A rainbow table can be thought of like a dictionary, except instead of words and their definitions, it holds combinations of characters on one side and their hashed form on the other. What is a hash and why would you want to know what random combinations of characters are hashed into?
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.
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.
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.
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.
As we enter the second half of 2018, rumors for the second season of flagships have started to emerge. On the Android side, this means the latest iterations of the Google Pixel, Galaxy Note, LG V series, and Huawei Mate. Thanks to FunkyHuawei and XDA, we now have some solid rumors regarding the Huawei Mate 20.
One of the most critical bugs to come out in the last five years was Shellshock, a vulnerability which allows attackers to execute arbitrary code via the Unix Bash shell remotely. This vulnerability has been around for a while now, but due to the ubiquity of Unix machines connected to the web, Shellshock is still a very real threat, especially for unpatched systems.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Every once in a while, we find ourselves in a predicament where we need an inexpensive smartphone. Whether we're finally upgrading from that feature phone we held onto too long or we dropped our current smartphone, sometimes we need a quick replacement to get back on track. That's where Android One comes in.
Hackers rely on good data to be able to pull off an attack, and reconnaissance is the stage of the hack in which they must learn as much as they can to devise a plan of action. Technical details are a critical component of this picture, and with OSINT tools like Maltego, a single domain name is everything you need to fingerprint the tech details of an organization from IP address to AS number.
Apple has introduced a special edition iPhone 8 and 8 Plus to bring attention to the ongoing worldwide battle against AIDS. As the second iPhones to carry the (PRODUCT)RED name, these rare iPhones may quickly sell out when preorders open up on Tuesday, April 10, at 5:30 a.m. (PDT), so we'll go over some tips to help you secure a red iPhone before it's gone.
It's easy to have your password stolen. Important people like executives, government workers, journalists, and activists face sophisticated phishing attacks to compromise their online accounts, often targeting Google account credentials. To reduce this risk, Google created the Advanced Protection Program, which uses U2F security keys to control account access and make stolen passwords worthless.
For years, PuTTy has reigned supreme as the way to establish a Secure Shell (SSH) connection. However, those days are numbered with the addition of the OpenSSH server and client in the Windows 10 Fall Creators Update, which brings Windows up to par with macOS and Linux's ability to use SSH natively.
The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.
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.
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.
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.
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.
In my previous article, I discussed installing and configuring OpenVAS on Kali Linux. Now it's time to start using OpenVAS with the Greenbone Security Assistant to audit networks for security issues. This can be extremely helpful when you are looking for vulnerabilities or misconfigurations in a large number of hosts.
If you need a tiny, flexible attack platform for raining down human-interface-device (HID) attacks on unattended computers, the USB Rubber Ducky is the most popular tool for the job. By loading the Ducky with custom firmware, you can design new attacks to be effective against even air-gapped computers without internet access. Today, you'll learn to write a payload to make "involuntary backups" through copying a targeted folder to the Ducky's USB mass storage.
In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
Augmented and mixed reality developer Arvizio is working on a suite of software solutions for enterprises that will extend HoloLens capabilities as a full-fledged collaboration and conferencing tool. The company will demonstrate its Mixed Reality Studio suite to attendees at the Augmented World Expo, which begins later this month in Santa Clara, California.
Apple just unveiled a red iPhone and iPhone 7 Plus, dubbed the iPhone 7 (PRODUCT)RED Special Edition, to commemorate the ongoing global fight against AIDS. Apple fans the world over are sure to swarm in and gobble up the initial stock shortly after the new color is released at 8:01 a.m. (PDT) on March 24, 2017, so we'll go over some tips to help you secure a red iPhone before it's sold out.
Long before Apple and Android became household names, Nokia dominated the mobile industry. The Finnish company was one of the first to develop smartphones, and their classic N95 with 2G "high-speed" internet connectivity was declared the "best smartphone ever" by some in 2007. Outside of the US, before the iPhone became all the rage, owning a Nokia phone was a status symbol akin to wearing a Rolex or Omega watch.
