Full disclosure is a "lightly moderated" security mailing list generally used for discussion about information security and disclosure of vulnerabilities. The list was created on July 9, 2002 by Len Rose and was administered by Len Rose, who later handed it off to John Cartwright. After Len Rose shut down netsys.com, the list was hosted and sponsored by Secunia. The Full Disclosure mailing list was originally created because many people felt that the Bugtraq mailing list had "changed for the worse".
