Hello fellow gray hat hackers, I wrote a program in python that helps me to fill up my proxychains.conf file, so I don't have to manually enter in the proxies. I figured I will give a little how-to of how I did it and maybe I could help some of you(hackers) out there to stay anonymous.
If you purchased something from iTunes, the iOS App Store, iBooks Store, Apple TV App Store, or the Mac App Store and it doesn't work, didn't download, is buggy, or wasn't what you thought it was, you can get a full refund from Apple—you just have to know how to ask.
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.
My father never cooked a meat without some kind of marinade. He always used a slew of ingredients: salt, pepper, Season-All, Cajun seasoning, vinegar, olive oil, liquid smoke, Worcestershire, hot sauce, onions, lemons... I'm pretty sure this isn't a complete list, but I've honestly forgotten the rest! It always tasted amazing, but the long list of ingredients was definitely a detriment whenever replicating the marinade.
Well, first things firsts, it's been awhile! I'm sorry the series has been dead for a little bit, but I recently hit some personal relationship issues and needed to take some time to think. But, now that it's all said and done, the dust can settle and we can start training again!
Mostly all hackers like to have a laugh. We like to have fun! We like to troll. And maybe, even cause some havoc once in a while. But, while we do this, we must always stay in the line of the law.
The menu bar is a great place to perform quick searches, track battery life, and switch Wi-Fi networks on your Mac, but it can do way more than that if you let it. I've rounded up some menu apps below that not only have features that will boost your productivity, but are lightweight enough to run entirely from the menu bar.
Hi everyone! In the previous part of this series we introduced remote code arbitrary execution via buffer overflows using all of our past experiences.
Journals are a great source of hilarity and embarrassment, detailing everything from your elementary school crushes to those super awkward middle school dances. While rereading your old hand-scrawled entries might make you cringe, that old journaling habit could benefit you as an adult.
What is Programming? Why need to learn? How to get started? Which language to choose? While surfing web, you must be encountering various softwares, games, etc. and might be thinking to make one, but don't know where to start. Here, I am starting series in Programming.
Welcome back, my aspiring hackers! One of those areas of Linux that Windows users invariably struggle with is the concept of "mounting" devices and drives. In the Windows world, drives and devices are automatically "mounted" without any user effort or knowledge. Well, maybe a bit of knowledge. Most Windows users know to unmount their flash drive before removing it, but they usually think of it as "ejecting" 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 back, my aspiring hackers!
Welcome back, my fledgling hackers! Nearly every commercial enterprise worth hacking has an intrusion detection system (IDS). These network intrusion detection systems are designed to detect any malicious activity on the network. That means you!
Automating tasks on your Samsung Galaxy Note 2 is nothing new. Everything from adjusting screen brightness, to turning on the flashlight, to saving Snapchat pictures can be done automatically with the help of a few function-specific apps. The only problem with task-specific apps is that you have to download a handful of them to get everything you want, which can quickly add up. Now, thanks to AutomateIt, you can clean up your app drawer on your Note 2 and create loads of custom tasks using ju...
When filtered through the prism of the top stories of the year, the business of augmented reality 2019 was defined as much by epic failures of AR startups as it was by the promising developments that propelled the industry forward into 2020.
When I first found out about Nreal, back in the spring of 2018, the most interesting thing about the company's story was the founder's background. Chi Xu, the CEO and founder of Nreal, previously worked at Magic Leap as a software engineer.
On Wednesday, the tech world woke up to fairly shocking news with the announcement that AT&T would be the exclusive wireless carrier for the forthcoming Magic Leap One, as well as an investor in Magic Leap.
Every industry has its own jargon, acronyms, initializations, and terminology that serve as shorthand to make communication more efficient among veteran members of that particular space. But while handy for insiders, those same terms can often create a learning curve for novices entering a particular field. The same holds true for the augmented reality (also known as "AR") business.
Some of us woke up at the KRACK of dawn to begin reading about the latest serious vulnerability that impacts the vast majority of users on Wi-Fi. If you weren't one of those early readers, I'm talking about the Key Reinstallation Attack, which affects nearly all Wi-Fi devices.
