PRL, or Preferred Roaming List, basically tells your phone which towers to connect to first. Changing PRLs can improve reception and data speeds, and in some cases even give you access to corporate/test towers.
Do you ever wonder how all these celebrities continue to have their private photos spread all over the internet? While celebrities' phones and computers are forever vulnerable to attacks, the common folk must also be wary. No matter how careful you think you were went you sent those "candid" photos to your ex, with a little effort and access to public information, your pictures can be snagged, too. Here's how.
It might be time to move those Instagram photos to another service. It seems that Instagram has never heard of the phrase, "If it ain't broke, don't fix it." In a very big WTF moment, the extremely popular photo sharing and editing app decided that it has the right to sell its users photos to third parties without pay or notice. Yep, you heard that right. That photo you took of your girlfriend laying out on the beach could be in the next stupid Corona commercial without your consent and witho...
People take their Black Friday shopping seriously. Some of them are even willing to fight over it. Every year the stories get crazier and crazier, and someone always gets hurt (or even killed).
Building a DIY Alarm System: The Concept So, you want to protect your property, or maybe a room, car, or even your backyard. The concept of an alarm system is to notify the "alarm administrator" that there is an intruder entering the previously designated boundaries. The triggers for this boundary could be as simple as a pressure sensor, or as complicated as a laser network. They all do the same thing, but some work better than others.
In this video series on spun glass, expert Tom Wright takes you through the steps of making a spun glass pendant with imploded colors. He introduces you to safety concerns and the materials you will need, followed by a demonstration of all the steps needed to make you own spun glass pendant with implosion.
While Apple is full steam ahead on iOS 18, which is expected to drop sometime next month, it hasn't forgotten about iOS 17, which still dominates most users' iPhones. On Aug. 19, Apple issued a rerelease of its iOS 17.6.1 software for iPhone.
It's nearly impossible to comfortably lay down on your bed or couch with headphones on. Sure, you can position yourself so that your headphones don't touch anything, but that usually means facing up at the ceiling, which is a huge no if you're watching something on Netflix or listening to music on your side.
The ability to browse the web in coffee shops, libraries, airports, and practically anywhere else you can imagine is more than convenient, but convenience has risks. Using public Wi-Fi allows others to spy on you easily. Even your own internet service provider can see every website you've ever visited. Don't fall into the trap of protecting your identity, data, and devices after it's too late.
Quietly, while the rest of the world was engaged in pandemic and political concerns, a few weeks ago Facebook casually upgraded its Spark AR platform with what it calls Unified Effect Publishing.
In a departure from Apple's newer iPhone models with Face ID technology, the 2020 iPhone SE goes back to the old days where the Home button ruled, and Touch ID was the biometrics method. But if you've never owned an older iPhone with a Home button, something as simple as shutting down and restarting the iPhone SE could elude you.
Without admin privileges, installing additional software, or modifying the Windows 10 firewall, an attacker can alter a router and perform a variety of exploits. It's accomplished by forwarding requests from Kali through a backdoored Windows computer to the router gateway with simple SSH tunnels.
There are times when leadership is tested. This is one of those times. As government and business leaders around the world are grappling with the unfolding coronavirus pandemic, the real-time responses to the crisis from many leaders have been great and, at times, less-than-optimal.
Smartphones are more like computers than actual telephones. Unfortunately, thieves, hackers, and other bad actors know this and are always looking to make money off your personal data. Thankfully, your Galaxy S20, S20+, or S20 Ultra has tools to combat these threats — as long as you know where to look.
With all the talk about privacy concerns recently, Google's name keeps coming up because they are a very data-driven company. As an Android user, they know basically everything about you based on your device usage. That can easily scare some people off who are worried about their privacy and security. You do have some say in what personal data Google controls, but what if you want total control?
It's been said time and time again: reconnaissance is perhaps the most critical phase of an attack. It's especially important when preparing an attack against a database since one wrong move can destroy every last bit of data, which usually isn't the desired outcome. Metasploit contains a variety of modules that can be used to enumerate MySQL databases, making it easy to gather valuable information.
While you might suspect your MacOS computer has been infected with malware, it can be difficult to know for sure. One way to spot malicious programs is to look for suspicious behavior — like programs listening in on our keyboard input or launching themselves every time we boot. Thanks to free MacOS tools called ReiKey and KnockKnock, we can detect suspicious programs to discover keyloggers and other persistent malware lurking on our system.
As part of the iOS 11 update, Apple added a document scanner function that creates high-quality digital copies of physical documents, but it was only available inside the Notes app. With iOS 13, Apple has built its scanner right into the Files app, enabling you to quickly create PDFs with your iPhone and do more with them.
Firewall solutions for macOS aren't impervious to attacks. By taking advantage of web browser dependencies already whitelisted by the firewall, an attacker can exfiltrate data or remotely control a MacBook, iMac, Mac mini, or another computer running macOS (previously known as Mac OS X).
For those with small hands, smartphones have gotten out of control as of late. Nearly every flagship phone is over six inches in length, so many are forced to use phones that are too big for them and hope they don't fall. Well, thanks to one developer, using these phones can be a lot easier.
