Proxies can be quicker to use than a VPN for specific applications, like web browsers or torrent clients. Both services will hide your true IP address, but a VPN is slowed down because it encrypts all data through a VPN network, while a proxy just acts as a middleman for fetching and returning requests from a server on your behalf. When speed is needed, go proxy.
Facebook really wants your phone number, nagging you to connect one as soon as you join. This isn't all bad, since it can be useful in securing your account with two-factor authentication. On the flipside, this makes it easy to reveal the private phone numbers of virtually anyone on Facebook, including celebrities and politicians. Today we're going to look at how a hacker would do this, and how to protect yourself.
Hacking Pranks: How to Flip Photos, Change Images & Inject Messages into Friends' Browsers on Your Wi-Fi Network
Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing us to intercept and modify network data. This can be dangerous for private data, but also be fun for pranking your friends.
Steganography is the art of hiding information in plain sight, and in this tutorial, I'll show you how to use Steghide — a very simple command line tool to do just that. In addition, I'll go over a bit of conceptual background to help you understand what's going on behind the scenes. This is a tool that's simple, configurable, and only takes a few seconds to hide information in many file types.
There are more than 2 billion Android devices active each month, any of which can be hacked with the use of a remote administration tool, more commonly known as a RAT. AhMyth, one of these powerful tools, can help outsiders monitor a device's location, see SMS messages, take camera snapshots, and even record with the microphone without the user knowing.
Internet Relay Chat, or IRC, is one of the most popular chat protocols on the internet. This technology can be connected to the Tor network in order to create an anonymous and secure chatroom, without the use of public IP addresses.
So much information exists online that it's easy to get lost in data while researching. Understanding the bigger picture can take a lot of time and energy, but narrowing the question to one that's easy to answer is the first step of any investigation. That's why analysts use open-source intelligence (OSINT) tools like Maltego — to help refine raw data into a complete understanding of a situation.
After exploiting a vulnerable target, scooping up a victim's credentials is a high priority for hackers, since most people reuse passwords. Those credentials can get hackers deeper into a network or other accounts, but digging through the system by hand to find them is difficult. A missed stored password could mean missing a big opportunity. But the process can largely be automated with LaZagne.
The default tool for payload generation is MSFvenom, a Metasploit standalone payload generator as well as encoder. This tool is an incredibly powerful tool for payload generation, but it can be difficult and requires a bit of reading for newer users.
In a previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when a Microsoft Word document is opened. The biggest challenge of this attack is that it requires getting the user to agree to a pop-up prompt. Fortunately, since I posted that article, many new obfuscation techniques have been discovered to make this easier. Today, we explore and combine some of them to make the ultimate hidden DDE attack.
While hackers adore the command line, working with the GUI (graphical user interface) of an operating system has some advantages. This is especially true when it comes to post-exploitation. When we can control the mouse and keyboard of a remote computer, we can truly say we have complete control over the device. Today, I'm going to introduce to you the PyAutoGUI module, which does just that, and just how much fun you can have with it!
Hak5's products get a lot of attention. Popping up in popular shows like Mr. Robot, their hacking tools are bold proof of concepts with space built into the design for the community to add their own tweaks and modifications. On Friday, Oct. 27, Null Byte attended the Hak5 release event in San Francisco to check out their latest devices, including the new Packet Squirrel.
In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.
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.
When hacking Wi-Fi networks, having the right wireless adapter is essential. But hunting online for one can be a frustrating experience. To see how the handful of Kali-compatible adapters on the market measure up, I ran a series of tests to benchmark and compare their range, signal strength, and ability to enter monitor mode and perform packet injection. This should help you determine which adapter is right for your own hacking needs.
A mention of the deep web can bring to mind images of drugs, hackers, and other criminal activity. Despite the presence of these elements, the Tor network is a valuable tool for preserving privacy and anonymity. Browsing the deep web and any hidden services can be as simple as downloading the Tor Browser Bundle. In this guide, we will learn how easy it is to host our own hidden services and make them accessible via a custom onion address.
The Watch Dogs video game series came out in 2014, enamoring audiences with the idea of a seemingly magical smartphone that could change traffic signals, hack web cameras, and even remotely control forklifts. This may sound like science fiction, but The Sonic uses a customized flavor of Kali Linux to allow you to unleash the power of Kali from any smartphone — all without the need to create a hotspot to control it.
In October of 2017, Mathy Vanhoef released "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2." This paper demonstrates a way to decrypt traffic on practically any WPA2 network, the most commonly used form of wireless security (seeing as all other forms of Wi-Fi encryption have already been broken). Practically all of the network-connected devices we use will need to be updated in some way in order to protect against this vulnerability, each of them in a different way.
Some of us woke up at the KRACK of dawn to begin reading about the latest serious vulnerability that impacts the vast majority of users on Wi-Fi. If you weren't one of those early readers, I'm talking about the Key Reinstallation Attack, which affects nearly all Wi-Fi devices.
When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.
If you need to scan a large number of domains for a specific web app vulnerability, Dorkbot may be the tool for you. Dorkbot uses search engines to locate dorks and then scan potentially vulnerable apps with a scanner module.
