Now we'll learn how to secure PDFs so that we can safely send them out to clients for review and be assured that they can only access the content the way we want them to. Turn off things like printing and content extraction. Password protect your PDFs so that they can't even be opened without a password.
The only thing better than programming MicroPython is programming MicroPython over Wi-Fi. So once you set up MicroPython on a microcontroller and have it on its own power source, you won't need to use a data cable to connect to it whenever you need to interact with it, program it, upload files, or grab data.
While we haven't covered Amazon Web Services, or AWS, on Null Byte before, Amazon's cloud computing platform is ripe for attack by hackers, pentesters, and cybersecurity researchers. It's also an excellent cloud hosting service to build or use vulnerable-by-design AWS setups and frameworks.
The next libSSH or OpenSSH exploit may be just around the corner. Keep your SSH service out of Shodan's database before hackers find new ways to bypass the password protecting the server.
As we aim for a wireless world, technology's reliance on cloud computing services is becoming more apparent every day. As 5G begins rolling out later this year and network communications become even faster and more reliable, so grows our dependency on the services offered in the cloud.
Many guides on Null Byte require using the Secure Shell (SSH) to connect to a remote server. Unfortunately for beginners, learning to use SSH can become a confusing mix of third-party programs and native OS support. For Chrome OS users, using SSH is even more difficult. We'll fix this by using the Chrome Secure Shell to establish an SSH connection from any device that can run a Chrome browser.
With Virtual Network Computing, you don't need to carry a spare keyboard, mouse, or monitor to use your headless computer's full graphical user interface (GUI). Instead, you can connect remotely to it through any available computer or smartphone.
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.
In one of my previous articles, I discussed ShinoBot, a remote administration tool that makes itself obvious. The goal is to see if the user could detect a remote administration tool or RAT on their system. In this article, I'll be demonstrating the use of Pupy, an actual RAT, on a target Ubuntu 16.04 server.
Deleting emails can be a tedious process on the iPhone, especially since the "Trash All" options have been removed ever since iOS 10 first came out. Though likely well-intentioned, this change places an undue burden on all of us iPhone owners who now have to erase emails individually.
True innovation tends to come from the places we least expect as developers. The Microsoft HoloLens is still a very new product, and some of the other headsets are still just ideas, so the rules for mixed reality are not set in stone. That means all the real problems to be solved are yet to come.
Welcome back, my novice hackers! You have probably heard of the Panama Papers hack by now. This was a hack of the servers at Mossack Fonseca, a major law firm in Panama. This law firm specializes in assisting the rich and powerful to hide their wealth from taxes and scrutiny by creating tax havens overseas.
Hello everyone! I hope you are having a great day so far. Today, instead of caring about networks we are going to talk about subnetting based on host requirements as promised in my first article about subnetting. Just like in the previous articles we will jump right into the examples because that's the best way to learn.
Ever since the Google Play Store removed its "Designed for tablets" section, it's been a lot harder to find good, tablet-optimized Android apps. Not that it was all that great to begin with considering that they used to list apps like Facebook and Twitter, which only have oversized phone UIs on tablets, not actual customized UIs.
Greetings aspiring hackers. I have observed an increasing number of questions, both here on Null-Byte and on other forums, regarding the decision of which USB wireless network adapter to pick from when performing Wi-Fi hacks. So in today's guide I will be tackling this dilemma. First I will explain the ideal requirements, then I will cover chipsets, and lastly I will talk about examples of wireless cards and my personal recommendations. Without further ado, let's cut to the chase.
Welcome back, my hacker novitiates! In an earlier Linux Basics tutorial, I had demonstrated the basics of the Apache web server. Since Apache is the world's most widely used web server on the Internet (as of July 2015, Apache was 38%, IIS was 26%, and Nginx is 15%), the more you know about it and understand it, the more success you are likely to have hacking it.
It's been a while when the major web browsers first introduced HTTP Strict Transport Security, which made it more difficult to carry Man In The Middle (MITM) attacks (except IE, as always, which will support HSTS since Windows 10, surprised?).
