Many of our members here at Null Byte are aspiring hackers looking to gain skills and credentials to enter the most-valued profession of the 21st century. Hackers are being hired by IT security firms, antivirus developers, national military and espionage organizations, private detectives, and many other organizations.
Hello null_byters, after some time out here we are again with another tutorial, continuing our beautiful series, today we will write our first real world bash script.
If you haven't read the last article, feel free to stop by and give it a read, but abstaining from reading it will not, for the most part, be detrimental to your understanding.
Update (February 2019): The methods below will help on older Android versions, but we've recently revisited this topic. So if you have a newer Android phone and you want to get rid of Google, head here.
It's been a while when the major web browsers first introduced HTTP Strict Transport Security, which made it more difficult to carry Man In The Middle (MITM) attacks (except IE, as always, which will support HSTS since Windows 10, surprised?).
To say we're a nation of coffee-lovers is putting it mildly. Americans consume 400 million cups of joe in one day alone, but how well do we actually know our morning BFF? We know it comes from a bean, and that more coffee drinks exist than there are ways to skin a pig, but what else?
Heartbleed, move over. There's a new bug in town, and this time it's also affecting Mac and Linux computers. It's called Shellshock (its original official title is CVE-2014-6271), and it's currently got a 10 out of 10 severity rating over at the National Cyber Awareness System. While some updates have been issued to fix this bug, they were incomplete, and your system is probably still vulnerable, as it has been for the last probably 20 years.
French toast is one of those things that everybody kind of knows how to make, but few people know how to do really well. And while the dish originally does hail from France (its original name, pain perdu, means lost or wasted bread), it has become a beloved American breakfast dish.
If you've been to a farmer's market during tomato season, chances are you know that heirloom tomatoes are pricier (and funnier-looking) than their hybrid counterparts.
Welcome back, my hacker apprentices! Last week, I started off my password cracking series with an introduction on the principles and technologies involved in the art of cracking passwords. In past guides, I showed some specific tools and techniques for cracking Windows, online, Wi-Fi, Linux, and even SNMP passwords. This series is intended to help you hone your skills in each of these areas and expand into some, as yet, untouched areas.
For the novice cook, fungi can be weird because, well, they're fungi. However, if you've been afraid to get acquainted with mushrooms, you've been missing out. Vegetarians love mushrooms and with good reason.
Brining is magic. All you have to do is make a mild saline solution, toss in your protein of choice, let it soak, and cook. You end up with incredibly tender, flavorful meat or tofu for very little effort. So why aren't more of us doing it?
It has been a long while since I last came here to write an article. Graduate school keeps you busy. After I looked over what I had written previously, I decided that I should introduce another fun topic from cryptography. In this case, steganography.
Apple released the new Mac OS X 10.10 Yosemite in the Mac App Store for everyone to download and install for free on October 16th, 2014, but downloading a 5+ GB file for each of your computers will take some serious time. The best thing to do is download it once and create a bootable install USB drive from the file for all of your Macs.
Update: June 19, 2014 Android 4.4.4 has been released, fixing a small security bug in 4.4.3. The factory images have already been made available to all current-generation Nexus devices, and I've linked them out below. This does not affect the process depicted, you can still use these same steps to bring your device up to date with this latest release.
I grew up in a household where bacon was considered its own necessary food group. My mom saved the bacon fat in a jar and reused it in other dishes, which my friends considered vile, unless they were also from immigrant families or the American South, where saving bacon fat has never gone out of style.
One of the biggest problems in data security is authentication of data and its source. How can Alice be certain that the executable in her inbox is from the venerable Bob, and not from the not-so-venerable Oscar? Clearly Alice wants to know because if this file is actually sent to her by Oscar, the file might not be a game, but a trojan that can do anything on her computer such as sift through her email and passwords, upload her honeymoon pictures, or even turn on microphones and webcams. Thi...
While most people were worried about having the scariest costume when I was younger, I was always more interested in the candy. While everyone wasted time trying to perfect their costume, I was busy mapping out every detail in my city, finding the most efficient way of getting the most candy in my pillowcase(s) before the night ended. Although I'm long retired from the game, it's about time to pass along all of the tips and tricks I've learned from my youth for getting treats. So, here I pres...
With warm weather comes bugs, and with bugs come bites, and with bites come itches. From ticks and spiders to mosquitoes and bees, insect bites come in sundry shapes and sizes, but they all commonly pull an itchy, red reaction out of our bodies.
Living in Los Angeles has given me the opportunity to attend a bunch of really cool events. I've been to Dodgers, Lakers, and Clippers games, a few concerts at the Staples Center, and a plethora of smaller joints.
Thought I would cross-post a piece I did a while ago.
