A Look into Internet Marketing including common pitfalls to avoid and how to build a userbase. Part 1 of 2 - How to Get into Internet Marketing.
In general, hacking and information security is not just one discipline, but a number of them, and today we will look into some of the networking concepts.
A virtual private network is a necessary part of your arsenal if you're insistent on surfing the web privately and securely on your iPhone. The App Store is littered with hundreds of different VPN services that encrypt traffic and mask your IP address, but what they all have in common are connectivity issues.
It's been said time and time again: reconnaissance is perhaps the most critical phase of an attack. It's especially important when preparing an attack against a database since one wrong move can destroy every last bit of data, which usually isn't the desired outcome. Metasploit contains a variety of modules that can be used to enumerate MySQL databases, making it easy to gather valuable information.
Let's be honest, nobody enjoys doing cardio — they tolerate it. That dreadful, loathsome feeling you experience when you're doing cardio workouts isn't unique to you, it's almost universal. Sure, it gets easier the more you do it, but there are some ways to make it better now.
Hashes are commonly used to store sensitive information like credentials to avoid storing them in plaintext. With tools like Hashcat, it's possible to crack these hashes, but only if we know the algorithm used to generate the hash. Using a tool called hash-identifier, we can easily fingerprint any hashes to discover the right Hashcat mode to use to retrieve a password.
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.
You may not have thought of dorks as powerful, but with the right dorks, you can hack devices just by Googling the password to log in. Because Google is fantastic at indexing everything connected to the internet, it's possible to find files that are exposed accidentally and contain critical information for anyone to see.
Google is an incredibly useful database of indexed websites, but querying Google doesn't search for what you type literally. The algorithms behind Google's searches can lead to a lot of irrelevant results. Still, with the right operators, we can be more exact while searching for information that's time-sensitive or difficult to find.
One of the most common web application vulnerabilities is LFI, which allows unauthorized access to sensitive files on the server. Such a common weakness is often safeguarded against, and low-hanging fruit can be defended quite easily. But there are always creative ways to get around these defenses, and we'll be looking at two methods to beat the system and successfully pull off LFI.
When researching a person using open source intelligence, the goal is to find clues that tie information about a target into a bigger picture. Screen names are perfect for this because they are unique and link data together, as people often reuse them in accounts across the internet. With Sherlock, we can instantly hunt down social media accounts created with a unique screen name on many online platforms simultaneously.
Smartphones have put an end to camcorders. If you want to capture memorable moments in high quality, look no further than that technological marvel in your pocket. Recent Galaxy phones are shining examples of how far we've come — but the more capable a camera gets, the more complicated things can be.
The year in augmented reality 2019 started with the kind of doom and gloom that usually signals the end of something. Driven in large part by the story we broke in January about the fall of Meta, along with similar flameouts by ODG and Blippar, the virtual shrapnel of AR ventures that took a wrong turn has already marred the landscape of 2019.
The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.
It's common for IoT devices like Wi-Fi security cameras to host a website for controlling or configuring the camera that uses HTTP instead of the more secure HTTPS. This means anyone with the network password can see traffic to and from the camera, allowing a hacker to intercept security camera footage if anyone is watching the camera's HTTP viewing page.
Many online users worry about their accounts being breached by some master hacker, but the more likely scenario is falling victim to a bot written to use leaked passwords in data breaches from companies like LinkedIn, MySpace, and Tumblr. For instance, a tool called H8mail can search through over 1 billion leaked credentials to discover passwords that might still be in use today.
Cross-site scripting can be one of the easiest vulnerabilities to discover, but to be successful with this type of attack, it is essential to learn how to get past filters. In the previous guide, we explored some ways to do this, such as abusing attributes and event handlers and tricking the application into accepting unusual characters. Now, let's take a look at more techniques used to defeat filters.
Cross-site scripting is one of the most common vulnerabilities found on the web today, with repercussions of this type of flaw ranging from harmless defacement to sensitive data exposure. Probing for XSS can be tedious and time-consuming for an attacker, but luckily there are tools available to make things a little easier, including Burp Suite, Wfuzz, and XSStrike.
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.
Due to weaknesses in the way Wi-Fi works, it's extremely easy to disrupt most Wi-Fi networks using tools that forge deauthentication packets. The ease with which these common tools can jam networks is only matched by how simple they are to detect for anyone listening for them. We'll use Wireshark to discover a Wi-Fi attack in progress and determine which tool the attacker is using.
Hacking Wi-Fi is a lot easier than most people think, but the ways of doing so are clustered around a few common techniques most hackers use. With a few simple actions, the average user can go a long way toward defending against the five most common methods of Wi-Fi hacking, which include password cracking, social engineering, WPS attacks, remote access, and rogue access points.
Database technology has vastly improved the way we handle vast amounts of data, and almost every modern application utilizes it in one way or another. But the widespread use of databases naturally invites a slew of vulnerabilities and attacks to occur. SQL injection has been around for awhile, and as such, there are many defense methods in place to safeguard against these types of attacks.
There has been significant debate over law enforcement's right to access our digital devices in recent years. New tools from Grayshift and Cellebrite are popping up faster than ever to help government agencies, as well as traditional hackers, break into iPhones. If you're concerned, you can take steps right now to beef up your passcode and prevent outsiders from gaining access to your device.
With ultra competitive games like Fortnite Battle Royale and PUBG taking the mobile world by storm, gamers are looking for ways to get a leg up on the competition. One of the biggest advantages you can give yourself is the ability to aim and shoot while on the move, but that's not exactly easy with a touchscreen.
As the third-largest smartphone manufacturer in the world, Apple devices are a constant target for hackers everywhere. While iOS has seen fewer common vulnerabilities and exploits (CVEs) in recent years, iPhones still aren't hack-proof. Fortunately, you can strengthen your security with the help of a few apps.
You may have seen news reports over the last two days detailing a major security flaw in virtually all smartphones. The devices that are at risk are not limited to either iPhone or Android — all of us are affected. If you want to make sure your smartphone and its data stay secure, there are a few steps you can take.
Just in time for the holiday season, Lenovo has released its Mirage AR head-mounted display with the Star Wars: Jedi Challenges game and accessories. Unfortunately, while its price point is a fraction of most other AR headsets, at the moment, it does have a few issues with the setup process.
When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.
Google just bought a huge chunk of HTC for $1.1 billion. They're bringing in around 2,000 employees, mostly from the hardware division, and these folks will presumably work under hardware chief Rick Osterloh. There's a massive patent portfolio involved, too, so stop me if you've heard this before — Motorola, anyone?
On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
If you have a taste for sweets, you have at least one thing in common with mosquitoes. While too much sugar is unhealthy for humans, a new product makes sweets deadly to mosquitoes.
Whether your palate runs to domestic or imported, a piece of cheese can be a real treat for the senses. Its smell, taste, and texture are all parts of its appeal. A big part of what makes that savory wonderfulness comes from the microbes in and on the cheese. Thanks to a team of researchers dedicated to studying those microbes, we have a better understanding of their importance to cheese and us.
RouterSploit is a powerful exploit framework similar to Metasploit, working to quickly identify and exploit common vulnerabilities in routers. And guess what. It can be run on most Android devices.
