Welcome finally, to a tutorial on buffer overflows! At last we have reached an exciting part of this series where I will dedicate the entire article on explaining and exploiting the notorious vulnerability. Grab some popcorn, sit back and enjoy the show.
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.
It always looks different when it's not about you. The Internet is our world's Alterego. Those many bits don't really make sense unless we want them to be valuable, to mean something.
In case you didn't know, Android has an awesome hidden settings menu called "Developer options" that contains a lot of advanced and unique features. If you've ever come across this menu before, chances are you just dipped in for a minute so that you could enable USB debugging and use ADB features.
One of Android's biggest strengths, when compared to other mobile operating systems is its open file structure. Google introduced a built-in file manager with Marshmallow that provides basic file management, but like with most apps on Android, there are alternatives. Third-party file managers are readily available, providing deeper access and control of all your files.
The release of iOS version 8.1.1 brought some much needed bug fixes to Apple's mobile operating system, but with it came a patch for Pangu's jailbreak method, which worked on iOS 8.0 to iOS 8.1 using a Mac or Windows computer. Luckily, it didn't take very long for a new team of developers to come up with a method for jailbreaking iOS 8.1.1 devices, and much like its predecessor, the process is a cinch.
Probably SSH is not as clean and fast as other useful tools like netcat, but it has some features which are very useful, and when you'll need them, here's how to behave with that huge amount of computers all over your house.
I am an English major physically allergic to all algebraic formulas, so you're unlikely to get any help from me when it comes to solving any expressions. But in the glorious technological age we live in, there are plenty of apps that actually make math and problem solving fun, even a little bit addictive.
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.
Jailbreaking gives you root access to the iOS file system, allowing you to install third-party apps and tweaks on your iPhone that aren't available in the App Store. It opens up a whole new realm for what your device can do, but it can also cause instability across the system and can dissuade you from getting future updates from Apple that have important features, bug fixes, and security enhancements.
Welcome back, my hacker apprentices! Metasploit framework is an incredible hacking and pentesting tool that every hacker worth their salt should be conversant and capable on.
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...
There are many impressive features on a Samsung Galaxy Note 2, but just like any other smartphone on the market, the most used one is the camera. How many times did you take a picture today? Or admire all the selfies in your gallery? Or upload a video to Instagram, Vine, or Snapchat?
The best part about April Fool's Day is that everyone is fair game. Even big tech companies like Google and Twitter get in on the action every year. It encourages even the most uptight, unfunny party-poopers among us to have a little fun driving each other crazy with pranks — even at work.
It's a controversial headline, I know, but bear with me and I'll explain in due course. Disclaimer: I was once a child, and I played lots of video games. I didn't look anything like this child.
All kinds of people pretend to be someone they're not on the internet, including scammers, people attempting to wind others up, hackers and web predators. Almost all of these people will leave bases uncovered and they're all easy to expose when you understand how to. Here are my favorite ways of finding out when somebody is lying quickly. Image Search
To some, SCRABBLE is just a board game to play during family game night or during a casual get-together. Others think of SCRABBLE as a mere hobby. But with any activity, there will always be fanatics—the ones who would rather sell their soul than stop—the ones with a constant yearning for self-improvement—the merciless.
If you're an AirPods user, things are a lot better with iOS 18 and iPadOS 18. If you're not, it may finally be time to grab yourself a set of AirPods, especially if you're into privacy and gaming.
You no longer have to worry about repair technicians accessing the personal information on your iPhone when you send it in for repairs. With Apple's new security feature, you'll no longer have to erase your iPhone to ensure your photos, messages, accounts, and other private data remain for your eyes only.
Safari isn't the only web browser on your iPhone or iPad that will let you add icons to your Home Screen for progressive web apps and website bookmarks. Apple gave developers the key to its "Add to Home Screen" feature, and your favorite iOS or iPadOS web browser may already support it.
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.
Now that Bard — Google's response to the revolutionary ChatGPT generative AI chatbot — is out in the wild, it's beginning to let its freak flag fly.
