Welcome to an introduction on writing basic malware, an optional sub-series in which I expose you to malware and its technologies. This is written for those who wish to seek a beginning in malware analysis or enlightenment on the subject. We will be justifying the writing and covering types of malware.
Welcome back, my greenhorn hackers! The Holy Grail of any hacker is to develop a zero-day exploit—an exploit that has never been seen by antivirus (AV) and other software developers, as well as intrusion detection system (IDS) developers. In that way, you can exploit systems with your newly discovered vulnerability with impunity!
Welcome back to another tutorial on functions. Last time, we looked inside memory to see what functions looked like in the flesh and all that Assembly was pretty nasty. At least you have some exposure to it. This time, we will be examining how functions work with the stack.
Hello again, reader! In this post, we are going to cover some data types and how to declare variables. It shouldn't be too hard so just sit back, relax, grab some popcorn and enjoy the ride (while you still can!).
Hello there, reader! If you've clicked on this How-to then it means you are interested in learning some C programming or just generally curious about what this page has to offer. And so I welcome you warmly to the first of many C tutorials!
I think it was 1986 when I first discovered my love for making computers say stupid things out loud. My older brother got a Commodore 64 for his birthday, which came bundled with software that would speak out any term you typed in—and boy, that computer sure made a fool of itself after my five-year-old imagination got a hold of the keyboard.
So, you want to become anonymous? well let me give you everything I know (or at least most of it) to you.
It would only make sense that Google is one of the most active app developers on the Android platform, particularly when you consider that they develop the platform itself. From my count, there are an astounding 117 unique apps that the search giant and its subsidiaries have published on the Google Play Store.
If you've been using Windows 10 for a while, you already know that Microsoft incorporated lots of new features into it. So you're probably familiar with Cortana (the new voice assistant), the Edge browser (their replacement for Internet Explorer), the newly resurrected Start menu, and all of the other big changes.
I record close-cropped videos and take macro still shots with my smartphones on a daily basis, so as you would expect, I spend a lot of time cleaning these devices. Over the course of a couple years, I've fine-tuned my cleaning regimen, and at this point, it's down to a near-science.
Every time Windows gets a significant update, the vast majority of existing tweaking utilities become obsolete. For every option that you fine-tuned with one of these tools on Windows 7 or 8, there's a change in the registry or system settings that cause your tweaks to now point to a dead end. This was definitely the case with Windows 10, since there were so many sweeping changes that very few existing options carried over.
When I get struck by a craving for something SCJ (savory, crunchy, juicy), nothing fits the bill better than a BLT. But why settle for the sandwich form when there are so many other possibilities? Some of my favorite alternative ways to serve up a BLT are 1) as a salad, 2) in tomato cups, 3) in mini bread bowls, 4) as lettuce wraps, 5) as a dip, and 6) in bacon cups.
As Android's de facto virtual assistant, Google Now lets us speak directly to our phones in plain English to answer our questions and perform many basic tasks. With the app open, just say "Okay Google," then wait for the beep, and ask almost any question.
You can beef up the security on your Mac all you want, but all the firewalls and antivirus apps in the world mean nothing when that can of soda tips over on your Macbook, destroying your laptop and all its data forever.
There's a whole world of wallpapers out there. Apple always includes a selection of stock wallpapers, some unique to every iPhone model you have. Of course, sometimes, stock wallpapers don't cut it. Sometimes, you want to add your own style to your home screen and lock screen. In these cases, using an app to find the best wallpapers out there can be just what you need.
Researchers at the cyber security firm Zimperium have recently uncovered a vulnerability in roughly 95% of Android devices that has the potential to allow hackers to take total control over your phone with a simple picture message (MMS). The gritty details of this exploit have not been made public yet, but hackers now know the general framework for this type of attack, so you can be certain that they'll hammer out the details in no time.
Don't like how Apple's default Radar ringtone — or any other tone — wakes you up in the morning? Then don't use them as your alarm sound. Instead, use your favorite song to get you out of bed. Whether you enjoy an acoustic tune or a heavy, energetic jam, you can choose any Apple Music song you want, or any track in your personal Music library, to get you going each day.
So, we all probably know that when you run a trojan made by Metasploit, nothing will appear to happen. This is a sign for me to immediately check my Task Manager, but for an unsuspecting victim, it will just seem like a broken file. It is likely that they will delete this "broken file" once they see that it "doesn't work." In order to prevent this, we need to disguise the trojan.