Regarding foodborne pathogens, eating fish is not as hazardous as it was a few years ago — but if fins are on the menu, it's good to have a heads-up about what's good and what's bad these days.
Killing more than 29,000 people each year, infection with Clostridium difficile (C. diff or CDI) is the most common healthcare-associated infection in the US. In a disturbing development, new research reveals recurring cases of the infection are soaring.
There is an Indian story called the Legend of Paal Paysam, and while it doesn't seem like it at first, it has a lot to say about what motivated Paul Travers in the augmented reality space.
Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers. A couple weeks ago, it's possible that a man and his six-month old child spread the measles in several Seattle-based locations. Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?
When Kaci Hickox, a Doctors Without Borders nurse, returned to New Jersey from working with Ebola patients in West Africa in 2014, she was surprised by her reception. Instead of a quiet return to her home in Maine after four weeks on the front line of Ebola treatment, she was quarantined by the State of New Jersey in Newark. She later filed a lawsuit in U.S. District Court for violation of her civil rights, false imprisonment, and invasion of privacy.
Welcome back, everyone. In the previous part of this rapid-fire miniseries, we built the victim portion of the shell. Today, we'll be building the attacker portion. This script will initialize interaction with the victim portion of the shell, send commands, and receive the output.
Home cooks are often quite intimidated when trying to reproduce the delicious ethnic dishes they enjoy at various restaurants. Thankfully, there are definite flavor profiles and spice/seasoning/herb combos that are very specific to various regional cuisines and cultures; with a little guidance, you can create dishes that are tasty homages to the cuisines you love to eat. In this two-part article (second part here), I'll cover both categories and sub-categories of some of the most popular ethn...
Welcome back, my greenhorn hackers!
In recent weeks, some people have been shunned from the Null Byte community because they expressed "black hat" aspirations. This is because Null Byte is the "white hat" hacker training/playground. Although most of us think we know what that means, it does beg the question; "Who and what is a white hat hacker?"
So this is my methodology for this project of writing a rootkit. Please leave feedback on what is right/wrong. I tried to simplify concepts the best I could however...
Developing GUI apps in python is really cool. I ask those who understand the language to help convert some of the command-line or console programs or apps ( I mean programs that are useful to a hacker ) to GUI. I know GUI makes us lazy and not wanna learn but we should all know its fast. Today's tutorial is on p2p chat app I developed last week and decided to share it with the community since its kinda cool.
NOTICE: Ciuffy will be answering questions related to my articles on my behalf as I am very busy. Hope You Have Fun !!!
What separates the work habits of the ultra-productive from us mere mortals struggling to check items off our never ending to-do lists? While the answer to that question is by no means simple, one undeniable factor in their success is a clearly defined, highly organized workflow.
Welcome back, my neophyte hackers! Many newbie hackers seem to be confused regarding the process or methodology to employ a successful hack. Most want to simply go straight to the exploit without doing the due diligence to make certain that the hack will work and you won't get caught.
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 neophyte hackers! There are innumerable ways to hack a system. We must not overlook any of the possibilities if we want to "own" the system. As systems become more and more secure, we need to be vigilant in our search for weaknesses. In this hack, we'll look at abusing the trust that a user innately has for software updates to install our own listener/rootkit on their system.
UPDATE (February 26, 2014) Yesterday, the U.S. House of Representatives passed H.R. 1123 with a 295-114 vote decision. The ruling repeals the 2012 Library of Congress (LOC) decision that limited the ability to legally "unlock" your smartphone (see below).
Windows 10 passwords stored as NTLM hashes can be dumped and exfiltrated to an attacker's system in seconds. The hashes can be very easily brute-forced and cracked to reveal the passwords in plaintext using a combination of tools, including Mimikatz, ProcDump, John the Ripper, and Hashcat.
My autistic son loves music. One afternoon, when he was nine, I downloaded GarageBand to his iPhone to help with the boredom of a long wait at a doctor's office. Instead of pacing or escalating into a meltdown, he spent the entire hour and a half practicing, learning, and composing. When we finally left that day, the rest of us exhausted and irritated, he shared his first composition with a big smile.
