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.
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.
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.
Reconnaissance is the phase of an attack where a red team or hacker designs a strategy based on the information they can learn about the target, as well as what the available attack surface looks like. These scans can take time to discover relationships, but Raccoon OSINT scanner coordinates multiple automated scans to produce invasively detailed reports on a target with a single command.
For anyone using open source information to conduct an investigation, a balance between powerful tools and privacy controls are a must. Buscador is a virtual machine packed full of useful OSINT tools and streamlined for online research. This program can easily be set up in VirtualBox, and once that's done, we'll walk you through some of the most useful tools included in it.
A simple security flaw can allow an attacker to gain a strong foothold with little effort on their part. When a web application permits remotely hosted files to be loaded without any validation, a whole can of worms is opened up, with consequences ranging from simple website defacement to full-on code execution. For this reason, RFI can be a promising path to obtaining a shell.
The first few minutes after gaining access to a MacBook are critical — but where do we begin? Using tools built into macOS, we can develop an in-depth understanding of running background processes, detect antivirus software, locate sensitive files, and fingerprint other devices on the network. All of this can be done without installing additional software or modifying any files.
One of the first steps in reconnaissance is determining the open ports on a system. Nmap is widely considered the undisputed king of port scanning, but certain situations call for different tools. Metasploit makes it easy to conduct port scanning from directly inside the framework, and we'll show you three types of port scans: TCP, SYN, and XMAS.
Kali Linux, by default, probably doesn't have everything you need to get you through day-to-day penetration testing with ease. With a few tips, tricks, and applications, we can quickly get started using Kali like a professional white hat.
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.
With just one line of Ruby code embedded into a fake PDF, a hacker can remotely control any Mac computer from anywhere in the world. Creating the command is the easy part, but getting the target to open the code is where a hacker will need to get creative.
Gmail conversations, Facebook private messages, and personal photos can all be viewed by a hacker who has backdoor access to a target's Mac. By livestreaming the desktop or exfiltrating screenshots, this information can be used for blackmail and targeted social engineering attacks to further compromise the mark.
It's always a good idea to know how an attack works at the very basic level. Manual techniques for exploitation often find holes that even the most sophisticated tool cannot. Sometimes, though, using one of these tools can make things so much easier, especially if one has a solid foundation of how it works. One such tool can help us perform a cross-site request forgery with minimal difficulty.
Web 2.0 technology has provided a convenient way to post videos online, keep up with old friends on social media, and even bank from the comfort of your web browser. But when applications are poorly designed or incorrectly configured, certain flaws can be exploited. One such flaw, known as CSRF, allows an attacker to use a legitimate user's session to execute unauthorized requests to the server.
After gaining access to a root account, the next order of business is using that power to do something more significant. If the user passwords on the system can be obtained and cracked, an attacker can use them to pivot to other machines if the login is the same across systems. There are two tried-and-true password cracking tools that can accomplish this: John the Ripper and Hashcat.
Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.
In most macOS hacks, a non-root terminal is used to create a backdoor into the device. A lot of damage can be done as a low-privileged user, but it has its limitations. Think twice before granting a file permission to execute — an attacker might be able to convert your harmless scripts into persistent root backdoors.
Locating and abusing files containing unsafe permissions is an easy and surefire way to elevate shell privileges on a backdoored macOS device. This time around, we'll be more aggressive and attempt to phish a user's login password by prompting a convincing popup message merely asking the target for their password.
MacOS isn't known as an ideal operating system for hacking without customization, but it includes native tools that allow easy control of the Wi-Fi radio for packet sniffing. Changing channels, scanning for access points, and even capturing packets all can be done from the command line. We'll use aliasing to set some simple commands for easy native packet capture on a macOS system.
Getting root is considered the Holy Grail in the world of Linux exploitation. Much like SYSTEM on Windows, the root account provides full administrative access to the operating system. Sometimes even a successful exploit will only give a low-level shell; In that case, a technique called privilege escalation can be used to gain access to more powerful accounts and completely own the system.
Using Netcat to backdoor a macOS device has its short-comings. If the compromised Mac goes to sleep, the Netcat background process will occasionally fail to terminate correctly; This leaves Netcat running infinitely in the background and the attacker with no new way into the device. As an alternative, we'll use the lesser-known Tcl shell which can handle abrupt backdoor disconnections.
There are nearly 100,000 unique onion service addresses online with over two million people using Tor every single day. Join me as I explore a small fraction of what the Tor network has to offer.
Net neutrality is dead and your internet service providers can collect all the data they want. While VPNs are a great way to protect some of that privacy, they're not perfect. There is another option, though, called Noisy, which was created by Itay Hury. It floods your ISP with so much random HTTP/DNS noise that your data is useless to anyone even if they do get it.
Due to weaknesses in the way Wi-Fi works, it's extremely easy to disrupt most Wi-Fi networks using tools that forge deauthentication packets. The ease with which these common tools can jam networks is only matched by how simple they are to detect for anyone listening for them. We'll use Wireshark to discover a Wi-Fi attack in progress and determine which tool the attacker is using.
Just like cash, bitcoin is used for everything from regular day-to-day business to criminal activities. However, unlike physical cash, the blockchain is permanent and immutable, which means anyone from a teen to the US government can follow every single transaction you make without you even knowing about it. However, there are ways to add layers of anonymity to your bitcoin transactions.
As Android bug bounty hunters and penetration testers, we need a properly configured environment to work in when testing exploits and looking for vulnerabilities. This could mean a virtual Android operating system or a dedicated network for capturing requests and performing man-in-the-middle attacks.
If you need to hack an Android device, try a remote administration tool. Known more familiarly as a RAT, there are open-source RATs that are barebones and exorbitantly priced RATs that are more polished. There are also low-cost and polished RATs that aren't intended to be RATs at all, such as Cerberus, an anti-theft solution available right on Google Play.
Wi-Fi devices are continually emitting "probe frames," calling out for nearby Wi-Fi networks to connect to. Beyond being a privacy risk, probe frames can also be used to track or take over the data connection of nearby devices. We'll explain how to see nearby devices emitting probe frames using Probequest and what can be done with this information.