The right music can spur you to pick up the pace during an intense workout, pep you up before you hit the treadmill or walking path, and even encourage you to lift for just a few extra reps. Although we all have our favorite workout playlists, scientists have discovered what it is, exactly, that makes you workout harder when certain songs begin.
We recently lost Grooveshark, the free music streaming service that supplied users with a huge catalog of free music anytime, anywhere. Since its shutdown, I have been scrambling to find a half-decent alternative, and my expectations were more than exceeded when I found NetEase Music.
Notes on iOS has never been a particularly great app due to a lack of overall features compared to other note-taking apps like Evernote or Microsoft OneNote.
Hi everyone! In the previous part of this series we introduced remote code arbitrary execution via buffer overflows using all of our past experiences.
One of the latest home-improvement gadgets out there today, smart lighting, has become more popular as prices come down. That being said, its still quite a penny to shell out. In this article, I'll go through a few of the top products out there today, including the Philips Hue, Belkin WeMo, and Lifx.
Technology has progressed by leaps and bounds and has blessed people in a number of ways, but at the same time, it has troubled them also. Computers are now used in every aspect of life. No matter if you are a businessman, an employee, a student, or even a housewife, a computer can assist you in your routine work. You save your personal information, documents, and other similar sensitive stuff on your computer that can hurt you if they get compromised.
Facebook essentially strong-armed us all into installing their standalone Messenger app for mobile devices, but the recent initiative that allows third-party development on the platform definitely makes it worth your time.
Kitchen tools are a personal thing. One hard lesson for me to learn is that just because something is popular doesn't mean that it's right for me. Take the slow cooker, for instance. Many rave about it, but I never cottoned to the thing. However, the more research I do, the more I think the pressure cooker might be a game changer for my cooking style.
There's nothing more jarring than the sound of your morning alarm. Even hearing it on others' phones, hours after your own abrupt wakeup, can cause you to flinch in fear. Though we depend on that shrill sound to get up each morning, it's actually better to wake up naturally—so don't even think about hitting that snooze button.
Welcome back, my hacker novitiates! Eluding and evading antivirus software and intrusion detection systems is one of the most critical tasks of the hacker. As soon as a new exploit is developed and discovered, the AV and IDS developers build a signature for the attack, which is then likely to be detected and prevented.
I'll admit it: I've spent many eight-hour workdays stuck at my desk, staring at my computer as my breaks slip past unnoticed. I frequently tell myself I'll take one in a few more minutes—but somehow, the entire day will pass and I won't have taken a single break.
Welcome back, my novice hackers! In my series on cracking passwords, I began by showing off some basic password-cracking principles; developed an efficient password-cracking strategy; demonstrated how to use Hashcat, one of the most powerful password-cracking programs; and showed how to create a custom wordlist using Crunch. In this tutorial, I will show you how to create a custom wordlist based upon the industry or business of the targets using CeWL.
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.
Welcome back, my nascent hackers! We have spent a lot of time in previous tutorials focused on hacking the ubiquitous Windows systems, but the vast majority of "heavy iron" around the world are Linux or Unix systems. Linux and Unix dominate the world of Internet web servers with over 60% of the market. In addition, Linux and Unix servers are the operating system of choice for major international corporations (including almost all the major banks) throughout the world.
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.
Welcome back, my budding hackers!
Arcades have long faded away from popularity, but their legacy is being kept alive thanks to emulators and the avid fans who grew up loading quarters into all of those coin-op games. Although nothing beats an actual arcade environment, my favorite emulator from the early 2000s has found a new home on Android, and with it a second life.
What if someone asks you to do a Nmap scan but you left your pc at home? What if a golden opportunity shows during a pentest but you were walking around the building, taking a break?
Because of Android's massive array of supported smartphones that carry vastly different display sizes and resolutions, the operating system uses a value known as DPI to determine the size of icons and visual assets that will best suit a given screen.
In the Apple's iOS beta 3, we were introduced to a new iCloud Drive feature, an option to disable QuickType, time indicators for Recently Deleted pics, and a way to keep "self-destructing" media.
Welcome back, my tenderfoot hackers! In continuing my series on digital forensics using Kali, I want to introduce you to two complementary tools, both built right into Kali Linux. These are Brian Carrier's tools Autopsy and Sleuth Kit.
If you're like me, you spend a lot of time on your computer, which can be damaging to your eyes in the long run. Studies have shown that staring at a computer screen or television up close for extended periods of time can have harmful effects on your vision.