If you read my article on the OSI model, you got a good overview on communications from that model's perspective, but how does that relate to TCP/IP? We're going to take it a step further, getting into the idea behind the two address concept. How does an IP address and a MAC address work together? If you want to hijack sessions and all sorts of lulz like that, you need to understand these concepts. Let's get into it, mates!
SCRABBLE. To some it's just a game, but to me it's life or death. Well, not really, but it feels that way anyway. On a normal weekend, a game becomes much like Jon Thomas' "friendly game of death Scrabble."
As the best-selling toy of all time, the odds of you once playing with a Rubik's Cube are pretty high. And if you're like me, or even the cube's inventor Erno Rubik, your first attempts likely ended in futility. Every twist, every turn, the cube just gets more and more mixed up. Is there really a solution?
Apple announced support for mobile driver's licenses and state identification cards in Apple Wallet back in 2021, and Arizona was the first state to jump on board in 2022. Fast forward to now, and only eight states let you add a driver's license or state ID to Apple Wallet on your iPhone and Apple Watch. It has been a slow rollout, but more states are coming or are at least showing interest.
The Reminders app is a simple yet powerful task manager, and it does a great job of reminding you to start an errand, alerting you to a project that's supposed to be done, or prompting you about a recurring chore. But with the latest Reminders update, the dates and times you set for tasks can act more like due dates thanks to the new early reminders feature.
The Calculator app is probably one of Apple's most-used iPhone apps, yet I always meet people who don't know all the little tricks there are to using it more efficiently. You may know most of them, but there's a chance you don't or at least forget about some of them.
Apple's next big iOS update is ready for your iPhone, and it's out just a little bit more than a month after the iOS 15.0 update was released — and 14 days after iOS 15.0.2. The hottest feature you'll find in iOS 15.1 is definitely SharePlay, but what else is hiding within Oct. 25's new firmware?
One of the best recent outings in the Marvel universe is the animated series What If...?, which explores alternate universe takes on various superhero storylines that deliver fascinating scenarios if one single factor had been different in the story.
As the U.S. inches closer to herd immunity and reopening after the pandemic, it may become necessary to keep your COVID-19 vaccination cards on you at all times to gain access to places and events that are prone to spreading the coronavirus. You probably won't want to lose your card, so it may be wise to load a copy onto your smartphone for easy access.
Never being contacted for a job you're interested in interviewing for is a terrible feeling. It might make you feel inadequate as if your qualifications aren't up to par, but the problem might be that your resume isn't even getting read in the first place.
When it comes to augmented reality wearables, it's currently an enterprise world. As such, Magic Leap's latest Lumin updates are centered on features that appeal to enterprise customers. And Epson and Spinar are joining forces with a solution for distributed workforces.
Since iOS 11, a thumbnail preview appears on your iPhone whenever you take a screenshot. It's useful for access to quick sharing options and editing tools, but you can't disable the preview image. You can wait for it to disappear or swipe it off-screen, but that's as good as it gets — until now. In an iOS 14 update, there's an option to disable the screenshot preview — only you won't find it in Settings.
As a means to combat annoying and intrusive advertisements in Safari, Apple added native support for content blockers on the iPhone. Instead of being bombarded by notifications, banners, and pop-ups, content blockers prevent them from opening, which can also be said about those annoying cookie consent notices that many websites now have.
In response to Sony unveiling its own holographic display back in October, Looking Glass Factory CEO Shawn Frayne quickly penned a letter welcoming the electronics mainstay to the field, with a post-script teasing the reveal of their own for December of 2020.
Quietly, while the rest of the world was engaged in pandemic and political concerns, a few weeks ago Facebook casually upgraded its Spark AR platform with what it calls Unified Effect Publishing.
At the beginning of every year, Samsung drops a fantastic phone in the Galaxy S series, and then tries to top it with the Galaxy Note series in August. This year, Samsung had their work cut out for them. But they managed to improve on their predecessor and properly challenge Apple's best.
Automation has been a buzz word for quite some time now, but the principles behind it are as strong as ever. For a hacker or pentester, Bash scripting is one form of automation that cannot be ignored. Virtually any command that can be run from the terminal can be scripted — and should be, in many cases — to save valuable time and effort. And a Bash script just happens to be great for recon.
Everything you post on social media lives there forever — even if you delete it. Just ask anyone that's ever posted something stupid. Instagram does not provide built-in tools to save or download images and videos from other users, but there are workarounds. Third-party tools make saving other people's photos and videos easy, and there are always screenshots.
A modern iPhone is capable of running sophisticated, exquisitely-rendered games that rival titles on current-generation consoles. However, there is some value in classic video game titles, whether you grew up playing games on the Atari 2600, Nintendo Entertainment System, and Sega Genesis or not.
