Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see whether we can make it crash or overflow. This process is known as fuzzing. It is often the first step to developing an exploit, as we need to find some variable that is susceptible to overflowing.
In this simple tutorial you will be shown step-by-step how to write local shellcode for use on 64-Bit Linux systems. Shellcode is simple code, usually written in assembly that is used as payload in exploits such as buffer overflow attacks. Payloads are the arrow head of an exploit: though the rest of the arrow is important for the delivery of the attack, the arrow head deals the killing blow. In reality, payloads are slightly less exciting yet far more interesting and intelligent than medieva...
Do you have an Alfa AWUS036NH Wi-Fi adapter that claims it can go to 2000 mWs, or some card that can supposedly transmit power over 1000 mW? If so, you may have run into problems setting your card's TXPOWER higher than 30 dBm, which is about 1000 mW. Well, I will show you how to break that barrier and go as high as you want!
If I were to lose access to the entire internet for the rest of my life, one of the websites I would miss the most would have to be Wikipedia. Wikipedia has ended countless arguments, informed me of how old and single some of my favorite actresses are, and helped me brush up on thousands of historical topics.
Apple News. Facebook. Twitter. Reddit. LinkedIn. These are just a few of the apps you probably have on your iPhone or iPad that keep you up to date on today's events. Unfortunately, they can also cause information overload. But a new viral speed-reading tool thinks it can help you process your daily news more efficiently.
With all the time most of us spend on our phones each day, wouldn't it be great if we could get rewarded for our addiction? Well, we can, thanks to various iPhone apps out there that can help us make a quick buck, earn cash back, donate freebies to charity, get complimentary cryptocurrency or stock, and receive other types of rewards.
When we got our first look at US Army soldiers testing Microsoft's modified HoloLens 2 last year, it still looked very much like the commercial edition, with some additional sensors attached.
After weeks of reports about their first augmented reality device, Apple actually shipped a real AR product this week in the form of a TV tie-in AR app.
Even if you pay for YouTube Premium, you are not exempt from ads. YouTube will stop adding pre-roll and interstitial ads, but content creators still have their own advertisements baked into videos. These product placements can be even worse than ads, and they're not the only annoyance embedded into videos. To put it nicely, YouTube is starting to have a problem with distractions.
It only takes a few commands to manipulate a MacBook's secure HTTPS traffic and pluck login passwords out of the encrypted data. Let's take Facebook and Gmail hacking to the next level by intercepting Safari and Google Chrome web traffic in real time.
In a surprising twist of expectation management, Magic Leap managed to not only ship but deliver the Magic Leap One I ordered on Wednesday by 4 p.m. PT on the same day.
Analysis of photographs and social connections can be a huge component of social engineering. Understanding who a person is, as well as who they know, can establish links within a company. This information could be used by hackers to execute elaborate social engineering attacks.
There's no doubt Kali has established itself as the most popular penetration distribution available. However, just because it's the fan favorite of beginners and security researchers doesn't make it right for everyone. Manjaro Linux is a beginner-friendly Arch-based distribution which can be easily weaponized with the Black Arch expansion, creating a friendlier first-time Arch experience.
Virtual private networks, or VPNs, are popular for helping you stay anonymous online by changing your IP address, encrypting traffic, and hiding your location. However, common IoT devices, media players, and smart TVs are hard to connect to a VPN, but we have a solution: Turn a Raspberry Pi into a router running through PIA VPN, which will ensure every connected device gets the VPN treatment.
Black Mirror, Netflix's technology-horror anthology, never fails to provide thought-provoking entertainment centered around emerging and futuristic technologies, and the third season's second episode, "Playtest," delves deep into the worlds of mixed, augmented, and virtual reality. While designed to leave you haunted by the end, offering a more "evil" narrative than we'll likely see in our actual future, the episode explores possibilities that aren't as far off as one might think.
If you're one who enjoys a good DIY project, or if you're just tired of paying exorbitant labor fees to have your vehicle serviced every 5,000 miles, changing your own oil can be a rewarding endeavor. Even though cars and trucks are becoming increasingly over-engineered these days, manufacturers generally see to it that the basic maintenance items can still be taken care of in your driveway with a few common tools.
