Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
When hacking into a network during a penetration test, it can sometimes be useful to create your own wireless AP simply by plugging a Pi into an available Ethernet port. With this setup, you have your own backdoor wireless connection to the network in a matter of seconds. Creating an AP is also helpful while traveling, or needing to share a connection with a group of people.
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.
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.
Apple's controversial iMessage-editing feature in iOS 16, iPadOS 16, and macOS 13 Ventura is now less likely to be abused by malicious users.
Rumors about the 2022 iPhone series stirred well before the iPhone 13 models were even released. While Apple remains quiet on the next big iPhone, as it always does, we're seeing more and more leaks and reveals for the iPhone 14 series as we lead up to a likely fall release.
When Tim Cook, Craig Federighi, and other core Apple leaders take the stage for WWDC 2021 on June 7, we'll hear a lot about exciting new things to come. We're likely to see what's in store for watchOS 8 and macOS 12, but more importantly, we'll get a glimpse at what iOS 15 and iPadOS 15 will be like.
Google's been on a mission to improve the privacy and security of Android lately, and Samsung's always been at the forefront in these areas. As a result, One UI 3.0, which is based on Android 11, is the most secure OS version to ever hit Galaxy phones thanks to few key changes and new features.
Apple released iOS 13.7 for iPhone today, Tuesday, Sept 1, upgrading iOS' existing COVID-19 exposure notification feature. Now, US states no longer need to create an app to take advantage of exposure notifications. Instead, they can simply offer supports right to compatible phones.
Using your iPhone for a smart home remote just keeps getting better and better. Apple has consistently improved its HomeKit platform since the Home app came out, adding new features, tweaks, and refinements to the system with each update. And iOS 14 continues this trend with a few changes to help make your home even smarter and easier to use.
Samsung's stock Galaxy Themes system leaves much to be desired with its restrictive and expensive theme packs. Back in the day, the gold standard for Android theming was CyanogenMod Theme Engine. And while it no longer exists, a successor has emerged to fill the void.
In iOS 14, your iPhone can have home screen widgets, but you can also keep using widgets in the Today View if that's more comfortable for you. You could actually use both if you wanted. But when it comes to the Today View, the process for adding, removing, and editing widgets has changed.
Not trying to gatekeep here, but if you're not customizing things on your Android phone, you're doing it wrong. Still, I won't shame you for not knowing what to do if you take this time to learn how to make one of the biggest changes you can make.
The Pi-hole project is a popular DNS-level ad blocker, but it can be much more than that. Its DNS-level filtering can also be used as a firewall of sorts to prevent malicious websites from resolving, as well as to keep privacy-killing trackers such as Google Analytics from ever loading in the browser. Let's take a look at setting a Pi-hole up and customizing a blacklist to suit your needs.
There's not much to the Messages app for iPhone when it comes to finding the right conversations. It did get some enhanced search capabilities in iOS 13, but beyond that, there's no good way to find the threads you need aside from just scrolling through the main page, which lists newer ones first. However, there is a tweak that gives you the power to group like-minded chats together.
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.
Cases and stickers are always great, but they aren't the only way to customize an iPhone. The software on your device is full of customization options, from a better-looking home screen and cooler lock screen wallpapers to app icon changes and a system-wide dark mode. There's literally over 100 ways to make iOS on your iPhone genuinely unique, some of which are hiding in plain sight.
Apple unveiled the latest generation of its flagship earbuds, AirPods Pro, on Monday, Oct. 28. Aside from the increased price tag, new in-ear design, and wider charging case, the biggest change by far is in Active Noise Cancellation. Finally, we can listen to AirPods on a plane, walking by a busy road, anywhere with a lot of noise pollution. But how does it work?
With Google's new Pixel 4, we now have another device in the pool of phones designed for normal-sized hands. The other major player in this segment is as big as it gets — metaphorically. Apple's iPhone 11 Pro is the small phone to beat, but can Google be the one to dethrone it?
Beta testing Apple's mobile OS has never been more interesting. After eight seeds of iOS 13.0, Apple unexpectedly released the first beta for iOS 13.1, a whopping 23 days before iOS 13.0 made its public debut. Since 13.1, however, we haven't had any betas to sink our teeth into. That is, until now, as Apple just released the first developer beta for iOS 13.2 today, Wednesday, Oct. 2.
Apple Card has generated quite the buzz since its March 2019 announcement. The iPhone maker's new credit card pairs with Apple Wallet on your device, is simple to sign up for, includes enhanced security over other cards, has zero fees, and provides daily rewards right to your Apple Cash account. And as good as that sounds, the fine print can complicate things real quick.
While iOS 13 might have made waves for some of its more prominent features — most notably system-wide Dark Mode — some of the more interesting tools lie with its smaller, unannounced updates. One of those updates is a new Reminders setting to tag contacts in a to-do task so that iOS pings you when texting that person in Messages.
The OnePlus 7 Pro is definitely a beast on paper. With a specs page that ticks virtually every box and a price point that undercuts the competition by hundreds of dollars, it's hard to overlook this phone. But before you get too excited, know that OnePlus has repeatedly shown to be misleading with their official specs.
Apple released iOS 12.2 beta 4 to developers on Monday, March 4, and that means public beta testers will likely get the update on Tuesday. The update features a fresh "News" app icon, a new "Apple TV Remote" tile in Control Center, and a tweaked "About" page, in addition to seemingly under-the-hood updates. If you're not yet on the beta, now's your chance to see it for yourself.
Despite being at the helms of the RCS push, Google Fi has yet to support the new messaging protocol. It would've made too much sense if the Google-created MVNO was one of the first to support the feature Google's been pushing on other OEMs and carriers for years, but alas, they haven't. Well, better late than never — Google has finally announced support for RCS Universal Profile on Fi.
The most essential part of a healthy lifestyle is managing your diet — after all, what would be the point of a daily workout regimen if you were eating junk food? Thankfully, Samsung Health makes it easy to record your calorie and nutrient intake to get a clear picture of your dietary habits and how you can make them better.
With iOS 12, your iPhone's Messages app has more features than ever to enhance iMessage and FaceTime. Included in these changes are the new camera effects, which allow users to add fun and unique customizations to their photos and videos with the in-app camera in Messages. Stickers, Memoji, and more await the photos you take and send in Messages. ...
Apple released iOS 12 beta 9 to public beta testers on Monday, Aug. 27. The update comes at the same time as the release of dev beta 11.