KeePassX, 1Password, and LastPass are effective against keyloggers, phishing, and database breaches, but passwords managers rely on the operating system's clipboard to securely move credentials from the password vault to the web browser. It's within these few seconds that an attacker can dump the clipboard contents and exfiltrate passwords.
Apple's scheduled to show off the first look of iOS 13 at WWDC 2019 on June 3, but what will the new operating system hold for iPhone? Rumors suggest that many features initially planned for iOS 12 will show up in iOS 13, codenamed "Yukon," and dark mode will be the big ticket item this year.
In just a few weeks, on May 29, the annual AWE (Augmented World Expo) conference will take place once again in Silicon Valley (Santa Clara, California, to be exact).
On Monday, Apple unveiled its Apple Card, the company's boldest move yet toward becoming a truly mainstream mobile payments company. And the product has vast implications for our augmented reality future, some of which may not be immediately obvious to many.
With a simple social engineering trick, sudo passwords can be captured in seconds without the target's knowledge. The passwords can then be saved to a file or exfiltrated to another computer on the network.
When it comes to digital security, one of the best ways to protect yourself is to use two-factor authentication. Most apps these days support it, including Facebook, a site where the more privacy you can muster, the better. However, of the two 2FA options available for Facebook, only one should be used as the other will share your phone number with the world, a huge privacy concern.
Switching phones has never been easier. Google backs up most of your app data on the cloud, which can then be restored onto your new phone. Sadly, Signal doesn't use this feature since it could compromise your security. Instead, Signal stores encrypted backups locally, requiring a bit of work to restore these messages.
While the United States, in general, doesn't have the worst overall pollution, the air quality can drastically change from one day to the next. If you're particularly sensitive to pollutants in the air, there are apps that show how clean or polluted the air is in your area, as well as in cities you plan on traveling to, but Apple's making those apps less relevant with a new feature in Apple Maps.
The last time we heard from Meta, the makers of the Meta 2 augmented reality headset, things looked pretty bleak. Now, as several new facts have come to light, we have confirmation regarding the beleaguered company's fate: Meta is done.
One of the ultimate goals in hacking is the ability to obtain shells in order to run system commands and own a target or network. SQL injection is typically only associated with databases and their data, but it can actually be used as a vector to gain a command shell. As a lesson, we'll be exploiting a simple SQL injection flaw to execute commands and ultimately get a reverse shell on the server.
Waking up your Apple Watch to see "your heart has shown signs of an irregular rhythm suggestive of atrial fibrillation" might come as a shock. While your watch can send you warnings if it detects a fast or low heart rate, those messages are pretty vague, while the abnormal arrhythmia alert can downright scary. So what should you do if you receive one of these AFib notifications?
Many online users worry about their accounts being breached by some master hacker, but the more likely scenario is falling victim to a bot written to use leaked passwords in data breaches from companies like LinkedIn, MySpace, and Tumblr. For instance, a tool called H8mail can search through over 1 billion leaked credentials to discover passwords that might still be in use today.
Huawei has been in a losing battle with the US government for around ten years, with the last year being the spike of Huawei's problems. Because of US pushback against some Chinese-based smartphone manufacturers due to security concerns, Huawei is hoping to limit its dependency on US-based companies, and recent rumors of Huawei's very own mobile operating system may be the first step.
With new iPhone models out, you'll have updated cameras to try out, a faster processor, and new colors to choose from. The only thing that could stop you from picking one up yourself is, well, your current iPhone. Here's how to check if you're eligible to upgrade to iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, or any other iPhone still being sold.
As penetration testers, we sometimes need to securely store customer data for prolonged periods. Bruteforce-resistant, vault-like containers can be created with just a few commands to protect ourselves from physical attacks and unintended data disclosures.
It's always a good idea to know how an attack works at the very basic level. Manual techniques for exploitation often find holes that even the most sophisticated tool cannot. Sometimes, though, using one of these tools can make things so much easier, especially if one has a solid foundation of how it works. One such tool can help us perform a cross-site request forgery with minimal difficulty.
Web 2.0 technology has provided a convenient way to post videos online, keep up with old friends on social media, and even bank from the comfort of your web browser. But when applications are poorly designed or incorrectly configured, certain flaws can be exploited. One such flaw, known as CSRF, allows an attacker to use a legitimate user's session to execute unauthorized requests to the server.
In a surprise twist, Apple released iOS 12 public beta 8 to software testers on Thursday, Aug. 23, right alongside iOS 12 dev beta 10. The release comes as a bit of a shock, as the company released iOS 12 public beta 7 just three days earlier. The official build of iOS 12 now feels closer every day.
After years of struggling, it appears BlackBerry has finally figured out how to update its iconic design for modern times. The BlackBerry KEY2 pays homage to past devices such as the Bold 9000 while adapting to modern times with the Android OS. The result is a device that might be the best BlackBerry to date.
There's always an iPhone in our list of top phones for privacy and security, due in large part to advanced security measures like Face ID, consistent iOS updates, and easy ways to prevent unwanted access and excessive data sharing. However, some of those options actually do the opposite and hinder security. It all depends on how you use your iPhone, but you should at least know everything available.
