Hey readers! This tutorial will be the entry point for the introduction of buffer overflows. Something like requesting user input is a very common place for vulnerabilities to pop up and we will definitely have fun while trying to make programs crash. But for now, let's start with how we can get input from a user.
There are few kitchen tools as elusive as the oyster knife. Many people—even seafood lovers—don't own one. If you do own one, it probably gets used so infrequently that it gets sent to the very back of the shelf where it proceeds to get lost. Then you accidentally find the knife once a month when you don't need it, but can't for the life of you find the sneaky little thing when you do need it.
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...
Animal masks are always a popular option for Halloween, not just because you can pair them with practically any outfit, but because they never go out of date. They've been a staple of Halloween costumes starting from the 1900's, but possibly even prior to that. George Takei, of Star Trek popularity, even left a hilarious comment on Accoutrements' Horse Head Mask Amazon page, making puns left and right about the animal mask—a testament to how trendy these faux mammalian skins really are.
I love cheap, nutritious food: lentils, rice, toor dal, and other beans and grains. Even popcorn. The only problem is that they usually come in floppy plastic bags that make measuring ingredients more difficult. I usually open up one corner of the bag only to have everything come spilling out all at once whenever I try to pour out measured amounts.
Parents, grandparents, aunts and uncles, and even older siblings have all likely dealt with handing their smartphones over to young children. No matter if they want to play games or watch cartoons or record funny noises, you're handing over a very personal device to those who can mess up what they don't know.
As you may have already heard, the worst bug in OpenSSL history went public yesterday, dubbed Heartbleed. While we can go deeper into the technical details of it later, the short version is that OpenSSL, the library used to encrypt much of the web running on Linux and Apache has been vulnerable for up to two years.
Welcome back, my budding hackers! I've written several listener guides on creating a malicious PDF or malicious Word document that would carry in it a payload with the Meterpreter, or reverse shell enabling you to own the system. One of the hurdles to using these techniques is the antivirus (AV) software on the target system. For instance, if you try to email a malicious PDF or Word doc, it's likely that the victim system will alert the victim that it contains a virus or other malware.
Even if you have the fastest internet connection in the world, it's not going to be fast if your Android device isn't optimized to use all of the bandwidth. I have pretty fast speeds at home, but every now and then my web surfing on my Nexus 7 tablet is halted in its tracks—for seemingly no reason.
A lot of people have problems with their cats urinating inside the house, leaving behind the retched odor of cat pee. Others get frustrated when feral or stray cats pee on their porch, patio, or anywhere else outside of their house, as it's not the most welcoming odor when guests arrive.
What's the meaning of life? That's the age-old question; but can it ever really be answered? I mean, isn't life just a big game anyway? Perhaps, a game of inches?
Sometimes you just want to grill. It doesn't matter where you are, what you have, or whom you're with—you just want a delicious burger and you don't care what it takes.
Camping is wonderful isn't it? You get to go out into the wild, build a fire, pitch a tent, and tell ghost stories. My favorite part about camping isn't any of those things, though. No, the best part about camping in my opinion is the food. Whether it be planking freshly caught fish, roasting hot dogs, melting s'mores, or cooking hobo dinners, the food is always the most memorable part of camping to me because you get to eat stuff outside of the norm.
There’s a good chance that you’ll be alone in life one day, and no... I’m not talking about a couch-bound, dateless loser with a pocket pussy and a bag of potato chips. I’m talking about alone. In the wilderness. Hungry. Cold. Lost. You can’t stay in one place too long, so it would be nice to have something to carry your belongings in. Maybe it’s post-apocalyptic land where you’re the sole survivor, and all the backpacks and rucksacks in the world are but mere ash. Either way, knowing this si...

Greetings all. Before I get into the tutorial, I would like to mention that I am fairly new to Null Byte (been lurking for some time though), and what really appeals to me about this place is its tight, family-like community where everyone is always willing to help each other and the constant search for knowledge that inhabits this subdomain is a driving motivator for me to join in. I'm glad I arrived at the right time. Anyway, wipes tears (not really)...

Now, our goal is to take this a step further and get an interactive shell. To do this, we need to upload another file that either binds a port for us, or connects back. For this tutorial, we will use a Python reverse Meterpreter shell.

Free trials are a great way to test out products before a purchase, or simply for the exploitation of free stuff for that limited amount of time. Some trials last a few days and some last even a month or two, but no matter what—these trials will always expire. But like most things in life, there is a way to get around such limitations.
