Cellular carriers like to nickel-and-dime us out of every bit of money they can feasibly justify, so as consumers, we owe it to ourselves to make sure that we're getting our money's worth.
Welcome back, my tenderfoot hackers! One key area on the minds of all hackers is how to evade security devices such as an intrusion detection system (IDS) or antivirus (AV) software. This is not an issue if you create your own zero-day exploit, or capture someone else's zero-day. However, if you are using someone else's exploit or payload, such as one from Metasploit or Exploit-DB, the security devices are likely to detect it and spoil all your fun.
Welcome back, my tenderfoot hackers! Web apps are often the best vector to an organization's server/database, an entry point to their entire internal network. By definition, the web app is designed to take an input from the user and send that input back to the server or database. In this way, the attacker can send their malicious input back to the servers and network if the web app is not properly secured.
To serve as a framework for the "Nexus Imprint" feature in their new Nexus 5X and Nexus 6P smartphones, Google added native fingerprint scanner support to Android 6.0. Sure, Android devices have had fingerprint scanners in the past, but this is a unified, system-wide implementation that all devices can use—meaning that in the near future, we may finally start to see apps that let you log in to your account with your fingerprint instead of a password.
With Touch ID on iOS devices, it's a little more difficult to lock yourself out. However, it can still happen if you don't use it, have a busted fingerprint scanner, or use an older device that doesn't have Touch ID, which means you're passcode dependent (unless you have zero lock screen security).
Hey there, reader! In this tutorial we are going to explain how values are stored in variables as either signed or unsigned. Try to not get lost!
When you have some form of lock screen security enabled, Android makes sure that you don't have to fumble around to enter your pattern, PIN, or password before you can call 911 in an emergency. It does this by adding an "Emergency Call" button to the bottom of the screen—but as handy as this may sound, most of the time it's more trouble than it's worth.
INTRODUCTION Hello dear null_byters here we go again with our third part of this serie.
In general, the fingerprint scanner in Samsung's 2015 flagship phones is quick and accurate, but when you get that "No Match" message while trying to unlock your phone, it can be incredibly annoying. To help curb these issues, I'll go over three tips for speeding up the unlocking process that should work wonders on your Galaxy S6, S6 Edge, S6 Edge+, or Note 5.
I see many people posting the same thing on the internet. "How do I become a hacker? Where do I commence?"
Every time Windows gets a significant update, the vast majority of existing tweaking utilities become obsolete. For every option that you fine-tuned with one of these tools on Windows 7 or 8, there's a change in the registry or system settings that cause your tweaks to now point to a dead end. This was definitely the case with Windows 10, since there were so many sweeping changes that very few existing options carried over.
Although I know it will never happen due to Apple and Google's tempestuous relationship, I sometimes wish I could cast iTunes or Apple Music from my Mac to Google's Chromecast. When you don't have speakers to blast your music, the television is a great alternative to amplify your music.
Keyboard shortcuts can make using your Mac faster and easier, and leave your mouse feeling archaic. With just a few taps, you can save files, open new tabs, or play a movie—all without using your mouse even once.
When it comes to security, there are usually only a handful of things that you want protected from prying eyes on your iPhone—private photos, scandalous videos, and important text, such as credit card and social security numbers.
Hi all, Pro Hackers/Crackers, Let's see how we can use batch for our own Protection instead of exploiting someone with it.
Samsung has a long-standing reputation for packing their devices with lots of added functionality, and the Galaxy S6 Edge is no exception. It comes with a nifty feature called "Information stream," which allows you to get quick, at-a-glance information by swiping the edge of your screen back and forth while the display is off.
If you are anything like me, you have a knack for taking silly selfies of yourself, i.e., taking scotch tape and wrapping it around your face to make yourself look like the blob, or perhaps you like taking selfies of yourself in weird or unusual situations doing weird and unusual things.
Although this century is still young, with little fanfare we may have just witnessed the "Hack of the Century." AV software developer Kaspersky of Russia recently announced that they found that some hackers have stolen over $1 billion from banks around the world!
While you may not have loads of secret files hiding on your computer, there might be one or two items that need a little extra security, like a file of website logins or a folder of risqué photos.
Welcome back, my hacker novitiates! Eluding and evading antivirus software and intrusion detection systems is one of the most critical tasks of the hacker. As soon as a new exploit is developed and discovered, the AV and IDS developers build a signature for the attack, which is then likely to be detected and prevented.
As far as wallets go, mine is as full as they come; think something like George Castanza's overstuffed wallet on Seinfeld. I've got receipts, pictures, and tickets jammed inside, but what takes up the bulk of the space are all of the cards—credit, debit, gift, rewards, customer loyalty... I've got pretty much any card you can think of squeezed in. While it is a strain on my rear end, there's nothing I can do besides keep some of the cards elsewhere. However, looking for them when I need them ...
