Your descriptive profile is incorrect. I know this because of some first hand experience. A hacker put linsniffer on my system and it repeatedly broke email sessions and deleted the inbox messages. One time when I was rebooting I noticed the error linsniffer can't run. So I search my system documentation for linsniffer using locate man and info. locate was the only tool to find anything and it was a subdirectory that couldn't be deleted off of my /dev directory /dev/ida/linsniffer that contained lots of files. So I wiped the speakup system out and later did some web research on linsniffer. I found a site called http://www.attrition.org that referenced linsniffer. So these hackers are writing their own web sites too and making the information and probably the scripts available to anyone that can do a web download.
