Where I had a problem with your descriptive profile was that you originally neglected to state that some of those crackers put up web sites and make their techniques generally available to the internet. A white hat wouldn't have much need to do something like that, even if the large corporations would like to sweep security problems under the rug it's possible to not only find people in government installations who will not only give them a fair hearing but will also even go so far as to verify their work and when that work is verified security-related clauses of contracts for hardware and software get updated and then the corporations do listen since failing to do so could loose them business and profits from government sales. We are not all that large of a consumer, but Government is another matter and it's like E. F. Hutton in that when it talks to contractors and corporations they listen.
