During our last adventure into the realm of format string exploitation, we learned how we can manipulate format specifiers to rewrite a program's memory with an arbitrary value. While that's all well and good, arbitrary values are boring. We want to gain full control over the values we write, and today we are going to learn how to do just that.
Your home has walls for privacy, but Wi-Fi signals passing through them and can be detected up to a mile away with a directional Wi-Fi antenna and a direct line of sight. An amazing amount of information can be learned from this data, including when residents come and go, the manufacturer of all nearby wireless devices, and what on the network is in use at any given time.
Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
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.
Hi, I am Robel, I am here to let you know about how to hack windows admin password with out Sam files, this requires physical access and any boot operating system...I used Kali 1.8 , if it doesn't work make sure you have shuted it down properlyor use backtrack.
Hello guys I am ROMEO 64 (sounds weird I guess but who cares. :D).. Alright....Ever wondered what happens when you login to your Facebook account?
Alright so last time I gave you a homework assignment. This week we're gonna look at my version of the UDP-Flooder.
Greetings all. Today I intend to append a new series to my mini-collection of posts. This series will consist of informative guides for the purpose of depicting certain aspects of the White Hat profession that I believe are of profound importance. Furthermore, I will keep this series simple for everyone to follow, regardless of your tech level. So without further ado, let's get right into it.
Greetings to all geeks, hackers, nerds, and explorers of Null Byte. Welcome to my brand new tutorial, "Using BASH for Computer Forensics". This tutorial will give you a look at how the computer programming language, Bash, can be used to find out details on apple devices for later use.
Hello, my fellow hackers. My name is cl0ck. I am a senior majoring in Computer Engineering with an emphasis is Security. I have been lurking the site for a while now reading and learning from the great minds that reside here. I, too, have some knowledge that I would like to share with all of you. This post actually comes from a personal problem I faced and had to find a solution for. Without further ado, here it is:
I found this article a while back and I found it underneath a bunch of junk. Anyway, it's a article on 9 notorious hacker including Walter O'Brien (You know the T.V. show Scorpion? Well that's him). Not to mention the weird names:
welcome back my masters , teachers and classmates , in this second part of this 0-day series we will learn the basic of fuzzing, and i bought some gift for nullbyte(a 0 day vuln that will be released today exclusively on null-byte) .
Hello everyone Today I will show a different way to exploit a windows machine with a reverse https payload..."wait...why https? Isn't tcp good anymore?"
Recently, I've been learning Ruby as a second scripting language. But one topic I never covered with the many lessons online were sockets. So I did some research and came up with a very simple client/server connection that sends a string over the socket.
Do you remember the last time we used BeEF? Well, now we get to use it again, but this time with MITMf! We are going to auto-inject the hooking script into every webpage the victim visits!
Now that we have control over a victim's browser, we need to use some attacks to maintain the connection, or even better: upload a shell.
Hello readers, and welcome to Null Byte. Before we start, for those of you who may not know me, my name is ghost_; I'm a relatively active member of our community and have been around for a while.
Get some tinfoil hats and make a time machine because we are about to go back to the 90s and learn about some phreaking.
Welcome back, my amateur hackers! Over the course of the next year, we will be developing our own zero-day exploits. In my first article in this series, I introduced you to buffer overflows, which are the source of some of the most lethal exploits, particularly the "remote code execution," so we are focusing our exploit development here on a buffer overflow.
Welcome back, my aspiring hackers! Those of you who use Windows in a LAN environment understand that Windows machines can share directories, files, printers, etc. using "shares." This protocol dates back to the 1980s when the then dominant computer firm, IBM, developed a way for computers to communicate over the LAN by just using computer names rather than MAC or IP addresses.
Greetings. This how-to on hacking Windows 7/8/10 etc. admin account passwords using Windows Magnifier is focused on adding, changing, or deleting an admin level account on a Windows 7/8/10 etc.
