Attacks against databases have become one of the most popular and lucrative activities for hackers recently. New data breaches seem to be popping up every week, but even with all of that attention, databases continue to be a prime target. All of these attacks have to start somewhere, and we'll be exploring a variety of methods to gather information on PostgreSQL databases with Metasploit.
If you have a OnePlus phone with an in-display fingerprint scanner like the 6T or 7 Pro, the "Quick launch" feature can put a variety of app shortcuts right on your lock screen for easy access. For example, you could use the "My apps" shortcut for the Play Store to check for your app updates in an instant.
Boomerangs are perhaps the quintessential story tool on Instagram. Surprisingly, there's never been much to them — point and shoot, and your subject plays forward and backward in a never-ending loop. Perhaps its prolonged simplicity inspired Instagram to give Boomerangs a bit more depth because the company just introduced three new effects to try out.
Google is an incredibly useful database of indexed websites, but querying Google doesn't search for what you type literally. The algorithms behind Google's searches can lead to a lot of irrelevant results. Still, with the right operators, we can be more exact while searching for information that's time-sensitive or difficult to find.
From the first moments of booting up Harry Potter: Wizards Unite to the hours of walking you're bound to experience, one thing is clear — encountering Foundables and defeating their Confoundables is a significant plot point of the AR game. While you receive rewards each time you retrieve a Foundable, the real treasure comes from completing parts of the Registry, called "Families."
I don't know about you, but I like to listen to music throughout the day. As I am writing articles or doing some cardio at the gym, I go through my playlist, only stopping the music in situations where I have to. And ever since I switched to the Samsung Galaxy S10+, this has gotten even easier to do.
Information gathering is one of the most important steps in pentesting or hacking, and it can often be more rewarding to run things on the target itself as opposed to just running scripts against it remotely. With an SQL injection, a hacker can compromise a server and, ultimately, upload and run the "unix-privesc-check" script locally in order to further identify possible attack vectors.
Last year at CES, RealMax blew away the AR headset competition with a prototype AR headset surpassing 100 degrees field of view.
Cross-site scripting can be one of the easiest vulnerabilities to discover, but to be successful with this type of attack, it is essential to learn how to get past filters. In the previous guide, we explored some ways to do this, such as abusing attributes and event handlers and tricking the application into accepting unusual characters. Now, let's take a look at more techniques used to defeat filters.
One option you won't find buried in the Galaxy Note 9's Settings is the ability to return the navigation bar to black. Samsung changed the default color to white with the Note 8, removing any ability to bring the black color back. But thanks to a neat app, Note 9 users can do it themselves.
Earlier this month, when Apple announced at WWDC that iOS 12 would include an augmented reality tape measure called Measure, iPhone watchers seemed impressed by the new addition to the company's AR arsenal. Well, just a couple of weeks later, on June 19, it appears that Google remembered it had its own Measure app as well.
Action Launcher has some exclusive features that add real value to your overall experience. One such feature is Shutters, and like with most aspects of Android, there's a workaround that will let you enjoy this functionality on other launchers.
Less than a week after iOS 11.3 was released to the public, iOS 11.4 beta dropped for developers on April 2, then became available for public beta testers the following day. If you're an iPhone user, there doesn't seem to be much to love about iOS 11.4 just yet, since its mostly geared toward education uses for iPads, but Messages on iCloud is back, as well as AirPlay 2.
Smartphones are like high tech buckets that collect our personal information through constant use. This has some obvious benefits, like getting a more personalized experience with our devices. On the other hand, this data is a tempting target for bad actors looking to make a buck at the expense of your privacy.
After receiving many requests for the feature, Signal introduced read receipts last year to its mobile apps. However, some users don't like the idea other people knowing when they've read messages. Luckily, Signal lets you disable this feature and reclaim a little privacy.
Over the years, Nova Launcher has widened its audience. No longer is it simply a tool to return your home screen to a more stock look. With Nova, you gain customization tweaks and functionality unavailable with the stock launcher. One example of this is all of the cool stuff you can do to organize your app drawer.
Android is a highly customizable operating system, but that doesn't always apply to the apps you find on the Play Store. Most of the time, when you install an app, you're stuck with the default look and feel — but luckily, this isn't the case with Firefox. Unlike most other browsers, you can actually install themes to change the look of the top browser for Android.
If you're a regular reader of Next Reality, you're more likely to spread the joy of augmented reality than most others. But it can be difficult to introduce newbies into the AR fold if you don't give them exactly the right starting point in terms ease-of-use and affordability. But fear not, oh gift-giving AR pioneer, we're here to help!
I don't know about you, but I love options. Personally, I think Android's notification system is easy to use — providing access to new notification with a swipe down from the top of the screen. But, as Android users, we like the ability to do things differently whenever we see fit, so what if you wanted a different way? Well, with Action Launcher, this is possible.
Ex-Uber CEO and founder Travis Kalanick's bad and likely illegal behavior aside, his vision of not wanting to pay "the other dude in the car" has lead to a ground-breaking driverless test fleet.
That soil under your feet is not just dirt. It is teeming with life that may not change as fast as we would like when challenged by global warming.
Uber and Waymo's lawsuit is starting to pan out. Following a ruling on Monday, May 15, Judge Alsup, who called Waymo's patent infringement claims "meritless," ordered Uber to perform a series of actions and duties for Waymo. Without further ado, here's what Uber must do to begin to put this lawsuit behind them (well, maybe):
Hello people, I'm back for Part-3. In this part, as promised, we are going to create a client program and then we are going to test it with our server program made in Part-2.
For years, users have been clamoring for a "dark mode" theme in Android, but it has always seemed like Google is so committed to the white motif from their web services that such an option would never become a reality. But in a stunning turn of events, Google is finally embracing the idea with a night theme that will work in any app, and I'll cover all of the specifics below.
Alright so last time I gave you a homework assignment. This week we're gonna look at my version of the UDP-Flooder.

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.
I loved the original Star Wars trilogy when I was a kid, but loathe all of the current DVD, Blu-ray, and streaming versions available today. Ever since 1997, every version of A New Hope, The Empire Strikes Back, and Return of the Jedi has had horrendous CGI effects added in that George Lucas deemed necessary to bring his "ideal" version to life.
Hello fellow training hackers. I do not know if many of you are familiar with ruby, but since it is a useful scripting language, that hasn't been covered too much here on Null Byte, I thought why not do some How-tos about it now and then.
In python, or any scripting language for that matter, there are certain things that you will carry with you throughout your entire scripting career. Some of the most basic things that you will keep with you are output, variables, and their value types. We'll start by going over output, then cover variables and their types. So, let's get started!
Hi guys. I'm here to go for level 7 now lets get it start but i apologize u all that i posted this very late but now lets rock:

When you're scrolling through your iPhone's home screens, you'll inevitably reach the end and have to either swipe backwards or hit the Home button to return to the first page. Why Apple didn't instill an endless scrolling feature, or at the very least an option for it, is anyone's guess, but just because you can't do it out of the box doesn't mean you can't do it.
