You're out and about, and nothing on your iPhone will load. A glance at the settings shows a saved Wi-Fi network with full bars that your iPhone had connected to automatically, but you're not getting any internet. If you've experienced this, you're not alone, and there's something you can do about it. You'll even increase privacy and security on your iPhone in the process.
As protests surge in the wake of George Floyd's murder by a Minneapolis police officer, powerful photographs and videos from the demonstrations have gripped the world, putting our nation's very real and very justifiable widespread civil unrest out into the digital world. Unfortunately, these pictures could put you or others in danger if precautions aren't taken before uploading them online.
You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.
Compromised uTorrent clients can be abused to download a malicious torrent file. The malicious file is designed to embed a persistent backdoor and execute when Windows 10 reboots, granting the attacker remote access to the operating system at will.
In iOS 13, Apple added an important new feature to its HomeKit smart home ecosystem called HomeKit Secure Video. With it, you have a secure, private way to store and access recordings from your smart home IoT cameras.

If you've ever used the Find My iPhone and Find My Friends apps in iOS 12 and below, you may be surprised to hear that those apps have joined forces in iOS 13. Now, instead of two separate apps, they're combined into one convenient package. But what does that mean for you and your privacy and security?
A hacker with privileged access to a Windows 10 computer can configure it to act as a web proxy, which allows the attacker to target devices and services on the network through the compromised computer. The probes and attacks appear to originate from the Windows 10 computer, making it difficult to detect the attacker's actual location.
If you're looking to keep your conversations private, look no further than Telegram. Its cloud-based chats are secure and its optional end-to-end encrypted chats even more so, but you can't really prevent someone in the conversation from sharing your messages. However, you can lessen that chance by taking back your messages, deleting them for both you and the other end of the discussion.

There are nearly 100,000 unique onion service addresses online with over two million people using Tor every single day. Join me as I explore a small fraction of what the Tor network has to offer.
Web application vulnerabilities are one of the most crucial points of consideration in any penetration test or security evaluation. While some security areas require a home network or computer for testing, creating a test website to learn web app security requires a slightly different approach. For a safe environment to learn about web app hacking, the OWASP Juice Shop can help.
Developed by Open Whisper Systems, Signal is a free, open-source encrypted communications app for both mobile and desktop devices that allows users to make voice calls, send instant messages, and even make video calls securely. However, a vulnerability was recently discovered for the desktop version that can be turned into a USB Rubber Ducky payload to steal signal messages with a single click.

When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.
After numerous scandals like the Equifax data breach and the 2016 US election, cybersecurity has become a significant issue for Americans. Unfortunately, anytime we use our devices, we're open to a cyber attack — especially when we browse the web. However, there are ways that we can make it harder for hackers and data miners.

If maintaining privacy is an ongoing battle, the front line is your smartphone. Apple included several new security features in iOS 10, but at the same time, some of the best new functionality comes with potential privacy trade-offs that everyone needs to understand.
We are most certainly not machines. We all need some downtime every once in a while to set our sanity scales back in balance, which in turn, makes us more productive workers. This is a premise that several forward-thinking employers fully understand, but these types of companies are few and far between in corporate America.
By now, you've probably already installed 10.10 Yosemite, the newest version of Mac OS X, on your computer. While you most certainly noticed the visual changes, you might have missed some of the really cool additions.
The older I get, the more my Friday nights involve watching Netflix at home with a bottle of Maker's Mark and a box of Oreos. Netflix is a big part of my life, and I'm not alone. YouTube and Netflix make up over 50% of all activity on the Internet, so it might be worth your time to understand why Netflix seems to cause so many headaches and what can be done about it.
The iPhone has come a long way in its ten-year lifespan, but one thing still missing from the core user experience is native split-screen support. Sure, the displays on iPhones aren't nearly as large as an iPad's screen — which does offer "Split View" mode out of the box — but the iPhone 6 Plus, 6s Plus, and 7 Plus are definitely big enough to use two apps at the same time.
If you read my article on the OSI model, you got a good overview on communications from that model's perspective, but how does that relate to TCP/IP? We're going to take it a step further, getting into the idea behind the two address concept. How does an IP address and a MAC address work together? If you want to hijack sessions and all sorts of lulz like that, you need to understand these concepts. Let's get into it, mates!
Treasure may be buried as close as your own backyard. If you have some time to kill, try the art of treasure hunting. You’ll be sure to discover lots of interesting thing after learning how to use a metal detector to look for treasure.
The keyboard on your iPhone or iPad has a few new tricks up its sleeve with Apple's latest software updates, such as improved autocorrect and emoji stickers. However, a particularly hidden feature that lets you change the sound values of letters in other languages has gone unnoticed — until now.
Gmail uses TLS, or Transport Layer Security, by default for all email communications, so all of your emails will use the standard encryption as long as the recipients also support TLS. But there's a way to add even more security to your Gmail emails, and you can use your iPhone's Mail app to do it.

The All-Star Mac Bundle Ft. Parallels Pro gives you access to programs that will put your Mac to use and give you the best functionality out of it, and right now this whole bundle is on sale for $49.99.
