From the doc: 'This is a hacked version of wu-ftpd 2. . But it doesn't mean that we only can use it as that particular version. Just open the / /newvers.sh file and put in what ever banner you want. Not an really old version due to there are really some changes that will be noticed kinda easy Compile it as usual and put it over the old bin. Now telnet to the daemon to use the backdoor. NOT ftp to it Login with the user anonymous ( i have used this to hide it abit ) and voila you are now root.'