Armis Labs has revealed eight vulnerabilities, called "BlueBorne", which put 5.3 billion Android, iOS, Windows, and Linux devices that use Bluetooth at risk. With it, hackers can control devices, access data, and spread malware to other vulnerable devices through networks. In this post, we will learn about the vulnerabilities, then look at how to find devices that have them.
Code execution in Microsoft Word is easier than ever, thanks to recent research done by Etienne Stalmans and Saif El-Sherei. Executing code in MS Word can be complicated, in some cases requiring the use of Macros or memory corruption. Fortunately, Microsoft has a built in a feature that we can abuse to have the same effect. The best part, it does so without raising any User Account Control security warnings. Let's look at how it's done.
This weeks' article on Pupy made me wish for a RAT that could be targeted at an OS frequently used by gatekeepers at startups, tech companies, and creative firms: macOS. Once run, a RAT can do particularly severe damage by dumping a user's stored credentials for many accounts. The best loot lives in the Chrome Password cache, so today we'll be using EvilOSX, an OS X RAT, to infiltrate macOS and dump these credentials.
Surveillance is always a useful tool in a hacker's arsenal, whether deployed offensively or defensively. Watching targets yourself isn't always practical, and traditional surveillance camera systems can be costly, lacking in capabilities, or both. Today, we will use motionEyeOS running on a Raspberry Pi Zero to create a small, concealable Wi-Fi connected spy camera that is both affordable and easily concealed.
In one of my previous articles, I discussed ShinoBot, a remote administration tool that makes itself obvious. The goal is to see if the user could detect a remote administration tool or RAT on their system. In this article, I'll be demonstrating the use of Pupy, an actual RAT, on a target Ubuntu 16.04 server.
Tor is an excellent obfuscation network for web traffic, and while instant messaging over the network is very useful, it can be relatively difficult to configure. In this guide, we'll look at two synchronous communications platforms (instant messengers) which can be routed over the Tor network, Ricochet and XMPP.
When hacking into a network during a penetration test, it can sometimes be useful to create your own wireless AP simply by plugging a Pi into an available Ethernet port. With this setup, you have your own backdoor wireless connection to the network in a matter of seconds. Creating an AP is also helpful while traveling, or needing to share a connection with a group of people.
Bluetooth Low Energy (BLE) is the de facto wireless protocol choice by many wearables developers, and much of the emerging internet of things (IoT) market. Thanks to it's near ubiquity in modern smartphones, tablets, and computers, BLE represents a large and frequently insecure attack surface. This surface can now be mapped with the use of Blue Hydra.
Hacking from a host machine without any form of proxying is reckless for a hacker, and in a penetration test, could lead to an important IP address becoming quickly blacklisted by the target. By routing all traffic over Tor and reducing the threat of malicious entrance and exit nodes with a VPN, we can configure Kali to become thoroughly private and anonymous.
Null Byte users have often requested video content, but the question has always been what format would best serve our community. This week, we partnered with Null Space Labs, a hackerspace in Los Angeles, to test the waters by hosting a series of talks on ethical hacking for students in Pasadena Computer Science Club. We invited students and Null Byte writers to deliver talks on Wi-Fi hacking, MITM attacks, and rogue devices like the USB Rubber Ducky.
Virtual private networks, or VPNs, are popular for helping you stay anonymous online by changing your IP address, encrypting traffic, and hiding your location. However, common IoT devices, media players, and smart TVs are hard to connect to a VPN, but we have a solution: Turn a Raspberry Pi into a router running through PIA VPN, which will ensure every connected device gets the VPN treatment.
How To: Exploring Kali Linux Alternatives: How to Get Started with Parrot Security OS, a Modern Pentesting Distro
Kali Linux is the obvious first choice of 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 there are many exciting alternatives that may better fit your use-case. In my previous article, I looked at BlackArch Linux. In this article, I'll talk about Parrot Security OS.
During a penetration test, one of the most important aspects of engaging a target is information gathering. The more information you have coming into an attack, the more likely the attack is to succeed. In this article, I'll be looking at SpiderFoot, a modular cross-platform OSINT (open-source intelligence) gathering tool.
How To: Exploring Kali Linux Alternatives: How to Get Started with BlackArch, a More Up-to-Date Pentesting Distro
In 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied together with the Gnome desktop environment. However, Kali Linux isn't the only penetration-testing distribution available.
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.
Every time you make a call or send a text, you're giving the recipient your phone number. This can be quite the security vulnerability, opening yourself up to scammers, spammers, and the feds. In this how-to, we'll look at what a burner phone is, why you might want one, and how to get started using a free second phone number on your regular smartphone.
Equifax reported on Sept. 7 that it discovered a breach on July 29 which affects roughly half of Americans, many of whom don't realize they have dealings with the company. Hackers got away with social security numbers, addresses, and driver's license numbers, foreshadowing a "nuclear explosion of identity theft." Let's explore what really happened and what you and those around you can do to protect yourselves.
A PirateBox creates a network that allows users to communicate wirelessly, connecting smartphones and laptops even when surrounding infrastructure has been disabled on purpose or destroyed in a disaster. Using a Raspberry Pi, we will make a wireless offline server that hosts files and a chat room. Among other applications, this PirateBox can be used as an educational database, a discreet local chat room, or a dead-drop file server.
