Although there has been much speculation about how much damage could be done if hackers were to take control of a country's SCADA systems, there have been few examples - until a few months ago, with the power outage in Ukraine caused by hackers.
What's up guys? Welcome to a sort of general walkthrough on how one might approach a reversing and analysis on a crypted malware. This is by no means a universal technique so don't assume that this will occur in every scenario, it's more of a demonstration than anything really.
I mentioned in 2015 I wanted to start a 'DoXing' series, and since I havent seen this on Null Byte, I am now going to introduce this to the community.
In part one of this tutorial we found out that your English teacher is a paedophile, by using a Man in the Middle attack to intercept his internet traffic.
Why did I write this when they're tons of scanning tools available.
Welcome back, my greenhorn hackers! Earlier in this series, I showed a you a couple of different ways of fingerprinting webservers. Probably the easiest way, is to use netcat and connect to port 80 and pull the webserver banner.
Welcome back, my novice hackers! In a recent tutorial, I showed how the SNMP protocol can be a gold mine of information for reconnaissance on a potential target. If you haven't already, I strongly suggest that you read it before progressing here, as little of this will make much sense without that background.
SSH, or the secure shell, is a way of controlling a computer remotely from a command-line interface. While the information exchanged in the SSH session is encrypted, it's easy to spy on an SSH session if you have access to the computer that's being logged in to. Using a tool called SSHPry, we can spy on and inject commands into the SSH sessions of any other user logged in to on the same machine.
Welcome back, my newbie hackers! We've already saved the world from nuclear annihilation and covered our tracks afterwards, but the world is still threatened by a malicious, megalomaniacal dictator with missiles and nuclear weapons.
Reconnaissance is one of the most important and often the most time consuming, part of planning an attack against a target.
Recently, I ran across SecGen, a project which allows a user to create random vulnerable machines. I absolutely love vulnerable machines, since a vulnerable VM is a safe and legal way to practice hacking tactics, test out new tools, and exercise your puzzle-solving skills.
Hello dear friends! I'm jgilhutton and I want to show you guys a Python wrapper I made a few months ago.
In my last hack blog on crashing your roommates Win7 system, we started looking at client- side attacks. As promised, we will be looking at some more client-side attacks.
The increasingly important world of white hat or "ethical" hacking is getting competitive. Thanks to growing salaries and opportunities for talented and trained coding pros who can infiltrate servers and safeguard networks against digital threats, demand for intrepid cyber warriors is through the roof, and it shows no signs of slowing down any time soon.
While many people may use Bluetooth every day, the majority don't know how it works or that it can be hacked. Bluetooth hacking gives a clear window into the world of the target. Nearly every device has Bluetooth capabilities, and people store a great deal of personal info on their phones and tablets. Hack their Bluetooth connection, and you may be able to access all of that data.
Samba can be configured to allow any user with write access the ability to create a link to the root filesystem. Once an attacker has this level of access, it's only a matter of time before the system gets owned. Although this configuration isn't that common in the wild, it does happen, and Metasploit has a module to easily exploit this security flaw.
Correctly identifying the underlying technologies that run on a website gives pentesters a considerable advantage when preparing an attack. Whether you're testing out the defenses of a large corporation or playing the latest CTF, figuring out what technologies a site uses is a crucial pen-tester skill.
Automating port scanners, directory crawlers, and reconnaissance tools can be complicated for beginners just getting started with Kali Linux. Sparta solves this problem with an easy-to-use graphical interface designed to simplify a penetration tester's tasks.
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.
Using just a small sticky note, we can trigger a chain of events that ultimately results in complete access to someone's entire digital and personal life.
Tossing an old Android smartphone with a decent battery into your hacking kit can let you quickly map hundreds of vulnerable networks in your area just by walking or driving by them. The practice of wardriving uses a Wi-Fi network card and GPS receiver to stealthily discover and record the location and settings of any nearby routers, and your phone allows you to easily discover those with security issues.
Open-source data scraping is an essential reconnaissance tool for government agencies and hackers alike, with big data turning our digital fingerprints into giant neon signs. The problem is no longer whether the right data exists, it's filtering it down to the exact answer you want. TheHarvester is a Python email scraper which does just that by searching open-source data for target email addresses.
