Hashes are commonly used to store sensitive information like credentials to avoid storing them in plaintext. With tools like Hashcat, it's possible to crack these hashes, but only if we know the algorithm used to generate the hash. Using a tool called hash-identifier, we can easily fingerprint any hashes to discover the right Hashcat mode to use to retrieve a password.
Microsoft Office files can be password-protected in order to prevent tampering and ensure data integrity. But password-protected documents from earlier versions of Office are susceptible to having their hashes extracted with a simple program called office2john. Those extracted hashes can then be cracked using John the Ripper and Hashcat.
A powered-off MacBook can be compromised in less than three minutes. With just a few commands, it's possible for a hacker to extract a target's password hash and crack it without their knowledge.
Greetings all. I'm back with another informational review of the diversity of utilities for use in the sphere of hacking at your disposal. Today we are going to cover the insides of CUPP (Common User Passwords Profiler) in its entirety. The tool is very basic in nature, as there is little to no configuration needed to get cracking (worst pun ever). So let's get started, shall we?
Welcome back everyone. I apologize for the lack of training articles, but I've been rater busy lately. I've recently picked up a second job and my college courses are now back in session, so I'm a bit strapped for time.
While password cracking and WPS setup PIN attacks get a lot of attention, social engineering attacks are by far the fastest way of obtaining a Wi-Fi password. One of the most potent Wi-Fi social engineering attacks is Wifiphisher, a tool that blocks the internet until desperate users enter the Wi-Fi password to enable a fake router firmware update.
With an ordinary birthday card, we can introduce a physical device which contains malicious files into someone's home and deceive them into inserting the device into a computer.
First of all, I hope the title makes sense. :D Well, this is basically creating a program that can help with dictionary attacks. Generate possible passwords. It pretty much lies in you knowing the person you want to hack.
Welcome back, my novice hackers! This is the third installment of my Python scripting series. If you haven't read the previous two articles, take some time now to go back and read Part 1 and Part 2 before you proceed here.
Everybody knows not to store sensitive information in unencrypted files, right? PDFs and ZIP files can often contain a treasure trove of information, such as network diagrams, IP addresses, and login credentials. Sometimes, even certain files that are encrypted aren't safe from attackers. That's where Zydra comes in — a tool for cracking RAR files, ZIP files, PDF files, and Linux shadow files.
In this article, we will build a parallel password cracker using the techniques explained in the previous part. As SHA-512 is the digest function that Kali (and most modern Linux distributions) use to store our passwords, we will make a SHA-512 password cracker.
lubuntu is a is a lightweight Linux/Ubuntu that makes it suitable to virtual environments, that you run with VirtualBox to add a secondary machine to your computer or laptop. With this program you can run a number of operating systems upon the same platform.
Hello, my fellow hackers. My name is cl0ck. I am a senior majoring in Computer Engineering with an emphasis is Security. I have been lurking the site for a while now reading and learning from the great minds that reside here. I, too, have some knowledge that I would like to share with all of you. This post actually comes from a personal problem I faced and had to find a solution for. Without further ado, here it is:
What's your Twitter handle worth? If it's considered "desirable" (aka short and simple), it'll get you around 100 bucks, or, if you prefer, the affections of a teenage girl.
Earlier this week, Spiderlabs' vulnerability researcher Jonathan Claudius discovered a key in Windows 7 and 8 registries that makes it easy for anyone with physical or remote access to a computer get a hold of the user's password hints. When the "UserPasswordHint" key is read, the hints are displayed as a code that looks encrypted, but Claudius noticed a pattern of zeroes that could be easily translated back to plain text with a decoder he made in Ruby. He added this functionality to the Meta...
It looks like there is a fatal flaw in the current macOS High Sierra 10.13.1, even straight from the login menu when you first start up the computer. This severe vulnerability lets hackers — or anyone with malicious intentions — do anything they want as root users as long as they have physical access to the computer.
Greetings fellow students! I'm currently reading a book called "Violent Python: A Cookbook for Hackers, Forensic Analysts, Penetration Testers and Security Engineers"
Welcome back, my nascent hackers! Like anything in life, there are multiple ways of getting a hack done. In fact, good hackers usually have many tricks up their sleeve to hack into a system. If they didn't, they would not usually be successful. No hack works on every system and no hack works all of the time.
Greetings. This how-to on hacking Windows 7/8/10 etc. admin account passwords using Windows Magnifier is focused on adding, changing, or deleting an admin level account on a Windows 7/8/10 etc.
Welcome back, my budding hackers! One of the keys to becoming a professional and successful hacker is to think creatively. There is always a way to get into any network or system, if you think creatively. In previous tutorials, I have demonstrated ways to crack passwords on both Linux and Windows systems, but in this case, I will show you a way to get the sysadmin password by intercepting it from a Remote Desktop session.
