In the first guide, we laid the groundwork for our ultimate goal of uploading and running the unix-privesc-check script on our target. We identified an input field vulnerable to SQL injection and utilized Sqlmap to set up a file stager on the server. Now, we're ready to upload files and execute the script, so we can identify any misconfigurations that could lead to privilege escalation.
When joining a new network, computers use the Address Resolution Protocol to discover the MAC address of other devices on the same network. A hacker can take advantage of ARP messages to silently discover the MAC and IP address of network devices or actively scan the network with spoofed ARP requests.
You may not know it, but the IPv4 address of your computer contains tons of useful information about whatever Wi-Fi network you're on. By knowing what your IPv4 address and subnet mask are telling you, you can easily scan the whole network range, locate the router, and discover other devices on the same network.
Planning a vacation overseas can sometimes feel overwhelming with the number of things you need to remember before heading out. Since smartphones keep us connected at all times, it's essential that you have everything you need here as well. Unexpected events can arise while on your trip, and you should be prepared for anything like a survival expert.
Business hours and addresses change, but they're not always updated on Yelp by business owners for the rest of us to see. Showing up when a business is closed or going to the incorrect address is a major annoyance, which is why the company allows us, the customers, to help update business information through the Yelp mobile app on iOS and Android. If owners won't do it, somebody has to.
With a simple social engineering trick, sudo passwords can be captured in seconds without the target's knowledge. The passwords can then be saved to a file or exfiltrated to another computer on the network.
One of the best things about Android is the ability to customize every aspect of your device to make it your own. However, unless you have prior knowledge or experience with every single setting available to you, you might have missed a few critical features without even knowing it. Some settings are easy to find, while others might be tucked away in another menu of their own.
Switching phones has never been easier. Google backs up most of your app data on the cloud, which can then be restored onto your new phone. Sadly, Signal doesn't use this feature since it could compromise your security. Instead, Signal stores encrypted backups locally, requiring a bit of work to restore these messages.
Picture this: You finally get that awesome angle, the perfect selfie. You can't wait to post it on your Instagram, except there's one problem — it looks a little flat and the colors just seem off. Maybe it's the lights? Or maybe your new smartphone camera isn't as good as you thought? How are your friends getting those beautiful photos they've been posting on social media?
A relay is an electrical component that works like a light switch, where it's turned on or off with an electrical signal. By connecting a relay to a Wi-Fi connected microcontroller like an ESP8266, you can build a connected switch that can be controlled from the web browser of any device connected to the same Wi-Fi network — all for just a couple of dollars.
Almost every phone comes with biometric security of some sort these days, but the same can't be said of Windows computers. While fingerprint scanners are becoming increasingly common with laptops and desktops, they're nowhere near ubiquitous. Thankfully, your phone's scanner can be used as a sort-of remote authentication point for your PC.
MoviePass was once the best subscription service on the market for getting cheap movie tickets. For the price and the number of films you could see and save money on, it was unbeatable, but recent changes to the service have made it less enticing. While it still works well for some users, others may have to rely on other options. Personally, I'm leaning toward the latter.
Creating doodles on an iPhone is made easy thanks to the "Draw" tool in Notes and "Digital Touch" for iMessages, but these are limited in scope. Drawing in Notes has no animated effects, and while Digital Touch does, its drawing tools are lacking and the animations can only live within iMessages. If it's animations you want, Apple has another app that can help you create them.
The ability to execute system commands via a vulnerable web application makes command injection a fruitful attack vector for any hacker. But while this type of vulnerability is highly prized, it can often take quite a bit of time to probe through an entire application to find these flaws. Luckily, there is a useful tool called Commix that can automate this process for us.
All of the new iPhones from 2018 were released with dual-SIM support, but none of them were capable of actually using the eSIM in iOS 12, only the physical nano-SIM. But on iOS 12.1 and later, you can finally take advantage of eSIM so you can have, say, a business and personal plan on your iPhone XS, XS Max, or XR at the same time.
So, you rooted your Pixel 2 or 2 XL and everything seems to be working quite well. However, a month passes, and you get a notification to install the monthly security update. Like clockwork, Google has been pushing out OTA security patches every single month for a while, but there is a new problem for you at this point — as a rooted user, you are unable to apply the update correctly.
If you've ever been on the receiving end of a threatening phone call, you'll immediately know the value in being able to record phone conversations on your iPhone. Beyond that extreme example, however, recording calls is still an extremely useful feature to have for important conversations like business meetings and verbal agreements, and it's totally doable with a third-party app.
The new iPhone XS and XS Max have more issues than just their hefty price tags. Customers have only had the phones for a handful of days, but some are already complaining of cellular and Wi-Fi connectivity issues on both models. If your experience is the same on your XS or XS Max, there are steps you can take to get your iPhone reliably back online.