Ringtones and text tones can be annoying, so my iPhone is almost always set to vibrate on silent mode. Unfortunately, that causes me to miss phone calls and text messages when the device isn't in my hands or pockets. While I hate missing alerts, I'm still reluctant to switch to ring mode — and that's where another iOS and iPadOS feature helps out.
Apple automatically converts most URLs in the Messages app into rich link previews, but they aren't always pretty, and sometimes you just want to see the full URL instead. While there is no setting on iOS, iPadOS, or macOS that disables rich link previews in the Messages app, there is an easy way to show the URL complete with the scheme, domain name, and path.
Remember when water and iPhones couldn't mix? Pools, tubs, and toilets would suck down the working iPhones of clumsy and careless owners and spit out expensive paperweights like they were nothing. Times have changed, however, and the newest iPhones can take a swim without fear of certain death. But a dip in liquid can still cause muffled music and audio from the speakers.
While you can quickly see the edit history of a modified iMessage in the Messages app, there's no way to view an iMessage that somebody in the conversation deleted unless you happened to see it before it disappeared. But that's only true if you didn't implement these security measures on your iPhone.
You see it in the movies all the time. A character on the phone doesn't like what the other person is saying or telling them to do, or they just don't want to talk to them anymore, so they fake bad reception and cut the call off. In real life, it's pretty easy to tell when someone is doing it, and there are better ways to end a call abruptly so that it looks like you didn't hang up on them.
There has been drag-and-drop functionality for iPhone since at least iOS 11, but iOS 15 adds a new ability that makes essential emails even easier to find when you need them.
The Lens Studio community, now made up of more than 200,000 creators, has generated some impressive augmented reality effects in the last few years. Amazingly, the groundbreaking Lenses for Snapchat continue to come, often from the internal AR team at Snap.
It's already been a banner year for mergers and acquisitions in the augmented reality industry, with WaveOptics and Ubiquity6 among the notable companies acquired. Two of the more active M&A players, Snap and Epic Games, continued their respective buying sprees this week with major deals supporting their AR strategies.
There's already some fierce competition between Snap and Facebook in the AR space, but it's about to heat up even more, with Snap snatching up a 3D mapping startup that could add some new AR capabilities to its arsenal.
The Metaverse, or AR cloud, has been a sci-fi dream for decades, but only recently have companies begun to actually develop the technology to build it. With its latest funding round, Epic Games is suddenly a front-runner in this pursuit.
Apple's stock keyboard for iPhone has gone through many changes over the years. Some have been significant, and others more subtle. Overall, most of these updates have been fairly obvious, so you're probably already using them — but there are more than a few interesting features that were slipped in under the radar that you may not know about.
The battery on your iPhone can go from 10% to completely dead in a matter of minutes, or at least it can feel that way. Apple does prepare you with an alert when you hit the 20% and 10% mark, but it's easy to forget to charge your iPhone before it dies even with those notifications. That's why you should also be notified when your battery's down to 5% remaining.
While Touch ID has been a part of the iPhone's legacy since 2013, Apple waited until 2016 to add biometrics to its MacBook lineup, and it's not as impressive. An iPhone with Touch ID can register up to five fingerprints, but Macs can only register a maximum of three per account. If that seems unfair, there's an easy trick to doubling that number, meaning six of your fingerprints could unlock your laptop!
Google released the first build of Android 12 almost exactly one year after dropping Android 11, which is remarkable in the midst of a global pandemic. But you can tell the Android engineers have been hard at work while quarantining, because the latest OS version is absolutely packed with new features.
TikTok has grown to be one of the most popular social media platforms in the world. The video-sharing app is a driving force for viral content, spurring various popular movements in dance, pranks, comedy, and more. And as one might assume, videos on TikTok don't stay on TikTok — they're shared on Instagram, Twitter, and other services where millions of people get the chance to also view them.
Bash scripting is a convenient way to automate things on any Linux system, and we're going to use it here to automate certain tasks we use all the time.
Apple released the first public beta for iOS 14.5 on Thursday, Feb. 4. This update is proving to be the most significant in some time, offering new features and changes like support for PS5 DualSense and Xbox Series X controllers, the ability to unlock your iPhone using your Apple Watch, AirPlay 2 support for Fitness+, Reminders sorting and printing options, 5G support when using dual-SIM, and more.