The pictures we upload online are something we tend to think of as self-expression, but these very images can carry code to steal our passwords and data. Profile pictures, avatars, and image galleries are used all over the internet. While all images carry digital picture data — and many also carry metadata regarding camera or photo edits — it's far less expected that an image might actually be hiding malicious code.
A powered-off Windows 10 laptop can be compromised in less than three minutes. With just a few keystrokes, it's possible for a hacker to remove all antivirus software, create a backdoor, and capture webcam images and passwords, among other highly sensitive personal data.
In the previous article, we learned how to set up our VPS, configure our PHP server, and developed an in-depth understanding of how the payload works. With all that taken care of, we can get into disguising our payload to appear as an image and crafting the note in the greeting card being delivered to our intended target.
In Linux, all password hashes are normally stored using the MD5 hashing algorithm in the /etc/shadow file, but MD5 is algorithmically weak due to collision vulnerabilities. The new recommended standard are the higher level SHA-2 hashing algorithms, SHA256 or SHA512. As a friend pointed out to me, Ubuntu is currently the only distro implementing SHA-2 as the default. With SHA-2, your passwords take an unreasonably larger amount of time to calculate. This will greatly decrease how many password...
Back when I was a Windows user, I know I'm not the only one who has experienced password loss—that moment where you just can't remember your password. Sometimes it happens to the best of us. So, how can we get into the system without paying a local geek or geeksquad to do it? First, we have to look into how Windows stores their passwords.
Welcome to the second Null Byte in a series educating you on Social Engineering awareness and techniques. Today, I'm going to show you how a saavy Social Engineer would trick a friend into unknowingly surrendering their Facebook password. My intent is to warn and demonstrate how easy it is to succumb to phishing via Social Engineering, and therefore expose yourself.
Password strength and encryption are important things when it comes to computers. A password is the entire security of your computer, and OS passwords are not hard to break. Most users believe that if you have a password on your computer via the OS, that you are safe. This is not true at all, sadly.
When Windows stores a password, it is done so by hashing the password in an LM hash and putting it in the Windows SAM file. In the scary moment that you lose your password, but don't want to pay some geek to have full root access to your computer, you need to recover it using Ophcrack. Ophcrack doesn't remove the password, or bypass it, it cracks the password hash using rainbow tables.
Our mission for this week's Community Byte was to create a Python program to crack web-based passwords, like the ones you would see on an email or router login. I wanted it to be universal in the sense that it could be easily modified and adapted to another website just by changing a few variables. That was a success! Even though people weren't on time to the coding session, everything went well.
There is a near-infinite amount of ways a computer can be broken into. But that does not mean that there isn't a reason to secure our computers as best as we possibly can. It's like the principles of a secure house. Which are the most secure houses? The ones with locks and advanced alarms, obviously, but not for the reasons people normally think.
Welcome to another Community Byte announcement! In the past two sessions, we have coded an IRC bot in Python capable of issuing commands. Since it can issue commands and most of you are new to programming, that project will stay idle for a while. Other commands such as voice and half-op can be easily hacked in via common sense, even if you weren't there for that session.
These days I found a very beautifull python script that just prints the google chrome usernames and passwords that are stored on your machine.

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.
Hacking Wi-Fi is a lot easier than most people think, but the ways of doing so are clustered around a few common techniques most hackers use. With a few simple actions, the average user can go a long way toward defending against the five most common methods of Wi-Fi hacking, which include password cracking, social engineering, WPS attacks, remote access, and rogue access points.
The easiest way around a security policy is to find users who don't follow it. The Have I Been Pwned database identifies accounts with information breached by major third parties like Yahoo and LinkedIn. With Maltego, hackers can locate breached accounts created using company email addresses, potentially giving attackers access to a company account if the employee reuses a compromised password.
Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal. Due to the way hashes work, not all are created equal. Some are more vulnerable than others, and a little Python could be used to brute-force any weak hashes to get the passwords they were created from.
There are many tools out there for Wi-Fi hacking, but few are as integrated and well-rounded as Bettercap. Thanks to an impressively simple interface that works even over SSH, it's easy to access many of the most powerful Wi-Fi attacks available from anywhere. To capture handshakes from both attended and unattended Wi-Fi networks, we'll use two of Bettercap's modules to help us search for weak Wi-Fi passwords.
Leaked databases get passed around the internet and no one seems to notice. We've become desensitized to the data breaches that occur on a daily basis because it happens so frequently. Join me as I illustrate why reusing passwords across multiple websites is a truly awful practice — and compromise hundreds of social media accounts in the process.
This is second post in my series of posts for finding hacked accounts online. Please do read the part 1 of the post at http://null-byte.wonderhowto.com/how-to/find-hacked-accounts-online-part-1-0164611/
