Ethics of Releasing Non-Malicious Linux Malware? 600

buchner.johannes writes "I was fed up with the general consensus that Linux is oh-so-secure and has no malware. After a week of work, I finished a package of malware for Unix/Linux. Its whole purpose is to help white-hat hackers point out that a Linux system can be turned into a botnet client by simply downloading BOINC and attaching it to a user account to help scientific projects. The malware does not exploit any security holes, only loose security configurations and mindless execution of unverified downloads. I tested it to be injected by a PHP script (even circumventing safe mode), so that the Web server runs it; I even got a proxy server that injects it into shell scripts and makefiles in tarballs on the fly, and adds onto Windows executables for execution in Wine. If executed by the user, the malware can persist itself in cron, bashrc and other files. The aim of the exercise was to provide a payload so security people can 'pwn' systems to show security holes, without doing harm (such as deleting files or disrupting normal operation). But now I am unsure of whether it is ethically OK to release this toolkit, which, by ripping out the BOINC payload and putting in something really evil, could be turned into proper Linux malware. On the one hand, the way it persists itself in autostart is really nasty, and that is not really a security hole that can be fixed. On the other hand, such a script can be written by anyone else too, and it would be useful to show people why you need SELinux on a server, and why verifying the source of downloads (checksums through trusted channels) is necessary. Technically, it is a nice piece, but should I release it? I don't want to turn the Linux desktop into Windows, hence I'm slightly leaning towards not releasing it. What does your ethics say about releasing such grayware?"

Money is the root of all evil, and man needs roots.
