Things that are supposed to make life easier for developers and users are often easy targets for exploitation by hackers. Like many situations in the tech world, there is usually a trade-off between convenience and security. One such trade-off is found in a system known as Distributed Ruby, which can be compromised easily with Metasploit.
The ability to stay organized and be resourceful with data gathered from recon is one of the things that separates the true hackers from the script kiddies. Metasploit contains a built-in database that allows for efficient storage of information and the ability to utilize that information to better understand the target, which ultimately leads to more successful exploitation.
How To: Exploring Kali Linux Alternatives: Getting Started with Pentoo for Advanced Software Installations
Kali Linux is probably the most well-known hacking distribution among penetration testers. However, there are alternative distros which offer versatility and advanced package management systems that are absolutely worth considering.
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.
When it comes to attacking devices on a network, you can't hit what you can't see. Nmap gives you the ability to explore any devices connected to a network, finding information like the operating system a device is running and which applications are listening on open ports. This information lets a hacker design an attack that perfectly suits the target environment.
For anyone wanting to keep information private, plain text is a format of the past. Instead, cheap, powerful encryption is widely available, but often not easy enough to use to attract widespread adoption. An exception to this rule is EncryptPad, an easy to use application that lets you encrypt text, photos, or archives with strong encryption using a password, keyfile, or both.
Users are often the weakest link when probing for vulnerabilities, and it's no surprise they can be easily fooled. One way to do this is called clickjacking. This type of attack tricks the victim into clicking something they didn't mean to click, something under the attacker's control. Burp Suite contains a useful tool called Clickbandit to generate a clickjacking attack automatically.
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.
ARP spoofing is an attack against an Ethernet or Wi-Fi network to get between the router and the target user. In an ARP spoofing attack, messages meant for the target are sent to the attacker instead, allowing the attacker to spy on, deny service to, or man-in-the-middle a target. One of the most popular tools for performing this attack is Ettercap, which comes preinstalled on Kali Linux.
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.
The Raspberry Pi Zero W and Pi 3 Model B+ include integrated Wi-Fi, Bluetooth Low Energy, and more than enough power to run Kali Linux. They sound like perfect all-in-one penetration testing devices, but the lack of support for monitor mode and packet injection usually meant buying a supported Wi-Fi adapter. Now, it's possible to use monitor mode on the built-in Wi-Fi chip with Nexmon.
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.
To hack a Wi-Fi network, you need your wireless card to support monitor mode and packet injection. Not all wireless cards can do this, but you can quickly test one you already own for compatibility, and you can verify that the chipset inside an adapter you're thinking of purchasing will work for Wi-Fi hacking.
Cross-site scripting can be one of the easiest vulnerabilities to discover, but to be successful with this type of attack, it is essential to learn how to get past filters. In the previous guide, we explored some ways to do this, such as abusing attributes and event handlers and tricking the application into accepting unusual characters. Now, let's take a look at more techniques used to defeat filters.
There is no shortage of defenses against cross-site scripting (XSS) since it is so prevalent on the web today. Filters are one of the most common implementations used to prevent this type of attack, usually configured as a blacklist of known bad expressions or based on regex evaluation. But there is hope with a wide variety of techniques that can be used to defeat these filters.
Cross-site scripting is one of the most common vulnerabilities found on the web today, with repercussions of this type of flaw ranging from harmless defacement to sensitive data exposure. Probing for XSS can be tedious and time-consuming for an attacker, but luckily there are tools available to make things a little easier, including Burp Suite, Wfuzz, and XSStrike.
Everyone from first responders to hotel cleaning staff use radios operating in the sub-megahertz range to communicate, often without even encoding the transmission. While encoding and encryption are increasingly used in radio communication, an RTL-SDR adapter and smartphone are all it takes to start listening in on radio conversations happening around you.

Encrypting payloads and encoding stagers are more effective against macOS than one might think. Plus, it's very easy to evade VirusTotal and macOS antivirus software using a few simple tricks.
Cracking the password for WPA2 networks has been roughly the same for many years, but a new attack requires less interaction and information than previous techniques and has the added advantage of being able to target access points with no one connected. This new attack against the PMKID uses Hashcat to crack WPA passwords and allows hackers to find networks with weak passwords more easily.
