How To: Use Meterpeter on OS X

Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on OS X (it has several more commands/options), but I think it is still worth noting how to do it. I've even seen some people mistakenly say that Meterpreter can only be run on Windows, which is not true. Meterpreter can ea...

News: What the Heck Was Stuxnet!?

As many of you know, I firmly believe that hacking is THE skill of the future. Although the term "hacking" often conjures up the image of a pimple-faced script kiddie in their mother's basement transfixed by a computer screen, the modern image of the hacker in 2015 is that of a professional in a modern, well-lit office, hacking and attempting to development exploits for national security purposes. As the world becomes more and more digitally-dependent and controlled, those that can find their...

How To: Monitor System Usage Stats in Your Mac OS X Menu Bar

Like a car, your Mac needs to be monitored and cared for to keep it running as smoothly as possible. While your vehicle comes with a ton of gauges to keep track of your oil, temperature, and in some cases, even tire pressure, your Mac has no easy way to watch for low memory or high disk usage. Normally you would have to open up Activity Monitor to take a look at your usage stats, but now there is something better.

How To: Upgrade to Mountain Lion from Leopard (OS X 10.5 to 10.8)

Mountain Lion (OS X 10.8) is out today, available in the Mac App Store for just $20. Unfortunately, installing Mountain Lion requires that you already have a Mac running Snow Leopard (OS X 10.6) or Lion (OS X 10.7). If you're currently running a Leopard system, you're out of luck, and need to pay $29 to upgrade to Snow Leopard, and then an additional $20 to upgrade again to Mountain Lion. That sounds like way to much trouble to me. But why exactly is Leopard incompatible? Turns out it's not—m...