Hello partners, first of all I would like to thank all those who have sent me positive feedback about my posts, to say that I'm always willing to learn and teach. I'm also open to answer the appropriate questions.
Welcome back, my tenderfoot hackers! Recently, Microsoft released a new patch (September 8, 2015) to close another vulnerability in their Windows Vista, 7, 8, and 8.1 operating systems. The vulnerability in question (MS15-100) enabled an attacker to gain remote access to any of these systems using a well-crafted Media Center link (MCL) file.
Welcome back, my novice hackers! Before we try to attack a website, it's worthwhile understanding the structure, directories, and files that the website uses. In this way, we can begin to map an attack strategy that will be most effective.
Welcome back, my rookie hackers! The more we know about a system or network, the better our chances of owning it and not leaving a trace for investigators to follow. One of the often overlooked sources for information is the Simple Network Management Protocol (SNMP). Many rookie hackers are not even aware of it, but it can prove to be a treasure trove of information, if you understand how it works and how to hack it.
Welcome back, my budding hackers! I've written several listener guides on creating a malicious PDF or malicious Word document that would carry in it a payload with the Meterpreter, or reverse shell enabling you to own the system. One of the hurdles to using these techniques is the antivirus (AV) software on the target system. For instance, if you try to email a malicious PDF or Word doc, it's likely that the victim system will alert the victim that it contains a virus or other malware.
Welcome back, my nascent hackers! Earlier, I wrote a guide on finding operating system and application vulnerabilities in Microsoft's own security bulletins/vulnerability database. In this tutorial, I will demonstrate another invaluable resource for finding vulnerabilities and exploits by using the SecurityFocus database.
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.
The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, broadcast an FM radio signal, and apparently even fly a goddamn missile into a helicopter.
Businesses leave paper trails for nearly every activity they do, making it easy for a hacker or researcher to dig up everything from business licenses to a CEO's signature if they know where to look. To do this, we'll dig into the databases of government organizations and private companies to learn everything we can about businesses and the people behind them.
With a tiny computer, hackers can see every website you visit, exploit services on the network, and break into your Wi-Fi router's gateway to manipulate sensitive settings. These attacks can be performed from anywhere once the attacker's computer has been connected to the router via a network implant.
Firewall solutions for macOS aren't impervious to attacks. By taking advantage of web browser dependencies already whitelisted by the firewall, an attacker can exfiltrate data or remotely control a MacBook, iMac, Mac mini, or another computer running macOS (previously known as Mac OS X).
Complex shell scripts can be implanted into photo metadata and later used to exploit a MacBook. In addition to obfuscating the true nature of an attack, this technique can be used to evade network firewalls as well as vigilant sysadmins.
In my previous article, we learned how to generate a vulnerable virtual machine using SecGen to safely and legally practice hacking. In this tutorial, we will put it all together, and learn how to actually hack our practice VM. This will provide some insight into the methodology behind an actual attack and demonstrate the proper way to practice on a VM.
While the USB Rubber Ducky is well known by hackers as a tool for quick in-person keystroke injection attacks, one of the original uses for it was automation. In this guide, I'll be going the latter, explaining how we can use it to automate Wi-Fi handshake harvesting on the Raspberry Pi without using a screen or any other input.
Welcome back, my aspiring hackers! In many of my earlier tutorials, I mentioned the complementary nature of hacking and forensics. Both disciplines, hacking and forensics, benefit from a knowledge of the other. In many cases, both disciplines will use the same tool. In this tutorial, we will use another tool that can be used in either discipline—Sysinternals—a suite of tools developed by Mark Russinovich.
Welcome back, my greenhorn hackers! In previous Wi-Fi hacking tutorials, I have shown you ways to create an Evil Twin, to DoS a wireless AP, and to crack WEP and WPA2 passwords, but in this tutorial, I will show you something a little bit different.
Choosing which programming language to learn next can be a truly daunting task. That's the case regardless of whether you're a Null Byter just beginning a career in development and cybersecurity or you're a seasoned ethical hacking and penetration tester with years of extensive coding experience under your belt. On that note, we recommend Python for anyone who hasn't mastered it yet.
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.
