Hack Like a Pro: Networking Basics for the Aspiring Hacker, Part 2 (TCP/IP)
Welcome back, my greenhorn hackers!
Welcome back, my greenhorn hackers!
When performing something such as a mass mailer attack on a company, sending executables usually isn't the best option. That's why, in this tutorial, I'll be teaching you how to code a VBA script macro into a Word document in order to compromise a system. Combined with a little social engineering, this can be a very effective technique.
Hey guys, in this tutorial, we are going to learn about the heap segment and how to use it for storing data in our programs. We will also go into the details of its use in conjunction with the char pointer and struct data types.
There are plenty of legitimate reasons that you might want to record a phone conversation. Let's say you operate a business and take orders over the phone, and you don't want to miss an item. Or perhaps you need to jot down some notes from a recent conference call, and things were just happening too quickly in real time.
What's up readers? Today I'll be introducing to you a new vulnerability called the Format String vulnerability (in case you missed the title). It won't be much, just a little motivation to keep you guys going. A little teaser, if you may.
Welcome to a tutorial explaining functions. This article will help clarify some things we have already been exposed to such as function prototypes, function calls, return values, etc.
Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...
Greetings my fellow aspiring hackers,
Welcome back, my greenhorn hackers! As expected with Null Byte's dramatic growth over the last year, we have added many new aspiring hackers who are still lacking in the basics of networking. In addition, with the new "White Hat" certifications coming out shortly, the exam will require some basic networking skills and knowledge to pass.
Social engineering is a pretty important item in a hacker's toolkit. In Mr robot there was a time, we saw Elliot using social engineering to gain access to his therapist's boyfriend's email and bank accounts by calling him and pretending to be someone from his bank, then Elliot asked him for some info that were really useful to gain access to his account, the target believed to be someone from the bank and gave him the info Elliot was looking for. But How Is It in the Real World?
Windows 10 has so many new features that we couldn't even cover them all with one article. From keyboard shortcuts to revamped search functions and all-new window gestures, Microsoft definitely piled on the fresh functionality in the latest version of their operating system.
Yes, screen savers are fun to look at for a few seconds, but those animations actually used to serve a purpose beyond simple entertainment.
Hello all, this is my first submission to null byte! I noticed something a little strange, particularly that whenever Meterpreter is discussed, it is virtually always in the context of Windows. Granted, the Windows Meterpreter is more powerful than the version that can run on OS X (it has several more commands/options), but I think it is still worth noting how to do it. I've even seen some people mistakenly say that Meterpreter can only be run on Windows, which is not true. Meterpreter can ea...
Mobile payment systems have been around for almost 5 years now, starting with Google Wallet. But when Apple got into the game last year with their new Apple Pay service, things really started to take off. Around this time, Samsung responded by acquiring an up-and-coming mobile payments company that owned the rights to an incredibly innovative technology called Magnetic Secure Transmission (MST).
Welcome back, my hacker novitiates! In an earlier Linux Basics tutorial, I had demonstrated the basics of the Apache web server. Since Apache is the world's most widely used web server on the Internet (as of July 2015, Apache was 38%, IIS was 26%, and Nginx is 15%), the more you know about it and understand it, the more success you are likely to have hacking it.
Welcome back, my novice hackers! Episode 6 of Mr. Robot has come and gone and, as usual, it did not disappoint. Once again, our hero, Elliot, has used his extraordinary intellect and hacking skills to awe and inspire us.
Welcome back, my tenderfoot hackers! In this series, we are exploring the myriad of ways to hack web applications. As you know, web applications are those apps that run the websites of everything from your next door neighbor, to the all-powerful financial institutions that run the world. Each of these applications is vulnerable to attack, but not all in the same way.
Texting has become the king of communication—gone are the days where everyone called each other. These days, it's down-right weird when someone calls first. Whether it be on a phone or on a computer, SMS and MMS messages are the most common way people keep in contact, so why not make sure your app of choice is the best possible one out there?
Welcome back, my rookie hackers! "How can I travel and communicate over the Internet without being tracked or spied on by anyone?" It's a question many Null Byteans have asked me, so I have decided to write a comprehensive article addressing this issue.
NFC, or near-field communications, is a hardware feature that has been built into most Android phones for the last four years. It's essentially a low-power data connection that can be used to initiate a quick command by bringing your device within range of a compatible receiver, be it tap-and-pay with Google Wallet, a file transfer via Android Beam, or a Tasker profile triggered by a specific NFC tag.