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 fledgling hackers! Awhile back, I demonstrated one of my favorite little tools, netcat, which enables us to create a connection between any two machines and transfer files or spawn a command shell for "owning" the system. Despite the beauty and elegance of this little tool, it has one major drawback—the transfers between the computers can be detected by security devices such as firewalls and an intrusion detection system (IDS).
Welcome back, my fledgling hackers! The database is the hacker's "pot-of-gold," as it contains information that is very valuable to both the business and the hacker. In this, the second of my series on hacking databases, we're on the "hunt" for Microsoft's SQL Server. Although far from the most commonly used database (Oracle hold's that title), Microsoft's SQL Server is very often found in small-to-medium sized businesses. Even a few big businesses use it.
Welcome back, my rookie hackers! Many newbie hackers focus upon the technical aspects of hacking and fail to give enough attention to social engineering. In fact, I would say that technical hacks should ONLY be attempted if social engineering attacks fail. Why bother spending hours or days trying to hack a password if someone will simply give it to you?
Welcome, my neophyte hackers!
When I left off on our last hack, we had hacked into the ubiquitous Windows Server 2003 server by adding ourselves as a user to that system so that we can return undetected at any time. The problem with this approach is that a sysadmin who is on their toes will note that a new user has been added and will begin to take preventative action.
Welcome back, hacker novitiates! In the next few hacks, we will be breaking into Windows servers. In this installment, we will learn to add ourselves as a user to a Windows 2003 server. Of course, when we have added ourselves as a user, we can come back any time and simply log into our account without having to hack into the system and risk detection.
With millions of people working from home as a result of the coronavirus outbreak, hacking is on the rise. Nefarious black hats are taking advantage of the fact that workers have been forced to abandon their secure office networks in favor of home wireless connections. And white hats are spending even more time at home trying to be the next great ethical hacker.
While we haven't covered Amazon Web Services, or AWS, on Null Byte before, Amazon's cloud computing platform is ripe for attack by hackers, pentesters, and cybersecurity researchers. It's also an excellent cloud hosting service to build or use vulnerable-by-design AWS setups and frameworks.
Phone numbers often contain clues to the owner's identity and can bring up a lot of data during an OSINT investigation. Starting with a phone number, we can search through a large number of online databases with only a few clicks to discover information about a phone number. It can include the carrier, the owner's name and address, and even connected online accounts.
With the number of web applications out there today, it comes as no surprise that there are just as many vulnerabilities waiting for hackers to discover. Finding those vulnerabilities can be a difficult task, but there are plenty of tools available to make the process easier. While it won't help find any zero-days, web scanners such as Uniscan will detect common vulnerabilities.
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.
Most users don't realize how much valuable data is in their network traffic. With a few simple tools, an attacker can quickly pick out cookies, passwords, and DNS queries from a macOS device as it covertly streams the victim's network traffic to the attacker's system. Here, we will cover two methods for analyzing packets flowing from a Mac.
While there are a variety of privacy-focused search engines available like StartPage and DuckDuckGo, nothing can offer the complete trust offered by creating one's own search engine. For complete trust and security, Searx can be used as free metasearch engine which can be hosted locally and index results from over 70 different search engines.
Web applications are becoming more and more popular, replacing traditional desktop programs at an accelerated rate. With all these new apps out on the web comes various security implications associated with being connected to the internet where anyone can poke and prod at them. One of the simplest, yet the most prevalent types of security flaws found in modern web apps are SQL injections.
WordPress did not become what is arguably the most popular blogging and CMS platform on the planet because it was difficult to use. Rather, its user-friendly and rich feature set led to it finding a home on somewhere north of 70 million websites—and that's just counting blogs hosted on WordPress.com.
Most of you lot would be aware what WPA/WPA2 is so I won't bang on about the encryption or protocols a great deal. In short WPA and WPA2 both have a maximum of 256bit encrypted with a maximum of 64 characters in the password. The encryption is really only 64bit but x 4 because of the way the authentication functions as a 4 way handshake.
Hello friends. This is actually my first how to.