Hundreds of Windows 10, macOS, and Linux vulnerabilities are disclosed every single week, many of which elude mainstream attention. Most users aren't even aware that newly found exploits and vulnerabilities exist, nor that CVEs can be located by anyone in just a few clicks from a selection of websites online.
The ability to execute system commands via a vulnerable web application makes command injection a fruitful attack vector for any hacker. But while this type of vulnerability is highly prized, it can often take quite a bit of time to probe through an entire application to find these flaws. Luckily, there is a useful tool called Commix that can automate this process for us.
Apple's macOS operating system is just as vulnerable to attacks as any Windows 10 computer or Android smartphone. Hacker's can embed backdoors, evade antivirus with simple commands, and utilize USB flash drives to completely compromise a MacBook. In this always-updated guide, we'll outline dozens of macOS-specific attacks penetration testers should know about.
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.
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.
Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to sniff the air for packets from any device we want to track, turning on an LED when it's detected nearby.
The most common Wi-Fi jamming attacks leverage deauthentication and disassociation packets to attack networks. This allows a low-cost ESP8266-based device programmed in Arduino to detect and classify Wi-Fi denial-of-service attacks by lighting a different color LED for each type of packet. The pattern of these colors can also allow us to fingerprint the tool being used to attack the network.
The latest macOS security update tries to make parts of the operating system difficult for hackers to access. Let's take a closer look at how this new feature works and what we can do to spoof the origin of an application attempting to access protected data.
It only takes a few commands to manipulate a MacBook's secure HTTPS traffic and pluck login passwords out of the encrypted data. Let's take Facebook and Gmail hacking to the next level by intercepting Safari and Google Chrome web traffic in real time.
Smartphones and laptops are constantly sending Wi-Fi radio signals, and many of these signals can be used to track us. In this guide, we'll program a cheap IoT device in Arduino to create hundreds of fake networks with common names; This will cause nearby devices to reveal their real trackable MAC address, and it can even let an attacker take over the phone's data connection with no warning.
In the world of technology, there's often a trade-off between convenience and security. The Java Remote Method Invocation is a system where that trade-off is all too real. The ability for a program written in Java to communicate with another program remotely can greatly extend the usability of an app, but it can also open up critical vulnerabilities that allow it to be compromised by an attacker.
One of the things that sets a seasoned hacker apart from the script kiddies is the ability to effectively sneak past antivirus defenses when executing an attack. One way to do this is to use custom shellcode in an exploit. Not everyone is an expert at writing shellcode, but luckily there's an easy way to do this that is both quick and effective.
The newest version of macOS has arrived. While everyone's mind is being blown by Mojave's groundbreaking new Dark Mode, we'll be taking advantage of its insecure file permissions to establish a persistent backdoor with a self-destructing payload that leaves little evidence for forensics.
Most companies have services like employee login portals, internal-only subdomains, and test servers they would prefer to keep private. Red teams and white hat hackers can find these obscure and often vulnerable services using a tool designed to help protect users from fraudulent certificates.
Having an efficient workflow is an integral part of any craft, but it's especially important when it comes to probing apps for vulnerabilities. While Metasploit is considered the de facto standard when it comes to exploitation, it also contains modules for other activities, such as scanning. Case in point, WMAP, a web application scanner available for use from within the Metasploit framework.
The road to becoming a skilled white hat is paved with many milestones, one of those being learning how to perform a simple Nmap scan. A little further down that road lies more advanced scanning, along with utilizing a powerful feature of Nmap called the Nmap Scripting Engine. Even further down the road is learning how to modify and write scripts for NSE, which is what we'll be doing today.
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.
Hacking macOS: How to Perform Situational Awareness Attacks, Part 2 (Finding Files, History & USB Devices)
It's important to know whom you're dealing with after hacking your target's MacBook. Getting remote access is simple, but covertly gathering information about the user and their system can be a challenge.
Nmap is more powerful than you know. With a few scripts, we can extend its functionality beyond a simple port scanner and start to identify details about target servers sysadmins don't want us to know.