This past year was a big one for WonderHowTo. Our biggest yet. In 2014 our writers, curators, and community members helped over 100 million people learn over 270 million new things. That's 40% more people than the total number of students enrolled in every single school from elementary through college across the entire United States. That's pretty awesome. I couldn't be more proud of our entire team, and of course you, the community members who've helped us grow to this point.
If you took a big step back and really looked at the world, you'd see how downright silly our nations look when they put up fences to separate themselves from one another. Creatures big and small roam free while respecting each other's space, but humans create borders and physical barriers to delineate their cultures.
Chrome, Firefox, and Safari all provide built-in features that allow you to save your username and password for your favorite sites, making the process for entering your credentials a breeze when you revisit them.
What if the code you are trying to reverse engineer is obfuscated or somehow corrupted? What if no way is left? Here comes what I like to call (wrongly and ironically) the "brute force of reverse engineering".
As a regular Mac OS X user, I have a love/hate relationship with the "Open With" contextual menu. Sometimes, it has just what I need. Other times, it's often packed with unnecessary or duplicate items, or missing the app I want to open the file up with the most.
Welcome back, my rookie hackers! Now that nearly everyone and everyplace has a computer, you can use those remote computers for some good old "cloak and dagger" spying. No longer is spying something that only the CIA, NSA, KGB, and other intelligence agencies can do—you can learn to spy, too.
As the largest wireless service providers in the United States, AT&T and Verizon Wireless carry some serious clout. Sadly, they use some of this power to heavily modify the Android phones that they offer.
It seems like custom Google Now commands are a dime a dozen these days. With Commandr for Google Now giving non-rooted users their first taste of custom voice commands just a couple weeks ago, you may wonder why we're covering this subject again.
The new LG G3 is the latest Android flagship-level device to be released this year, and it's ready to give the Galaxy S5, HTC One M8, and the OnePlus One a run for their money. Sporting a gorgeous 5.5-inch QHD display, 3GB of RAM, and a huge 300mAH battery, the device looks great and has tons of power to boot.
Welcome back, my aspiring hackers and those who want to catch my aspiring hackers! As most of you know, this series on digital forensics is inspired by the motivation to keep all of you all out of custody. The more you know about the techniques used by law enforcement and forensic investigators, the better you can evade them.
Apple's grand reveal of iOS 8 at WWDC in San Francisco is still a few days away, but that doesn't mean there isn't any speculation as to what features and enhancements might come packed in the new mobile operating system.
Welcome back, my hacker apprentices! To enter the upper echelons of hackerdom, you MUST develop scripting skills. It's all great and well to use other hacker's tools, but to get and maintain the upper hand, you must develop your own unique tools, and you can only do that by developing your scripting skills.
Lenovo brought out the big guns for CES 2014, with the Vibe Z showcased as the Chinese company's' first foray into the LTE smartphone space. Slated for a February release, the ultra-thin and extremely light smartphone will certainly be in the running for top smartphones of this very new year. Photo via CNET
Welcome back, my amateur hackers!
Welcome back, my tenderfoot hackers! I recently began a new series on digital forensics to help tenderfoot hackers from being detected and ultimately, incarcerated. In this installment of that series, we will look at recovering deleted files. This is important to hackers because you need to know that even when you delete files on your computer or on the victim's computer, a forensic investigator can usually recover them.
You know what's awesome? You own a Nexus. That means, with Google's blessing, you have easier access and control over your device than other manufacturers allow. You can really dig in and do some interesting things if you root.
The Nexus 5 is the current Google flagship packed with the latest and greatest of all things Android, but what if you never made the leap from your Nexus 4 smartphone?
It's officially the holiday season, which means everyone will soon be traveling home to spend time with loved ones. And anyone who has any knowledge whatsoever of computers knows what else that means—family members left and right asking you to fix their various technical woes.
If you're reading this, chances are you're a softModder, someone who doesn't let anything stand in his or her way from ultimate customization.
You probably know Lenovo from their low-cost Windows PCs here in the states, but something you may not be aware of is that they also make smartphones. Right now, their biggest market is in China, but a rumored merger with BlackBerry could make Lenovo a contender in North America, not to mention one of the biggest smartphone manufacturers in the world.
