left a passwd cracker in /bin. There were DNS db files that were invisible to "/bin/ls", but they show up from "od" dump of the directory. Can someone help me to find out how he got in initially? What should I do at this point? Should I wipe the disk on this system?
