Watch this how to video to learn more about picking fresh food and the preservation process.
Facebook's annual earnings call on Wednesday didn't come with any big surprises, that is, if you took everything at face value.
Post-exploitation is often not quite as exciting as popping the initial shell, but it's a crucial phase for gathering data and further privilege escalation. Once a target is compromised, there's a lot of information to find and sift through. Luckily, there are tools available that can make the process easy. One such tool is Postenum.
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.
Using a strong password is critical to the security of your online accounts. However, according to Dashlane, US users hold an average of 130 different accounts. Memorizing strong passwords for that many accounts is impractical. Fortunately, password managers solve the problem.
As fun as Twitter is, it can also quickly turn scary. Anonymous, aggressive, and troll accounts can attack you for your tweets and stalk your every move. While you could make your profile private and block users, there are lesser-known privacy and security features that you can switch to improve your safety online.
UnrealIRCd is an open-source IRC server that has been around since 1999 and is perhaps the most widely used one today. Version 3.2.8.1 was vulnerable to remote code execution due to a backdoor in the software. Today, we will be exploiting the vulnerability with Metasploit, examining the underlying code to understand it, and creating our own version of the exploit in Python.
Post-exploitation information gathering can be a long and drawn-out process, but it is an essential step when trying to pivot or establish advanced persistence. Every hacker should know how to enumerate a target manually, but sometimes it is worth it to automate the process. Metasploit contains post modules that can quickly gather valuable information about a target, saving both time and effort.
They're finally here. Apple revealed the brand new iPhone 11, 11 Pro, and 11 Pro Max on Sept. 10, and despite the questionable names, these are the best iPhone models money can buy. If you're looking to get your hands on one of these devices as soon as possible, there are few important dates you need to know.
UAC is something we've all dealt with on Windows, either as a user, administrator, or attacker. It's a core feature of the Windows security model, and for the most part, it does what it's supposed to. But it can be frustrating as a hacker when attempting privilege escalation, but it's easy enough to bypass UAC and obtain System access with Metasploit.
EternalBlue was a devastating exploit that targeted Microsoft's implementation of the SMB protocol. Metasploit contains a useful module that will automatically exploit a target, as long as it's vulnerable. But what if we wanted to exploit this vulnerability without Metasploit holding our hand? It can be done using a Python file to exploit EternalBlue manually.
It feels strange to be walking through an open field in a small village in the English countryside. There's no one else around — just the four of us: me, my husband, my 12-year-old son, and my adult niece. The day is spectacular, particularly for England. The sun is shining, and the temperature is in the low '70s.
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.
Before attacking any website, a hacker or penetration tester will first compile a list of target surfaces. After they've used some good recon and found the right places to point their scope at, they'll use a web server scanning tool such as Nikto for hunting down vulnerabilities that could be potential attack vectors.
With the number of web applications out there today, it comes as no surprise that there are just as many vulnerabilities waiting for hackers to discover. Finding those vulnerabilities can be a difficult task, but there are plenty of tools available to make the process easier. While it won't help find any zero-days, web scanners such as Uniscan will detect common vulnerabilities.
The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.
Many popular IoT devices have terrible security. For instance, a hacker who's on the same Wi-Fi network as a Sonos speaker can assume direct control over the device's behavior. If an IoT device doesn't secure the messages used to control it over a network, it's easy for somebody to write a few Python scripts to make it do whatever they want.
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.
Computers all over the world rely on a program called "libssh" to use the SSH communications protocol, which allows trusted users to log in and administer computers remotely. Due to a flaw in libssh, fooling a computer into granting SSH access is as easy as telling it you already have permission. The vulnerability can lead to an attacker gaining complete control over a device.
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.
The holiday season is upon us, and that means all the big-box stores are competing against each other to offer the best prices on electronics. What was once a 24-hour period of flash deals the day after Thanksgiving has now become a holiday in and of itself — Black Friday is an event you don't want to miss.
One of the best ways to improve your skills as a hacker is to learn to combine different avenues of attack to achieve success. What if it were possible to get a victim to connect to our machine and execute a chosen payload on our behalf? This is indeed possible with the almighty Metasploit and the aid of a technique known as command injection.
The macOS 10.14 security update tried to make parts of the operating system difficult for hackers to access. Let's take a closer look at how its new feature works and what we can do to spoof the origin of an application attempting to access protected data.
It's not uncommon for hackers to attempt to move laterally between devices in proximity of a compromised device to maintain a prolonged presence in the network. Malware utilizing USB flash sticks to self-replicate and compromise air-gapped machines isn't a new concept.
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.
If you're on the hunt for a profitable side-gig, or even a completely new way to to make money, you'll want to take a look at Upwork, a leading freelancing platform that connects skilled freelancers with clients from all over the world.
The misconception that macOS is more secure than the Windows operating system is far from the truth. With just one small command, a hacker can completely take over a MacBook and control it remotely.
Using a keylogger to intercept keys pressed on an infected computer can circumvent encryption used by email and secure chat clients. The collected data can often reveal usernames, passwords, and potentially compromising and private information which hackers abuse for financial gain.
With Gboard, Google created a keyboard with more functionality than just inputting words. The app includes features such as GIF search and live text translation, but it gets even better when you let it learn more about you. With this data, Gboard grows from a good keyboard to one that can complete your sentences.
Ports allow network and internet-connected devices to interact using specified channels. While servers with dedicated IP addresses can connect directly to the internet and make ports publicly available, a system behind a router on a local network may not be open to the rest of the web. To overcome the issue, port forwarding can be used to make these devices publicly accessible.
The internet is constantly under siege by bots searching for vulnerabilities to attack and exploit. While conventional wisdom is to prevent these attacks, there are ways to deliberately lure hackers into a trap in order to spy on them, study their behavior, and capture samples of malware. In this tutorial, we'll be creating a Cowrie honeypot, an alluring target to attract and trap hackers.
