Snatching the login credentials of a locked computer just got easier and faster, thanks to a technique that requires only $50 worth of hardware and takes less than 30 seconds to carry out.
Rob Fuller, a principal security engineer at R5 Industries, said the hack works reliably on Windows devices and has also succeeded on OS X, although he's working with others to determine if it's just his setup that's vulnerable. The hack works by plugging a flash-sized minicomputer into an unattended computer that's logged in but currently locked. In about 20 seconds, the USB device will obtain the user name and password hash used to log in to the computer. Fuller, who is better known by his hacker handle mubix, said the technique works using both the Hak5 Turtle ($50) and USB Armory ($155), both of which are USB-mounted computers that run Linux.
- Use the Visual Studio debugger to quickly find and fix bugs across languages. The Visual Studio for Mac debugger lets you step inside your code by setting Breakpoints, Step Over statements, Step Into and Out of functions, and inspect the current state of the code stack through powerful visualizations.
- The war between Mac and Windows devotees has been raging for decades, and last week we asked you to weigh in. Today we're taking a look at the best arguments on both sides to offer a clear picture.

Mac OS X Lion One of Apple’s slickest moves was to integrate the Mac App Store into Lion. Based on the overwhelming success of the iPhone app store, the Mac App Store is built into the Dock for. Aug 11, 2015 Mac vs PC: Viruses – a 2006 Apple ad satirising Windows’ vulnerability to viruses at the time. The perception that Macs are safer to use than PCs persists in some quarters to this day. Apr 25, 2020 Used to be a disadvantage for Mac, but now is a tie. In this article, I have only touched some of the factors when considering a Mac vs a PC. There are many other areas I could expand into, such as software availability, specific ergonomic and design concerns and much more.
'First off, this is dead simple and shouldn’t work, but it does,' mubix wrote in a blog post published Tuesday. 'Also, there is no possible way that I’m the first one that has identified this, but here it is (trust me, I tested it so many ways to confirm it because I couldn’t believe it was true).'
The pilfered authentication hash can either be cracked or downgraded to another hash that can be used to gain unauthorized access. In the event the machine is running an older version of Windows, the returned NTLMv1 hash can be converted to NTLM format no matter how complex the underlying plaintext password is. And from there, it can be used in pass-the-hash-style attacks. A NTLMv2 hash used by newer versions of Windows would require more work. In mubix's tests, hashes returned by even a fully up-to-date El Capitan Mac were able to be downgraded to a susceptible NTLMv1 hash.
The Hak5 Turtle and USB Armory are both full Linux computers that are capable of emulating a USB Ethernet device. Mubix outfitted them with simple configuration modifications that present the hardware as a DHCP server. The status makes the USB device the default gateway that's able to receive network traffic. Using a hacking app known as Responder, the device can then receive authentication tokens. Mubix reports that some people have gotten a similar setup to work on a RaspberriPi Zero, making the cost of this hack $5 and about 10 minutes of configuration setup.
Here's a video of it in action:

What is happening in the video, is the USB Armory is being plugged into a locked (but logged in) system. It boots up via the USB power, and starts up a DHCP server, and Responder. While it's doing this, the victim is recognizing it as a Ethernet adapter. The victim then makes route decisions and starts sending the traffic it was already creating to the Armory instead of the 'real' network connection. Responder does its job and responds to all kinds of services asking for authentication, and since most OSs treat their local network as 'trusted' it sees the authentication request and automatically authenticates. Seeing that the database of Responder has been modified the Armory shuts down (LED goes solid).
The demo underscores the age-old maxim equating physical access with owning or 'pwning' a device. https://luckyportland.netlify.app/ddj-sx-software-for-mac.html. Still, the lock screen is a regular feature in most offices for users who don't want to turn off or physically bring their computer with them while using the restroom. And for that reason, a hack that surreptitiously steals the passwords of such computers in 20 seconds is noteworthy.
Mubix said he's working on a follow-up post suggesting ways to prevent the attack. In the meantime, he's referring people to this mitigation technique, which he says works 'pretty well.'
Can’t decide if you should buy a Mac or PC? It’s a tough decision because both platforms have different advantages and disadvantages. It really also depends a lot on external factors like what other devices you own and what kind of software you use.
Dot hack infection mac anu. For example, if you own an Xbox One, a Windows Phone, a Surface tablet and all the other computers in your home are Windows PCs, then it might be more convenient to stick with a PC. On the other hand, if you own an iPhone, an iPad, an Apple TV, and an AirPrint enabled printer, then a Mac would fit in really well with those other devices.
Additionally, even if you end up with a mixed environment with Windows and Mac devices, it’s pretty easy to share data across devices. It’s also fairly easy to access Mac files from a Windows PC and vice versa. You can even connect a Mac-formatted drive to a Windows PC and view the files directly. If you’re new to Mac, you’ll be happy to know that OS X has an equivalent for pretty much every feature in Windows.