The newest version of Apple's mobile operating system, iOS 10, has been out for about a month now. But like every year beforehand, some of you who updated will not be happy with the latest and "greatest" iOS version.
Hello null byte!! I found a local local privilege escalation exploit on Exploit-db known as CVE-2015-5889: issetugid() + rsh + libmalloc osx local root by rebel. You can visit the link here or find the code on pastebin here.
Windows users have looked on with envy at Mac owners wrangling torrents with ease for years. Now, finally, a new Windows torrent client is making downloads easier, safer, and more customizable.
Welcome back, my tenderfoot hackers! As you should know from before, Snort is the most widely deployed intrusion detection system (IDS) in the world, and every hacker and IT security professional should be familiar with it. Hackers need to understand it for evasion, and IT security professionals to prevent intrusions. So a basic understanding of this ubiquitous IDS is crucial.
Hello NullByte, it's mkilic! This time I'm here with the C.H.I.P from NTC. Although it is not too popular, the C.H.I.P is a brand new micro computer. It is very similar to the Raspberry Pi or Beaglebone Black. The key difference with this particular board is its cost and size. The C.H.I.P only costs $9 and measures 2.5 x 1.5 inches. In addition to this, the C.H.I.P has built in 802.11 b/g/n Wifi and Bluetooth 4.0. Considering these great specs, what could a Hacker use this for? Step 1: The In...
There's been a whole lot going on at this year's Consumer Electronics Show, from the latest in virtual reality gear to televisions that continue to slim down while producing higher quality images.
Considering that nearly half a million brand new apps were published to the Google Play Store in 2015, you can definitely call it a banner year for Android development. In fact, it's getting to the point where we're a bit spoiled as end users, since we've grown to expect something new and exciting practically every week.
Welcome finally, to a tutorial on buffer overflows! At last we have reached an exciting part of this series where I will dedicate the entire article on explaining and exploiting the notorious vulnerability. Grab some popcorn, sit back and enjoy the show.
Welcome back to control structures, part two featuring the three types of loops. Here we go! What Is a Loop?
Welcome back, my greenhorn hackers!
At a closed-door presentation on September 30th, 2014, Microsoft unveiled the latest iteration of its industry-leading operating system. Dubbed Windows 10 (seems as if Redmond isn't too fond of the "9" moniker), this new version brings along with it many UI optimizations and under-the-hood tweaks. With a particular focus on optimizing the interface for traditional mouse and keyboard computers, one of the most noticeable changes is the return of the Start Menu. While touch-optimized devices wi...
Welcome back, my hacker novitiates! Every so often, a MAJOR vulnerability appears that makes millions of systems vulnerable to attack. The most recent, named Shellshock, basically leaves every Mac OS X, Linux, and UNIX system on the planet vulnerable. As nearly two-thirds of all web servers on planet Earth run one of these operating systems (primarily Linux), that's a whole lot of systems out there waiting to be harvested.
Telemarketers can be as terrifying as a villain from a horror film. Your phone rings with an unknown 800 number, and you immediately fill with a sense of dread. There's no way to get them to stop calling; you imagine the number appearing on your phone at all hours of the day and night, haunting you.
Welcome back, my fledgling hackers! Scripting skills are essential is ascending to the upper echelons of the hacker clique. Without scripting skills, you are dependent upon others to develop your tools. When others develop your tools, you will always be behind the curve in the battle against security admins.
Welcome back, my apprentice hackers! As many of you know, I have been hesitant to adopt the new Kali hacking system from Offensive Security. This hesitancy has been based upon a number of bugs in the original release back in March of 2013 and my belief that BackTrack was easier for the novice to work with.
Apple released iOS 7.0.6 last week, an update to fix a serious security flaw that allowed hackers to not only capture sensitive user information such as bank statements and passwords, but also modify that same data on secure HTTPS sessions.