Google made a huge splash this year in their annual Google I/O with an awesome announcement regarding their Photos app. Although I was primarily interested in the details surrounding Android M, my ears instantly perked up when Google announced that their Photos app will now offer free, unlimited, high-quality storage.
Hi, dear co-apprentices and wise masters. I've been recently trying to learn the basics to hacking here, and I've read all guides on Wi-Fi hacking and noticed no word is dedicated to this awesome script that comes bundled with Kali!
Part 1: What is Popcorn Time? Part 2: What is a torrent?
Welcome back, my novice hackers! Before we try to attack a website, it's worthwhile understanding the structure, directories, and files that the website uses. In this way, we can begin to map an attack strategy that will be most effective.
With its growing popularity, it's clear that the Chromecast isn't going away anytime soon, with options for casting games, cloud files, music, and much more. But not all content providers are in a hurry to add support for the device, and SoundCloud is one of them. While My Cloud Player is by no means an official SoundCloud app, it comes pretty darn close.
Welcome back, my fledgling hackers! A short while ago, I did a tutorial on conducting passive OS fingerprinting with p0f. As you remember, p0f is different from other operating system fingerprinting tools as it does not send any packets to the target, instead it simply takes packets off the wire and examines them to determine the operating system that sent them.
Welcome back, my novice hackers! There are SOOOO many ways to hack a system or network, which means you need to think creatively in order to be successful.
Welcome back, my greenhorn hackers! In my continuing effort to demonstrate to you how to hack the ubiquitous Windows 7, we will going after that notoriously vulnerable Adobe Flash that is on nearly every client Windows system (you are not likely to find it on servers).
Welcome back, my rookie hackers! When Wi-Fi was first developed and popularized in the late '90s, security was not a major concern. Unlike wired connections, anyone could simply connect to a Wi-Fi access point (AP) and steal bandwidth, or worse—sniff the traffic.
Welcome back, my fledgling hackers! In the first part of my series on Wi-Fi hacking, we discussed the basic terms and technologies associated with Wi-Fi. Now that you have a firm grip on what Wi-Fi is exactly and how it works, we can start diving into more advance topics on how to hack Wi-Fi.
Google Reader is soon to be no more. Yesterday, the company announced that the service will be shutting down as of July 1, 2013, as part of Google's second "Spring Cleaning."
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.
Send an email prematurely? Forgot to attach a file? Accidentally addressed it to the wrong person? It happens to the best of us. But what can you do to get it back? Hack into the other person's email account and delete the email before they get a chance to see it? Unless you're a hacker extraordinaire, that option is unlikely. So, what can you do? If the email has already been sent, you're probably out of luck. Even if they didn't read it yet, your chances of retrieving it are slim. But some ...

If your old clothes are of high quality and in good shape, selling them on consignment is an easy way to make cash quickly.
You may not always want to, but there will probably be a time when you'll want to know if an email you send — like a job application or a support request — is opened by the recipient. It's actually easy to implement, and you may be using an email client on your device right now that supports email tracking.
Since its release back in 1988, Microsoft Office has been the top client and server software suite for businesses around the world. Office's domination is thanks to both Microsoft's extraordinary foresight and their continual updates and innovations to ensure that companies always get what they need.
As a meeting host on Zoom, you can't control what a participant does during your live video call, but you do have the power to turn off their camera so that other people aren't subjected to distractions. So if you catch someone in your call purposely making obscene gestures or accidentally exposing themselves while using the bathroom, you can block their camera, as long as you know how.
If you're tired of the so-called "top" tweets appearing first in your Twitter timeline instead of only the latest from the people, companies, and bots you follow, there's a way to get rid of them.
For Snapchat users wondering if that selfie is ready to send to their crush, independent Lens Studio creator Andrew Mendez created a handy tool called the Smile Rater.
If your job revolves around prospective clients and customers, you may frequently receive iMessages from unknown numbers. Although this isn't necessarily a bad thing, being bombarded with messages from strangers can create disarray in your inbox if you're not careful. Luckily, Apple makes it easier to organize your conversations by allowing you to filter unknown numbers in the Messages app.
After one of Britain's "Brothers Bling" bought Blippar out of bankruptcy, the mobile augmented reality company is getting back to business with the addition of web-based AR capabilities to its platform.