Welcome back, my tenderfoot hackers! Those of you who have been reading my posts here for awhile know how much I emphasize good reconnaissance. Novice hackers often jump into a hack/exploit without doing proper recon and either fail or get caught. Experienced and expert hackers know that 70-80 percent of a good and successful hack is dependent upon successful and accurate reconnaissance.
Welcome back, my greenhorn hackers! Before we attempt to exploit any target, it is wise to do proper reconnaissance. Without doing reconnaissance, you will likely be wasting your time and energy as well as risking your freedom. In previous guides, I have demonstrated multiple ways to perform reconnaissance including passive recon with Netcraft, active recon with Nmap or hping3, recon by exploiting DNS or SNMP, and many others.
On mobile devices, the Notification Center received a huge facelift when iOS 8 was released, but it wasn't until Yosemite that its Mac OS X counterpart received the same amount of love—especially the much needed ability to add custom widgets, like a FaceTime dialer.
Coffee shops are a relaxing place to get work done on your laptop; there's free Wi-Fi, fresh coffee, and people generally leave you alone. Inevitably, those cups of coffee will go straight through you, resulting in a much-needed bathroom break. But while you're attending to your bodily functions, who's attending to your MacBook?
One of the biggest improvements in Mac OS X Yosemite came to the Spotlight search feature, allowing users to not only search through their applications, but also their emails, text messages, iCloud, and the web.
Apple has a built-in way to protect you from opening up potentially malicious apps on your computer in Mac OS X Lion, Mountain Lion, Mavericks, Yosemite, El Capitan, and macOS Sierra. This setting, named Gatekeeper, will never stop you from installing apps from the Mac App Store, but it could from anywhere else. If it's an app you're sure you want to install on your system, here's how to do it.
Welcome back, my novice hackers! New hackers often ask me the same question: "What is the easiest platform to hack?" My response is always the same—it is not a platform, but rather a particular piece of software that is easiest to hack, which is on nearly every client-side system. That software is Adobe Flash Player.
Welcome back, my hacker novitiates! Every so often, a MAJOR vulnerability appears that makes millions of systems vulnerable to attack. The most recent, named Shellshock, basically leaves every Mac OS X, Linux, and UNIX system on the planet vulnerable. As nearly two-thirds of all web servers on planet Earth run one of these operating systems (primarily Linux), that's a whole lot of systems out there waiting to be harvested.
Welcome back, my amateur hackers! Many of you here are new to hacking. If so, I strongly recommend that each of you set up a "laboratory" to practice your hacks. Just like any discipline, you need to practice, practice, and practice some more before you take it out to the real world.
We live in a time where privacy is rare and our files can be easily accessed by just about anyone. Having your phone protected by a passcode is great, but if someone figures it out, they can easily access anything on your phone.
Most times when you take your smartphone out of your bag, pocket, or purse, you probably know exactly what you're going to do with it. Make a call, send a text, take a selfie, browse viral videos on YouTube, or one of the other many things a smartphone can do nowadays.
Security is a priority for many when they first set up their mobile devices. Nobody wants to have a stranger or nosey friend go through their phone and discover risqué photos or embarrassing text messages. These days, the closet is gone—everyone keeps their skeletons in their phones.
Welcome back, my novice hackers! In a recent tutorial, I showed you how to use shikata_ga_nai to change the signature of a payload to evade detection by security devices (firewalls, IDS, etc.) and AV software.
The book that started it all (published in 1967). When Virginia Harvey wrote this book, she remarked that macramé was almost a lost art...
Welcome back, my rookie hackers! Most often, the professional hacker is seeking protected information from the target system or network. This might be credit card numbers, personally identifiable information, or intellectual property (formulas, plans, blueprints, designs, etc.). Most of my Null Byte guides have been focused on getting into the system, but this only begs the question—"what do I do when I get there?"
LG's arsenal of screen-off and screen-on tap gestures recently expanded into lock screen territory. Dubbed "Knock Code", this feature allows owners of various LG phones, like the G2 and upcoming G3 to unlock their phone with a series of taps on the screen. The most impressive part is that the screen doesn't even need to be on!
It started in Australia, and now seems to have made its way statewide—hackers are remotely locking iOS and Mac devices, holding them for a $100 ransom. Users awoke to the loud "lost iPhone" ringtone, with a message on their lock screen stating that "Oleg Pliss" has hacked their device, and that "they" will unlock it after being sent $100 through PayPal.
Once you unlock your bootloader and root, you're left with one more hurdle to overcome, and that's getting S-Off.
A few days ago I finally finished my 2 week journey into trying to get OpenVas to work properly. You all may have noticed that you can't just click the setup openvas in kali and have it working properly.
