Network (in)Security Interesting hacks and cracks. Info on firewalls, TCP/IP, encryption, networks, and security. The ins and outs of the phone system, caller services, how things work, what's illegal and what's not, cellular phones, beepers, telephony legislation, the PUC, ISDN, taps, who's listening, and switches. Talking about phones, hacking systems, technical advice, and such is completely LEGAL in the United States -- it's covered by the First Amendment. What's illegal is conspiracy to commit a crime. So if you say something like "Meet me at 2am so we can crack a can" or "I changed my cell phone's number myself" you are criminally liable. Stating "You can crack a can by doing thus-and-so" or "If you wanted to change a cell phone's number, you could do it like so" is perfectly OK. Posting passwords, calling card numbers, or credit card numbers is forbidden on this network. Posting such info will get you booted off the net.

Default HTS Steganography challenges

I've always been interested in steganography, and this seems like a pretty good place to get started. The problem though, is just that. Getting started. Can't seem to get moving...

I've done a bit of reading, and I believe I understand the principles of a few methods of hiding text in bmp's. However I'm not sure how to go any further.

I need to see the RGB values of each pixel in an image. Specifically the last digits. Is there a method/program for me to do this?

Anyone want to join in with the challenges?

Currently reading a report released by the US air force. 180 pages though, so wont finish reading it for a while.