So, without further ado, let’s go into the pros and cons for each platform, which includes the hardware and software. Hack parental controls mac. Obviously, this is a very biased and opinionated article, so feel free to share your thoughts if they are different.
Mac Pros and Windows Cons
- Macs have a built-in program called BootCamp, which allows you to install Windows, Linux or other operating systems in addition to OS X. Setting up a dual boot system in OS X is infinitely easier than it is in Windows. It’s also super easy to switch between the two operating systems.
- Macs work better with other Apple products in terms of software. This includes features like Handoff, iMessage, iCloud, iCloud Drive, iCloud Photo Library, iCloud Keychain, Find My iPhone, etc. Microsoft has tried to copy this, but only partially.
- Macs are less complicated and more intuitive to use. This is a very debatable point and the reason why I also list it as a con in the section below. If you’ve always been a Windows user, it can initially be counter-intuitive to use, however, I’ve found that it’s more logical once you get used to it.
- Even though Macs can get viruses or malware, the number of threats is still significantly less than for Windows just because the Windows base is so much larger.
- Almost all new PCs come installed with loads of bloatware from PC manufacturers, which requires manual removal. Mac computers have pre-installed software, but only from Apple and they don’t slow down your system. If you’re technically savvy, this is a non-issue, otherwise it can be a major nuisance.
- Apple has excellent customer support, AppleCare warranty programs, and exclusive Apple Stores where you can take your Mac or other Apple products for repairs, training or other issues.
- Macs are sleek and visually appealing. To get something close from PC manufacturers usually ends up negating the higher cost factor for Apple products.
- Speaking of cost, Macs are more expensive than PCs, but they also hold their resale value far better than PCs.
- Apple computers have some of the highest customer satisfaction rates in the industry. When you purchase a Mac, you are getting a high-quality machine. This can be true for PCs also, but with so many manufacturers and configurations, getting the best quality can be more difficult.
- Macs tend to be a bit more innovative in design and features. For example, Macs include Thunderbolt, USB Type C ports, multi-touch trackpads, force touch, keyboard backlighting and more.
- Macs can read NTFS or FAT formatted hard drives. Windows cannot read Mac formatted drives unless you install a third-party program.
- The iMac, the only Mac desktop other than the Mac Pro, is an all-in-one computer that you can get with a 4K or 5K display, something that really doesn’t exist in the Windows market at all unless you get an ultra-expensive custom rig. There is the HP Envy, but it isn’t as good as the iMac.
PC Pros and Mac Cons
Easier To Hack Pc Vs Mac Os
- PCs are manufactured by many different companies, resulting in a huge selection of devices with a wide variation in prices. With Apple, you have only a few choices with set prices. In terms of desktops, Apple has only one geared towards consumers, so if the cost is prohibitive, a Windows desktop will be a much better choice.
- PCs are more up-gradable and configurable. On Macs, you can usually only upgrade the RAM or hard drive and that’s it. Pretty much every component on a desktop PC can be switched out. When purchasing PCs, you also have a lot more options that you can configure including processors, cases, memory, hard drives, ports, displays, etc.
- Overall, there is a lot more software available for Windows than for PC. The opposite is true when you look at smartphones, but we’re talking about computers here. There is usually an equivalent Mac program for every Windows app, but they are not always as good.
- Windows based PCs may have greater backwards compatibility. A five year old PC can easily run Windows 10 without any issue. A five year old Mac can run the latest version of OS X, but half the features will be missing and things don’t run as smoothly. For some reason, you always need the latest Mac in order to utilize all the new features in OS X.
- PCs are the absolute best option when it comes to gaming. Macs simply do not come with as powerful graphics cards, even high-end machines like the Mac Pro.
- Worldwide, most computers are PCs and Windows is the most popular operating system by far. This means the community is much larger and you can get more support for software and hardware.
- In terms of accessories, PCs have a lot more options and those options are usually cheaper.
- Though OS X is simpler, that’s not always the best for some people. Windows is more complex and powerful than OS X.
- PCs can be configured with hardware that Apple considers obsolete. Some newer Apple machines don’t even come with CD/DVD drives. It also seems Apple keeps reducing the number of ports on each newer machine. The new Macbook has one USB port and one headphone jack and that’s it.
- PCs work great with a whole slew of other products too. For example, you can stream your Xbox or PlayStation games to Windows.
These are some of the major pros and cons when it comes to Mac and PCs. There are a ton of other smaller pluses and minuses, but I don’t think those warrant that much attention when discussing this topic in general terms. Obviously, if you’re a professional graphics designer, then looking at specific compatible hardware and software would make more sense.
The point of this article is not to say one platform is better than the other, because that is simply not true. If you are a college student and the only thing that matters to you is your budget, then a Mac will probably not be best choice, regardless of the other benefits. In my opinion, if you have never tried a Mac, you should ask a friend or family member to loan you a device to see how you feel about it. Just about everyone has used Windows, so you pretty much know what you are getting in terms of software.
