Hack Like a Pro: Abusing DNS for Reconnaissance

Welcome back, my tenderfoot hackers! As you know, DNS, or Domain Name System, is critical to the operation of the Internet.

News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

News: Why Is Linux & Other Open-Source Software Free?

Welcome back, my greenhorn hackers! As hackers, we often take for granted that nearly all of our hacking tools and operating system are free and open source. I think it's important to examine a bit of background on how we arrived at this intriguing juncture in the history of computer software. After all, we pay for nearly all of our other software (Microsoft, Adobe, etc.) and nearly everything else we use in life, so how is it that Linux and all our hacking tools are free?
