The Edge of I-Hacked

from Iron Geek

A cryptographic hash function takes an input and returns a fixed size string that corresponds to it, called a hash. Cryptographic hashes have a lot of uses, some of which are: detecting data changes, storing or generating passwords, making unique keys in databases and ensuring message integrity. This video will mostly cover detecting file changes, but I hope it gets your mind going in the right direction for how hashes can be used. Specifically covered will be tools for creating MD5 hashes in Windows and Linux.

After spending a few days at Shmoocon, I have officially claimed the title Badge Hacker or maybe ConSocial. The talks were very educating and ranged from “almost hacking your own company” to “0wn1ng a business man every which way”. It was great to see that what is being exposed is actually being used to make change. Deviant of http://deviating.net/lockpicking/topics.html spoke out that companies such as Master Lock are making changes to their locks after exposing how easy it is to bump a lock.

I meet up with Johnny Long and we chatted about his new book and how 100% of his proceeds will be going to Africa. We hooked him up with some i-hacked.com swag for his new foundation hackers for charity. I did meet up with Muts from offensive-security who did show off some of his bad ass BackTrack skills. I must thank him for his time and the swag. If you want Back Track training offensive-security is the place to go.

Later that night I met up with the pod cast crew of hak5. After many “non-alcoholic” (yeah right) drinks I talked everyone into crashing “katsucon”. For those like my self that have no idea what the hell I am talking about, it’s a con for animation. To make a long evil story short – we got in, we partied like rock stars and we were amazed at the huge arcade that they had. Props to the DJ of katsucon who mixed in samples of Anonymous. Check back soon for the video of the CON.

Eric D. Schabell » Linux courses
The following Linux courses have been created by me, released under the GFDL . They can be viewed in slide format online, but for a more complete introduction to the material I am available for teaching contact information is listed at the bottom of this page. I have taught these courses commercially…

On August 10, 2006, authorities in Great Britain announced that they had arrested several people in connection with a plot to attack airplanes with liquid explosives. The attackers planned to disguise the explosives as ordinary liquids and smuggle them aboard. For this reason, authorities in both the United States and Great Britain warned all passengers that liquids would not be allowed in carry-on luggage until the crisis passed. The ban on liquids included hair spray, shampoo and beverages — items people travel with all the time.

So what exactly are liquid explosives, and what do they do? Most explosives work in basically the same way. They burn or decompose very quickly, producing lots of heat and gas, which rapidly expands and can tear things apart. Usually, an explosive material requires some kind of stimulus, like heat or shock energy, to get the process started. You can learn more about different types of explosives in How Bombs Work.

Many people don’t think of explosives as liquids, though. Most of us imagine them as solids, like gunpowder or C-4. But you’ve probably heard of one liquid explosive already — nitroglycerin. Nitroglycerin was invented in 1847, and it’s made by adding acids to glycerin. Since exposure to it dilates people’s blood vessels, it’s used as a medical treatment for angina pectoris, or heart pain.

With the popularity of AJAX growing every day I’ve had the opportunity to collect and try out many more tutorials in the last several months. These examples and how-to’s represent the best tutorials that I’ve personally used or otherwise had the opportunity to work with out of the overall group. This post is intended for individuals who learn best by example. Most of the listed tutorials come complete with instructions and source code. I’ve also categorized all of the tutorials for easy browsing. Enjoy!

When you get to hang out with other experienced computer professionals you start to realize how many things you do not know. I have been working with Windows since 3.0 came out, and I still find something new all of the time. For example, I was sitting behind one of my tech friends and he was using alt-esc to tab through windows in the order they were opened - I never even knew this existed. I set out to get a comprehensive list of all the shortcuts. Here is what I have found so far:

An 1949 Popular Science article from gives instructions to make laughing gas. You may have seen a censored version of this on a recent episode of the Mythbusters. The site is incredibly slow right now, so I have mirrored the pages below for your viewing pleasure.

If you’ve wanted to start programming, Python is a rather popular and easy language to learn and use. hose of you who remember when BASIC was king, Python is similar to an updated and more powerful version of BASIC, and there’s many similiarities between the two. (It also happens to be named after British comedians!) For the most part, Python is an interpreted language, meaning that you have to have the Python interpreter to run any Python programs. As a rule of thumb, if a computer can run the Python interpreter, it can run most Python programs. There’s Windows, DOS, Windows CE, Mac, Linux (Check your distribution’s package manager), Java, and many other interesting versions officially avaliable.

There’s also many good Python tutorials avaliable, such as Dive Into Python (for people with prior programming experience), and, for those new to programming or with less experience, The Non-Programmer’s Guide to Python. Happy coding, everyone!

Black Hat Multimedia - Presentation, Audio and Video Archives

This archive of computer security presentations is provided free of charge as a service to the world wide computer security community.

Speaker presentations and materials are put on-line generally two weeks after the event. Audio and video are generally available 6-9 months after the conference. If a speaker is listed on the conference page, but their speech is not present here it generally means there is no available audio, video or materials.

If you are interested in learning about security topics, I Highly suggest checking out a lot of these presentations.  There is some GREAT information contained.  Oh, yeah I do realize that they use Real Player (Seriously?)  instead of using the Real Crap player, get RealAlternative.
