sub7 huh? lol that takes me back, the path you took is better than a lot did (from white to black), Its also good that you're sharing the knowledge. I respect that. hmmm i'm not sure whether or not to say anything about history, but I'll just mention couple of silly stuff I did, actually this is a good thread this reminds me on how I decided to become a security pro, it started when I didn't like some modules they taught at school, so hacked the teacher's computer then copied the exam papers. after that I started to do some basic security stuff for my friends. took it more serious then studied more about it, then became more of a white hat.

any other ideas? Pls let me know

back when i was a young, dumb teenager with no morals, i did some not-so-savory things. the movie war games prompted me to write my first tool, a war dialer (with a 300 baud modem on a C64), that tool eventually morphed in to something much more sinister. When one of my best friends at the time got busted in Op. Sundevil, I went dark for about a decade (figured my name was on several government lists, may still be to this day), then came back all white hatted up with ethics and morals.

bunch of nerds, I was going after girls at 15 :-p  I keed I keed, but seriously, I was all up in the p....

Actually I wasn't really into computers much when I was younger.  I really didn't get into them until college.  I found I had a latent knack for fixing them.  Took a job on campus as an installer for the Info Systems repair depart.  Basically "I pick things up and put them down."  Until I came across my first actual problem then needed fixed.  It was a "simple" job to install a new desktop in one of the dorm offices.  Connected everything up but no network access.  After a couple hours of troubleshooting (bare in mind I knew nothing about the basics of networking), we realized it was nothing I could fix.  Finally got TelCo involved and we found it was a bum connection down in the data closet.  Based on my troubleshooting steps I used the boss was impressed and moved me to full fledged repair tech.  During this time I was messing around a lot with our VMS/VAX system, using Lynx and trying out different things, nothing really hackable, but it was fun to learn it.  Eventually I became pretty good and got promoted over to the Info Systems dept to work with the Sys Admin.  Got my first taste of major systems work - NT networks, Exchange migration, building a back end program to the computer lab network ID creator and an app to verify users when they call the faculty helpdesk.  It was all very cool.

After working as a sys admin for a couple years, I moved into consulting and then finally made the leap to move into InfoSec.  The only major difference is that I now focus on security centric solutions.  Right now I am interested in malware analysis.  I love seeing how it ticks and the techniques used to try and hide it from detection.

I do think more and more youngeters today are involved in black hat stuff. I dont know if this is down to lack ifnormation on what is bad and what is good or if they think they so young the law wont do anything to them.

I also think so many youngeters want to get into security and find it hard they get frustrated and end up getting involved in anoymouse or trying hack companies website to show off their skills when this has the revers affect for an employee.
