Welcome back, my rookie hackers! As hackers, we are often faced with the hurdle of cryptography and encryption. In some cases, we use it to hide our actions and messages. Many applications and protocols use encryption to maintain confidentiality and integrity of data. To be able to crack passwords and encrypted protocols such as SSL and wireless, you need to at least be familiar with the concepts and terminology of cryptography and encryption.
Hello people again, I wrote my last post about crypto about 10 months ago, now I will introduce something not fresh for the science, but fresh for the people who wants to learn. In my http://null-byte.wonderhowto.com/forum/cryptography-0161538/ post of crypto concepts, there is just basics, today we will see something that targets wide concepts like Symmetric crypto, Public Key Cryptography, Hashing, Keys etc...
Cryptography is the science of keeping secrets, or more specifically, the science of disguising them. As a point of fact, cryptography has progressed quite a bit farther and now encompasses file and message integrity, sender authentication, and pseudo-random number generators.
Greetings my fellow hackers, In the previous article, I discussed briefly about ransomwares and their devastating capabilities. Devastating in a way that ransomwares are not only known to encrypt files but to also lockout some specific functions of the system and hold it up for a ransom.
Fascinating, although admittedly highbrow, discussion on the history of cryptography from the BBC. If you are outside of the UK and don't know how to access BBC content you need to spend a bit more time browsing the Null-Byte forums ;-) http://www.bbc.co.uk/programmes/b06mtms8
Cryptography is a quintessential part of computer security in the modern world. Whenever you buy something on eBay or log into Facebook, that data is encrypted before it's sent to the server in order to prevent third parties from eavesdropping and stealing your sensitive information.
Last time, we looked at archaic cryptography, so you should have a basic understanding of some of the concepts and terminology you'll need. Now, we'll discuss one of the most important advances in computer security in the 20th century—public key cryptography.

It has been a long while since I last came here to write an article. Graduate school keeps you busy. After I looked over what I had written previously, I decided that I should introduce another fun topic from cryptography. In this case, steganography.
If you haven't read the last article, feel free to stop by and give it a read, but abstaining from reading it will not, for the most part, be detrimental to your understanding.
Welcome back, my neophyte hackers! Metasploit is such a powerful tool that I can only scratch the surface of its capabilities here. As it has developed over the years, it is now possible to use Metasploit for nearly everything from recon to post exploitation to covering your tracks. Given its versatility, every aspiring hacker should have at least a tentative grasp of Metasploit.
Since I first announced the new Null Byte recognition for excellence a few weeks ago, several of you have written me asking, "How can I study for this certification exam, and what material will be covered on the exam?" Now I have an answer for you. The White Hat Hacker Associate (CWA) will cover 14 domains or areas. Everything you need to know is here on Null Byte. There will be no questions that are not covered here on this site, guaranteed.
In order to increase the security and harden the integrity of an email account and its content, you'll want to use PGP on your Windows, macOS, or Linux computer. This is usually the first thing security analysts do to protect communications with encryption, and everyone else should consider it too, especially since there's an easy way to incorporate PGP that anyone can follow.
It can be hard to get all of your friends, family, coworkers, and acquaintances to jump on board with the more-secure email system ProtonMail, but that doesn't mean you can't still send them encrypted emails. Best of all, they won't even have to install any other apps or extensions to read or reply to the messages.
Ever since the FBI took down the Silk Road and Dread Pirate Roberts last month, many questions have been raised about whether Tor still provides anonymity or not, and if it's now broken. I'll try to address that question here today succinctly from multiple angles, keeping it as simple and plain-language as possible. The Closing of Silk Road
Over the past decade the Internet community has been witness to the rise of many new forms of online interaction. These new technologies have given rise to anonymous networks (like TOR), black markets within the deep web network (like the Silk Road), and even forms of digital currency, or more accurately crypto-currencies, such as Bitcoin. All of these technological advancements have contributed to securing users around the world and protecting their privacy. Therefore it is no surprise that ...
This is an easy step by step tutorial how to lock your jewels in a hotel room or in a public safe. Be aware that in a public safe it is more secure to use the second method of locking by a magnetic card, not by a PIN code that can be easily seen by someone nearby.
Many of my aspiring hackers have written to me asking the same thing. "What skills do I need to be a good hacker?"
I love cryptography. It is like a great gigantic puzzle for me to solve. However, it is more important than that. It is also how we keep secrets safe. Not just sorta safe either, but really safe.
Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
Increasingly, cutting-edge platforms like blockchain technology and augmented reality are overlapping, forging new digital frontiers that promise to change the way we interact with the virtual and the real world.
Apple released an iOS 11.2.2 update on Monday to iPads, iPhones, and iPod touches. The update comes as no surprise since news broke last week of a massive security vulnerabilities, named Meltdown and Spectre, which are found in smartphone chips throughout the industry. This update in large part addresses the security risks imposed by these chip flaws.
Hello guys I am ROMEO 64 (sounds weird I guess but who cares. :D).. Alright....Ever wondered what happens when you login to your Facebook account?
This is my first tutorial on this website. So, if you think anything to be wrong, just place it in the comments.
Welcome back, my amateur hackers! As many of you know, Null Byte will soon be re-establishing its IRC channel. In preparation of that event, I want to show how to set up a secure IRC client with OTR, or Off the Record.
Sometimes our information important. So important that we have to encode it to keep it away from criminals. What better way to encode information than to make our own encoder with Python?
In spite of the degree of difficulty it is to install, CyanogenMod has steadily climbed the ladder to become one of the most popular third-party firmwares for Android devices.
Your social security number, credit card information, and medical history can fall into the wrong hands if you're not careful about how and where you share your data online. If you really care about your data, there are tools and techniques you can utilize to protect yourself from cyberstalkers, advertisers, and hackers in a time when digital lives are a high commodity.
Passwords stored in web browsers like Google Chrome and Mozilla Firefox are a gold mine for hackers. An attacker with backdoor access to a compromised computer can easily dump and decrypt data stored in web browsers. So, you'll want to think twice before hitting "Save" next time you enter a new password.
If you've received a spam message in Signal Private Messenger, you know that anyone can contact you as long as they have your linked phone number. But when it comes to the people you're actually trying to have a private conversation with, how do you know it's really them?
Welcome to the Part 2 of the series 'Cryptocurrency'. It has been late because of some errors, where all I typed was lost.
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.
NOTICE: Ciuffy will be answering questions related to my articles on my behalf as I am very busy. Hope You Have Fun !!!
Welcome back, my rookie hackers! "How can I travel and communicate over the Internet without being tracked or spied on by anyone?" It's a question many Null Byteans have asked me, so I have decided to write a comprehensive article addressing this issue.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
When you want to install a new tool or game on your iPhone, you go straight to the App Store to do so — but it's not the only place you can get apps from. Some developers use back alleys to get their apps to you, while others can trick you into installing them without giving it much thought. This can lead to malicious software running on your iPhone, software you'll want to get rid of asap.
A rainbow table can be thought of like a dictionary, except instead of words and their definitions, it holds combinations of characters on one side and their hashed form on the other. What is a hash and why would you want to know what random combinations of characters are hashed into?
Ransomware is software that encrypts a victim's entire hard drive, blocking access to their files unless they pay a ransom to the attacker to get the decryption key. In this tutorial, you'll learn how easy it is to use the USB Rubber Ducky, which is disguised as an ordinary flash drive, to deploy ransomware on a victim's computer within seconds. With an attack that only takes a moment, you'll need to know how to defend yourself.