All phones (yes, iPhones too) slow down over time. As your device gets bogged down by various apps and you begin to run out of storage, it's just an inevitability. That doesn't make it any less frustrating ... I mean, is there anything more annoying than a slow phone? My answer: No. Of course not. It's the single most annoying thing ever.
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.
In most macOS hacks, a non-root terminal is used to create a backdoor into the device. A lot of damage can be done as a low-privileged user, but it has its limitations. Think twice before granting a file permission to execute — an attacker might be able to convert your harmless scripts into persistent root backdoors.
Since early March, iOS users have been able to enjoy the most popular video game sweeping the rounds. Android users have been left envious as they wait for a "few months," the only vague release date given by Epic Games. In the meantime, there are a few ways we can still satisfy our urge to play.
Just like cash, bitcoin is used for everything from regular day-to-day business to criminal activities. However, unlike physical cash, the blockchain is permanent and immutable, which means anyone from a teen to the US government can follow every single transaction you make without you even knowing about it. However, there are ways to add layers of anonymity to your bitcoin transactions.
One of the most critical bugs to come out in the last five years was Shellshock, a vulnerability which allows attackers to execute arbitrary code via the Unix Bash shell remotely. This vulnerability has been around for a while now, but due to the ubiquity of Unix machines connected to the web, Shellshock is still a very real threat, especially for unpatched systems.
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.
As the official release of iOS 12 nears closer each day, Apple continues to update its betas. The company released the fourth beta of the upcoming software to developers Tuesday, July 17, exactly two weeks after the release of the third developer beta which came out just a few days before the second public beta.
Command injection is a technique used by hackers to execute system commands on a server, usually via a web application or some kind of GUI. This can happen when an application provides some sort of functionality to the user involving the use of system commands. When the input is not properly sanitized, commands not originally intended to be run are allowed to be executed.
Wi-Fi tools keep getting more and more accessible to beginners, and the LAZY script is a framework of serious penetration tools that can be explored easily from within it. This powerful and simple tool can be used for everything from installing new add-ons to grabbing a WPA handshake in a matter of seconds. Plus, it's easy to install, set up, and utilize.
After installing Ubuntu as your primary OS, you should have protected against USB Rubber Ducky payloads, defended against hard drive forensics, and reduced the overall attack surface against physical strikes. When defending against network-based attacks, you'll want to minimize hardware disclosures, prevent packet sniffers, harden firewall rules, and much more.
The latest Star Wars movie, Solo: A Star Wars Story, has grossed almost $350 million worldwide during its first month in theaters. This is a good opportunity to discuss how hackers can use media hype (in this case, Hollywood movie hype) to disarm an unsuspecting Windows user into inserting an evil USB stick into their computer.
Apple's own Photos app received some pretty amazing updates in iOS 11, but does iOS 12 have what it takes to one-up last year's Photos improvements? We think so.
When you can't reach your iPhone or don't have it on you, how do you get help from emergency services? Unless you have one of those life-alert mobile triggers, someone nearby, or some amazing telepathy skills, hope might be the only answer — unless you wear an Apple Watch, that is.
Passwords and data stored in web browsers are extremely valuable to hackers. If not for financial gain, black hat hackers may still leak your passwords and personal information for amusement. Never undervalue what you're worth to a hacker.
After setting up your phone, there are a number of things you should do immediately before download your favorite apps. Specifically, now that your data is on the device, you need to take steps now to ensure it's both protected and retained. Fortunately, most of these steps are a one-time process.
After finding and monitoring nearby wireless access points and devices connected to them, hackers can use this information to bypass some types of security, like the kind used for Wi-Fi hotspots in coffee shops, hotels, and in flights high above the ground. By swapping their MAC address for that of someone already connected, a hacker can bypass the MAC filter and connect freely.
Recently, many manufacturers have started offering phones with a clean, stock Android UI. Motorola, Essential, Nokia, and OnePlus are probably the biggest names that have listened to user feedback and shifted more towards AOSP. But if your phone still has a bloated OEM skin, there are a few things you can do about it.
Nova Launcher is more than just a home screen replacement. It is a tool which can reshape how users interact with their Android devices. Thanks to a regularly growing feature list, Nova has evolved into more than just a launcher. Now, Nova is an effective way to increase your productivity.
Nmap is possibly the most widely used security scanner of its kind, in part because of its appearances in films such as The Matrix Reloaded and Live Free or Die Hard. Still, most of Nmap's best features are under-appreciated by hackers and pentesters, one of which will improve one's abilities to quickly identify exploits and vulnerabilities when scanning servers.
One of Android's most glaring weaknesses is its lack of an iMessage equivalent. That is, of course, until now. There's one app that will allow Android users to experience iMessage on their non-Apple phone, complete with end-to-end encryption, message effects, and group messaging.
Many people think antivirus apps are useless — why pay a subscription fee when most malware can be avoided with common sense? But the thing is, there were an estimated 3.5 million malicious Android apps discovered last year, with many of them making their way onto the Play Store. As this number continues to rise, can you truly depend on common sense to protect you?