Apple released the eleventh developer beta for iOS 12 to registered software testers on Monday, Aug. 27, only four days after the company unexpectedly released both dev beta 10 and public beta 8. Apple has ramped up its beta release schedule as of late, offering minor updates twice a week in the lead-up to iOS 12's official debut in a few weeks.
Can't say we didn't see this coming — Apple released iOS 12 public beta 7 on Monday, August 20, the same day it seeded the ninth version of the beta to developers. While the two betas may have different names, public beta 7 and dev beta 9 are virtually identical, so public testers shouldn't feel as though they are missing out.

Apple developers, check your iPhones — Apple released the eighth developer beta for iOS 12 on Wednesday, August 15. This update arrives just two days after the release of dev beta 7, which Apple quickly pulled after complaints of unusual performance and stability issues.
As a longtime Android user, one of the changes I was most excited about with Android Pie was the fact that the volume rocker finally controls media volume by default. However, the new way isn't ideal for everyone, but thankfully, there's an app that can change it back.
With all Android updates, there's a considerable wait before most phones get the new version, and Android Pie is no different. Until then, most of us are stuck just looking at videos of the newest update. Well thanks to developer Trey Dev, we can enjoy the new notification shade and Quick Settings menu while we wait.
Starting Nov. 1, 2018, Google got a lot tougher with Android app developers. New apps being uploaded to the Play Store already had to target Android 8.0 Oreo or higher as of August, but now, every update to existing apps has to do the same. It may seem like a simple rule, but it will have some serious repercussions.
During an event in Moscow earlier this year, Nokia announced a refresh to their Nokia 2, 3, and 5 series phones. While there is no official confirmation of a US release for the updated Nokia 2 and 5, we do know that as of July 2nd, you'll be able to snag a new Nokia 3.1.

Over the years, the internet has become a dangerous place. As its popularity has increased, it has attracted more hackers looking to make a quick buck. However, as our dependency on the web grows, it becomes increasingly difficult to sever all ties. This means we have to protect one of our weakest points, the password.
Huawei's sub-brand, Honor, just announced a pair of new smartphones to help close out the year.