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.
It's no secret that Apple's Notes app supports attachments such as photos, videos, and web links, as well as other file types like PDFs, word documents, spreadsheets, locations on a map, and audio tracks. While images, videos, and document scans are simple to add on an iPhone or iPad, other file types aren't as easy — at least until you know how.
Nova Launcher can be customized to do just about anything, but that can get overwhelming. If you're mostly interested in getting a Pixel-like experience, you'd normally have to spend all day tweaking mundane settings like dock padding and drop shadow placement. Well, we've already done that for you.
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.
Apple released iOS 14.5 developer beta 1, and the update sports a list of interesting features and changes. Some of those include support for the Xbox Series X and PS5 DualSense controllers, the ability to unlock your iPhone with Apple Watch, AirPlay 2 support for Fitness+, 5G support for dual-SIM setups, and a refreshed Software Update page in Settings.
Aside from home screen widgets, one of the most exciting updates to the iPhone with iOS 14 is Picture in Picture mode. With it, you can watch minimized versions of videos on top of other apps so you can multitask like a pro. However, not every service is on board with Apple's new features. YouTube is the primary culprit, but there is a workaround.
When it comes to cybersecurity, one layer isn't enough. A complex password (or one created with a password manager) does a good job of protecting your data, but it can still be cracked. Two-factor authentication strengthens this by adding a second layer of security, giving you even more protection against online threats.
There are more than a few subscription-based movie streaming apps available for Android and iPhone, each with different benefits and varying pricing plans. Needless to say, it can get expensive fast if you sign up for multiple services because you can't decide on what's best. Hopefully, we can help you out with choosing the right video-on-demand app to spend your hard-earned dollars on.
If you need to hack an Android device, try a remote administration tool. Known more familiarly as a RAT, there are open-source RATs that are barebones and exorbitantly priced RATs that are more polished. There are also low-cost and polished RATs that aren't intended to be RATs at all, such as Cerberus, an anti-theft solution available right on Google Play.
Smartphones are still "phones," which means communicating with others is usually a primary use. Ranging from a simple "hi" to a more personal conversation and even sharing passwords, our messages should remain private so that only the intended recipient sees their content. While many apps tout end-to-end encryption, not all apps prioritize security and privacy.
For all those times when an app either isn't available or simply won't cut it, your phone's internet browser provides access to your favorite websites and services. But some browsers are flat-out better than others, and chances are, the browser that came pre-installed on your phone isn't the best option out there.
Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time.
On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
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.
Seventeen years ago, Apple released iPhone, the first mainstream consumer phone with a touchscreen as its main typing input method. Apple has been perfecting its onscreen keyboard for almost two decades, and it's built with some fantastic features that make typing faster and easier. But it's easy to overlook some of these features, so here are some tips and tricks you need to be using if you aren't already.
You might have missed it, but the virtual keypad you use to enter phone numbers in your smartphone's dialer and contacts app isn't all numbers. Take a closer look, and you'll notice a few mysterious buttons you've likely been tuning out unconsciously. But it's time to stop ignoring them because each has a particular purpose that could come in handy one day.
In the past, Apple never really put much work into its Contacts app for iPhone, making the tool much less useful than its Mac and iCloud counterparts. But now the Contacts app for iOS is a force to be reckoned with. Packed with new features (some hidden), it's finally good enough to beat all of the third-party contacts apps that previously reigned supreme.
Over the past few weeks, Google, Snap, and Facebook have all taken their turns to show off their new augmented reality technologies. This week, it was Apple's turn, with new AR features for iOS 15 along with new capabilities for developers.
Finding an instrumental or karaoke version of a song can be pretty easy unless you're dealing with a song that isn't popular. That leaves you with just the full version of the song, complete with vocals. So how do you convert it into an instrumental or karaoke track?
GTFOBins and LOLBAS are projects with the goal of documenting native binaries that can be abused and exploited by attackers on Unix and Windows systems, respectfully. These binaries are often used for "living off the land" techniques during post-exploitation. In this tutorial, we will be exploring gtfo, a tool used to search these projects for abusable binaries right from the command line.
